Lisa takes a loan of $10,500 at a 9% simple interest rate for 7 years. How much interest will she pay after 3 years? How much interest will she pay in total for the loan? A. $2,835.00; $6,615.00 B. $8,280.00; $9,720.00 C. $13,598.00; $19,194.00 D. $28,350.00; $66,150.00

The correct answer is .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.

Recall that area of the triangle is 1/2*(base)*(height)1/2*(13)*(17) = 110.5the answer is 110.5
