What number must be added to 14,056 to result in a sum of 32,713

14,056 + x = 32,713

Subtract 14,056 from each side

x = 18,657

18,657 // all you have to do is take the sum ( 32,713 ) and subtract it from the other number

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.
