Write 702,001 in expanded form. (no spaces in answer)

Here is the expanded form for the given number above.
It would be 700,000+2,000+1. Expanded form is the way on how we write or present the values of its digits by addition. Other example that might help you is this. 541. In this case, the expanded form is 500+40+1. Hope this answer helps you. 

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.
