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
Every 2 weeks the amount of money needed goes down 3
The answer is c, 8/3 (6) - 16 = 0 therefore 6 is the zero
Answer:
-64
Step-by-step explanation:
If
y=x^2
and the x represents -8
Your answer will be -64
By saying that x=(-8) all you have to do is plug in the negative 8 to the original equation of y=x^2. This would make it y=(-8)^2
When you plug in negative 8 to the second power into the calculator your answer will be -64
