Δabc with vertices a(-3, 0), b(-2, 3), c(-1, 1) is rotated 180° clockwise about the origin. it is then reflected across the line y = -x. what are the coordinates of the vertices of the image?
a'(0, 3), b'(2, 3), c'(1, 1)
a'(0, -3), b'(3, -2), c'(1, -1)
a'(-3, 0), b'(-3, 2), c'(-1, 1)
a'(0, -3), b'(-2, -3), c'(-1, -1)

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)

The figures below are made out of circles, semicircles, quarter circles, and a square. 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).

You are standing next to a really big circular lake. you want to measure the diameter of the lake, but you don't want to have to swim across with a measuring tape! you decide to walk around the perimeter of the lake and measure its circumference, and find that it's 400\pi\text{ m}400? m. what is the diameter dd of the lake?
