An artist is laying out the design for a wall hanging on a coordinate plane. She uses polygon EFGH with
vertices E (4,4), F (-4,4), G (-4,-4), and H (4, -4) to
represent the finished piece. What is the perimeter of
this polygon?

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.

C+19÷-17=17c+(-1.11764706)=17c=.11764706)c=18.1176471
