The number of second it takes the apple to hit the ground is 4 seconds
To answer the question, we need to know what functions are
Functions are mathematical equations that show the relationship between two variables
Given that when an apple is dropped from a tower 256 feet high, the function h(t) = -16t² + 256 modelshe height of the apple, in feet, after t seconds.
The time it takes the apple hits the ground is when h(t) = 0
So, h(t) = 0
-16t² + 256 = 0
-16t² = -256
t² = -256/-16
t² = 16
t = ±√16
t = ±4
Since t ≥ 0, t = 4 seconds
So, the number of second it takes the apple to hit the ground is 4 seconds
