A 12 foot ladder is leaning on a wall, slowly sliding down. If the bottom of the ladder is sliding down away from the wall at 1/2 ft/sec, how fast is the top of the ladder sliding down the wall, when the bottom of the ladder is 8 feet away from the wall?

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

step-by-step explanation:

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
