The ratio of two number is 5: 3 the sum of the number is 16 what are the numbers

One number is [5 / (5+3) ] * 16  and the other = [3 / (5+3) ] * 16

= (5/8) * 16  and (3/8) * 16

= 10 and 6

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.
