* Use the formula below to find the area of a trapezoidal pool with a
height of 15 yds and bases of 14 yds.
and 26 yds.

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.

31/6= 19/6 19/6 *1/7=19/42
