There is no logical relationship between the prepositions.
You can put any angle and its cosine there.
You can put, for example:
Cos(90)=0 or Cos(0)=1... Both are correct options...
If your teacher wrote that, he doesn't know to write very good...
Good luck!

Question 1: x+2 = 8 doesn't belong in the given equations.
Question 2: The possible values for y are 0,1 and 2
Step-by-step explanation:
Question: Which one doesn't belong?
We will solve each equation one by one to get which equation doesn't belong with others
So,




Hence,
x+2 = 8 doesn't belong in the given equations.
Question 2:
Given equation is:

It is given that the values of x will be greater than 2 and less than 6 so values of x can be 3,4 and 5
So,

Hence,
The possible values for y are 0,1 and 2
So,
x+2 = 8 doesn't belong in the given equations.
The possible values for y are 0,1 and 2

Answer:
$180
Step-by-step explanation:
Since the cost of the telescope with the 30% discount is $126 then $126 is 70% of the original price. Remember 100-30=70. To find the original price set up a proportion with these values:

Solve for the original price by cross multiplying numerator with denominator.
x(70) = 126(100)
70x = 12600
x= $180
ANSWER
C. 28
EXPLANATION
The given expression is

We want to evaluate this function at x=-2.
We just have to substitute x=-2 into the given expression.
In other words, we have to replace x with -2 wherever we see x in the expression

We evaluate the exponent to get

We multiply next to get:

We now add to obtain:

The correct answer is C
