Question

Determina a distância entre os pontos A( -1, 2) e b (-2,5)

Answer 1

Olá !

Resolução :

$\mathsf{Dab =\sqrt{(Xb - Xa)^{2} + (Yb - Ya)^{2}}} \\\\\\ \mathsf{Dab =\sqrt{(-2 -(-1))^{2} + (5 - 2)^{2}}} \\\\\\ \mathsf{ Dab =\sqrt{(-2 + 1)^{2} + (5 - 2)^{2}}} \\\\\\ \mathsf{Dab =\sqrt{(-1)^{2} + 3^{2}}} \\\\\\ \mathsf{ Dab =\sqrt{(1 + 9}} \\\\\\ \mathsf{Dab =\sqrt{10}~~U.C}$

$\texttt{RESPOSTA ~~:}$

A distância é √10 U.C
