Which of the following is an example of the associative property? 2(5 - 3) = 10 - 6
-7 + (19 + 5) = (-7 + 19) + 5
11 + (6 + 8) = 11 + (28 + 6)
· 3 = 1

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.

59/96 is the ratio hope this not 100% sure though : /
