Share 54 in the ratio 5:4

30:24 is the answer for that

Sorry I don’t know this one but I have learned this I just was sleeping but I don’t remember but I did learn this good luck

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.
