Question

Achar as distâncias entre os seguintes pares de pontos:
A e B

Sendo: A(4 e 3) e B(5 e 0)

Answer 1

$a(4 ;3)~e~b(5; 0)\\\\ D_{ab}= \sqrt{(x_b-x_a)^2+(y_b-y_a)^2} \\\\ D_{ab}= \sqrt{(5-4)^2+(0-3)^2} \to \\\\ D_{ab}= \sqrt{(1)^2+(-3)^2} \to \\\\ D_{ab}= \sqrt{1+9} \to \\\\ \boxed{D_{ab}= \sqrt{10} }$
