Find an equation of a parabola with a vertex at the origin and directrix y = -1.5.

a) x = -1/6 y^2
b) x = 1/6 y ^2
c) y = -1/6 x^2
d) y = 1/6 x^2

The answer is A. If you graph it you can see the answer.

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
