Emily needs to buy fabric to make curtain panels for her windows. each panel will be 4 feet long and 1/2 foot wide. each piece of fabric that she can buy is 4 feet long and 2 feet wide . how many panels can she make from i piece of fabric?

She can make 4 pieces of fabric from 1 piece of fabric. 2 divided by 1/2 equals 4.

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.
