The first class (class a) is using a ratio of three parts salt to five parts water. the other class (class b) is using a ratio of two parts salt to four parts water. make an equivalent ratio table for each class to represent its solution. each table should show at least three equivalent ratios. make sure to indicate which ratio table belongs to which class.

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.
