Question

Calcule a distância entre os pontos A = (4, -8,-9) e B = (2, -3, -5). *
1 pont
6.7
5,7
3,7
6,6

Answer 1

Dab = $\sqrt{(xb - xa )^{2} + (yb - ya ) ^{2} + ( zb - za )^{2} }$

Dab = $\sqrt{(4 - 2 )^{2} + ( -8-(-3))^{2} + (-9-(-5))^{2} }$

Dab = $\sqrt{2^{2} + (-5)^{2} + (-4)^{2} }$

Dab = $\sqrt{2 + 25 + 16}$

Dab = $\sqrt{43}$

Dab = 6,6
