Answer: 
Step-by-step explanation:
We are given the following formula, used to calculate the value of an used car according to the years after the car was originally bought:
Where 
is the price of the car when it was bought new, and 
is the number of years the car was used.
Solving the formula with the given data:
This is the value of the car according to the formula.
However, this value can be approximated to:
This question would actually go under physics
Assuming that the model rocket goes straight up into the air and not at an angle, you can calculate for the maximum height by finding how long it takes for the velocity of the rocket to reach 0.
This can be calculated using the equation
t = (v sinx) /g
where t=time, v=velocity at zero seconds, x=angle of launch, g=gravity
Since we are assuming that the rocket flies straight up, the angle would be 90º, so sinx would be equal to 1.
That reduces are equation to
t = v / g
g=9.81 m/s^-2
So we need to convert gravity to feet/second^-2 and divide 160 by g, 160 being the initial velocity.
g=9.81 m/s^-2 = <span>32.2 ft/s^-2
160/32.2 ≈ 4.97 seconds

Hi! Your answer should be, 1,960.89
Hope this helps you!
