SOLVE THE COMPOUND INEQUALITY

I’m pretty sure it’s 4.0

How much is 32 out of 40 written as a percentage? convert fraction (ratio) 32 / 40 answer:   80%

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
