Mandy bought school supplies for her two kids at the beginning of the school year. She spent a total of $. 49.50 on 5 binders and other miscellaneous items. How much did each binder cost if $27 was spent miscellaneous items . A) 27 + 5x=$49.50 B) 27+49.50=5x C) 49.50-27 divided by 4=5x D. 5x+27 divided by 4=49.50

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.
