Answer:

{y}  =  6\sqrt{3} \:units

Step-by-step explanation:

By Pythagoras Theorem:

{y}^{2}  =  {(9 + 3)}^{2}  -  {(6)}^{2} \\  \\   {y}^{2}  =  {(12)}^{2}  -  {(6)}^{2} \\  \\   {y}^{2}  = 144 -  36 \\  \\  {y}^{2}  = 108 \\  \\  {y}  =  \sqrt{108}  \\  \\  {y}  =  \sqrt{36 \times 3}  \\  \\ {y}  =  \sqrt{ {6}^{2}  \times 3}  \\  \\ {y}  =  6\sqrt{3}\:units

Find the center and radius of the circle whose equation is x 2 + y 2 + 10x − 1
Margaret [11]

we conclude that the center of the circle is the point (-5, 0).

<h3>How to find the center of the circle equation?</h3>

The equation of a circle with a center (a, b) and a radius R is given by:

(x - a)^2 + (y - b)^2 = R^2

Here we are given the equation:

x^2 + y^2 + 10x - 1 = 0

Completing squares, we get:

x^2 + 10x + y^2 = 1

Now we can add and subtract 25 to get:

x^2 + 10x + 25 - 25 + y^2 = 1\\\\(x + 5)^2 -25 + y^2 = 1\\\\(x + 5)^2 + (y - 0)^2 = 26

Comparing that with the general circle equation, we conclude that the center of the circle is the point (-5, 0).
