Question

Alguien que me ayude con esto o me pueda explicar

Answer 1

Respuesta:

1. x² + y² - 8x - 6y + 616/25 = 0

2. x² + y²- (4x/3) - (7y/4) - (8519/576) = 0

Explicación paso a paso:

1.

C(4,3)

r = -3/5

(x-h)² + (y-k)² =r²

(x-4)² + (y-3)² = (-3/5)²

x² - 2(x)(4) + 4² + y² - 2(y)(3) + 3² = (9/25)

x² - 8x + 16 + y² - 6y + 9 = 9/25

x² + y² - 8x - 6y + 25 - 9/25 = 0

x² + y² - 8x - 6y + 616/25 = 0

2.

C(2/3, 7/8)

r = 4

(x-2/3)² + (y-7/8)² =4²

x² - 2(x)(2/3) + (2/3)² + y² - 2(y)(7/8) + (7/8)² = 16

x² - (4x/3) + (4/9) + y² - (7y/4) + (49/64) - 16 = 0

x² + y²- (4x/3) - (7y/4) - (8519/576) = 0
