If a reflection takes triangle cat to c'a't', what is a'c'?

triangle cat with vertex a at negative 2 comma 1, vertex t at negative 1 comma 4 and vertex c at 0 comma 0, side at has a measure of 3 units, side tc has a measure of 4 units, and side ac has a measure of 5 units

Did you get there answer to 44?

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.
