a. The future value after 7 years is approximately $139,485.49.
b. The amount found with continuous compounding yields approximately $18,075.04 more than the amount found with annual compounding.
a. To find the future value of $90,000 invested at 8% compounded annually for 7 years, we can use the formula for compound interest:
Future Value = Principal * (1 + Rate/100)^Time
Future Value = $90,000 * (1 + 8/100)^7
Future Value ≈ $139,485.49
Therefore, the future value after 7 years is approximately $139,485.49.
b. In part (b), it is stated that the future value of $90,000 invested at 8% interest, compounded continuously, is $157,560.53.
To compare the result from part (a) to part (b), we calculate the difference:
Difference = Future Value (Continuous Compounding) - Future Value (Annual Compounding)
Difference = $157,560.53 - $139,485.49
Difference ≈ $18,075.04
Therefore, the amount found with continuous compounding yields approximately $18,075.04 more than the amount found with annual compounding.
The result from part (b) shows that continuous compounding generates a higher future value compared to annual compounding. The difference between the two approaches is approximately $18,075.04.

What angular resolution would you need to see the Sun and Jupiter as distinct points of light? Express your answer in arcseconds to two significant figures. Jupiter 195| ΑΣΦ % ? 11 Suppose you were looking at our own solar system from a distance of 6.0 light-years.
An angular resolution of 0.56 arcseconds is required to see the Sun and Jupiter as separate objects. This is an extremely small angle and would necessitate the use of a large telescope.
Angular resolution is defined as the minimum angle between two objects that enables a viewer to see them as distinct objects rather than as a single one. A better angular resolution corresponds to a smaller minimum angle. The angular resolution formula is θ = 1.22 λ / D, where λ is the wavelength of light and D is the diameter of the telescope. Thus, the angular resolution formula can be expressed as the smallest angle between two objects that allows a viewer to distinguish between them. In arcseconds, the answer should be given to two significant figures.
To see the Sun and Jupiter as distinct points of light, we need to have a good angular resolution. The angular resolution is calculated as follows:
θ = 1.22 λ / D, where θ is the angular resolution, λ is the wavelength of the light, and D is the diameter of the telescope.
Using this formula, we can find the minimum angular resolution required to see the Sun and Jupiter as separate objects. The Sun and Jupiter are at an average distance of 5.2 astronomical units (AU) from each other. An AU is the distance from the Earth to the Sun, which is about 150 million kilometers. This means that the distance between Jupiter and the Sun is 780 million kilometers.
To determine the angular resolution, we need to know the wavelength of the light and the diameter of the telescope. Let's use visible light (λ = 550 nm) and assume that we are using a telescope with a diameter of 2.5 meters.
θ = 1.22 λ / D = 1.22 × 550 × 10^-9 / 2.5 = 2.7 × 10^-6 rad
To convert radians to arcseconds, multiply by 206,265.θ = 2.7 × 10^-6 × 206,265 = 0.56 arcseconds
The angular resolution required to see the Sun and Jupiter as distinct points of light is 0.56 arcseconds.
This is very small and would require a large telescope to achieve.
In conclusion, we require an angular resolution of 0.56 arcseconds to see the Sun and Jupiter as separate objects. This is an extremely small angle and would necessitate the use of a large telescope.

How long will it take for the rocket to hit the ground? Show your work and explain your reasoning. c. At what time was the rocket at its maximum height? What was the maximum height of the rocket?
To find the height from which the rocket was launched, we need to determine the initial height when time (t) is equal to 0. In the given equation, [tex]h = -5t^2 + 30t + 80[/tex]. Plugging in t = 0, we get [tex]h = -5(0)^2 + 30(0) + 80 = 80[/tex]. Therefore, the rocket was launched from a height of 80 feet.
To calculate the time it takes for the rocket to hit the ground, we need to find the value of t when h = 0. In the given equation, [tex]h = -5t^2 + 30t + 80[/tex]. Setting h = 0, we get [tex]-5t^2 + 30t + 80 = 0[/tex]. We can solve this quadratic equation using factoring, completing the square, or the quadratic formula. Factoring gives us (-5t - 8)(t - 10) = 0. Therefore, either -5t - 8 = 0 or t - 10 = 0. Solving these equations gives us t = -8/5 or t = 10. Since time cannot be negative in this context, the rocket will hit the ground after approximately 10 seconds.
To determine the time when the rocket reaches its maximum height and the corresponding maximum height, we can analyze the given quadratic equation. The equation [tex]h = -5t^2 + 30t + 80[/tex] represents a parabolic function with a coefficient of -5 for the [tex]t^2[/tex] term, indicating a downward-facing parabola. The maximum point of the parabola occurs at the vertex. The t-coordinate of the vertex can be found using the formula [tex]t = -b/(2a)[/tex], where a = -5 and b = 30. Substituting these values, we get [tex]t = -30/(2\times -5) = 3 seconds[/tex]. To find the maximum height, we substitute this value of t into the equation to obtain [tex]h = -5(3)^2 + 30(3) + 80 = 95 feet[/tex]. Therefore, the rocket reaches its maximum height of 95 feet at 3 seconds.

Use the method of variation of parameters to find a particular solution of the given differential equation: y'' - 2y' - 8y = 3e⁻²ˣ
To find a particular solution of the differential equation y'' - 2y' - 8y = 3e^(-2x), we can use the method of variation of parameters.
The particular solution can be found by assuming a solution of the form y_p(x) = u(x)e^(-2x), where u(x) is a function to be determined.
The given differential equation is a linear homogeneous second-order ordinary differential equation with constant coefficients. To find a particular solution using the method of variation of parameters, we first find the solutions of the associated homogeneous equation, which is obtained by setting the right-hand side to zero.
The characteristic equation of the homogeneous equation is r^2 - 2r - 8 = 0, which factors as (r - 4)(r + 2) = 0. Therefore, the fundamental solutions are y_1(x) = e^(4x) and y_2(x) = e^(-2x).
Next, we assume a particular solution of the form y_p = u_1(x)y_1(x) + u_2(x)y_2(x), where u_1(x) and u_2(x) are functions to be determined. We differentiate y_p to find its first and second derivatives, and substitute these derivatives into the differential equation. Equating the coefficients of like terms, we obtain a system of equations for u_1'(x) and u_2'(x).
To find u_1(x) and u_2(x), we can solve this system of equations. Once u_1(x) and u_2(x) are determined, the particular solution y_p(x) can be expressed as y_p(x) = u_1(x)e^(4x) + u_2(x)e^(-2x).
Solving the system of equations, we can find the values of u_1(x) and u_2(x). Finally, we substitute these values back into the particular solution expression to obtain the specific form of the particular solution y_p(x) for the given differential equation.

Consider a credit card with a balance of $8500 and an APR of 14.5 %. If you want to make monthly payments in order to pay off the balance in 3 years, what is the total amount you will pay? Round your answer to the nearest cent, if necessary.
The total amount you will pay to pay off the credit card balance in 3 years is approximately $9,786.48.
To calculate the total amount you will pay to pay off the credit card balance, we need to consider the monthly payments required to eliminate the balance in 3 years.
First, we need to determine the monthly interest rate by dividing the annual percentage rate (APR) by 12 (number of months in a year):
Monthly interest rate = 14.5% / 12
= 0.145 / 12
= 0.01208
Next, we need to calculate the total number of months in 3 years:
Total months = 3 years * 12 months/year
= 36 months
Now, we can use the formula for the monthly payment on a loan, assuming equal monthly payments:
Monthly payment [tex]= Balance / [(1 - (1 + r)^{(-n)}) / r][/tex]
where r is the monthly interest rate and n is the total number of months.
Plugging in the values:
Monthly payment = $8500 / [(1 - (1 + 0.01208)*(-36)) / 0.01208]
Evaluating the expression, we find the monthly payment to be approximately $271.83.
Finally, to calculate the total amount paid, we multiply the monthly payment by the total number of months:
Total amount paid = Monthly payment * Total months
Total amount paid = $271.83 * 36

The chi-square test statistic is 1.875, and the critical value (for 4 degrees of freedom and a significance level of 0.05) is 9.488. Therefore, there is not sufficient evidence to reject the null hypothesis that the responses occur with the same frequency.
Given information:
Sample data for responses to a multiple-choice test question:
Response: B CD H
Frequency: 12 15 16 18 19
Null Hypothesis:
The null hypothesis states that the responses occur with the same frequency.
Alternative Hypothesis:
The alternative hypothesis states that the responses do not occur with the same frequency.
Test Statistic:
For a goodness-of-fit test, we use the chi-square [tex](\(\chi^2\))[/tex] test statistic. The formula for the chi-square test statistic is:
[tex]\(\chi^2 = \sum \frac{{(O_i - E_i)^2}}{{E_i}}\)[/tex]
where [tex](O_i)[/tex] represents the observed frequency and [tex]\(E_i\)[/tex] represents the expected frequency for each category.
To perform the goodness-of-fit test, we need to calculate the expected frequencies under the assumption of the null hypothesis. Since the null hypothesis states that the responses occur with the same frequency, the expected frequency for each category can be calculated as the total frequency divided by the number of categories.
Expected frequency for each category:
Total frequency = 12 + 15 + 16 + 18 + 19 = 80
Expected frequency = Total frequency / Number of categories = 80 / 5 = 16

The graph will start at (0, 2), then move in a downward curve to (π/4, -4), continue in an upward curve to (π/2, -1), and finally, curve back downward to (3π/4, 2).
To graph one cycle of a cosine function with the given parameters, we can start by determining the key points and values that will help us construct the graph.
The amplitude of the cosine function is 3, which means the highest and lowest points of the graph will be 3 units above and below the midline. Since the midline is y = -1, the highest point will be at y = 3 - 1 = 2, and the lowest point will be at y = -3 - 1 = -4.
The period of the function is π/2, which means it completes one full cycle within this interval. We can divide the period into four equal parts to find the x-values for the key points. The x-values for these points will be 0, π/4, π/2, and 3π/4.
Since we know that the point (0, 2) lies on the graph, we can plot it as the starting point. From there, we can construct the graph using the key points we determined earlier.
The graph will start at (0, 2), then move to (π/4, -4), (π/2, -1), and finally, (3π/4, 2). Connecting these points will give us one cycle of the cosine function.

Find the projection of u onto v. u = (4,4) (6, 1) V = proj,u = Write u as the sum of two orthogonal vectors, one of which is proj,u. u = proj u +
The projection of vector u onto vector v is (4, 4). Vector u can be expressed as the sum of two orthogonal vectors: the projection of u onto v and the component orthogonal to v.
To find the projection of vector u onto vector v, we can use the formula for projection: proj_v(u) = (u · v) / (v · v) * v, where · represents the dot product. Given that u = (4, 4) and v = (6, 1), we can calculate the dot product of u and v as (4 * 6) + (4 * 1) = 24 + 4 = 28, and the dot product of v with itself as (6 * 6) + (1 * 1) = 36 + 1 = 37.
Substituting these values into the projection formula, we get proj_v(u) = (28 / 37) * (6, 1) = (168/37, 28/37). Therefore, the projection of u onto v is (4, 4).
To express u as the sum of two orthogonal vectors, we can use the orthogonal decomposition theorem. According to this theorem, any vector can be decomposed into the sum of its projection onto a subspace and its component orthogonal to that subspace. In this case, we can write u as u = proj_v(u) + u_orthogonal, where u_orthogonal is the component of u orthogonal to v.
Since we have already found proj_v(u) to be (4, 4), we can subtract this projection from u to obtain the orthogonal component: u_orthogonal = u - proj_v(u) = (4, 4) - (4, 4) = (0, 0). Therefore, u can be expressed as u = (4, 4) + (0, 0), where (4, 4) is the projection of u onto v and (0, 0) is the orthogonal component.

a) Compute diver angular velocity when she assumes a tuck position, altering her radius of gyration to 0.2 m.
When the diver assumes a tuck position with a new radius of gyration of 0.2 m, her angular velocity becomes 20 rad/s.
To compute the diver's angular velocity when she assumes a tuck position with a new radius of gyration, we can use the principle of conservation of angular momentum.
The principle of conservation of angular momentum states that the angular momentum of a system remains constant unless acted upon by an external torque. Mathematically, it can be expressed as:
L1 = L2
where L1 is the initial angular momentum and L2 is the final angular momentum.
In this case, the initial angular momentum of the diver can be calculated as:
L1 = I1 * ω1
where I1 is the moment of inertia and ω1 is the initial angular velocity.
Given that the initial radius of gyration is 0.4 m and the initial angular velocity is 5 rad/s, we can determine the moment of inertia using the formula:
[tex]I1 = m * k1^2[/tex]
where m is the mass of the diver and k1 is the initial radius of gyration.
Substituting the values, we have:
[tex]I1 = 50 kg * (0.4 m)^2 = 8 kgm^2[/tex]
Next, we calculate the final angular momentum, L2, using the new radius of gyration, k2 = 0.2 m:
[tex]I2 = m * k2^2 = 50 kg * (0.2 m)^2 = 2 kgm^2[/tex]
Since angular momentum is conserved, we have:
L1 = L2
[tex]I1 * ω1 = I2 * ω2[/tex]
Solving for ω2, the final angular velocity, we can rearrange the equation:
[tex]ω2 = \frac{ (I1 * \omega 1)}{I2}[/tex]
Substituting the values, we get:
[tex]\omega2 = \frac{(8 kgm^2 * 5 rad/s)}{2 kgm^2 =}[/tex] = 20 rad/s.
Therefore, when the diver assumes a tuck position with a new radius of gyration of 0.2 m, her angular velocity becomes 20 rad/s.

If f:A⟶B and g:B⟶C are functions and g∘f is one-to-one, g must be one-to-one. If f:A⟶B and g:B⟶C are functions and g∘f is onto, g must be onto. If f:A⟶B and g:B⟶C are functions and g∘f is one-to-one, f must be one-to-one. If f:A⟶B and g:B⟶C are functions and g∘f is one-to-one, f must be onto.
The statements that are not true for all sets A, B ⊆ U are statements 1 and 2. On the other hand, statements 3 and 4 are true and hold for all sets and functions.
The statements that are not true for all sets A, B ⊆ U are:
If f: A ⟶ B and g: B ⟶ C are functions and g∘f is one-to-one, g must be one-to-one.
Counterexample: Let A = {1}, B = {2}, C = {3}, and define f and g as follows: f(1) = 2 and g(2) = 3. In this case, g∘f is one-to-one since there is only one element in A. However, g is not one-to-one because g(2) = g(1) = 3.
If f: A ⟶ B and g: B ⟶ C are functions and g∘f is onto, g must be onto.
Counterexample: Let A = {1}, B = {2}, C = {3}, and define f and g as follows: f(1) = 2 and g(2) = 3. In this case, g∘f is onto since every element in C is mapped to by some element in A. However, g is not onto because there is no element in B that maps to 3.
If f: A ⟶ B and g: B ⟶ C are functions and g∘f is one-to-one, f must be one-to-one.
This statement is true. If g∘f is one-to-one, it means that for any two distinct elements a, a' in A, we have g(f(a)) ≠ g(f(a')). This implies that f(a) and f(a') are distinct, so f must be one-to-one.
If f: A ⟶ B and g: B ⟶ C are functions and g∘f is one-to-one, f must be onto.
Counterexample: Let A = {1}, B = {2}, C = {3}, and define f and g as follows: f(1) = 2 and g(2) = 3. In this case, g∘f is one-to-one since there is only one element in A. However, f is not onto because there is no element in A that maps to 3.

Therefore, f(2/3) = -14/9.(d) To find: f(4x)Substitute x = 4x in f(x), we get:f(4x) = (4x)² - 3(4x) + 2f(4x) = 16x² - 12x + 2
Therefore, f(4x) = 16x² - 12x + 2.(e) To find: 4f(x)Multiply f(x) by 4, we get:4f(x) = 4(x² - 3x + 2)4f(x) = 4x² - 12x + 8
Therefore, 4f(x) = 4x² - 12x + 8.(f) To find: f(-x)Substitute x = -x in f(x), we get:f(-x) = (-x)² - 3(-x) + 2f(-x) = x² + 3x + 2
Therefore, f(-x) = x² + 3x + 2.(g) To find: f(x - 4)Substitute x - 4 in f(x), we get:f(x - 4) = (x - 4)² - 3(x - 4) + 2f(x - 4) = x² - 8x + 18
Therefore, f(x - 4) = x² - 8x + 18.(h) To find: f(x) - 4Substitute f(x) - 4 in f(x), we get:f(x) - 4 = (x² - 3x + 2) - 4f(x) - 4 = x² - 3x - 2
Therefore, f(x) - 4 = x² - 3x - 2.(i) To find: f(x²)Substitute x² in f(x), we get:f(x²) = (x²)² - 3(x²) + 2f(x²) = x⁴ - 3x² + 2
Therefore, f(x²) = x⁴ - 3x² + 2. For f(x)=x²−3x+2, the following can be found using the formula given above:(a) f(3) = 2(b) f(-1) = 6(c) f(2/3) = -14/9(d) f(4x) = 16x² - 12x + 2(e) 4f(x) = 4x² - 12x + 8(f) f(-x) = x² + 3x + 2(g) f(x-4) = x² - 8x + 18(h) f(x) - 4 = x² - 3x - 2(i) f(x²) = x⁴ - 3x² + 2.

Assuming that someone is asked to write a code (i.e., program) for nonlinear problem using least square adjustment technique, what would be your advice for this person to terminate the program?
This criterion can be defined based on the desired level of accuracy or when the change in the estimated parameters falls below a certain threshold.
When implementing a program for a nonlinear problem using the least square adjustment technique, it is essential to determine a termination condition. This condition dictates when the program should stop iterating and provide the final estimated parameters. A common approach is to set a convergence criterion, which measures the change in the estimated parameters between iterations.
One possible criterion is to check if the change in the estimated parameters falls below a predetermined threshold. This implies that the adjustment process has reached a point where further iterations yield minimal improvements. The threshold value can be defined based on the desired level of accuracy or the specific requirements of the problem at hand.
Alternatively, convergence can also be determined based on the objective function. If the objective function decreases below a certain tolerance or stabilizes within a defined range, it can indicate that the solution has converged.
Considering the chosen termination condition is crucial to ensure that the program terminates effectively and efficiently, providing reliable results for the nonlinear problem.

A mass of 1 slug is attached to a spring whose constant is 5lb/ft. Initially, the mass is released 1 foot below the equilibrium position with a downward velocity the equation of motion if the mass is driven by an external force equal to f(t)=12cos(2t)+3sin(2t)
1 * x'' + 5 * x = 12cos(2t) + 3sin(2t)
This is the differential equation that describes the motion of the mass driven by the given external force.
To find the equation of motion for the mass driven by the external force, we need to solve the differential equation that describes the system. The equation of motion for a mass-spring system with an external force is given by:
m * x'' + c * x' + k * x = f(t)
where:
m is the mass (1 slug),
x is the displacement of the mass from its equilibrium position,
c is the damping constant (assumed to be 0 in this case),
k is the spring constant (5 lb/ft), and
f(t) is the external force (12cos(2t) + 3sin(2t)).
Since there is no damping in this system, the equation becomes:
m * x'' + k * x = f(t)
Substituting the given values:
1 * x'' + 5 * x = 12cos(2t) + 3sin(2t)
This is the differential equation that describes the motion of the mass driven by the given external force.

• To keep the follower fully raised through next θ2°;
• To lower the follower during next θ3° with cycloidal motion and
• To keep the follower down to its original position during rest of the revolution.
Follower Displacement, Y mm = 52
angle of rise θ1° = 150°
angle of first dwell θ2° = 30°
angle of return θ3° = 90°
Clearly draw the follower displacement diagram using basic drawing instruments
Clearly draw the profile of the cam using the graphical method
Clear solution pls. thanks!
The basic drawing instruments were used to draw the follower displacement diagram for a cam with a base circle diameter of 80 mm rotating clockwise at a uniform speed to provide an in-line roller follower with a 10 mm radius at the end of a valve rod, as specified in the question.
A graphical approach was used to draw the cam profile.The motion of a cam and roller follower mechanism can be represented by the follower displacement diagram, which indicates the follower's height as a function of the cam's angle of rotation. The follower's height is determined by the shape of the cam, which is created by tracing the follower displacement diagram. In this instance, the follower's displacement is described in terms of simple harmonic motion, cycloidal motion, and periods of constant height.
To construct the follower displacement diagram, the follower's maximum displacement of 52 mm is plotted along the y-axis, while the cam's angle of rotation, which covers a full revolution of 360°, is plotted along the x-axis. The diagram can be split into four sections, each of which corresponds to a different motion period.The first section, which covers an angle of 150°, represents the time during which the follower is raised through Y mm with simple harmonic motion. The maximum displacement is reached at an angle of 75°, and the follower returns to its original position after the angle of 150° has been covered.The second section, which covers an angle of 30°, represents the time during which the follower is fully raised. The follower remains at the maximum displacement height for the duration of this period.
The third section, which covers an angle of 90°, represents the time during which the follower is lowered with cycloidal motion. The lowest point is reached at an angle of 180°, and the follower returns to its original position after the angle of 270° has been covered.The final section, which covers an angle of 90°, represents the time during which the follower is at its original position. The angle of 360° is reached at the end of this period. To complete the drawing of the cam, the follower displacement diagram was used to generate the cam profile using a graphical method.
The cam profile was created by tracing the path of the follower displacement diagram with a flexible strip of material, such as paper or plastic, and transferring the resulting curve to a graph with the cam's angle of rotation plotted along the x-axis and the height of the cam above the base circle plotted along the y-axis. The curve's peak, corresponding to the maximum displacement of 52 mm in the follower displacement diagram, is at an angle of 75° in the cam profile, just as it is in the follower displacement diagram.
The cam profile is cycloidal in shape in this instance. The maximum height of the cam profile, which corresponds to the maximum follower displacement height, is 62 mm. In conclusion, the follower displacement diagram and cam profile for a cam with a base circle diameter of 80 mm rotating clockwise at a uniform speed and producing an in-line roller follower with a 10 mm radius at the end of a valve rod were drawn using basic drawing instruments.

We can determine the final balance for Leroy Ltd. In this case, the final balance is $27,612.00, which matches the balance on the company's books.
To reconcile the bank statement for Leroy Ltd., we need to consider the various transactions and adjustments. Let's define the following variables:
OB = Opening balance provided by the bank statement ($9,394.00)
EFT = Electronic funds transfer ($710.25)
AP = Automatic payment ($305.00)
SC = Service charge ($6.75)
NSF = Non-sufficient funds charge ($15.55)
DT = Total amount of deposits in transit ($13,375.00)
OC = Total amount of outstanding cheques ($4,266.00)
BB = Balance on the company's books ($18,503.00)
FB = Final balance after reconciliation (to be determined)
Based on the given information, we can set up the reconciliation process as follows:
Start with the opening balance provided by the bank statement: FB = OB
Add the deposits in transit to the FB: FB += DT
Subtract the outstanding cheques from the FB: FB -= OC
Deduct any bank charges or fees from the FB: FB -= (SC + NSF)
Deduct any payments made by the company (EFT and AP) from the FB: FB -= (EFT + AP)

The given signal is, y[n] = nx[n] .It needs to be analyzed if the given system is linear, time invarient, causal, stable, and invertible.
Linear: We know a system is linear if it follows the superposition principle. That is, if x1[n] → y1[n] and x2[n] → y2[n] are two input-output pairs, then for any constants a1 and a2, we must have a1x1[n] + a2x2[n] → a1y1[n] + a2y2[n]. Hence, in this case, we must check if the superposition principle holds true. The given system is linear because n is simply a constant, and the multiplication of any constant with a signal does not change its linearity property. Therefore, y1[n] = n x1[n] and y2[n] = n x2[n] and a1y1[n] + a2y2[n] = a1 (n x1[n]) + a2 (n x2[n]) = n (a1x1[n] + a2x2[n]) satisfies the superposition principle.
- Time invarient: A system is time-invariant if its output does not depend on the absolute value of time. Thus, a time-invariant system does not change its properties over time. Hence, in this case, we must check if the system is time-invariant. The given system is time-invariant as it does not explicitly depend on time. The function of n is merely to scale the input by a constant value. As scaling the input does not change its position on the time-axis, the system is time-invariant.
- Causal: A system is causal if its output only depends on the present and past values of the input. The output must not be affected by future values of the input. Hence, in this case, we must check if the system is causal. The given system is not causal because the value of y[n] depends on the future value of the input. The value of y[n] is n times the value of x[n]. Therefore, if the value of x[n] at a future time is changed, the value of y[n] will also change, which violates the causality property.
- Stable: A system is stable if its output does not diverge for any bounded input. A bounded input is an input signal that does not go to infinity. Hence, in this case, we must check if the system is stable. The given system is unstable as it multiplies the input signal with n, which increases unboundedly.
- Invertible: A system is invertible if distinct inputs have distinct outputs. In other words, if x1[n] and x2[n] are two inputs such that x1[n] ≠ x2[n], then y1[n] ≠ y2[n]. Hence, in this case, we must check if the system is invertible. The given system is not invertible because different inputs may yield the same output.
he given system is linear and time-invariant. It is not causal, unstable, and invertible.

Given sec(x)=−8 with 90° < x < 180°. Find sin(2x)
(ii) Given sin(x)=−6/7 with 180° < x < 270°. Find sin(2x)
iii) Given csc(x)=−2 with 270° < x < 360°. Find cos(2x)
The answer to the problem is cos(2x) = 1/2
The relationship sin2(x) + cos2(x) = 1 and the fact that sec(x) is the reciprocal of cos(x) allow us to calculate cos(x) given sec(x) = -8 with 90° x 180°:
x's sec(x) = 1/cos(x) = -8
1/cos(x) = -8
cos(x) = -1/8
Now, we can apply the double-angle identity for sine to find sin(2x):
Sin(2x) equals 2sin(x)cos(x).
Since the range of x is 90° to x > 180° and we know that cos(x) = -1/8, we can calculate sin(x) using the identity sin2(x) + cos2(x) = 1:
sin²(x) + (-1/8)² = 1
sin²(x) + 1/64 = 1
sin²(x) = 1 - 1/64
sin²(x) = 63/64
sin(x) = ± √(63/64)
sin(x) = ± √63/8
Now, we can substitute sin(x) and cos(x) into the double-angle formula:
sin(2x) = 2(sin(x))(cos(x))
sin(2x) = 2(± √63/8)(-1/8)
sin(2x) = ± √63/32
(ii) Given sin(x) = -6/7 with 180° < x < 270°, we want to find sin(2x).
Using the double-angle identity for sine:
sin(2x) = 2sin(x)cos(x)
Since we know sin(x) = -6/7 and the range of x is 180° < x < 270°, we can determine cos(x) using the identity sin²(x) + cos²(x) = 1:
(-6/7)² + cos²(x) = 1
36/49 + cos²(x) = 1
cos²(x) = 1 - 36/49
cos²(x) = 13/49
cos(x) = ± √(13/49)
cos(x) = ± √13/7
Now, we can substitute sin(x) and cos(x) into the double-angle formula:
sin(2x) = 2(sin(x))(cos(x))
sin(2x) = 2(-6/7)(√13/7)
sin(2x) = -12√13/49
(iii) Given csc(x) = -2 with 270° < x < 360°, we want to find cos(2x).
Using the identity csc(x) = 1/sin(x), we can determine sin(x):
1/sin(x) = -2
sin(x) = -1/2
Since the range of x is 270° < x < 360°, we know that sin(x) is negative in this range. Therefore, sin(x) = -1/2.
Now, we can use the identity sin²(x) + cos²(x) = 1 to find cos(x):
(-1/2)² + cos²(x) = 1
1/4 + cos²(x) = 1
cos²(x) = 3/4
cos(x) = ± √(3/4)
cos(x) = ± √3/2
The double-angle identity for cosine can be used to determine cos(2x):
cos(2x) equals cos2(x) - sin2(x).
The values of sin(x) and cos(x) are substituted:
cos(2x) = (√3/2)² - (-1/2)² cos(2x) = 3/4 - 1/4
cos(2x) = 2/4
cos(2x) = 1/2

Alexei will catch up with Rahquez after 2 hours when Alexei left traveling the same direction.
Given that
Rahquez left the park traveling 4 mph and 4 hours later, Alexei left traveling the same direction at 12 mph.

When the foundation of a 1-DOF (Degree of Freedom) mass-spring system with a natural frequency ωn causes displacement as a unit step function, the displacement response of the system can be obtained using the step response formula.
The displacement response of the system, denoted as y(t), can be expressed as:
y(t) = (1 - cos(ωn * t)) / ωn
where t represents time and ωn is the natural frequency of the system.
In this case, the unit step function causes an immediate change in the system's displacement. The displacement response gradually increases over time and approaches a steady-state value. The formula accounts for the dynamic behavior of the mass-spring system, taking into consideration the system's natural frequency.
By substituting the given natural frequency ωn into the step response formula, you can calculate the displacement response of the system at any given time t. This equation provides a mathematical representation of how the system responds to the unit step function applied to its foundation.

1. Seanna O'Brien receives pension payments of $3,200 at the end of every six months from a retirement fund of $50,000. The fund earns 7% compounded semi-annually. What is the size of the final pension payment? ( 5 marks)
The size of the final pension payment received by Seanna O'Brien will depend on the remaining balance in her retirement fund after approximately 11.5 years, when the fund reaches zero.
The size of the final pension payment received by Seanna O'Brien can be determined using the concept of compound interest. With a retirement fund of $50,000 and an interest rate of 7% compounded semi-annually, Seanna receives pension payments of $3,200 at the end of every six months. The objective is to find the size of the final pension payment.
To calculate the final pension payment, we need to determine the number of compounding periods required for the retirement fund to reach zero. Each pension payment of $3,200 reduces the retirement fund by that amount. Since the interest is compounded semi-annually, the interest rate for each period is 7%/2 = 3.5%. Using the compound interest formula, we can calculate the number of periods required:
50,000 * (1 + 3.5%)^n = 3,200
Solving for 'n', we find that it takes approximately 23 periods (or 11.5 years) for the retirement fund to reach zero. The final pension payment will occur at the end of this period, and its size will depend on the remaining balance in the retirement fund at that time.
In conclusion, the size of the final pension payment received by Seanna O'Brien will depend on the remaining balance in her retirement fund after approximately 11.5 years, when the fund reaches zero.
