Sandy is working with a carpenter to frame a house. They are using -foot-long boards, but each board must be cut to be feet, inches long. How much is cut off each board?

He is right i did this thing before

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.
