Eyjafjallajökull is a volcano in ice land. during a recent eruption, the volcano, spewed out copious amounts of ash. one small was ejected from the volcano with an initial velocity of 368ft/sec. the height h, in feet, of our ash projectile is given by the equation h= -16t +368t
1. when does the ash projectile reach its maximum height?
2. what is its maximum height?
3. when does the ash projectile return to the ground?

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

step-by-step explanation:

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
