Cecily is on her roof and wants to throw a ball straight up in the air and figure out how long it will take to reach the ground. The function that models an object falling to the ground is f(x) = -32x2 + vx + d. In this function, x is time, v is the initial (vertical) velocity in feet per second, and d is the initial distance above the ground in feet. If v is positive, then the initial velocity is upward. If v is negative, the initial velocity is downward. Write the function if Cecily releases the ball 40 feet above the ground at a velocity of 64

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6

happy to

pls mark as brainliest

ratio is 2 : 9

the answer is three

13.5 : 3
