An equilateral triangle with a perimeter of 15 units is graphed on a coordinate grid. The triangle is dilated by a scale factor of 0.25, with the origin as the center of dilation. If (x, y) represents the location of any point on the original triangle, which ordered pair represents the coordinate of the corresponding point on the resulting shape?

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.
