Answer:
(6y - 1)(6y + 1)
Step-by-step explanation:
To factorize completely, we may adopt the difference of 2 squares approach. The theory states that difference of two square is the product of the difference of the number and the sum of the numbers.
Such that
a² - b² = (a - b) (a + b)
Hence 36y² - 1
= 6²y² - 1²
= (6y)² - 1²
= (6y - 1)(6y + 1)
The fifteenth customer will be the first because 5x3=15
Yes that’s your answer!! Good job!!
Since the measure of angle 
is 
The measure of its reference angle = 
=
Now we have to compute the value of 
The value of (
) lies in the fourth quadrant. In fourth quadrant, the value of tan is always negative.
So, 
= -1.
