Answer: The initial height of the ball is 12 feet.
Step-by-step explanation:
We have the function , which models the height (in feet) of the ball after seconds.
Then, as the height is in function of the time, we know that the ball is in the initial height when:
So, to find the initial height, you need to substitute into the function:
Therefore, the initial height of the ball is 12 feet.

Answer:
Let the fraction be qp
So q=p+7
q−6p+17=2
⇒p+7−6p+17=2
⇒p+1p+17=2
⇒p+17=2p+2
⇒p=15
q=15+7=22
So qp=2215.

The number of ways to choose r objects out of n objects is:
C(n,r) = (n!)/(r! * (n-r)!)
The number of ways to choose 2 numbers out of a list of 9 numbers is:
C(9,2) = 9! / (2! * 7!)
= 9*8 / 2!
= 9*8/2
= 36
