Given point U is the midpoint of XY. If XY = 16x - 6 and UY = 4x + 9, find the value of x and the measure of XY I think I have the correct answer, I just want further assurance.

The first option would be correct if it were one half and not one

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.
