Question

Hallar el radio de la circunferencia de C(-3,2), tangente a la recta 2x + 3y = 13

Answer 1

Explicación paso a paso:

2x + 3y = 13

3y = 13 - 2x

y = 13/3 - 2x/3

x = 0 ; y = 13/3  (0, 13/3) = (0, 4.3)

x = 13/2 ; y = 0  (13/2, 0) = (6.5, 0)

(x, 2)

y = 13/3 - 2x/3

2x/3 = 13/3 - 2

2x/3 = 7/3

x = 7/2 = 3.5
