There are total of 274 ball in a basket each of which color is either red, white, blue. If the ratio of blue to red is 4:1, the ratio of blue to white is 16:77. How many white ball than red ball in the basket ?

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.
