Hi, I need help with this question and I need an explanation pls. Please don't copy the answer from the internet. Here's the question: A ball is thrown into the air from the top of a building. The height, h(t), of the ball above the ground t seconds after it is known can be modeled by
h(t) =-16t²+16t+80. How many seconds after being thrown will the ball hit the ground?

−16(2−−5)

Step-by-step explanation:

hay un factor común entre estos números, por lo que simplemente −16t2+16t+80 divida y reutilice y luego reciba−162+16+80 llegar

−16(2−−5)

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.
