Part 2: Communication [17 marks] 4. The diagram is a rectangular prism. Let u = AB, v = AD and w = AE. Express each vector as a linear combination of u, u and w. [1 mark each] a) EF = b) HB = m H Completion [1 mark each] Complete each statement. 5. The addition of two vectors always results in another 6. A vector can be resolved into two vectors whose sum is the given vector. 7. An equilibrant vector is the opposite of the 8. The magnitude of vector [a, b, c] is 9. The magnitudes of vector [a, b, c] and vector [- a, - b, - c] are 10. If two vectors are orthogonal then their dot product equals Matching [1 mark each] MNPQ is a parallelogram and R is the intersection point of the diagonals MP and NQ. Let & = MQ and v = MN.
