The question, in short

Given column vectors a = (4, 9), b = (−6, 1) and c = (13, −2), work out the vector results of the two operations.

Summarised in our own words. Use the official paper for the exact wording and any diagrams.

Part (a) · 1 mark

Find the sum of column vectors a and b.

  1. 1a + b = (4 + (−6), 9 + 1)
  2. 2= column vector (−2, 10)

Answercolumn vector (−2, 10)

Part (b) · 1 mark

Find the vector 3c, three times column vector c.

  1. 13c = (3 × 13, 3 × (−2))
  2. 2= column vector (39, −6)

Answercolumn vector (39, −6)
