Juana and 11 friends are having a pizza party. each person will eat 3/8 of a pizza. how much pizza will be eaten at the party?

If each person eats 3/8 of a pizza and there are 11 people, then they will eat 3/8 × 11 pizzas

3/8 × 11 = 33/8 = 4 1/8

They will eat 4 and 1/8 pizzas

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.
