Mary and her dad shared one dozen brownies2/3 of them have nuts, which dad doesn't eat. How many brownies did dad not eat because they had nuts?

 

2/3 x 12 = 8/12 x 12/1 = 24/3 = 8

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.

Ithink your answer is b
