Question

PLS HELP IM GIVING AWAY 50 POINTS

A diver jumps from a diving board that is 24 feet above the water.
The height of the diver is given by:
h=-16(t-1.5)(t+1)
Where the height h is measured in feet, and the time t is measured in seconds. When will the diver hit the water? Can you see a quick way to find the answer? EXPLAIN

Answer 1

1.5seconds

Explanation:

sorry no step by step explanation but I can guarantee you that the answer is correct and please mark as brainless bye have a great day! :D

Answer 2

t =1.5 seconds

h =0 ft

Explanation:

h=-16(t-1.5)(t+1)

this function crosses the t axis when the diver hits the water

set the equation equal to 0

0=-16(t-1.5)(t+1)

divide by -16

0 =(t-1.5)(t+1)

we can use the zero product property to find when this happens

t-1.5 =0 t+1 =0

t = 1.5 t= -1

time cannot be negative

t =1.5 seconds

the height will be 0 when the diver hits the water
