Question

Gente respondam pra mim ???

Answer 1

Resposta:

Explicação passo-a-passo:

a)

$d_{AB}=\sqrt{(x-x_o)^2+(y-y_o)^2}\\d_{AB}=\sqrt{(9-3)^2+(3-3)^2}\\d_{AB}=\sqrt{(6)^2+(0)^2}\\d_{AB}=\sqrt{36}\\d_{AB}=6$

b)

$d_{AB}=\sqrt{(5-5)^2+(-7-6)^2}\\d_{AB}=\sqrt{(0)^2+(13)^2}\\d_{AB}=\sqrt{169}\\d_{AB}=13$
