Based on the given information, the estimated current stock price for Full Boat Manufacturing is $13.11. This is calculated using the discounted cash flow model, taking into account the projected future cash flows, growth rates, and required rate of return.

To calculate the current stock price, we need to estimate the free cash flows and discount them at the required rate of return.

First, we calculate the free cash flow to the firm (FCFF) for next year as follows

FCFF = Sales - Costs - Net Investment*(1-t)

= $115 million - $67 million - $12 million*(1-0.21)

= $31.02 million

Next, we calculate the expected growth rate in FCFF using the formula:

g = (FCFF Year 2 / FCFF Year 1) - 1

where FCFF Year 2 = FCFF Year 1 * (1 + g)

Using the given information, we get

g = (FCFF Year 2 / FCFF Year 1) - 1

= (FCFF Year 1 * (1 + 0.14) * (1 - 0.02) / FCFF Year 1) - 1

= 0.12

We can now use the Gordon growth model to estimate the current stock price

Current stock price = FCFF Year 1 * (1 + g) / (r - g)

where r is the required rate of return.

Substituting the values, we get

Current stock price = $31.02 million * (1 + 0.12) / (0.13 - 0.12)

= $72.13 million

Finally, we divide the current stock price by the number of shares outstanding to get the estimate of the current stock price per share:

Current stock price per share = $72.13 million / 5.5 million

= $13.11 per share

Therefore, the estimate of the current stock price is $13.11 per share.

The measure of the angle WXY is 152 degrees

From the question, we have the following parameters that can be used in our computation:

Using the above as a guide, we have the following:

m∠MYW = 104 - 90

m∠MYW = 14

The inscribed angle opposite to the same arc is half of the external angle

So, we have

mw = 2 * m∠MYW

mw = 2 * 14

mw = 28 degrees

Also, we have

my = 180 degrees

So, we have

Angle WXY = 180 - 28

Evaluate the difference

Angle WXY = 152

Hence, the measure of the angle is 152 degrees

Using the Law of Sines and Cosines, we get all possible values of ∠H are approximately 60.6° and 69.0°.

We can use the Law of Cosines to find the length of side GH

GH² = g² + h² - 2gh cos(G)

GH² = (9.3)² + (9.6)² - 2(9.3)(9.6)cos(109°)

GH ≈ 3.585 cm

Next, we can use the Law of Sines to find the measure of angle H

sin(H)/GH = sin(G)/HI

sin(H)/3.585 = sin(109°)/HI

sin(H) ≈ 3.585(sin 109°)/HI

H ≈ arcsin[3.585(sin 109°)/HI]

Since we do not know the length of side HI, we cannot determine the exact value of angle H. However, we can find the possible range of angle H by assuming that HI is the longest side of the triangle (making angle H the smallest) and the shortest side of the triangle (making angle H the largest).

If HI is the longest side, then H ≈ arcsin[3.585(sin 109°)/9.3] ≈ 60.6°

If HI is the shortest side, then H ≈ arcsin[3.585(sin 109°)/9.6] ≈ 69.0°

Therefore, the possible values of angle H are between approximately 60.6° and 69.0°.

The basal metabolic rate for a 180-kilogram lion is approximately 766.4 Calories per day.

The formula predicts that an 80-kilogram human would have a basal metabolic rate of approximately 1,313.9 Calories per day.

The basal metabolic rate is the amount of energy that an organism needs to carry out its basic physiological functions, such as breathing and circulating blood. In this case, Kielber's law is expressed as:

R = 73 [tex]\sqrt[4]{M^3}[/tex]

Let's use this function to find the basal metabolic rate for a 180-kilogram lion. To do this, we simply substitute M = 180 into the equation and solve for R:

R = 73 [tex]\sqrt[4]{180^3}[/tex]

R = 73 [tex]\sqrt[4]{5832}[/tex]

R ≈ 766.4

Now, let's find the formula's prediction for an 80-kilogram human. Again, we simply substitute M = 80 into the equation and solve for R:

Compared with an SRS of 900 8th-graders, the margin of error for a 95% confidence interval for mu is smaller when using an SRS of 1600 8th-graders.

To compare the margin of error for a 95% confidence interval for the population mean (mu) with a sample of 900 8th-graders versus 1600 8th-graders, we can follow these steps:
1. Identify the standard deviation (sigma) and sample sizes (n1 = 900 and n2 = 1600).
2. Calculate the standard error for each sample size:
SE1 = sigma / sqrt(n1) = 125 / sqrt(900) = 125 / 30
SE2 = sigma / sqrt(n2) = 125 / sqrt(1600) = 125 / 40

3. Determine the critical value (z-score) for a 95% confidence interval. In this case, it is 1.96 (you can find this value from a standard normal distribution table or using a calculator).
4. Calculate the margin of error for each sample size:
ME1 = z-score * SE1 = 1.96 * (125 / 30)
ME2 = z-score * SE2 = 1.96 * (125 / 40)
5. Compare the margin of errors:
ME1 is larger than ME2.

The probability of rolling any number other than 4 on a number cube with sides numbered 1, 2, 3, 4, 5, and 6 is 5/6, which can be written as a fraction in simplest form.

The complement of rolling a 4 on a number cube with sides numbered 1, 2, 3, 4, 5, and 6 is rolling any number other than 4, which includes rolling a 1, 2, 3, 5, or 6.

To find the probability of the complement, we need to add up the probabilities of rolling each of these numbers.

Since each number has an equal chance of being rolled, we can find the probability of rolling each number by dividing 1 by the total number of possible outcomes (which is 6, since there are six sides on the cube).

Then, we can add up the probabilities of rolling each of the five numbers in the complement:

P(rolling a 1, 2, 3, 5, or 6) = P(rolling a 1) + P(rolling a 2) + P(rolling a 3) + P(rolling a 5) + P(rolling a 6)

P(rolling any number other than 4) = 1 - P(rolling a 4)

P(rolling any number other than 4) = 1 - 1/6 = 5/6

Therefore, the probability of rolling any number other than 4 on a number cube with sides numbered 1, 2, 3, 4, 5, and 6 is 5/6, which can be written as a fraction in simplest form.

The construction steps for bisecting an angle are similar to those for bisecting a line segment as both involve using a compass and straightedge, but the former creates an angle with a specific degree measure while the latter divides a line segment into two equal parts.

The construction steps for constructing and bisecting an angle are similar to the steps for constructing and bisecting a line segment in that they both involve using a compass and straightedge to create geometric constructions.

However, the steps are different in that constructing and bisecting an angle involves creating an angle with a specific degree measure, whereas constructing and bisecting a line segment involves dividing a line segment into two equal parts.

To construct and bisect an angle, the compass is used to create congruent arcs on either side of the angle, and the straightedge is used to connect the intersections of those arcs to create the angle. To bisect a line segment, the compass is used to create arcs of equal length from the endpoints of the segment, and the straightedge is used to connect the intersection of those arcs to the midpoint of the segment.

By simplification Reema bought 5 boxes of pencils, which is a total of 60 pencils, in August.

Let x be the number of pencils Reema bought in August. According to the problem, she gave away 1/4 of the pencils, which means she kept 3/4 of the pencils. Then, she used 2/3 of what she had left, which means she used:

(2/3)(3/4)x = (1/2)x

So, if she used half of what she had left, she must have started with twice as many pencils. Therefore:

2x = total number of pencils she started with

And we know that she ended up with 3 pencils left, so:

2x - (1/4)(2x) - (1/2)x = 3

Simplifying this equation, we get:

(7/4)x = 3 + (1/2)x

Multiplying both sides by 4/7, we get:

x = (12/7)(3) = 36/7

Since Reema cannot buy a fractional number of pencils, we need to round up to the nearest whole number. Therefore, Reema bought 5 boxes of pencils, or a total of 60 pencils, in August.

Equation: g(x)=-5^(x-2)

Second Problem:

Transformation: Reflection across the y-axis, shift 4 units upward

Equation: 10^-x+4

Step-by-step explanation:

Imagine folding a piece of paper and using the x or y axis as the crease marks. By folding them and comparing them, we can find out whether it is either the x-axis, y-axis, or both-axis. Then, we move the graph, to match the position in the second picture.

As for equations, exponential functions have the parent function of y=b^(x+c)+h. By plugging in any points given, let's say (1,5), we can see that 5=b^1 and simplifying shows 5=b. Therefore, the function is y=5^x. Using that first equation, we transform it. If over the x-axis, convert y=b^x to y=-b^x. If over the y-axis, convert y=b^x to y=b^-x. For horizontal shift, if going rightward, it is x-c. If going leftward, it is x+c. For vertical shift, if going up, b^x+h. If going down, b^x-h.

So they are supplementary (their sum is 180 degrees).

We also know that angles c and d are opposite angles of the quadrilateral abcd, and they are given in the problem. Using the fact that angles on the same side of a chord are equal, we can say that angles a and d are equal, and angles b and c are equal.

Therefore, we can set up the following equation:

a + d = 180 (because they are supplementary)
d = 121
a = d (because they are opposite angles of the quadrilateral)
b = c (because they are opposite angles of the quadrilateral)
c + d = 180 (because they are supplementary)
c = 93

To estimate I = S." (+2) + dx using n = 4 subintervals and left endpoints, we need to divide the interval [2, 6] into 4 equal subintervals, each of width dx = (6-2)/4 = 1. Then, we can approximate the integral by adding up the areas of the rectangles whose heights are the function values at the left endpoints of each subinterval.

(a) Using left endpoints, the approximation of the integral is:

I ≈ sum from i=0 to 3 of f(2+i*dx)*dx
 = f(2)*dx + f(3)*dx + f(4)*dx + f(5)*dx
 = f(2)*1 + f(3)*1 + f(4)*1 + f(5)*1

(b) Using right endpoints, the approximation of the integral is:

I ≈ sum from i=1 to 4 of f(2+i*dx)*dx
 = f(3)*dx + f(4)*dx + f(5)*dx + f(6)*dx
 = f(3)*1 + f(4)*1 + f(5)*1 + f(6)*1

In both cases, we simply evaluate the function at the specified endpoints of each subinterval, multiply by the width of the subinterval, and sum up the results.

Note that the choice of left or right endpoints will affect the accuracy of the approximation, but in general, using more subintervals will lead to a more accurate result.
(a) Left Endpoints:

To estimate I using 4 subintervals and left endpoints, first divide the interval [0, 2] into 4 equal subintervals. Each subinterval has width Δx = (2 - 0) / 4 = 0.5. The left endpoints of these subintervals are x = 0, 0.5, 1, and 1.5. The integral estimate is:

I ≈ Δx[f(0) + f(0.5) + f(1) + f(1.5)]

Evaluate the function at these points, and then multiply the sum by Δx.

(b) Right Endpoints:

To estimate I using 4 subintervals and right endpoints, again divide the interval [0, 2] into 4 equal subintervals with width Δx = 0.5. The right endpoints of these subintervals are x = 0.5, 1, 1.5, and 2. The integral estimate is:

I ≈ Δx[f(0.5) + f(1) + f(1.5) + f(2)]

Evaluate the function at these points, and then multiply the sum by Δx.

14 = 2x

x = 7

The length of the side MJ is:

3(7) + 2 = 23

Now, the triangle MNJ is a right triangle thus using Pythagoras Theorem we have:

h² = a² + b²

23² = 16² + y²

529 = 256 + y²

273 = y²

y ≈ 16.5

Now, diagonals of kite are perpendicular thus,

2z - 8 = 90

2z = 98

z = 49

Hence, the value of z in the given figure is 49.
