PLEASE ANSWER ASAP THANK YOU :]

1. The height of a pop fly ball over the time after the ball is hit is modeled by the function, h(t) = -16t2 + 81t + 5. , where is the ball’s height in feet above the ground and is the time in seconds after the ball is hit. Use the quadratic formula to find how many seconds it takes for the ball to hit the ground.

2. Give an example of a quadratic equation with real solutions.

3. Give an example of a quadratic equation with non-real solutions.

answer: the answer is 35%

i got 86 for this

hope this !

if you need an explanation just ask

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
