Question

Determine a distância entre os pontos A(1. 3) e B(-3,3)​

Answer 1

Olá !

Conforme sugere o enunciado , calcularemos a distância .

$\mathsf{dAB=\sqrt{(X_{B}-X_{A})^{2}+(Y_{B}+Y_{A})^{2}}} \\\\\\ \mathsf{dAB=\sqrt{((-3)-1)^{2}+(3-3)^{2}}} \\\\\\ \mathsf{dAB=\sqrt{(-4)^{2}+(0)^{2}}} \\\\\\ \mathsf{dAB=\sqrt{16+0}} \\\\\\ \mathsf{dAB=\sqrt{16}} \\\\\\ \boxed{\mathsf{dAB=4~~U.C}}$

Portanto , a distância é 4 U.C
