A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by th
Firlakuza [10]

Answer:

Time required to hit the ground is 7.9 s.

Step-by-step explanation:

The height of the rocket is given by

y =- 16 x^2 + 119 x + 57

For the time to hit the ground, put y = 0

-16x^2+119x+57=0\\\\16 x^2 - 119 x - 57 = 0 \\\\x = \frac{119\pm\sqrt{14161+3648}}{32}\\\\x = \frac{119\pm133.45}{32}\\\\t = - 0.45 s, 7.9 s

Time cannot be negative, so time to hit the ground is 7.9 s.
