1.
Height h = 240 feet
We insert it into formula.
240 = -16 t^{2} +128t
Now we solve this for t:
16 t^{2} -128t +240 = 0 /16  \\  t^{2}  - 8t +15 =0 \\ t_{1} = 5 t_{2} = 3

We have two answers as the rocket will pass this height on it's way up and down.

2.
Height h = 0 feet
We insert it into formula.
0=-16 t^{2} +76t + 2
Now we solve this for t:
16 t^{2} - 76t -2 = 0 /2 \\ 8t^{2} - 38t - 1 = 0 \\ t_{1} = 5 t_{2} = -1
We do not consider solution -1 as the time can not be negative. Our solution is 5s.

3.
Height at bottom of hill h = 0 feet
We insert it into formula.
v^{2} = 64 * 0 = 0 ft/s

Answer: B and D

Step-by-step explanation:

I see you picked the first one which is close but not right. This isn't right because you are adding the area of both rectangles together and in the first choice the + 7 should be 7y because y is the height which is why the 4th choice is correct and the second choice if you distribute you get 5y + 7y which is the same so that would be right as well.
