The equation y=−3.5x2−0.5x+65 models the height of a ball in inches for each bounce. note it's 3.5x to the second power. what is the best approximate for the height of the ball after the 3rd bounce? 7 in. 14 in. 32 in. 50 in.

Given equation is y = -3.5x-0.5x+65

y represents the height of the ball and x represents the number of bounces.

After 3rd bounce, so plug in x= 3 in the given equation, we get

Y=-3.5(3)-0.5(3) + 65

y = - 3.5 (9) - 0.5(3) + 65

y = - 31.5 - 1.5 + 65

y = -31.5 - 1.5 +65

Y = - 33 + 65

y = 32

So best approximate height of the ball after 3rd bounce is 32 in.

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.

faster, im not sure why but i know it is faster
