What is 396.5divided by 18 but estimate the quotient (estimate the quotient) me

The original answer is 22.02 but estimated it 22 so hoped it helped

22.03. I just rounded it up there since all that is after is a lot of 7s

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.
