Question

calcule a distancia entre os ponto E(-3,-6)EF(-3,12)

Answer 1

E(-3,-6)
F(-3,12)

xE = - 3
xF = - 3

yE = - 6
yF = 12

$d_{EF} = \sqrt{(xF-xE)^2+(yF-yE)^2}$

$d_{EF} = \sqrt{[-3-(-3)]^2+[12-(-6)]^2}$

$d_{EF} = \sqrt{(-3 + 3)^2+(12+6)^2}$

$d_{EF} = \sqrt{(18)^2}$

$d_{EF} = 18$ unidades de comprimento
