Question

calcule a distancia entre os pontos dados : b)e(3,1ef(3,5)

Answer 1

$Resolu\c{c}\~ao \to \left\{\begin{array}{ccc}(3,1)\ e\ (3,5)\\\\d = \sqrt{(X_b-X_a)^2+(Y_b-Y_a)^2}\\\\d = \sqrt{(3-3)^2+(5-1)^2}\\\\d = \sqrt{0^2+4^2}\\\\\boxed{\boxed{d=\sqrt{4^2} = 4 }} \end{array}\right$

Espero ter ajudado. :))
