Adisc is thrown into the air with an upward velocity of 20 ft/s. its height h in feet after t seconds is given by the function h(t) = -16t^2 + 20t + 6

when does the disc hit the ground?

.

step-by-step explanation:

.

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
