CitiCell has a tower 35 miles east and 42 miles south of Grove Park. The tower emits a signal that reaches receivers within 40 miles of its location. There is a dial with four different settings which will increase the signal by specified amounts. Which settings on the dial will allow the signal to reach Grove Park? Select all that apply.

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.
