The firm should accept the project with an Internal Rate of Return (IRR) of 13%, as it is greater than their WACC of 8.5%.

To find the Weighted Average Cost of Capital (WACC) for the firm, we need to calculate the cost of debt, cost of preferred stock, and cost of equity:

Cost of Debt: 8% coupon bond / $1100 price = 7.2727% cost of debt

Cost of Preferred Stock: $5 dividend / $50 price = 10% cost of preferred stock

Cost of Equity: Risk-free rate + (Beta * Market risk premium) = 4% + (1.5 * 8%) = 14% cost of equity

WACC: (2 Mil * 7.2727%) + (4 Mil * 10%) + (6 Mil * 14%) / (2 Mil + 4 Mil + 6 Mil) = 8.5% WACC

The firm should accept the project with an Internal Rate of Return (IRR) of 13%, as it is greater than their WACC of 8.5%.

The mean selling price of new homes was $114,000. The population standard deviation was $5,000. A random sample of 100 new home sales was taken without doing the calculations, ranges the sample mean selling price is most likely to lie between C) $113,000 - $115,000.

The sample mean selling price is most likely to lie in the range of $113,000 to $115,000 because this range is within one standard deviation (i.e., $5,000) of the population mean of $114,000, and therefore it contains approximately 68% of the sample mean values. The other ranges are outside one standard deviation from the mean, and therefore, the probability of the sample mean being in those ranges is lower. However, it is important to note that the actual sample mean could fall outside this range as it is still subject to random variation.

The zeros of the polynomial function f(x) = -8(x-1)^(3)(x+5)^(2)x^(4) are x = 1, x = -5, and x = 0. The smallest zero is x = -5 with multiplicity 2.

To find the zeros of the polynomial function f(x) = -8(x-1)^(3)(x+5)^(2)x^(4), we need to set the function equal to zero and solve for x:

0 = -8(x-1)^(3)(x+5)^(2)x^(4)

This equation will be true when any of the factors on the right-hand side are equal to zero. Therefore, we can find the zeros by setting each factor equal to zero and solving for x:

x-1 = 0 -> x = 1
x+5 = 0 -> x = -5
x^(4) = 0 -> x = 0

So, the zeros of the polynomial function are x = 1, x = -5, and x = 0.

The smallest zero is x = -5 with multiplicity 2, since it is the smallest value of x and the factor (x+5)^(2) has an exponent of 2.

The height of the ball is represented by the equation -1(-6x^(2)+4x+2), where x is time in seconds.

We can rewrite this equation by distributing the -1 and simplifying.

First, we distribute the -1 to each term inside the parentheses:
-1(-6x^(2)+4x+2) = 6x^(2) - 4x - 2

Now, we can simplify by combining like terms:
6x^(2) - 4x - 2 = 6x^(2) - 4x - 2

Therefore, the rewritten equation for the height of the ball is:
h = 6x^(2) - 4x - 2

This equation shows the relationship between the height of the ball (h) and the time in seconds (x). As time increases, the height of the ball changes according to the equation.

c) Amortization per year = $14000 per year.

Amortisation of intangible assets : If any intangible assets are purchase and this will be amortized over the useful life of the assets and this will deduct the value of the intangible assets over the year completed. Now, we prepare a journal entry to record the expense:

a) A patent is a legal right granted to an individual or company to reproduce, use or sell an invention without interference from others.. A patent with 10-year remaining legal life was purchased for $350,000. Since the patent will be worthless after 8 years, the life will be considered to be 8 years. Amortization per year = $350000/8

= $43750 per year.

Amortization expense A/C.. Dr $43750 ( debit )

To Patents A/C $43750 ( credit)

b) Cost of the patent to date consisted in legal fee for handling the patent application = $52,300

Because the patent has commercial value during its remaining statutory life of 10 years. Only the original cost of patent will be amortized hence

Amortization per year = $52300/10

= $5230 per year

Amortization expense $5230 (debit)

Patents $5230 ( credit)

C) Since the additional cost will be incurred after 5 years and hence renewal is conditional , original life and cost will be considered.

The final solution to the inequality y>=-(7)/(6)x is the shaded region on the graph.

To solve the inequality y>=-(7)/(6)x, we will first graph the boundary line and then shade the appropriate region.

1. Begin by graphing the boundary line y=-(7)/(6)x. This line has a slope of -(7)/(6) and passes through the origin (0,0).

2. Since the inequality includes the "greater than or equal to" symbol (>=), the boundary line should be solid to indicate that points on the line are included in the solution.

3. Next, we need to determine which region to shade. To do this, we can choose a test point that is not on the boundary line. A common test point is (0,1), which is above the boundary line.

4. Substitute the coordinates of the test point into the inequality to see if it is true or false: 1>=-(7)/(6)(0)

5. Since the inequality is true, the region that includes the test point is the solution. This means we should shade the region above the boundary line.

6. The final graph should have a solid boundary line with the region above it shaded.

The solution to the inequality y>=-(7)/(6)x is the shaded region on the graph.

airplane A

To compare the rate of speed of Airplane A and Airplane B, we need to calculate the speed of Airplane B first.

The formula to calculate distance is:

distance = rate x time

For Airplane A, we know:

distance = 1662 miles

time = 6 hours

So, we can rearrange the formula to solve for the rate:

rate = distance / time = 1662 / 6 = 277 miles per hour

For Airplane B, we know:

y = 922/3

x = rate of speed over 6 hours

We can use the formula to solve for x:

distance = rate x time

922/3 = x * 6

x = (922/3) / 6 = 153.67 miles per hour

Comparing the rates of the two airplanes, we can see that Airplane A traveled at a faster rate with 277 miles per hour compared to Airplane B's rate of 153.67 miles per hour. Therefore, Airplane A traveled at a faster rate.

The probability of landing on a 6 is 1/6. The probability of rolling a 7 is zero.

The simple definition of probability is the likelihood that something will occur. We can discuss the probabilities of different outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics refers to the study of events subject to probability.

If you roll a fair number cube, The probability of landing on a 6 is 1/6.

As, all the possible outcome is 6 and favourable outcome is 1 (6), Probability = 1/6 or 16.66%

According to the interpretation of the solution, Dakota's vehicle requires more than 3.6 gallons of fuel to travel the 117 miles to his brother's home.

Dakota will use x gallons of gas to travel 117 miles to his brother's home.

The following inequalities can be used to determine how many gallons of fuel Dakota requires the most:

x ≥ 117/32.5

According to this inequality, x must be more than or equal to 117 miles, which is the required driving distance for Dakota, divided by 32.5 miles per gallon, the maximum fuel efficiency for his vehicle.

After finding x, we obtain:

x ≥ 3.6

A simplified way to write an expression is to use the expression in standard form. It entails expressing the expression in terms of its highest exponent, variables, and numerical coefficients. The use of standard form is intended to simplify the reading and comprehension of an expression. As opposed to writing an expression as, [tex]3x^2 + 4x +[/tex]7, it can be written in standard form as [tex]3x^2 + 4x + 7[/tex].

The two functions, f(x) and g(x), can be combined to form a single equation that expresses the length of the top surface of the rectangular boxes, which leads to the derivation of this expression.

The top surface's area is represented by the function f(x), which has the following form: [tex]f(x) = 66x^2 + 17x + 1[/tex]. With the formula g(x) = 6x + 1, the function g(x) denotes the width of the top surface. These two functions are combined to give us [tex]h(x) = 6x + 66x^2 + 17[/tex]. As a result, this expression describes how long the top surface of the rectangular boxes is.
