Answer:
Option 4
Step-by-step explanation:
Given:
Sinθ = 
Since, cos2θ = 1 - 2sin²θ
cos2θ = 
cos2θ = 1 - 
cos2θ = 
cos2θ = 
Therefore, Option 4 will be the answer.
Answer:

Step-by-step explanation:
Put the value of x where x is and do the arithmetic.
-7·9 +6 = -63 +6 = -57
The <em><u>correct answer</u></em> is:
C. Both (house, complete mailing address) and (complete mailing address, house) are functions.
Explanation:
A function is a relation in which each element of the domain (x-values) is mapped to one element of the range (y-values).
In the set (house, complete mailing address), the values of "house" would be the domain and the values of "complete mailing address" would be the range. In order to be a function, each value of "house" would be mapped to only one value of "complete mailing address." This is true; each house will have only one complete mailing address. This means it is a function.
In the set (complete mailing address, house), the values of "complete mailing address" would be the domain and the values of "house" would be the range. In order to be a function, each value of "complete mailing address" would be mapped to only one value of "house." This is true; each complete mailing address would go with only one house. This means it is a function.
No, this is because they are not proportionate to eachother
Answer:
6/12=1/2
Step-by-step explanation:
6/12_1/12
