I believe your answer is 6 seconds.
Because the height of the ball = -16(x² - 5x - 6), when the height of the ball is 0, which is when it is on the ground, we can set -16(x² - 5x - 6) equal to 0. This also allows us to divide by -16, and then we can solve the equation:
x² - 5x - 6 = 0
(x - 6)(x + 1) = 0
So x = 6 or x = -1, and because a quantity of time cannot be negative, x would have to be 6, which means it takes 6 seconds for the ball to reach 0 feet.
I hope this helps!
It would be 5x?=60 because to find "?" you would need to divide 60 and 5. Since Hector earned 5 times what he did last week it would be modeled by 5 times "?"
Answer:
angle D = 54°
Step-by-step explanation:
Supplementary angles sum to 180°
To calculate D, subtract angle C from 180
angle D = 180° - 126° = 54°
