The function h = -t2 + 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 this ball?
A. his backyard

B. an underground cave

C. a ladder

Take a trip down memory lane :D

anonymous · Answer

Let $t=0$ to see where the ball is when he threw it.

shamil98 · Answer

The given is h = -t^2 + 95
he lives at sea level so h = 0

anonymous · Answer

No, I'm saying find $h(0$.  Since $t=0$ when he threw it.

shamil98 · Answer

The ball is in the air for t seconds as well.

anonymous · Answer

Baiscaly $$
h(0) = (0)^2+95=95
$$

anonymous · Answer

So when he threw the ball he was 95 ft above sea level.

Mhm.

anonymous · Answer

So a ladder likely... or a really high up bridge

shamil98 · Answer

I would say a bridge..
or a ladder, 
but i doubt he would be on a ladder that's 95 ft

Whatever, who cares.
