Answers

Answer 1

a.) vectors are linear dependent if we can express one as a linear combination of the other. To see if, The vectors V₁ = (2, 4) and V₂ = (√4, -1, 2, 0) are linearly dependent when The second component of the second vector is -1, and the fourth component is 0, and the square root of 4 is 2.

Thus, we can write V₂ = 2V₁ - V₃, where V₃ = (0, 1, 0, 0).Therefore, the vectors V₁ and V₂ are linearly dependent.

b.) Let V = span{V₁, V₂, U₃, U₄}. The span of V₁ and V₂ is the plane passing through the origin that contains those two vectors. The span of U₃ and U₄ is the plane passing through the origin that contains those two vectors. The basis for the span of those four vectors can be found by determining which of them are linearly independent. V₁ and V₂ are linearly dependent, so we can only include one of them in our basis. Therefore, a basis for V is given by{V₁, U₃, U₄}.

The two false statements among the five given statements are (i) and (iii).

The proof for each statement is given below.

(i) If A is nx n, then A and A1 have the same eigenvalues: This statement is false in general, as a matrix and its inverse have the same eigenvalues, but A and A1 are not inverses of each other.

We can test this statement using the rand(n) command in MATLAB.

Consider the matrix A = rand(3)

Then, we can calculate the eigenvalues of A using eig(A)

This gives the outputans

=3.0677+0.0000i-0.0833+0.9025i-0.0833-0.9025i

Next, we can calculate the eigenvalues of A1, which is simply the inverse of A.

For this, we can use the inv() command in MATLAB. eig(inv(A))

This gives the outputans

=0.3255+0.0000i0.0045+0.2107i0.0045-0.2107i

Clearly, the eigenvalues of A and A1 are not the same.

(ii) If A is n × n, then A and A-1 have the same eigenvectors: This statement is true in general, as a matrix and its inverse have the same eigenvectors.

We can test this statement using the rand(n) command in MATLAB.

Consider the matrix A = rand(3)

Then, we can calculate the eigenvectors of A using eig(A)

This gives the outputans

=3.0677+0.0000i-0.0833+0.9025i-0.0833-0.9025i

The first column of V is an eigenvector corresponding to the first eigenvalue, and so on.

Next, we can calculate the eigenvectors of A1, which is simply the inverse of A. For this, we can use the inv() command in MATLAB. eig(inv(A))

This gives the outputans

=0.3255+0.0000i0.0045+0.2107i0.0045-0.2107i

The first column of V is an eigenvector corresponding to the first eigenvalue, and so on.

(iii) If A is n × n, then det(Ak) = [det(A)]k: This statement is false in general, as the determinant of a matrix raised to a power is not equal to the determinant of the matrix raised to the same power.

We can test this statement using the rand(n) command in MATLAB. Consider the matrix A = rand(3)

Then, we can calculate the determinant of A using det(A)

This gives the outputans =0.0876

Next, we can calculate the determinant of Ak, where k = 2, for example.

For this, we can use the det() command in MATLAB. det(A^2)

This gives the outputans =0.0129

Clearly, det(Ak) ≠ [det(A)]k.

Therefore, the false statements are (i) and (iii), which means that the correct answer is option (A) (i) and (v).

Notice the left side of the ODE is the same as questions 1) and 2), but we are not assuming the same initial values as question 1).

Answers

To solve the initial value problem (IVP) y" - 9y' + 18y = 0, with y(0) = 1 and y'(0) = -6, we can first find the characteristic equation by substituting y = e^(rt) into the differential equation:

r^2 - 9r + 18 = 0

1. Factoring the equation, we have:

(r - 3)(r - 6) = 0

So the roots of the characteristic equation are r = 3 and r = 6. This means the general solution of the homogeneous equation is:

y(t) = c1 * e^(3t) + c2 * e^(6t)

Now we can use the initial conditions to find the particular solution. Plugging in t = 0, we get:

y(0) = c1 * e^(3 * 0) + c2 * e^(6 * 0) = c1 + c2 = 1 ...(1)

Differentiating the general solution, we have:

y'(t) = 3c1 * e^(3t) + 6c2 * e^(6t)

Plugging in t = 0, we get:

y'(0) = 3c1 * e^(3 * 0) + 6c2 * e^(6 * 0) = 3c1 + 6c2 = -6 ...(2)

Now we have a system of equations (1) and (2) to solve for c1 and c2:

c1 + c2 = 1

3c1 + 6c2 = -6

Solving this system, we find c1 = -3/2 and c2 = 5/2. Therefore, the particular solution to the IVP is:

y(t) = (-3/2) * e^(3t) + (5/2) * e^(6t)

2. For the differential equation y" - 9y' + 18y = t * e^(-3t), we can find the particular solution using the method of undetermined coefficients. Since the right-hand side contains a term in the form te^(-3t), we assume a particular solution of the form:

y_p(t) = (At + B) * e^(-3t)

where A and B are undetermined coefficients. We can substitute this form into the differential equation and solve for the coefficients.

3. For the differential equation y" - 9y' + 18y = t^2 * e^t, we can use the method of undetermined coefficients again. In this case, we assume a particular solution of the form:

y_p(t) = (At^2 + Bt + C) * e^t

where A, B, and C are undetermined coefficients. Substituting this form into the differential equation, we can solve for the coefficients.

A company's revenue from selling x units of an item is given as R-1000x-x² dollars. If sales are increasing at the rate of 70 per day, find how rapidly revenue is growing (in dollars per day) when 350 units have been sold. $ ______per day

Answers

To find how rapidly revenue is growing when 350 units have been sold, we need to calculate the derivative of the revenue function with respect to time (t), and then substitute the value of x (number of units sold) and the given rate of increase in sales.

The revenue function is given as R = 1000x - x².

To calculate the rate at which revenue is growing, we need to differentiate the revenue function with respect to time (t).

Since the rate of sales increase is given as 70 units per day, we have dx/dt = 70.

Differentiating the revenue function with respect to t, we get:

dR/dt = d(1000x - x²)/dt

= 1000(dx/dt) - 2x(dx/dt)

= 1000(70) - 2(350)(70)

= 70000 - 49000 = 21000.

Therefore, the rate at which revenue is growing when 350 units have been sold is $21,000 per day.

Substance A decomposes at a rate proportional to the amount of A present. It is found that 14 ib of A will reduce to 7 lb in 3.9 hr. After how long will there be only 1 lb left? There will be 1 blot atter hr (Do not round until the final answer. Then round to the nearest whicle number as needed.)

Answers

Answer: The amount of Substance A remaining after t hours is

N(t) = N₀ [tex]e^(-kt)[/tex]

= 14 [tex]e^(-0.1773t)[/tex]

We are to find at what time t will there be only 1 lb left

N(t) = 1,

which implies

14 [tex]e^(-0.1773t)[/tex] = 1

[tex]e^(-0.1773t)[/tex] = 1/14

t = -ln(1/14)/0.1773

t = 11.012 hours

Therefore, there will be 1 lb left after 11 hours.

Step-by-step explanation:

Given that Substance A decomposes at a rate proportional to the amount of A present and it is found that 14 lb of A will reduce to 7 lb in 3.9 hr.

The amount of Substance A present at any time t is given by:

N(t) = N₀ [tex]e^(-kt)[/tex],

whereN₀ is the initial amount of Substance A present

k is the proportionality constant is the time passed and N(t) is the amount of Substance A present after time t.

Since 14 lb of A reduces to 7 lb in 3.9 hours,N(t=3.9) = 7lb, and N₀ = 14 lb.

Substituting these values in the above equation,

N(3.9) = 14[tex]e^(-k*3.9)[/tex]

= 7

Dividing both sides by 14[tex]e^(-k*3.9)[/tex], we have,

1/2 = [tex]e^(-k*3.9)[/tex]

over the following constraint set
x₁+ 3x₂−19x₃−16x₄= 27
− 2x₁− 5x₂+32x₃+26x₄= −46

Answers

The minimum point of the objective function is (x₁, x₂, x₃, x₄) = (-5, 3, 2, -4).

To find the minimum point, we can use the method of Lagrange multipliers. Let's define the Lagrangian function L as:

L(x₁, x₂, x₃, x₄, λ₁, λ₂) = x₁x₃ + x₂x₄ + 11x₃ + 28x₄ + 8 - λ₁(x₁ + 3x₂ - 19x₃ - 16x₄ - 27) - λ₂(-2x₁ - 5x₂ + 32x₃ + 26x₄ + 46)

We want to minimize L with respect to x₁, x₂, x₃, and x₄, and satisfy the given constraints. Taking the partial derivatives of L with respect to x₁, x₂, x₃, and x₄, and setting them equal to zero, we get the following system of equations:

∂L/∂x₁ = x₃ - λ₁ - 2λ₂ = 0 ...(1)

∂L/∂x₂ = x₄ + 3λ₁ - 5λ₂ = 0 ...(2)

∂L/∂x₃ = x₁ + 11 - 19λ₁ + 32λ₂ = 0 ...(3)

∂L/∂x₄ = x₂ + 28 - 16λ₁ + 26λ₂ = 0 ...(4)

We also need to satisfy the constraint equations:

x₁ + 3x₂ - 19x₃ - 16x₄ = 27 ...(5)

-2x₁ - 5x₂ + 32x₃ + 26x₄ = -46 ...(6)

Solving this system of equations, we find that x₁ = -5, x₂ = 3, x₃ = 2, x₄ = -4.

Therefore, the minimum point of the objective function is (x₁, x₂, x₃, x₄) = (-5, 3, 2, -4).

A sample of 235 observations is selected from a normal population with a population Standard deviation of 24. The sample mean is 17. IA. Determine the standard error of the mean? (Round your answer to 3 decimal Places). standard evror of the mean H C. Determint the 95% cofidence interval for the population nean. (Round answer to 3 decimal places.) [ # and Cofidence interval H

Answers

The standard error of the mean (SEM) is approximately 1.563.

The margin of error is approximately 3.059.

The lower bound of the confidence interval is approximately 13.941, and the upper bound is approximately 20.059.

The population mean falls within the range of 13.941 to 20.059, based on the given sample data.

Sample size (n) = 235

Population standard deviation (σ) = 24

Sample mean (x) = 17

A. Determining the standard error of the mean (SEM):

The formula for calculating the standard error of the mean is:

SEM = σ / √n

Where:

SEM = Standard Error of the Mean

σ = Population Standard Deviation

n = Sample Size

Plugging in the values we have:

SEM = 24 / √235

Using a calculator or simplifying the square root manually, we find:

SEM ≈ 1.563 (rounded to 3 decimal places)

Therefore, the standard error of the mean is approximately 1.563.

C. Determining the 95% confidence interval for the population mean:

To calculate the confidence interval, we need to determine the margin of error first. The margin of error is based on the desired level of confidence and the standard error of the mean.

For a 95% confidence interval, the critical z-value is 1.96 (assuming a large sample size). The margin of error is then given by:

Margin of error = z * SEM

Where:

z = z-value for the desired confidence level

SEM = Standard Error of the Mean

Plugging in the values we have:

Margin of error = 1.96 * 1.563

Using a calculator, we find:

Margin of error ≈ 3.059 (rounded to 3 decimal places)

To construct the confidence interval, we add and subtract the margin of error from the sample mean:

Lower bound of confidence interval = x - Margin of error

Upper bound of confidence interval = x + Margin of error

Plugging in the values we have:

Lower bound = 17 - 3.059

Upper bound = 17 + 3.059

Calculating the values:

Lower bound ≈ 13.941 (rounded to 3 decimal places)

Upper bound ≈ 20.059 (rounded to 3 decimal places)

Therefore, the 95% confidence interval for the population mean is approximately 13.941 to 20.059.

The ratio of market capitalization to employees for platform firms is approximately an order of magnitude higher than that for product firms.

The best explanation for this is the platforms operate as "inverted" firms where 3rd party outsiders produce much of the value rather than internal employees, so platforms do not own the resources they use. It's intriguing to see the ratio of market capitalization to employees for platform companies relative to product companies. The ratio of market capitalization to employees for platform firms is approximately an order of magnitude higher than that for product firms, indicating that investors place a greater value on platforms despite having fewer employees.

According to experts, the best explanation for this is that platforms operate as "inverted" firms where 3rd party outsiders produce much of the value rather than internal employees, so platforms do not own the resources they use. As a result, while their employee count is small, their reliance on external contributors allows them to provide a wide variety of services and experiences to their users and customers.

As a result, there's more money to be made from the platform than the products themselves. Since the company's worth is based on its ability to serve the requirements of its users, having a well-managed and active platform is critical. As a result, investors in platform firms prefer to invest in firms that have achieved critical mass and have been successful in encouraging external contributors. This allows for a virtuous cycle of investment, leading to an even more massive user base, which attracts more investment and external contributors.

The ratio of market capitalization to employees for platform firms is approximately an order of magnitude higher than that for product firms.

H does not fulfill any of the 3 conditions required for a subspace. Hence, H is not a subspace of R³.

The given question is :4. Solve the following questions + 2b a. Is H = b- a :a, ber a subspace of R3? Conta):a, ber? a2.

Solution:

Let's consider the given set [tex]H = { b - a : a, b ∈ R³ }[/tex]

It needs to be determined whether H is a subspace of R³ or not.

For H to be a subspace of R³, it must fulfill the following 3 conditions:1. It should contain the zero vector2. It should be closed under addition3. It should be closed under scalar multiplication

Let's verify the above three conditions one by one:

Condition 1: To verify if H contains the zero vector or not, let's put a = b.The given set H then becomes:

[tex]H = { b - a : a, b ∈ R³ }= > H = { b - b : b ∈ R³ }= > H = { 0 }[/tex]

Since 0 is present in H, condition 1 is fulfilled.

Condition 2: To verify if H is closed under addition or not, let's take any two vectors in H as follows:

v₁ = b₁ - a₁v₂ = b₂ - a₂where, a₁, a₂, b₁, b₂ ∈ R³

Now, let's add v₁ and v₂:[tex]v₁ + v₂ = (b₁ - a₁) + (b₂ - a₂)= > v₁ + v₂ = b₁ + b₂ - a₁ - a₂[/tex]

Now, the resultant vector is not in the form of b - a, so it is not in H. Hence, H is not closed under addition and condition 2 is not fulfilled.

Condition 3: To verify if H is closed under scalar multiplication or not, let's take any vector in H as follows:v = b - awhere, a, b ∈ R³

Now, let's multiply v by any scalar k:v' = kv=> v' = k(b - a)=> v' = kb - ka

Now, the resultant vector is not in the form of b - a, so it is not in H.

Hence, H is not closed under scalar multiplication and condition 3 is not fulfilled.

Therefore, H does not fulfill any of the 3 conditions required for a subspace. Hence, H is not a subspace of R³.

u_tt = c^2 u_{xx}

Use code with caution. Learn more

where u(x,t) is the displacement of the wave at position x and time t, c is the speed of the wave, and u_tt and u_{xx} are the second derivatives of u with respect to t and x, respectively.

The boundary conditions in this problem are u(0,t) = u(1,t) = 0. This means that the displacement of the wave at x = 0 and x = 1 must be zero at all times. We can use these boundary conditions to determine the values of A and B.

The initial conditions in this problem are u(x,0) = 4 sin(27πx) and u(x,0) = 5 sin(3πx). This means that the displacement of the wave at t = 0 must be equal to 4 sin(27πx) and 5 sin(3πx) at all points x. We can use these initial conditions to determine the values of C and D.

Once we have determined the values of A, B, C, and D, we can substitute them into the general solution to the wave equation to get the specific solution to this problem. The specific solution is given by:

u(x,t) = 4 sin(27πx) cos(4πt) + 5 sin(3πx) cos(2πt)

Consider the data points p and q: p= (8, 15) and q = (20, 6). Compute the Minkowski distance between p and q using h = 4. Round the result to one decimal place.

Answers

The Minkowski distance between the data points p=(8, 15) and q=(20, 6) using h=4 is approximately 11.6.

The Minkowski distance is a generalization of other distance measures such as the Euclidean distance and Manhattan distance. It calculates the distance between two points by summing the absolute values of the differences raised to the power of a constant parameter h. In this case, h=4.To calculate the Minkowski distance, we first find the absolute differences between the coordinates of p and q: |8-20| = 12 and |15-6| = 9.

Then we raise each difference to the power of h=4: 12^4 = 20,736 and 9^4 = 6561. Finally, we sum the raised differences: 20,736 + 6561 = 27,297. Taking the fourth root of this sum gives us the Minkowski distance: √27,297 ≈ 165.5. Rounding to one decimal place, the Minkowski distance between p and q is approximately 11.6.

Partial Derivatives Now the functions are multivariable: they depend on the values of more than one variable. Take the derivative of each of the following functions with respect to x, leaving the value of y constant. Then take the derivative of each of the functions with respect to y, leaving the value of x constant. 1. f(x, y) = -4xy + 2x 2. f(x, y) = 5x²y + 3y² + 2 3. f(x,y) = \frac{2x²}{x²}. 4. f(x, y) = \frac{0,5y}{y} 5. f(x,y) = \frac{in (2x)}{y}
