Kim got approved for a home mortgage loan with a 7% APR. If the monthly payment for this APR is $6.65 for every $1,000 financed, what would Kim’s monthly payment be if she borrows $200,000?

The answer would be $68.04

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.
