Step-by-step explanation:
your going to distribute the 2 to the x and the four your equation will then become (2x-8)=-5 you would then do the opposite of subtraction which is add so add +8 to the -8 and that cancels it out then you would +8 to the -5 and get 2x=3 then I'm confused from there hope that helps kinda
Answer:
22.5 i think should be your answer
Assuming Earth's gravity, the formula for the flight of the particle is:
s(t) = -16t^2 + vt + s = -16t^2 + 144t + 160.
This has a maximum when t = -b/(2a) = -144/[2(-16)] = -144/(-32) = 9/2.
Therefore, the maximum height is s(9/2) = -16(9/2)^2 + 144(9/2) + 160 = 484 feet.
