100 points need answer asap!! The diameter of Circle Q terminates on the circumference of the circle at (3,0) and (-4,0). Write the equation of the circle in standard form. Show all of your work for full credit.

Step-by-step explanation:

Since the diameter of Circle Q terminates on the circumference of the circle at (3,0) and (-4,0), the diameter lies on the x-axis.

The midpoint of the ends of the diameter gives the center of the circle.

The radius of this circle is the distance from the center to one of this points on the circumference.

The equation of the circle is given by

where (a,b)=(-0.5,0) is the center and r=3.5

We substitute to get:

The standard form equation is

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
