PART C: THINKING AND INQUIRY 5. A vector # has its tail at the point (5, -6) and its tip at the point (-2, -1). Express the vector in algebraic (component) form and draw the corresponding position vector on the given axes. [2 marks] -j...... . .7 -6_ 6. Given vectors a and b such that the angle between the two vectors is 60, | a | = 3, and | b | = 2, determine | a + b |. [4 marks] 7. Find the components of the unit vector, w, in the opposite direction to that of XY where X(5, 4, -1) and Y(3, 1, 2). [3 marks]
