Answer:
3 seconds
Step-by-step explanation:
When the ball hits the ground, the height will be 0. Therefore, you can substitute 0 in for the value of f(t), hence the equation will be:
0 = -16t^2 + 32t + 48
You can then factor out -16:
0 = t^2 - 2t - 3
Factor:
0 = (t-3)(t+1)
t = 3, -1
However -1 is an extraneous solution because time cannot be negative. Therefore, the answer is 3 seconds.
Answer:
The point (-8,7) is the reflection of the point (8,7)
Answer:
<em>B. 25,636 feet</em>
Step-by-step explanation:
sin(55) = h/x
h = 21,000
sin(55) = 21,000/x
x = 21,000/sin(55)
x = 25636.27 ≈ 25,636 feet
Hope this helped! :)
