Question

Calcule a distância entre os pontos dados:
a)A(-2,5)B(2,6)
b)M (-3,-4) e (0,2)

Answer 1

Resposta:

Explicação passo-a-passo:

$a)d_{AB}=\sqrt{(x-x_o)^{2}+(y-y_o)^{2}}\\d_{AB}=\sqrt{(2-(-2))^{2}+(6-5)^{2}}\\d_{AB}=\sqrt{4^{2}+1^{2}}\\d_{AB}=\sqrt{16+1}\\d_{AB}=\sqrt{17}\\\\d_{MO}=\sqrt{(0-(-3))^{2}+(2-(-4))^{2}}\\d_{MO}=\sqrt{3^{2}+6^{2}}\\d_{MO}=\sqrt{9+16}\\d_{MO}=\sqrt{25}\\d_{MO}=5$
