Mr. henry expected 10 of the students his drama class to attend the school play. instead,15 students in his class attended, what percentage more students attended the play than was expected?

50% more.

5 more students attended other than the expected 10. 5/10 is the same as 1/2, or 50%.

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.
