An apple is launched directly upward at 64 feet per second from a platform 80 feet high. The equation for this apple's height h at time t seconds after launch
is h(t) = -16t+ 64t + 80. What is the height of the apple after 3 seconds?
64 ft

128

explaination:

-16(3)^2+64(3)+80 which equals 128, you can also type this into a calculator and see where the line crosses, where x=3 btw is the -16t suppose to be squared or??

450 is the final answer! : )

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this
