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 gi
ven equation. Using this equation, find the time that rocket will hit the ground, to the nearest 100th of second. Y=-16x^2+157x+104
1 answer:
The time that rocket will hit the ground, to the nearest 100th of second is 10.43 seconds
Given the equation representing the height reached by a rocket as:

The rocket will hit the ground when y = 0. Substituting y = 0 into the expression to get x;

On factorizing:
x = 10.43 seconds
Hence the time that rocket will hit the ground, to the nearest 100th of second is 10.43 seconds

The answer would be 8 ^-5
Answer:
about 2 minutes
Step-by-step explanation:
first lets make everything in the same term
so 2.5 =2 1/2
then divide 5 5/16 by 2 1/2
or 85/16 divided by 5/2
you get 2 1/8
so you have about 2 minutes before the timer runs out
C = 64
73 + 43 = 116
180 - 116 = 64
