What is the percent increase if your salary went from $95 to $100 per week? round your answer to the nearest tenth, if necessary.

%change=100(final-initial)/initial, in this case:

%change=100(100-95)/95

%change=100(5)/95

%change=500/95

%change=100/19 %

%change≈5.26%  (to nearest hundredth of a percent)

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.
