you're valuing horn of plenty mining, inc.'s, stock in order to compare its value to its market price. you believe that the company will pay total dividends of $1.45 in 2015 and $1.56 in 2016. you also believe the company's stock price will be $35.80 at the end of 2016. if the appropriate discount rate is 12 percent, what's the value of horn of plenty mining's stock? a. $39.22 b. $38.31 c. $36.87 d. $37.43
Answers
Step 1: Calculate the present value of each dividend payment.
PV(2015) = $1.45 / (1 + 0.12)^1 = $1.29
PV(2016) = $1.56 / (1 + 0.12)^2 = $1.22
Step 2: Calculate the present value of the expected stock price at the end of 2016.
PV(2016 stock price) = $35.80 / (1 + 0.12)^2 = $28.33
Step 3: Add up the present values of the dividend payments and stock price to get the total stock value.
Stock value = PV(2015) + PV(2016) + PV(2016 stock price) = $1.29 + $1.22 + $28.33 = $30.84
Therefore, the value of Horn of Plenty Mining's stock is $30.84, which means that the correct option is e) None of the above.

Mrs alvares rents skis and poles for 3 days what is the total cost of rental
Answers
The total cost of rents is $180.
In the given table,
The cost of skis per day = $48
The cost of pole per day = $12
Now since given that,
Alveres rents for 3 days
Therefore,
The cost of skis for 3 days = $48 x 3
= $144
The cost of pole for 3 days = $12 x 3
= $36
To find the total cost of rental,
Adding the cost of 3 days of skis and cost of 3 days of poles,
Hence,
Total cost of rents = $144 + $36
= $180

Felix needs to find x and y in the following system:

If he wants to use the elimination method to eliminate one of the variables, which is the most efficient way for him to do so?
A. Add Equation A and Equation B
B. Subtract Equation B from Equation A
C. Multiply Equation A by 5.
D. Divide Equation B by -1.
Answers
Answer:
A. Add Equation A and Equation B.
Step-by-step explanation:
When you add Equation A and Equation B, you'd get (when combining like terms)
(7y + 3y) + (-4x + 4x) = (5 + 25), which becomes 10y = 30
This show us that adding the equations allows us to cancel (eliminate) the x variable. Then we'd solve for y and later we'd solve for x by plugging in the value for y into either equation A or equation B.
What lump sum should be deposited in an account that will earn 9% compounded every 2 months, to grow to $100,000 in 32 years? Show your step process, when you are solving the problem.
Answers
Answer:
We should deposit approximately $14,408.92 in the account to grow to $100,000 in 32 years, assuming a 9% annual interest rate compounded every 2 months.
Step-by-step explanation:
To solve this problem, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
where:
A = the future value of the investment
P = the initial principal (the lump sum we need to deposit)
r = the annual interest rate (9% in this case)
n = the number of times the interest is compounded per year (since interest is compounded every 2 months, or 6 times per year, n = 6)
t = the number of years (32 years in this case)
We are given that we want the investment to grow to $100,000 in 32 years, so we can set A = $100,000 and solve for P:
$100,000 = P(1 + 0.09/6)^(6*32)
Simplifying the expression inside the parentheses:
$100,000 = P(1.015)^192
Dividing both sides by (1.015)^192:
P = $100,000 / (1.015)^192
Using a calculator:
P ≈ $14,408.92
Therefore, we should deposit approximately $14,408.92 in the account to grow to $100,000 in 32 years, assuming a 9% annual interest rate compounded every 2 months.
2. Kurt designs a square flower garden that has the same area as a rectangular one. The length of the rectangular
garden is 10 feet longer than the side of the square garden. The width of the rectangular garden is 5 feet shorter
than the side of the square. Find the side length of the rectangular garden.
low
Answers
The side length of the the rectangular garden are 20 feet by 5 feet.
Calculating the size of a Rectangular GardenLet
s = side length of the square garden
l = length of the rectangular garden
w = width of the rectangular garden
From the problem statement,
area of the square garden = area of the rectangular garden
Since the area of a square is just the side length squared, we can write:
s² = l * w
We also know that the length of the rectangular garden is 10 feet longer than the side of the square garden, and that the width of the rectangular garden is 5 feet shorter than the side of the square garden. We can express them as:
l = s + 10
w = s - 5
Now we can substitute these expressions for l and w into our first equation:
s² = (s + 10) * (s - 5)
Expanding the right-hand side, we get:
s² = s² + 5s - 50
0 = 5s - 50
5s = 50
Dividing both sides by 5, we get:
s = 10
Since the side length of the square garden is 10 feet.
We can use this to find the dimensions of the rectangular garden:
l = s + 10 = 10 + 10 = 20
w = s - 5 = 10 - 5 = 5
So the dimensions of the rectangular garden are 20 feet by 5 feet.

(1 Point) Recall That In Problem 3 Of The Reading Questions For Section 2.1, You Found That If F(X) = Ln(X), Then F'(2) = 1/2. Use This To Find A Formula For The Tangent Line To F(X) = Ln(X) At X = 2. Use this to find a formula for the tangent line to f(x) = ln(x) at x = 2. y=2
Answers
Answer:
y = (1/2)(x - 2) + ln(2)
Step-by-step explanation:
The formula for the tangent line to f(x) = ln(x) at x = 2 is given by the equation:
y = f'(2)(x - 2) + f(2)
Where f'(2) is the derivative of f(x) evaluated at x = 2, and f(2) is the value of f(x) evaluated at x = 2.
Given that f(x) = ln(x) and f'(2) = 1/2, we can substitute these values into the equation to get:
y = (1/2)(x - 2) + ln(2)
So the formula for the tangent line to f(x) = ln(x) at x = 2 is:
y = (1/2)(x - 2) + ln(2)

The numerical value of a function f(x) at x = a is f(a).
--------------------------------
The percentage of smokers in x years after 1970 is given by:
\(p + \frac{x}{2} = 40\)
Then
\(p(x) = 40 - \frac{x}{2}\)
--------------------------------
2010 is 2010 - 1970 = 40 years after 1970, thus the percentage is p(40).
\(p(40) = 40 - \frac{40}{2} = 40 - 20 = 20\)

a rocket is launched from a tower. the height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the maximum height reached by the rocket, to the nearest tenth of a foot.
y=-16x^2+254x+79
: )
Answers
Answer:
1018.4 feet
Step-by-step explanation:
The maximum height reached by the rocket can be found by using the formula for the vertex of a parabola.
The vertex of the parabola y = ax^2 + bx + c is given by (-b/2a, c - b^2/4a).
In this case, the equation is y = -16x^2 + 254x + 79.
The maximum height is reached at x = -b/2a = -254/(2*-16) = 7.9375 seconds.
Plugging this value into the equation gives y = -16(7.9375)^2 + 254(7.9375) + 79 = 1018.4 feet.
Therefore, the maximum height reached by the rocket is 1018.4 feet to the nearest tenth of a foot.

"Distance traveled is a function of time." In the context of motion or travel, the distance traveled is often dependent on the amount of time that has passed.
Distance is a fundamental concept in physics and mathematics that measures the extent or length between two points.
It represents the amount of ground covered or space traveled. When we say that distance is a function of various factors, it means that different variables or parameters can influence the distance traveled.
In the context of motion or travel, the distance traveled is often dependent on the amount of time that has passed.
The sentence "Distance traveled is a function of time" expresses this relationship, indicating that the distance traveled can be determined or calculated based on the value of time.
Thus, it implies that as time changes, the corresponding distance traveled also changes, establishing a functional relationship between the two variables.
