Question

calcule as distancia entre os pontos a(4,7) e b(4,1)

Answer 1

$\large\boxed{\begin{array}{l}\underline{\sf dist\hat ancia~ entre~ dois~ pontos:}\\\boxed{\boxed{\sf d_{AB}=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}}}\\\sf d_{AB}=\sqrt{(4-4)^2+(1-7)^2}\\\sf d_{AB}=\sqrt{(0)^2+(-6)^2}\\\sf d_{AB}=\sqrt{0+36}\\\sf d_{AB}=\sqrt{36}\\\sf d_{AB}=6 ~\checkmark\end{array}}$
