(cos Θ − cos Θ)² + (cos Θ + cos Θ)²
= 0² + (cos Θ + cos Θ)² ;
= 0 + (2 cos Θ)² = (2 cos Θ)(2 cos Θ) ;
= 4 (cos Θ)² = 4 cos² Θ .

Answer:
B. x= 4
Step-by-step explanation:
We know that,
The result for the intersection of the secant and the tangent is given by by the figure below,
According to the question, we have,
i.e. 
i.e. 
Now, the solution of a quadratic equation 
is given by, 
So, we get,
implies a= 1, b= 12 and c= -64.
Thus, the solution is given by,
i.e. 
i.e. 
i.e. 
i.e. 
and i.e. 
i.e. 
and i.e. 
i.e x= -16 and x= 4.
Since, length cannot be negative.
So, we have, x= 4.
The function tule for the table is
y = 2x
If you line the table vertically, you can see the x value is +1 because how does 0 go to 1, you add one to it.
With the y variable, you can view its being multiplied by 2 since 5x2 = 10 , 10x2 = 20 and so on.
Therefore the function rule is y=2x
The information about the mean and median shows that the females have more number of haircuts than the males.
<h3>What is a mean?</h3>
It should be noted that a mean simply means the average of a set of numbers that are given in a data.
In this case, the information about the mean and median shows that the females have more number of haircuts than the males.
This is depicted since the mean of females is 52.53 and the mean of males is 20.13.
