The income effect resulting from the change in the price of x1 is approximately 17.14. This means that, due to the price increase of x1, the consumer's purchasing power has decreased by 17.14 units.

To determine the income effect resulting from the change in the price of good x1 (from P1 to P1'), we need to calculate the difference in the consumer's purchasing power before and after the price change.

Calculate the consumer's original budget allocation:

Using the original prices P1 = 15, P2 = 30, and the original income I = 2513, we can substitute these values into the given equations for x1 and x2:

x1 = (21/7P1) = (21/7 * 15) = 45

x2 = (51/7P2) = (51/7 * 30) = 219

So, the original budget allocation is x1 = 45 and x2 = 219.

Calculate the new budget allocation:

With the new price of P1' = 65, we can substitute it into the equation for x1:

x1' = (21/7P1') = (21/7 * 65) = 195/7 ≈ 27.86

Since the price of x1 has changed, we need to recalculate the quantity of x2. However, we don't have enough information about the relationship between x1 and x2 to determine the exact new quantity of x2.

Calculate the difference in purchasing power:

To calculate the income effect, we need to compare the consumer's purchasing power before and after the price change. Since the price of x1 has increased, the consumer can afford to buy less of x1. The income effect measures the change in purchasing power as a result of the price change.

Difference in purchasing power = Original budget allocation of x1 - New budget allocation of x1

= x1 - x1'

= 45 - (195/7)

= (315 - 195)/7

= 120/7 ≈ 17.14

The income effect resulting from the change in the price of x1 is approximately 17.14. This means that, due to the price increase of x1, the consumer's purchasing power has decreased by 17.14 units.

To express the product of (5x - 2)(3x + 2) as a trinomial;

Note that a trinomial has its highest index power to the power of 3. Therefore to express the result as a trinomial (which already has its highest index power to the power of 2), you now multiply the result by x to the power of 1 (or simply x)

Answer:

2(a - 3). = 4

_______

3

Cross multiply.

2(a- 3) = 12

2a - 6 = 12

2a = 12 + 6

2a = 18

a = 18 ÷ 2

a = 9

Answer:

a = 9

Step-by-step explanation:

Given

\(\frac{2(a-3)}{3}\) = 4 ( multiply both sides by 3 to clear the fraction

2(a - 3) = 12 ( divide both sides by 2 )

a - 3 = 6 ( add 3 to both sides )

a = 9

As a check substitute a = 9 into the left side of the equation and if equal to the right side then it is the solution.

\(\frac{2(9-3)}{3}\) = \(\frac{2(6)}{3}\) = \(\frac{12}{3}\) = 4 = right side

Thus solution is a = 9

Answer:

Step-by-step explanation:

The domain of the vector-valued function \(r(t) = \sqrt{t+4i} + \sqrt{t-9j}\) is {t: t ≥ 9}.

In the given functiovector-valued n, we have \(\sqrt{t+4i} + \sqrt{t-9j}\). To determine the domain, we need to identify the values of t for which the function is defined.

In this case, both components of the function involve square roots. To ensure real-valued vectors, the expressions inside the square roots must be non-negative. Hence, we set both t + 4 ≥ 0 and t - 9 ≥ 0.

For the first inequality, t + 4 ≥ 0, we subtract 4 from both sides to obtain t ≥ -4.

For the second inequality, t - 9 ≥ 0, we add 9 to both sides to get t ≥ 9.

Combining the results, we find that the domain of the function is {t: t ≥ 9}. This means that the function is defined for all values of t greater than or equal to 9.

Therefore, the correct choice is OA: {t: t ≥ 9}.

The fair return for Castle Black Camping (CBC) is 20%.

This is calculated by subtracting the risk-free rate (2%) from the market's expected return (11%), and then multiplying the result by 2 (since CBC is twice as risky as the average stock).

To form a portfolio that is half Harlan County Safety Co. (HCSC) and half CBC, we need to calculate the portfolio's beta. This is done by multiplying each stock's beta by its weight in the portfolio, and then adding the results. In this case, the portfolio's beta would be 0.6 (1.2 x 0.5 + 2 x 0.5).

The fair return for the portfolio is then calculated by adding the risk-free rate to the product of the portfolio's beta and the market's expected return. This gives us a fair return of 16.4% for the HCSC and CBC portfolio.

The solution to the given initial value problem, obtained using Laplace transforms, is y(x) = 0. This means that the function y(x) is identically zero for all values of x.

To find the solution of the initial value problem using Laplace transforms for the equation d²y/dx² + 9y = 9sin(t)u(t - 3), where y(0) = y'(0) = 0, we can follow these steps:

Take the Laplace transform of the given differential equation.

Applying the Laplace transform to the equation d²y/dx² + 9y = 9sin(t)u(t - 3), we get:

s²Y(s) - sy(0) - y'(0) + 9Y(s) = 9 * (1/s² + 1/(s² + 1))

Since y(0) = 0 and y'(0) = 0, the Laplace transform simplifies to:

s²Y(s) + 9Y(s) = 9 * (1/s² + 1/(s² + 1))

Solve for Y(s).

Combining like terms, we have:

Y(s) * (s² + 9) = 9 * (1/s² + 1/(s² + 1))

Multiply through by (s² + 1)(s² + 9) to get rid of the denominators:

Y(s) * (s⁴ + 10s² + 9) = 9 * (s² + 1)

Simplifying further, we have:

Y(s) * (s⁴ + 10s² + 9) = 9s² + 9

Divide both sides by (s⁴ + 10s² + 9) to solve for Y(s):

Y(s) = (9s² + 9)/(s⁴ + 10s² + 9)

Partial fraction decomposition.

To proceed, we need to decompose the right side of the equation using partial fraction decomposition:

Y(s) = (9s² + 9)/(s⁴ + 10s² + 9) = A/(s² + 1) + B/(s² + 9)

Multiplying through by (s⁴ + 10s² + 9), we have:

9s² + 9 = A(s² + 9) + B(s² + 1)

Equating the coefficients of like powers of s, we get:

9 = 9A + B

0 = A + B

Solving these equations, we find:

A = 0

B = 0

Therefore, the decomposition becomes:

Y(s) = 0/(s² + 1) + 0/(s² + 9)

Inverse Laplace transform.

Taking the inverse Laplace transform of the decomposed terms, we find:

L^(-1){Y(s)} = L^(-1){0/(s² + 1)} + L^(-1){0/(s² + 9)}

The inverse Laplace transform of 0/(s² + 1) is 0.

The inverse Laplace transform of 0/(s² + 9) is 0.

Combining these terms, we have:

Y(x) = 0 + 0

Therefore, the solution to the initial value problem is:

y(x) = 0

Step-by-step explanation:

The answer is (d) 6 variables, 1 of which is categorical.

The given data set consists of 6 variables, indicating that there are six distinct pieces of information being recorded or measured. Among these variables, only one is categorized as categorical. Categorical variables are qualitative in nature and represent characteristics or categories rather than numerical values. Examples of categorical variables include gender, color, type, or any other non-numeric attribute.

By deductive reasoning, since there is only one categorical variable in the dataset, the remaining five variables are likely to be quantitative. Quantitative variables are numerical and represent measurable quantities, such as age, weight, temperature, or time.

Identifying the number of categorical variables in a dataset is crucial for understanding the nature of the information being collected. In this case, we can confidently conclude that the data set contains 6 variables, with 1 of them being categorical, while the other 5 variables are likely to be quantitative.

we need to integrate the function with respect to x.

The integral of y = 1.5 x^-2.5 is:

∫ 1.5 x^-2.5 dx = -3x^-1.5 + C

where C is the constant of integration.

To evaluate the definite integral from x = 8 to x = t, we plug in the upper and lower limits of integration and subtract the values:

Area = [-3t^-1.5 + C] - [-3(8)^-1.5 + C]

Simplifying this expression, we get:

Area = -3t^-1.5 + 3(8)^-1.5

Now we can find the area for t = 10 and t = 100:

(a) t = 10:

Area = -3(10)^-1.5 + 3(8)^-1.5

Area ≈ 0.2455

(b) t = 100:

Area = -3(100)^-1.5 + 3(8)^-1.5

Area ≈ 0.0816

To find the total area under the curve for x ≤ 8, we need to integrate the function from 0 to 8:

∫ 1.5 x^-2.5 dx = -3x^-1.5 + C

Area = [-3(8)^-1.5 + C] - [-3(0)^-1.5 + C]

Profitability index is 1.387. Thus, the correct option is (c) 1.387.

The formula for calculating the profitability index is:

P.I = PV of Future Cash Flows / Initial Investment

Where,

P.I is the profitability index

PV is the present value of future cash flows

The initial investment in the project is $30 million. The cash flow at the end of the first year is $2.85 million.

The present value of cash flows can be calculated using the formula:

PV = CF / (1 + r)ⁿ

Where,

PV is the present value of cash flows

CF is the cash flow in the given period

r is the discount rate

n is the number of periods

For the first-year cash flow, n = 1, CF = $2.85 million, and r = 11%.

Substituting the values, we get:

PV = 2.85 / (1 + 0.11)¹ = $2.56 million

To calculate the present value of all future cash flows, we can use the formula:

PV = CF / (r - g)

Where,

PV is the present value of cash flows

CF is the cash flow in the given period

r is the discount rate

g is the constant growth rate

For the subsequent years, CF = $2.85 million, r = 11%, and g = 3.85%.

Substituting the values, we get:

PV = 2.85 / (0.11 - 0.0385) = $39.90 million

The total present value of cash flows is the sum of the present value of the first-year cash flow and the present value of all future cash flows.

PV of future cash flows = $39.90 million + $2.56 million = $42.46 million

Profitability index (P.I) = PV of future cash flows / Initial investment

= 42.46 / 30

= 1.387
