Answer:
im pretty sure its the 3rd one
X=8.
Let me explain.
2x-16=0
add 16 to both sides
2x=16
divide both sides by 2
x=8
In order to solve you get x by itself:
5-x=12
-5 -5
-x=7
divide by negative 1
For this case we have the following equation:
h = -16t ^ 2 + 32t + 6
Deriving we have:
h '= -32t + 32
We equal zero and clear t:
-32t + 32 = 0
32t = 32
t = 32/32
t = 1 s
Then, the maximum height is given by:
h (1) = -16 * (1) ^ 2 + 32 * (1) + 6
h (1) = 22 feet
Answer:
It takes the ball to reach its maximum height about:
t = 1 s
The ball's maximum height is:
h (1) = 22 feet
