Aball is thrown vertically upward from the top of a building with an initial velocity of 96 feet per second. the ball's h height after t seconds is given by the equation h = −16t2 + 96t + 100. how long will it take for the ball to hit the ground? (to the nearest tenth of a second)
a) 5.9 seconds
b) 6.3 seconds
c) 6.9 seconds
d) 7.2 seconds

C

Step-by-step explanation:

The ball's h height after t seconds is given by the equation

When the ball hits the ground, the height is equal to 0, so substitute h = 0 into the function expression and solve it for t:

Since time cannot be negative, the ball will hit the ground in 6.9 seconds

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!

one more happy customer!
