The price of a pair of shoes is $63.20. the sales tax rate is 4.5 percent. how much sales tax would you pay if you bought these shoes?

Tax rate is 4.5 percent of the item cost so if you buy shoes that cost 63.20 you have to pay 4.5 percent of this value as tax so write 4.5 percent as a fraction or decimal then multiply it by the item cost.

Therefore, 63.20 x .045 = $2.84

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.
