Afootball team starts with the ball at their own 20-yard line. they make two 6-yard gains in a row, then they have three 5-yard losses in a row. what yard line is the ball on at this point?

20+2(6)-3(5)=20+12-15=27

The ball is 27 yard line :)

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.

That is right sorry i was gonna answer but i already saw his
