Ana dives into a pool off of a springboard high dive. her height (in meters above the water, x seconds after diving, is modeled by h(x)=-5(x+1)(x-3) how many seconds after diving will ana hit the water?

She will hit the water after 3 seconds.

Step-by-step explanation:

Given,

Ana's height above water is modeled by,

Where, x is the number of seconds after diving.

When, she hit water, h(x) = 0

   ( Dividing both sides by -5 )

By zero product property,

⇒ x = - 1 or x = 3

Since, time can not be negative,

So, x = 3

Hence, she will hit the water after 3 seconds.

answer: just subtact the units and then add the non negative : happy to
