Beginning with the function y = sin x, which would have range from -1 to 1 and period of 2pi:
Vertical compression of 1/2 compresses the range from -1/2 to 1/2
Phase shift of pi/2 to the left
Horizontal stretch to a period of 4pi, as the crests are at -4pi, 0, 4pi
Vertical shift of 1 unit up moves the range to 1/2 to 3/2
So the first choice looks like a good answer.
So a hack is we know that 20% times 5 =100% and 40 divided by 2=20 so
50=40%
divide both sides by 2
25=20%
20 times 5=100 so
multiply both sides by 5
125=100%
Your gonna divide 72 by 2 so therefore you get 36
So that equals to Nicole’s age
