Question

determine

a) as coordenadas do seu baricentro

b) o ponto médio de AB​

Answer 1

Resposta:

a)

Pontos A(2,-1) B(4,-3) C(-2,-5)

xG = (2 + 4 + (-2))/3

xG = 4/3

yG = (-1) + (-3) + (-5))/3

yG = -9/3

yG = -3

G (4/3, -3)

b)

xM = 2 + 4 /2

xM = 3

yM = ((-1)) + (-3))/2

yM = -2

M = (3,-2)
