Question 2 Given AOPD in the coordinate system below. D 3 D 0 1 2 1 2 P 0 a) To the nearest hundredth of a unit, find the approximate perimeter of the triangle above. b) If each block is equal to 50 ft2, then determine the area of AOPD.

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.
