Circle has center ( 3 , 5 ) and the point ( −2 , −7 ) lies on the circle. Select which of the following statements, if any, are true about circle . (GPE. 4) i. The point ( 8 , −7 ) also lies on the circle ii. The Point ( 7 , 4 ) also lies on the circle iii. The radius of the circle is 13 iv. The diameter of the circle is 13

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.
