Question 764672: The function h=-t^2+95 models the path of a ball thrown by a boy where h represents height, in feet, and t represents the time in seconds that the ball is in the air. Assuming the boy lives at sea level where h=0 ft., which is a likely place the boy could have been standing when he threw the ball?
A. His back yard
B. in an underground cave
C. On a latter
D. On a bridge

You can put this solution on YOUR website! The function h=-t^2+95 models the path of a ball thrown by a boy where h represents height, in feet, and t represents the time in seconds that the ball is in the air. Assuming the boy lives at sea level where h=0 ft., which is a likely place the boy could have been standing when he threw the ball?
A. His back yard
B. in an underground cave
C. On a latter
D. On a bridge
.
The equation:
h=-t^2+95
describes the height of the ball as a function of time (t).
When t is zero, we have:
h=-(0)^2+95
h = 95 feet
That is, before he threw the ball, the height is at 95 feet.
That is about the height of a bridge.
