Answer:
p=4
Step-by-step explanation:
In the left/right direction, your circle (at it's biggest point) goes from -5 to 5
the middle of -5 and 5 is 0
so the center of your circle should have a x = 0
in the (x , y) point
the only option that has
(0, something)
is C
Therefore your answer is C
Answer:A standard form is a form of writing a given mathematical concept like an equation, number, or an expression in a form that follows certain rules. Representing very large or very small numbers concisely, the standard form is used. For example, 4.5 billion years is written as 4,500,000,000 years.
Step-by-step explanation:
Multiply both the numerator and denominator by 
, which is called the "conjugate" of 
:
Why do we pick this number? Recall the difference of squares factorization:
Now replace 
and 
. Then
So in your fraction, you end up with
Finally, just expand the product.
