Ответ:
Maximum height of the rocket = 1194.39 feet.
Step-by-step explanation:
The equation that shows the height of the rocket, y in feet, is related to the time after launch, x in seconds is as follows :
...(1)
We need to find the maximum height reached by rocket. For maximum height,
Put x = 8.15 s in equation (1).
So, the maximum height of the rocket is 1194.39 feet.
