. The height, h, of an object above the ground in feet, can be modeled as a function of time, t, in seconds using the equation:
h(t)=-16(t - 2)^2 + 400
Find the time, in seconds, when the object reaches the ground.

(Please help, I’ll give you brainlist too. I need this ASAP. Also PLEASE add an explanation too, the steps)

27 +27 or 27times 2=54

the diffrence is 0

just took the test and my answers down below!

step-by-step explanation:

check the pic :

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
