Question

qual a distância A(1,3)eB(5,6)

Answer 1

Bom dia !

Observe o esquema abaixo...

$\mathsf{D_{\overline{AB}}=\sqrt{\left(X_{B} - X_{A})^{2} + (Y_{B} - Y_{A}\right)^{2}}} \\\\\\ \mathsf{D_{\overline{AB}}=\sqrt{\left(5 - 1)^{2} + (6 - 3\right)^{2}}} \\\\\\ \mathsf{D_{\overline{AB}}=\sqrt{(4)^{2} + (3)^{2}}} \\\\\\ \mathsf{D_{\overline{AB}}=\sqrt{(16 + 9)}} \\\\\\ \mathsf{D_{\overline{AB}}=\sqrt{25}} \\\\\\ \mathsf{D_{\overline{AB}}=5~~U.C}$

$\textbf{RESPOSTA~~:}$ 5 U.C
