Try this solution (note, this is not the only way):
Q1: if sin(x- 3pi/2)=-sin(3pi/2- x)=--cosx=cosx, then sin(x- 3pi/2)=cosx and sin(x- 3pi/2)=<u>7/25</u>.
Q2: if tan(x)=√3 and x∈(180°;270°), then x=arctan√3+180°=60+180=240°.
If x=240°, then sin(x-210°)=sin30°=<u>0.5</u>.
You multiply 2 both equations and move 14x to left
Answer:
$0.81
Step-by-step explanation:
Find 5.5% of 14.75 by multiplying it by 0.055
14.75(0.055)
= 0.81255
Round this to the nearest cent:
= 0.81
So, the tax will be $0.81
