The components of vectors Q and R are (-3.0, 5.5) and (9.2, 4.4) respectively. Determine the components of Q + R.
Put the vectors in their component forms
Q( -3.0i, 5.5j) and P(9.2i, 4.4j)
Q + P = -3.0i, 5.5j + 9.2i, 4.4j = ( - 3.0 + 9.2)i + ( 5.5 + 4.4)j = ( 6.2i + 9.9j)
therefore Q + P = (6.2 , 9.9).
