The required return rate is 12.5%. The value of the stock is calculated by discounting the future dividends and the price target back to the present value that is $36.0153

To compute the value of the stock, we can use the formula for the dividend discount model:

Value of Stock = Dividend / \((1 + Required Return Rate)^n\) + Dividend / \((1 + Required Return Rate)^{(n+1)}\) + Price Target / \((1 + Required Return Rate)^{(n+2)}\)

In this case, the dividends are $2.55 and $2.70, the required return rate is 12.5%, and the price target is $40. The dividends are discounted back to the present value using the required return rate, and the price target is discounted back two years. By plugging in the values into the formula and calculating, we can find the value of the stock.

Using the given values, the value of the stock with a required return of 12.5% is calculated as follows:

Value of Stock = $2.55 /\((1 + 0.125)^1\) + $2.70 / \((1 + 0.125)^2\) + $40 /\((1 + 0.125)^2\)

Value of Stock ≈ $36.0153

Without the specific function form of S(t) and the values of C1 and C2, we cannot determine the numerical value of the integral.

To find the numerical value of the given integral:

∫(S(t + 2) - 28(4t)) dt

We need to know the function S(t) in order to evaluate the integral. The variable S(t) represents a function that is missing from the given expression. Without knowing the specific form of S(t), we cannot determine the numerical value of the integral.

However, if we assume S(t) to be a constant, let's say S, the integral simplifies to:

∫(S(t + 2) - 28(4t)) dt = S∫(t + 2) dt - 28∫(4t) dt

Applying the power rule for integration, we have:

∫(t + 2) dt = (1/2)t^2 + 2t + C1

∫(4t) dt = 2t^2 + C2

Substituting these results back into the integral:

S∫(t + 2) dt - 28∫(4t) dt = S((1/2)t^2 + 2t + C1) - 28(2t^2 + C2)

We can simplify further by multiplying S through the terms:

(S/2)t^2 + 2St + SC1 - 56t^2 - 28C2

Christina finished 5/8 of her dinner.

Did she finish more than 1/2 of her dinner?

Explain.​

Solution

Yes, she finished more than 1/2 of her dinner, because

5/ 8 = 0.625 is greater than 1/ 2 = 0. 5

More Explanation

5/ 8 in decimal = 0 . 625

1/ 2 in decimal = 0 . 5

Comparing the two: 0.625 ( 5/ 8 ) is greater than 0. 5 ( 1/ 2 )

The distance from point A to point C and the bearing from point A to point C is 229.5 miles.

Given that:

AB = 370 miles

angle A = 24 degrees

BC = 240 miles

angle B = 37 degrees 

To determine the distance from point A to C, we can use the cosine law since we are given two angles and two sides of a regular triangle. 

The angle opposite side AC is angle B which is equal to 37 degrees. 

(AC)^2 =(AB)^2 + (BC)^2 - 2(AB)(BC)cos(B)

Now we have to solve for AC:

(AC)^2 =(370)^2 + (240)^2 - 2(370)(240)cos(37) 

AC = 229.48 miles.

Hence the answer is, the distance from point A to point C and the bearing from point A to point C is 229.5 miles.

Answer:

\(a_1 = -11\\\\a_n = a_{(n - 1)} + 22\)

Step-by-step explanation:

An arithmetic sequence is generally given as:

f(n) = a + (n - 1)d

where a = first term and f(n) = nth term, d = common difference

The explicit formula given is:

f(n) = 11 + 22(n - 1)

The recursive formula is made of two statements, the first term and the formula showing how successive terms are related.

Mathematically, it is given as:

\(a_1 = a\\\\a_n = a_{(n - 1)} + d\)

Therefore, the recursive formula is:

\(a_1 = -11\\\\a_n = a_{(n - 1)} + 22\)

Answer:

1152 in ^ 3

Step-by-step explanation:

We know that the width is:

w = 4 in

They also tell us that the length is three times the width, therefore:

l = 3 * w

l = 3 * 4 = 12

l = 12 in

and as for the height, they tell us that it is twice the length, so:

h = 2 * l

h = 2 * 12 = 24

h = 24 in

now the volume is w * l * h, replacing:

v = 4 * 12 * 24

v = 1152

volume equals 1152 in ^ 3

The linear regression model can be extended to accommodate certain forms of non-linear relationships between the response and predictor(s).  Polynomial regression is one specific method for incorporating non-linear associations within the linear regression framework.

It involves understanding the flexibility of the linear regression model and the techniques available to address non-linear relationships. While the linear regression model assumes a linear relationship between the response variable and predictors, it can still be useful in accommodating certain types of non-linear relationships.

By applying appropriate transformations to the predictor variables, such as taking their squares, logarithms, or other non-linear functions, we can introduce non-linear associations into the linear regression model. This allows the model to capture curvature or other non-linear patterns in the data.

Polynomial regression is a specific approach to incorporating non-linear relationships within the linear regression framework. It involves adding polynomial terms of the predictor variables to the model, such as squared or cubed terms. By including these polynomial terms, the model can account for non-linear relationships and capture more complex patterns.

It's important to note that while linear regression can be extended to accommodate some non-linear relationships, there may be cases where more advanced non-linear regression techniques or alternative models are necessary to adequately capture complex non-linear associations. Nonetheless, the inclusion of transformed predictor variables and the use of polynomial regression are valuable approaches to address non-linear relationships within the linear regression framework.

Diego is applying the elimination method to solve the system and it is proved that his work is correct, that x = 1 and y = 2.

The elimination method is a technique used to solve linear equations. When using this method, we either add or subtract the equations to result in one variable equation.

In Diego's work, he added the two equations to eliminate the variable x and get the value of the variable y. As he knew the value of y, he applied this value to the equation to get the value of variable x.

To decide whether his work is correct, we can test it by applying the value of x and y to the equation:

4x + 3y = 10

4.1 + 3.2 = 10

4 + 6 = 10 ⇒ correct

-4x + 5y = 6

VR headsets does the store need to sell to break even is 64 (option B).

To find the number of VR headsets the store needs to sell to break even, we need to find the value of x that makes the cost function equal to the revenue function.

The cost function is given by c(x) = 28.15x + 355, and the revenue function is given by r(x) = 33.75x.

To find the value of x that makes the cost function equal to the revenue function, we can set the cost function equal to the revenue function and solve for x: 28.15x + 355 = 33.75x

5.6x = -355

x = -63

Since the number of VR headsets cannot be negative, the store needs to sell at least 64 VR headsets to break even.

Therefore, the number of VR headsets does the store need to sell to break even is 64 (option B).

The correct formula that defines an arithmetic sequence is option d) tn = 5n + 14.

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms remains constant. In other words, each term can be obtained by adding a fixed value (the common difference) to the previous term.

In option a) tn = 5 + 14, the term does not depend on the value of n and does not exhibit a constant difference between terms. Therefore, it does not represent an arithmetic sequence.

Option b) tn = 5n² + 14 represents a quadratic sequence, where the difference between consecutive terms increases with each term. It does not represent an arithmetic sequence.

Option c) tn = 5n(n+14) represents a sequence with a varying difference, as it depends on the value of n. It does not represent an arithmetic sequence.

Option d) tn = 5n + 14 represents an arithmetic sequence, where each term is obtained by adding a constant value of 5 to the previous term. The common difference between consecutive terms is 5, making it the correct formula for an arithmetic sequence.

The required manager has 12 fifty-dollar bills as of the given condition.

Let's denote the number of twenty-dollar bills as "x" and the number of fifty-dollar bills as "y".

We know that the convention manager has a total of 48 bills, so:
x + y = 48

We also know that the total amount of money she has is $1320, which can be expressed as:
20x + 50y = 1320

To solve for "y", we can rearrange the first equation to get:
y = 48 - x

Then substitute this expression for "y" in the second equation:

20x + 50(48 - x) = 1320

Expanding the expression and simplifying:
20x + 2400 - 50x = 1320
-30x = -1080
x = 36

So the manager has 36 twenty-dollar bills. To find the number of fifty-dollar bills, we can use the first equation:

x + y = 48

36 + y = 48

y = 12

Therefore, the manager has 12 fifty-dollar bills.
