Does anyone know how to do this

a. If , then , so

b. When , we're told has a horizontal tangent, which has slope . So we have

where is any integer, whose smallest positive value occurs for , giving .

c. The equation is separable:

Integrate both sides to get

when , so we find

Then the particular solution to the DE is

answ9x x 3=

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
