Joe plans to put a swing set inside a sand box he is building in his yard. he needs the sandbox to be 5 feet longer than twice the width for safety purposes. joe has 220 feet of material that he will use for the perimeter of the sandbox. if l is the length of the sandbox and w is the width, which system of equations represents this situation?

107.5 is the width

220=2w+5    is the equation

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.
