Question

preciso de ajuda nessa questão!!!​

Answer 1

Resposta:

A) G = (1, 11/3)

B) G = (-2/3, 3)

C) G = (-4/3, -1)

Explicação passo a passo:

A) A (1, 3), B (2, 1), C (0, 7)

$G=(\frac{1+2+0}{3} ,\ \frac{3+1+7}{3} )\\\\G=(\frac{3}{3} ,\ \frac{11}{3} )\\\\\bold{G=(1 ,\ \frac{11}{3} )}$

B) A (-3, 4), B (1, 3), C (0, 2)

$G=(\frac{-3+1+0}{3} ,\ \frac{4+3+2}{3} )\\\\G=(\frac{-2}{3} ,\ \frac{9}{3} )\\\\\bold{G=(-\frac{2}{3} ,\ 3 )}$

C) A (-4, 0), B (0, 0), C (0, -3)

$G=(\frac{-4+0+0}{3} ,\ \frac{0+0+(-3)}{3} )\\\\G=(\frac{-4}{3} ,\ \frac{-3}{3} )\\\\\bold{G=(-\frac{4}{3} ,\ -1 )}$
