Question

determine a distância entre os pontos A(0,0) e B(3,1)

Answer 1

$D_{ab}= \sqrt{(x_2-x_1)^2+(y_2+y_1)^2} \\\\\\\\D_{ab}= \sqrt{(3-0)^2+(1-0)^2} \\\\\\D_{ab}= \sqrt{9+1} \\\\\\D_{ab}= \sqrt{10}$


Forte abraço!

Answer 2

A(0,0) e B(3,1)

D² = ( xb - xa )² + ( yb - ya )²

D² = ( 3 - 0 )² + ( 1 - 0 )²

D² = 3² + 1²

D² = 9 + 1

D = √10
