21.20ft^3 - I think
Explanation
To get the area of a 2d object, you would need to do (1.5•1.5)•3.14
So (1.5 • 1.5) =2.25
2.25•3.14 = 7.065
Now that you have the base, you need to multiply it by the height.
7.065 • 3 = 21.195 ≈ 21.20ft^3

The function which best models the amount of rent she will have to pay in each future year is y = 450(1.15)^x
<h3>How to write a function</h3>
- First year rent = $450
- Percentage increase per year = 15%
let
y = total rent paid each subsequent year
x = number of years
The function:
y = 450(1.15)^x
If x = third year
y = 450(1.15)^x
= 450(1.15)^3
= 450(1.520875)
= $684.39375
Given options:
A) y = 0.15x + 450
B) y- 450x + 0.15
C) y = 450(1.15)^x
D) y = 450(0.15)^x

Answer:
The speed of the wave at the given wavelength and frequency is 60 m/s.
The given parameters;
wavelength of the wave, λ = 0.5 m
frequency of the wave, f = 120 Hz
The speed of the wave is calculated by applying general wave equation as shown below;
v = fλ
where;
v is the speed of the wave
v = 120 x 0.5
v = 60 m/s
Thus, the speed of the wave at the given wavelength and frequency is 60 m/s.
Assuming your retirement is more than 2 years away, and that your car purchase is not before the end of the year, the shortest-term goal of those listed is ...

As a teenager, "short term" may be a matter of a week or two. As a middle-aged adult, both your life-lived and life-expectancy are somwhat longer, so "short-term" can be somewhat longer as well. In old age and failing health, "short-term" may again be a matter of a few weeks at most. Such concepts are tempered by perspective.
The answer is in the box. You do not need to write the y but that just helped me do the steps to get the answer
