The area of the base of the cylinder is 78.54 ft² and height of the cylinder is 6.31 ft.
To find the area of the base of the cylinder, we can use the formula:
A = πr²
Substituting the given value of radius, we get:
A = π(5 ft)²
A = 78.54 ft²
Therefore, the area of the base of the cylinder is 78.54 ft².
b. To find the height of the cylinder, we can use the formula for the volume of a cylinder:
V = πr²h
Substituting the given values of volume and radius, we get:
157.08 ft³ = π(5 ft)²h
Simplifying, we get:
h = 157.08 ft³ / (π(5 ft)²)
h = 6.31 ft
Therefore, the height of the cylinder is approximately 6.31 ft.

a certain forest covers an area of 1700km^(2). Suppose that each year this area descreases by 7.5%. What will the area be after 11 years?
round your answer to the nearest square kilometer.
The area of the forest after 11 years will be 298 km².
To calculate the area of the forest after 11 years, we need to decrease the initial area of 1700 km² by 7.5% each year for 11 years.
First, let's calculate the decrease in area for one year:
Decrease in area for one year = 7.5% of 1700 km²
7.5% of 1700 km² = (7.5/100) × 1700 km²
= 127.5 km²
Now, we can calculate the total decrease in area over 11 years:
Total decrease in area over 11 years = 11 × 127.5 km² = 1402.5 km²
Finally, we can subtract the total decrease in area from the initial area to get the area of the forest after 11 years;
Area of the forest after 11 years = Initial area - Total decrease in area
= 1700 km² - 1402.5 km²
= 297.5 km²
Therefore, Rounding to the nearest square kilometer, the area of the forest after 11 years will be approximately 298 km².

A. -3 B.0. C.8. D. Undefined
The line is a vertical line, then the correct option is D, the slope is undefined.
How to find the slope of the line?A general linear equation can be written as:
y = a*x + b
Where a is the slope, b is the y-intercept, and x is the variable.
If the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope of that line is given by the formula:
a = (y₂ - y₁)/(x₂ - x₁)
Here we know that the two points are (2, -4) and (2, 4)
Replacing that we would have a problem, that is because we have the same x-value in both points.
Then we have a vertical line at x = 2.

Find the total cost for the month in dollars. The federal tax is 3%. Use the figure below.
Monthly phone service plan is $52.00. Four lines and 3,487 minutes are used.
Answer:
The total cost per month is $190.76 to the nearest cent.
Step-by-step explanation:
From the given table, the monthly service plan costing $52.00 is:
Monthly Service Plan = $52.00Number of included minutes per month = 2,000 minutesCost per additional line per month = $21.99Overage per minute rate = $0.06The base calling plan includes two lines.
Therefore, for 4 lines, we will need to pay for 2 additional lines per month:
⇒ $21.99 × 2 = $43.98 per month
If 3,487 minutes are used per month, then the overage of minutes is:
⇒ 3487 - 2000 = 1487 minutes per month
As the overage rate is $0.06 per minute, then the cost of the additional minutes is:
⇒ 1487 × $0.06 = $89.22 per month
Therefore, the total cost per month before tax is:
⇒ $52.00 + $43.98 + $89.22 = $185.20
To apply the federal tax of 3%, multiply the total cost by 1.03:
⇒ $185.20 × 1.03 = $190.756 = $190.76 (nearest cent)
Therefore, the total cost per month is $190.76 to the nearest cent.
A bushel of apples costs $15.00 in the U.S. The same apples cost 1,600 yen in Japan. If the exchange rate is 80 yen per dollar, what is the real exchange rate? Is there a possibility for arbitrage? Explain and defend your answer.
The real exchange rate is 0.75.
It is not possible to make a profit by buying apples in one country and selling them in another.
We have,
To find the real exchange rate, we need to compare the price of apples in the two countries in terms of their respective currencies.
In the U.S., a bushel of apples costs $15.00.
In Japan, the same apples cost 1,600 yen.
Using the exchange rate of 80 yen per dollar, we can convert the cost in yen to dollars:
1,600 yen / 80 yen per dollar
= $20.00
So, the price of a bushel of apples in Japan is equivalent to $20.00 in the U.S.
The real exchange rate is the ratio of the prices of the same goods in two different countries, taking into account the exchange rate.
In this case, the real exchange rate is:
Real exchange rate = Price in U.S. / Price in Japan
= $15.00 / $20.00
= 0.75
This means that it takes 0.75 U.S. dollars to buy the same goods in Japan which would cost 1 Japanese yen.
To determine if there is an arbitrage opportunity, we need to compare the real exchange rate with the actual exchange rate.
If the real exchange rate is greater than the actual exchange rate, there is an arbitrage opportunity for someone to buy the good in one country and sell it in another country for a profit.
However, if the real exchange rate is less than the actual exchange rate, there is no arbitrage opportunity.
In this case,
The real exchange rate is 0.75, while the actual exchange rate is 80 yen per dollar, or 0.0125.
Since the real exchange rate is less than the actual exchange rate, there is no arbitrage opportunity.
Therefore,
The real exchange rate is 0.75.

Find the probability of getting two numbers whose sum is greater than 9. Group of answer choices
The probability of getting two numbers whose sum is greater than 9 = 5/36
We know that the probability is nothing but the number of favourable outcomes divided by the total number of outcomes.
Here, a single die is rolled twice.
and we get the set of 36 equally likely outcomes.
so, the total number of outcomes n(S) = 36
Let us assume that event A: getting two numbers whose sum is greater than 9
A = {(4, 6), (5,5), (5, 6), (6, 4), (6, 5)}
n(A) = 5
Using above formula of probability,

We are given that;
The four equations to match from
Now,
Using the slope-intercept form, we can plug in m = 3/2 and b = -8:
y = (3/2)x - 8
This equation matches with y = 3/2x - 5 if we multiply both sides by 2:
2y = 3x - 16
Therefore, the correct equation is 2y - x = -16.
A line that contains the points (0,-2) and (4,0)
m = (0 - (-2)) / (4 - 0) m = 2 / 4 m = 1/2
Then we can plug in m = 1/2 and any of the given points to find b. For example, using (0, -2), we have:
-2 = (1/2)(0) + b -2 = b
Therefore, the equation is:
y = (1/2)x - 2
This equation matches with -5x - 3y = -12 if we multiply both sides by -6:
6y = -3x + 12
Therefore, the correct equation is -5x - 3y = -12.
A line that contains the y-intercept (0-2) and the slope of -3/4
Using the slope-intercept form, we can plug in m = -3/4 and b = -2:

y ≤ ²/₃x - 4
How to interpret the Inequality Graph?An inequality can be represented graphically as a region on one side of a line. Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.
The formula for the equation of a line in slope intercept form is:
y = mx + c
where:
m is slope
c is y-intercept
The first inequality is the one with the dashed line and a y-intercept of 4 and so since shaded below line, we will use the symbol <.
The slope from two coordinates on the line (0, 4) and (4, 0) is:
(0 - 4)/(4 - 0) = -1
Thus, inequality is:
y < -x + 4
The first inequality is the one with the solid line and a y-intercept of -4 and so since shaded below line, we will use the symbol ≤.

The given statement "there is some k∈I such that [tex]D_{i}[/tex]⊆[tex]D_{k}[/tex] and [tex]D_{j}[/tex]⊆[tex]D_{k}[/tex]means that there is a set [tex]D_{k}[/tex] in a collection of sets I that contains all the elements of both sets [tex]D_{i}[/tex] and [tex]D_{j}[/tex].
For example, let's say we have a collection of sets I that includes sets A, B, C, D, E, and F. If we have two sets [tex]D_{i}[/tex] and [tex]D_{j}[/tex], where [tex]D_{i}[/tex] is the set of all even numbers, and [tex]D_{j}[/tex] is the set of all positive integers less than or equal to 10, then we can say that there exists a set [tex]D_{k}[/tex] in I that contains both [tex]D_{i}[/tex]and [tex]D_{j}[/tex] as subsets.
