Try this solution (this is not the only way!):
Q1: if cosx=-0.5 and x∈(90;180), it means x=120°.
So, sin(x-30)=sin(120-30)=sin90°=1.
<u>answer</u>: 1.
Q2: it tgx= -1/√3 and x∈(270°;360°), it means x=330°.
So, sin(x+30)=sin(330+30)=sin360°=0.
<u>answer</u>: 0.
the third choice is correct
The factors are: x-5 and x+3
Step-by-step explanation:
Given
Simplifying
Let us define the zero product property first
The zero product property states that
if ab=0 then either a=0 or b=0
So,
Hence,
the factors are: x-5 and x+3

Subtracting a value from the exponent shifts the graph to the right.
So if you subtract 3, the graph would shift 3 units to the right.
Well you can’t if you can’t figure out what x and y is then it’s an equivalent expression so x and y are 1
