Question

A player shoots a basketball from a height of 6 feet. The equation, h = -16t 2 + 25t + 6, gives the height, h , of the basketball after t seconds. Describe the height, rounded to the nearest tenth of a foot, of the basketball after 1.5 seconds, assuming no other player touches the ball.

_____________________feet above the ground

Answer 1

All you need to do is to replace
`t` in given equation with
`1.5`:

`h=-16*1.5^2+25*1.5+6=-16*2.25+37.5+6=`

`=-48.375+37.5+6=-4.875`
The value is negative so we can assume that after 1.5 seconds the ball will be 4.875 foot lower than it was shot from. But we also know that it was shot from height of 6 feet, so it will be 6 - 4.875 = 1.125 feet above the ground or 1.1 feet (rounded to the nearest tenth of a foot)

Answer 2

thanks for the answer turns out his third guess was the right its 7.5 feet
