Question

03. Calcule a distância entre A(-7, 6)
e B(5, -3).
sk
a) 12
O b) 13
c) 14
O d) 15
O e) 16​

Answer 1

$dAB=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}$

$dAB=\sqrt{(5-(-7))^2+(-3-6)^2}$

$dAB=\sqrt{(5+7)^2+(-9)^2}$

$dAB=\sqrt{12^2+(-9)^2}$

$dAB=\sqrt{144+81}$

$dAB=\sqrt{225}$

$dAB=15$

Gabarito: d)
