Question

a distancia entre os ponto A (-4,3)eB(-4;-7) é

Answer 1

$Resolu\c{c}\~ao \to \left\{\begin{array}{ccc}d = \sqrt{(\Delta x)^2+(\Delta y)^2}\\\\d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\d = \sqrt{[-4-(-4)]^2+(-7-3)^2}\\\\d = \sqrt{(-4+4)^2+(-10)^2}}\\\\ d = \sqrt{0^2+100}\\\\\boxed{\boxed{d = \sqrt{100} = 10}} \end{array}\right$

Espero ter ajudado. =^.^=
