A stone is dropped off the edge of a cliff, and it falls for 4.8s before striking
bottom. Approximately how far above the bottom is
the cliff edge, assuming zero air resistance?

y=(1/2)at^2

y=(1/2)(9.8 m/s/s)(4.8 s)^2

y=60.025 m

Step-by-step explanation:

Sry if not right

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
