Avis dining room measures 124 square feet and is in the shape of a square which is the best estimate of the length of one side of the room to the nearest tenth of a foot

The answer would be -3.9> -4.5

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.
