The swimming pool at spring valley high is a rectangle with a width of 65 meters and a length of 30 meters. around the perimeter of the pool is a tiled floor that extends (w) meters from the pool on all sides. find an expression for the area of the tiled floor

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.
