14. The diameter of a circle has endpoints A(-8, -5) and B(4, 11). Write the equation of the circle. (**hint: you must find the center and radius)

x² + y² - 12x - 16y = 280

Step-by-step explanation:

The diameter of a circle has endpoints A(-8,-5) and B(4,11)

The equation of a circle is given by: (x - a)² + (y - b)² = r² , Where x and y are points on the circle and (a, b) is the center of the circle. r is the radius.

To find the center of the circle:

Center = (,) = (6, 8)

The length of the diameter is the square root of change in y squared plus change in x squared.

The length of the diameter squared = (11 - -5)² + (4 - -8)² = 400

The diameter is = 20 units

Taking another point (x,y) on the circle,

The equation of the circle will be:

(x - 6)² + (y - 8)² = 20²

Simplifying this gives;

x² - 12x + 36 + y² - 16y + 84 = 400

x² + y² - 12x - 16y = 400 - 84 - 36

x² + y² - 12x - 16y = 280

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
