The company can earn a maximum of $2760 if it sells 10 Tire X tires and 18 Tire Y tires.

A tire company sells two different tread patterns of tires. Tire X is priced at $75.00 and Tire Y is priced at $85.00. It is given that the three times the number of Tire Y sold must be less than or equal to twice the number of Tire X sold. The company has at most 300 tires to sell. Let the number of Tire X sold be x.

Then the number of Tire Y sold is 3y. The cost of the x Tire X and 3y Tire Y tires can be expressed as follows:

75x + 85(3y) ≤ 300 …(1)

75x + 255y ≤ 300

Divide both sides by 15. 5x + 17y ≤ 20

This is the required inequality that represents the number of tires sold.The given inequality 3y ≤ 2x can be re-written as follows: 2x - 3y ≥ 0 3y ≤ 2x ≤ 20, x ≤ 10, y ≤ 6

Therefore, the company can sell at most 10 Tire X tires and 18 Tire Y tires at the most.

Therefore, the maximum amount the company can earn is as follows:

Maximum earnings = (10 x $75) + (18 x $85) = $2760

Therefore, the company can earn a maximum of $2760 if it sells 10 Tire X tires and 18 Tire Y tires.

Let's assume the cost of one bag of rice is R, and the cost of one bag of sugar is S.

From the given information, we can form the following system of equations:

5R + 2S = 164.50 (Equation 1)

3R + 4S = 150.50 (Equation 2)

To solve this system, we can use the method of substitution or elimination. Here, we'll use the elimination method to eliminate the variable R.

Multiplying Equation 1 by 3 and Equation 2 by 5 to make the coefficients of R equal:

15R + 6S = 493.50 (Equation 3)

15R + 20S = 752.50 (Equation 4)

If a cyclist travels from city A to city B at a constant speed of 12 km/h and takes 2 hours, it would take 3 hours to complete the same trip at a speed of 8 km/h.

To determine the time it would take to make the same trip at 8 km/h, we can use the concept of speed and distance. The relationship between speed, distance, and time is given by the formula:

Time = Distance / Speed

In the given scenario, the cyclist travels from city A to city B at a constant speed of 12 km/h and takes 2 hours to complete the journey. This means the distance between city A and city B can be calculated by multiplying the speed (12 km/h) by the time (2 hours):

Distance = Speed * Time = 12 km/h * 2 hours = 24 km

Now, let's calculate the time it would take to make the same trip at 8 km/h. We can rearrange the formula to solve for time:

Time = Distance / Speed

Substituting the values, we have:

Time = 24 km / 8 km/h = 3 hours

For the given continuous data distribution with frequencies, we need to determine the quartile deviation and the value of Q-1.

To calculate the quartile deviation, we first find the cumulative frequencies for the given intervals: 3, 8 (3 + 5), 15 (3 + 5 + 7), and 16 (3 + 5 + 7 + 1). Next, we determine the values of Q1 and Q3.

Using the cumulative frequencies, we find that Q1 falls within the interval 20-30. Interpolating within this interval using the formula Q1 = L + ((n/4) - F) x (I / f), where L is the lower limit of the interval, F is the cumulative frequency of the preceding interval, I is the width of the interval, and f is the frequency of the interval, we obtain Q1 = 22.

For the quartile deviation, we calculate the difference between Q3 and Q1. However, since the options provided do not include the quartile deviation, we cannot determine its exact value.

In summary, the value of Q1 is 22, but the quartile deviation cannot be determined without additional information.

Based on the present worth analysis, Process A should be chosen as it has a lower present worth compared to Process B.

Process A

Process B

Interest rate = 14% per year

The formula for calculating the present worth is given by:

Present Worth (PW) = Future Worth (FW) / (1+i)^n

Where i is the interest rate and n is the number of years.

Process A is used for 4 years.

Therefore, Future Worth (FW) for Process A will be:

FW = Salvage value + Annual operating cost × number of years

FW = $12,000 + $25,000 × 4

FW = $112,000

Now, we can calculate the present worth of Process A as follows:

PW = 112,000 / (1+0.14)^4

PW = 112,000 / 1.744

PW = $64,263

The parent function for g(x) = x + 2 is the identity function, f(x) = x, which is a straight line passing through the origin with a slope of 1.

To graph g(x) = x + 2, we start with the parent function and apply the transformation. The transformation for g(x) involves shifting the graph vertically upward by 2 units.

Here's the step-by-step process to graph g(x):

Plot points on the parent function, f(x) = x. For example, if x = -2, f(x) = -2; if x = 0, f(x) = 0; if x = 2, f(x) = 2.

Apply the vertical shift by adding 2 units to the y-coordinate of each point. For example, if the point on the parent function is (x, y), the corresponding point on g(x) will be (x, y + 2).

Connect the points to form a straight line. Since g(x) = x + 2 is a linear function, the graph will be a straight line with the same slope as the parent function.

The transformation of the parent function f(x) = x to g(x) = x + 2 results in a vertical shift upward by 2 units. This means that the graph of g(x) is the same as the parent function, but it is shifted upward by 2 units along the y-axis.

Visually, the graph of g(x) will be parallel to the parent function f(x), but it will be shifted upward by 2 units. The slope of the line remains the same, indicating that the transformation does not affect the steepness of the line.

The particular solution that satisfies the initial conditions is:

\[y(t) = (-3 + t)e^{-\frac{2}{3}t}\]

To solve the given initial value problem, we'll assume that the solution has the form of a exponential function. Let's substitute \(y = e^{rt}\) into the differential equation and find the values of \(r\) that satisfy it.

Starting with the differential equation:

\[9y'' + 12y' + 4y = 0\]

We can differentiate \(y\) with respect to \(t\) to find \(y'\) and \(y''\):

\[y' = re^{rt}\]

\[y'' = r^2e^{rt}\]

Substituting these expressions back into the differential equation:

\[9(r^2e^{rt}) + 12(re^{rt}) + 4(e^{rt}) = 0\]

Dividing through by \(e^{rt}\):

\[9r^2 + 12r + 4 = 0\]

Now we have a quadratic equation in \(r\). We can solve it by factoring or using the quadratic formula. Factoring doesn't seem to yield simple integer solutions, so let's use the quadratic formula:

\[r = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\]

In our case, \(a = 9\), \(b = 12\), and \(c = 4\). Substituting these values:

\[r = \frac{-12 \pm \sqrt{12^2 - 4 \cdot 9 \cdot 4}}{2 \cdot 9}\]

Simplifying:

\[r = \frac{-12 \pm \sqrt{144 - 144}}{18}\]

\[r = \frac{-12}{18}\]

\[r = -\frac{2}{3}\]

Therefore, the roots of the quadratic equation are \(r_1 = -\frac{2}{3}\) and \(r_2 = -\frac{2}{3}\).

Since both roots are the same, the general solution will contain a repeated exponential term. The general solution is given by:

\[y(t) = (c_1 + c_2t)e^{-\frac{2}{3}t}\]

Now let's find the particular solution that satisfies the initial conditions \(y(0) = -3\) and \(y'(0) = 3\).

Substituting \(t = 0\) into the general solution:

\[y(0) = (c_1 + c_2 \cdot 0)e^{0}\]

\[-3 = c_1\]

Substituting \(t = 0\) into the derivative of the general solution:

\[y'(0) = c_2e^{0} - \frac{2}{3}(c_1 + c_2 \cdot 0)e^{0}\]

\[3 = c_2 - \frac{2}{3}c_1\]

Substituting \(c_1 = -3\) into the second equation:

\[3 = c_2 - \frac{2}{3}(-3)\]

\[3 = c_2 + 2\]

\[c_2 = 1\]

Therefore, the particular solution that satisfies the initial conditions is:

\[y(t) = (-3 + t)e^{-\frac{2}{3}t}\]

(a) The largest possible domain for F(x) = 2x² - 6x + 8 is U, the universal set.

Domain: U = [0, ∞) (interval notation)

Since F(x) is a quadratic function, its graph is a parabola opening upwards, and the range is determined by the vertex. In this case, the vertex occurs at the minimum point of the parabola.

To find the largest possible range, we can find the y-coordinate of the vertex.

The x-coordinate of the vertex is given by x = -b/(2a), where a = 2 and b = -6.

x = -(-6)/(2*2) = 3/2

Plugging x = 3/2 into the function, we get:

F(3/2) = 2(3/2)² - 6(3/2) + 8 = 2(9/4) - 9 + 8 = 9/2 - 9 + 8 = 1/2

The y-coordinate of the vertex is 1/2.

Answer: The answer is D (2,3)

Step-by-step explanation:

We are given that triangle PQR lies in the xy-plane, and coordinates of Q are (2,-3).

Triangle PQR is rotated 180 degrees clockwise about the origin and then reflected across the y-axis to produce triangle P'Q'R',

We have to find the coordinates of Q'.

The coordinates of Q(2,-3).

180 degree clockwise  rotation about the origin  then transformation rule

The coordinates (2,-3) change into (-2,3) after 180 degree clockwise rotation about origin.

Reflect across y- axis the transformation rule

Therefore, when reflect across y- axis then the coordinates (-2,3) change into (2,3).

Hence, the coordinates of Q(2,3).

The result of dividing (4x^3 − 2x^2 − 3x + 1) by (x + 3) is a quotient of 4x^2 - 14x + 37 with a remainder of -116.

When dividing polynomials, we use long division. Let's break down the steps:

Divide the first term of the dividend (4x^3) by the first term of the divisor (x) to get 4x^2.

Multiply the entire divisor (x + 3) by the quotient from step 1 (4x^2) to get 4x^3 + 12x^2.

Subtract this result from the original dividend: (4x^3 - 2x^2 - 3x + 1) - (4x^3 + 12x^2) = -14x^2 - 3x + 1.

Bring down the next term (-14x^2).

Divide this term (-14x^2) by the first term of the divisor (x) to get -14x.

Multiply the entire divisor (x + 3) by the new quotient (-14x) to get -14x^2 - 42x.

Subtract this result from the previous result: (-14x^2 - 3x + 1) - (-14x^2 - 42x) = 39x + 1.

Bring down the next term (39x).

Divide this term (39x) by the first term of the divisor (x) to get 39.

Multiply the entire divisor (x + 3) by the new quotient (39) to get 39x + 117.

Subtract this result from the previous result: (39x + 1) - (39x + 117) = -116.

The quotient is 4x^2 - 14x + 37, and the remainder is -116.

Therefore, the result of dividing (4x^3 − 2x^2 − 3x + 1) by (x + 3) is 4x^2 - 14x + 37 with a remainder of -116.

The relative extrema of the function f(x) = x3 - 6x2 - 5 have x-values of 0 and 4, respectively. The relative extrema's equivalent values are -5 and -37, respectively.

To determine the x-values of the relative extrema of the function f(x) = x^3 - 6x^2 - 5, we need to find the critical points where the derivative of the function is equal to zero or does not exist. These critical points correspond to the relative extrema.

1. First, let's find the derivative of the function f(x):
  f'(x) = 3x^2 - 12x

2. Now, we set f'(x) equal to zero and solve for x:
  3x^2 - 12x = 0

3. Factoring out the common factor of 3x, we have:
  3x(x - 4) = 0

4. Applying the zero product property, we set each factor equal to zero:
  3x = 0    or    x - 4 = 0

5. Solving for x, we find two critical points:
  x = 0    or    x = 4

6. Now that we have the critical points, we can determine the values of the relative extrema by plugging these x-values back into the original function f(x).

  When x = 0:
  f(0) = (0)^3 - 6(0)^2 - 5
       = 0 - 0 - 5
       = -5

  When x = 4:
  f(4) = (4)^3 - 6(4)^2 - 5
       = 64 - 6(16) - 5
       = 64 - 96 - 5
       = -37

Therefore, the x-values of the relative extrema of the function f(x) = x^3 - 6x^2 - 5 are x = 0 and x = 4. The corresponding values of the relative extrema are -5 and -37 respectively.

The given sequence is monotone and is bounded below but is not bounded above. Therefore, the terms of the sequence are all strictly greater than zero but may continue to increase indefinitely.

For the sequence (a), the definition is given by: a1 = 1 and a+1 = 1 + an (n ≥ 1).

Therefore,a₂ = 1 + a₁= 1 + 1 = 2

a₃ = 1 + a₂ = 1 + 2 = 3

a₄ = 1 + a₃ = 1 + 3 = 4

a₅ = 1 + a₄ = 1 + 4 = 5 ...

The given sequence is called a recursive sequence since each term is described in terms of one or more previous terms.

For the given sequence (a),

each term of the sequence can be represented as:

a₁ < a₂ < a₃ < a₄ < ... < an

Therefore, the sequence (a) is monotone.

(b)The given sequence is given by: a₁ = 1 and a+1 = 1 + an (n ≥ 1).

Thus, a₂ = 1 + a₁ = 1 + 1 = 2

a₃ = 1 + a₂ = 1 + 2 = 3

a₄ = 1 + a₃ = 1 + 3 = 4...

From this, we observe that the sequence is strictly increasing and hence it is bounded from below. However, the sequence is not bounded from above, hence (2) is not bounded

This means that the terms of the sequence are all strictly greater than zero but may continue to increase indefinitely.

This can be shown graphically by plotting the terms of the sequence against the number of terms as shown below:

Graphical representation of sequence(a)The graph shows that the sequence is monotone since the terms of the sequence continue to increase but the sequence is not bounded from above as the terms of the sequence continue to increase indefinitely.

The name given to this type of design is a factorial design. A factorial design is a design in which researchers investigate the effects of two or more independent variables on a dependent variable.

In this study, two independent variables were used: room color (yellow, blue) and room temperature (20, 24, 28 degrees Celsius), while the dependent variable was happiness.

Each level of each independent variable was tested in conjunction with each level of the other independent variable. There are a total of six experimental conditions (two colors × three temperatures = six conditions), and twenty students were randomly assigned to each of the six conditions.

The researcher then examined how each independent variable and how the interaction of the two independent variables affected the dependent variable (happiness). Therefore, this study is an example of a 2 x 3 factorial design.

The unique solution to the initial value problem is: y = 1 + x + 6x².

To solve the non-homogeneous problem y" = 12(2x²), let's go through the steps:

1) Homogeneous problem:

The homogeneous equation is y" = 0. The auxiliary equation is ar² + br + c = 0.

2) The roots of the auxiliary equation:

Since the coefficient of the y" term is 0, the auxiliary equation simplifies to just c = 0. Therefore, the root of the auxiliary equation is r = 0.

3) Fundamental set of solutions:

For the homogeneous problem y" = 0, since we have a repeated root r = 0, the fundamental set of solutions is Y₁ = 1 and Y₂ = x. So the complementary solution is Yc = C₁(1) + C₂(x) = C₁ + C₂x, where C₁ and C₂ are arbitrary constants.

4) Particular solution:

To find a particular solution, we can use the method of undetermined coefficients. Since the non-homogeneous term is 12(2x²), we assume a particular solution of the form yp = Ax² + Bx + C, where A, B, and C are constants to be determined.

Taking the derivatives of yp, we have:

yp' = 2Ax + B,

yp" = 2A.

Substituting these into the non-homogeneous equation, we get:

2A = 12(2x²),

A = 12x² / 2,

A = 6x².

Therefore, the particular solution is yp = 6x².

5) General solution and initial value problem:

The general solution is the sum of the complementary solution and the particular solution:

y = Yc + yp = C₁ + C₂x + 6x².

To solve the initial value problem y(0) = 1 and y'(0) = 1, we substitute the initial conditions into the general solution:

y(0) = C₁ + C₂(0) + 6(0)² = C₁ = 1,

y'(0) = C₂ + 12(0) = C₂ = 1.

Therefore, the unique solution to the initial value problem is:

y = 1 + x + 6x².

The length and width of an envelope can be calculated as follows:

Solution: Let's assume the width of the envelope to be x.

The length of the envelope will be (x + 4) cm, as per the given conditions.

The area of the envelope is given as 96 cm².

So, the equation for the area of the envelope can be written as: x(x + 4) = 96x² + 4x - 96

The statement "The segment from the center of a square to the corner cannot be called the 'radius' of the square" is false.

The term "radius" is commonly used in the context of circles and spheres, not squares. In geometry, the radius refers to the distance from the center of a circle or a sphere to any point on its boundary. It is a measure of the length between the center and any point on the perimeter of the circle or sphere.

In the case of a square, the equivalent term for the segment from the center to the corner is called the "diagonal." The diagonal of a square is the line segment that connects two opposite corners of the square, passing through its center. It is twice the length of the side of the square.

The given system of equations is inconsistent and has no solution.

To solve the system of equations using augmented matrix methods, we can represent the system in matrix form as:

[tex]\left[\begin{array}{cc}1&2\\2&4\end{array}\right][/tex]  [tex]\left[\begin{array}{ccc}x_1\\x_2\end{array}\right][/tex]  = [tex]\left[\begin{array}{ccc}-4\\8\end{array}\right][/tex]

Augmented Matrix

We can write the augmented matrix as:

[tex]\left[\begin{array}{cc|c}1&2&4\\2&4&-8\end{array}\right][/tex]

Row Operations

We'll perform row operations to transform the augmented matrix into row-echelon form or reduced row-echelon form.

R2 = R2 - 2R1 (Multiply the first row by -2 and add it to the second row)

[tex]\left[\begin{array}{cc|c}1&2&4\\0&0&-16\end{array}\right][/tex]

Interpret the Result

From the row-echelon form of the augmented matrix, we can see that the second equation simplifies to 0 = -16, which is not a valid equation.

This implies that the system of equations is inconsistent and has no solution.

Therefore, the given system of equations:

x₁ + 2x₂ = 4

2x₁ + 4x₂ = -8

has no solution.
