A clothing store had 300 hats on sale . Mr. V bought 12 hats and his four friends each bought a certain number of hats . Write an expression to represent how many hats Mr. V and his friends purchased?

Jim has run 5/6 of a mile so far. i hope that answers your question! 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.
