$46 shoes; 2.9% tax. find the total cost to the nearest cent.

To get the answer we have to find 2.9% of 46 and add it to 46.
2.9% is 0.029
46*0.029=1.334$
46+1.334=47,334

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.
