Answer:
c 44
Step-by-step explanation:
-117 must be added to complete the square.
Y= 16x2 - 8x+1 does not intersect the c axis. It only peaks at it. The parabola does not go over it.
Answer:
or 
Step-by-step explanation:
Given
Points:
A(-3,2) and B(-2,3)
Required
Determine the radius of the circle
First, we have to determine the center of the circle;
Since the circle has its center on the x axis; the coordinates of the center is;

Next is to determine the value of x through the formula of radius;

Considering the given points



Substitute values for
in the above formula
We have:

Evaluate the brackets


Eva;uate all squares


Take square of both sides
Evaluate the brackets



Collect Like Terms


Divide both sides by 2

This implies the the center of the circle is

Substitute 0 for x

Substitute 0 for x and y in any of the radius formula


Considering that we used x1 and y1;
In this case we have that; 
Substitute -3 for x1 and 2 for y1

Well you would 12 12 because you double the number twice ad you would do 12 in 12 and you get 24
