How long did it take the apple to hit the ground? round your answer to the nearest hundredth

2.74 seconds

Step-by-step explanation:

The apple will hit the ground when its height above the ground is zero:

0 = -16t^2 +120

t^2 = 120/16 . . . . . . divide by 16 and add t^2, then simplify and take the square root:

t = √7.5 ≈ 2.73861 ≈ 2.74 . . . . seconds

look a the sides they are perpendicular

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
