Answer:
Find(fog)(x)
f(x)=2x-10
g(x)=4x+5
Step-by-step explanation:
hello :
(fog)(x)
=f(g(x)) = f(4x+5) = 2(4x+5)-10 = 8x+10-10
(fog)(x)
=8x

Answer:
2
Step-by-step explanation:
The height formula given is:
h = -16t^2 + 70
That means the object will be initially (t=0) at the height 70 feet, from where it will be dropped.
If we want to know the time when the object will be at height 6 feet, we just need to use h=6 in the equation, and then calculate the value of t:
6 = -16t^2 + 70
16t^2 = 64
t^2 =4
t = 2 s
So, it will take 2 seconds for the object to be 6 feet above the valley floor.
