Answer:
D. the ball has been traveling for 5 seconds when it reaches the bottom of the ramp
Step-by-step explanation:
f(x) = x²- 10x + 25
We can factor this.
What 2 numbers multiply to 25 and add to -10
-5 *-5 = 25
-5+-5 = -10
f(x) =(x-5) (x-5)
Using the zero product property, we know that it will cross the axis at x=5
At 5 seconds f(x) =0. This means the height is zero at 5 seconds
First one is the correct one, because it is asked for a sum of 1 and 6, which is (1+6), and then all of that divided by 7 => (1+6)/7
