Most evenings after dinner Duarte spends 303030 minutes playing chess with his dad.
Write an equation for the number of minutes, mmm, that Duarte spent playing chess with his dad if they played chess together eee evenings.

Ithink the answer is: it is likely.

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.
