Question

A player shoots a basketball from height of 6ft. The equation, h= -16t2+25t+6 hives the height, h of yhe 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

Answer 1

`h \: = \: - 16 {t}^(2) \: + \: 25t \: + \: 6`
At t = 1.5 s

`h \: = \: - 16{(1.5)}^(2) \: + \: 25(1.5) \: + \: 6`

`h \: = \: - 16(2.25) \: + \: 25(1.5) \: + \: 6`

`h \: = \: 7.5 \: ft`
