Setting f(x) = 0, we have:
-x2 -7x +30 =0
The roots of this quadratic equation are:
x = 3 and -10
Since the diver is on a diving board, the -10 is somewhere behind him. We use the root x = 3 since this distance is in front of the board.
Therefore, the answer is:
x = 3; the diver hits the water 3 feet away horizontally from the board

Answer:
$6981
Step-by-step explanation:
Let's find the answer by using the following formula:
(this year cost)=(last year cost)+((last year cost)*(percent increase of cost)) so:
3750+3650=X+0.06X where X=last year cost, then:
7400=1.06X
6981.13=X
In conclusion, last year he spent $6981.
I believe the answer would be 70 but make sure just in case.
