Answer 3

thank you :D

Answer 4

The standard form equation of a circle is a way to express the definition of a circle on the coordinate plane.
Definition of Circle

Definition: A circle is the set of all points that are the same distance, r, from a fixed point.
General Formula: \(X^2 + Y^2=r^2\) where r is the radius

Unlike parabolas, circles ALWAYS have \(X^2\) and \(Y^2\) terms.

\(X^2 + Y^2=4\) is a circle with a radius of 2 (since 4 =22)

Remember that a circle is a locus of points. A circle is all of the points that are a fixed distance, known as the radius, from a given point, known as the center of the circle.

Answer 5

try the formula out ;)

Answer 6

okay, i got (x + 4)2 + (y – 5)2 = 5.5

Answer 7

is that right?
