Answer:
Step-by-step explanation:
This is most easily solved with calculus, believe it or not. It is way more direct and to the point, with a whole lot less math!
The position function is given. The velocity function is the first derivative of the position, so if we find the velocity function and set it equal to 0, we can solve for the amount of time it takes for the rocket to reach its max height. Remember from physics that at the top of a parabolic path, the velocity is 0.
If:
, then the velocity function, the first derivative is:
v(t) = -32t + 112 and solve for t:
-112 = -32t so
t = 3.5 seconds. Now we know how long it takes to get to the max height, we just need to find out what the max height is.
Go back to the position function and sub in 3.5 for t to tell us that position of the rocket at 3.5 seconds, which translates to the max height:
and
s(3.5) = 206 feet. I imagine that your answer, if you had to choose one from the list, would be 200 feet, rounded a lot.

Part 1)
Part 2)
Step-by-step explanation:
<u><em>The correct question is</em></u>
Find the volume and the surface area of a rectangular prism. Bases are squares with sides that measure 27 inches. The height is 12 inches.
Part 1) Find the volume of the prism
The volume of the prism is equal to
where
B is the area of the base
h is the height of the prism
<em>Find the area of the base B</em>
---> the base is a square
we have
substitute
Part 2) Find the surface area of the prism
The surface area of the prism is equal to
where
B is the area of the base
P is the perimeter of the base
h is the height of the prism
<em>Find the perimeter of the base P</em>
<em></em><em></em>
substitute the values in the formula
