Vertical asymptote at x=4
f(x) approaches 2 as x approaches infinity and f(x) approaches infinity as x approaches 4
Answer:
36=b^2 or b=the square root of 36
Step-by-step explanation:
The sides of a square are all equal in length. To find the area of a square you can multiply the two sides together. Considering that they are the same length, you can just square one of the side lengths to get your answer. To find a side length you can take the square root of the area.
D. is the answer to your question, welcome :3
Answer:

Step-by-step explanation:
step 1
Find cos α
we know that

we have

substitute




Remember that Angle α lies in quadrant II
so
sec α is negative

Find the value of cos α

so

step 2
Find sin α
we know that


we have


substitute


step 3
Find sin β
we know that

we have

substitute





Remember that
Angle β lies in quadrant IV
so
sin β is negative

step 4
Find cos(α−β)
we know that

we have




substitute the given values
