A baseball is projected upward at 64 feet per second. It can be approximated by the equation - 16t^2+64t. The baseball reaches it maximum
height at the vertex. That can be gotten from x= –b/2a
How long until the
baseball reaches its full height? Note a quadratic equation can be written as
ax^2+bx+c

we need more info to solve this

hey i’m new i won’t be answering any questions now bye peeps see you next time

d

step-by-step explanation:

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.
