PLEASEHELP Martha can paint a room in 11 hours. Jamie can paint the same room in 2 hours. How long, to the nearest tenth
of an hour will it take them to paint the room together?

What’s your question.

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.
