Sally is giving manicures and styling hair for the women at the shelter from 8am - 4pm each day this weekend. On Saturday she gave six manicures and styled 5 ladies' hair. On Sunday, she gave 10 manicures & 3 hair styles. How long does each manicure and hair styling take?

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.
