Question

Qual valor representa a distância do ponto G(1,-3,2) ao plano A: 2x-4y+4z-4=0?

Answer 1

Resposta:

Explicação passo-a-passo:

$d=\dfrac{2.x_G-4.y_G+4.z_G-4}{\sqrt{2^{2}+(-4)^{2}+4^{2}}}\\\\\\d=\dfrac{2.1-4.(-3)+4.2-4}{\sqrt{4+16+16}}\\\\\\d=\dfrac{2+12+8-4}{\sqrt{36}}\\\\\\d=\dfrac{18}{6}\\\\\\\boxed{d=3}$
