Answer: 50 ft

Step-by-step explanation:

The correct function is h (t) = -16t^2+200t+50.

Hi, to answer this question we simply have to replace t = 0 in the function given:

h (t) = -16t^2+200t+50.

h (0) = - 16t^2+200t+50.

h (0) = 50

When the time is 0, the rocket is at the top of the building.

The rocket was launched from a 50 ft height.
