Answer:
8 seconds
Step-by-step explanation:
Given :
h(t) = -16t2 + initial height
Initial height = 1024 feets
By the time it hits the ground, h(t) = 0
Equation becomes :
0 = - 16t² + 1024
Solve for t
-16t² = 1024
t² = 1024 / -16
t² = 64
t = √64
t = 8
Hence, it will take 8 seconds
This equation is a line so we expect it to cross at least once.
Set y=0 since on the x-axis y=0 and that is where we need to see when it crosses or touches.
y=-7x+8
0=-7x+8
-8+0=-7x+8-8
-8=-7x
-8/-7=-7x/-7
8/7=x
Real zeros 8/7
