Let U={t, u,v, w,x, y,z}, A={y, w}, B = {v. W}C={t, x,v,} and D={t, W,Z, X,V} Tell whether the statement below is true or false the universal set. ∅⊂D. Is the statement ∅⊂D. True or false?

There is no association.

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.
