3. if an object is dropped from a height of 100 ft, the function h(t) = -16f+
100 gives the height of the object after t seconds. when will the object hit the
ground?

When t = 25/4 the object his the ground.

Step-by-step explanation:

When the object hit the ground, the distance from it to the ground (or height) will be 0.

Thus,

if when the object touch the ground is when h = 0 then h(t) = 0

So we can set up this equation :

0 = -16t + 100

-100 = - 16t

-100/-16= 25/4 = t

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
