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!

Hey man, it wont work :(
Step-by-step explanation:
nobody will try to help you. Ive been there. GL trying to do it on your own.
Word of advice, Do it next time.
Might be boring or nor fun but its easier in the long run.
7b is just 7 x b and if b is 6 its just 7 x 6
which the answer is 42
42%7=6. 6 times 5 is 30. 30 cakes in 5 days.
