Her goal is to walk 10,000 steps each day. She measures her average step length to be 30 inches. When Janet runs, her average step length increases to 36 inches. How many steps would she have to take to run 1 mile (5,280 feet)? Round to the nearest step.

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.
