A rocket was launched into the air from a platform above the ground. The height, in feet, of the rocket above the ground t seconds after being thrown can be determined by the expression -16t^2 + 64t +80. What does the 80 in the expression represent?

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6

i those same problems in math and dont know how to do them
