1. A new basketball costs $22.00 but is on sale for 40% off. If sales tax is 5%, what is the final cost of the
basketball? Enter your answer as dollars and cents,

Ais the correct answer

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.
