Question

A distancia os pontos M (3/2,2) e B ( -1/2,1/2)

Answer 1

Explicação passo-a-passo:

$d_{MB}=\sqrt{(x_B-x_M)^2+(y_B-y_M)^2} \\ \\ d_{MB}=\sqrt{(-{1\over2}-{3\over2})^2+({1\over2}-2)^2} \\ \\ d_{MB}=\sqrt{(-{4\over2})^2+({1-4\over2})^2} \\ \\ d_{MB}=\sqrt{(-2)^2+(-{3\over2})^2} \\ \\ d_{MB}=\sqrt{4+{9\over4}} \\ \\ d_{MB}=\sqrt{{16+9\over4}} \\ \\ d_{MB}=\sqrt{{25\over4}} \\ \\ d_{MB}={5\over2}$
