Question

Determine o vetor resultante da operação z=2.(2,7,-4)-(1,1,1)+3.(2,0,0).

Answer 1

Resposta:

z = (9, 13, -9)

Explicação passo a passo:

z = 2.(2, 7, -4) - (1, 1, 1) + 3.(2, 0, 0)

z = (4, 14, -8) - (1, 1, 1) + (6, 0, 0)

z = (4-1+6, 14-1+0, -8-1+0)

z = (9, 13, -9)

Answer 2

Vamos là.

z=2.(2,7,-4)-(1,1,1)+3.(2,0,0).

z = (4, 14, -8) -(1, 1, 1) + (6, 0, 0)

z = (4 - 1 + 6) (14 - 1 + 0) (-8 - 1 + 0)

z = (9, 13, -9)
