This is Calculus course especially about vectors. I need help with some questions. I also attached formula sheet in case you need it as a reference.

Section 1: Chapter 6 Questions 1. Indicate whether the following are scalars or vectors.[5 marks] a) 40 km/h b) 10 km Northwest c) downward force of 12 N_ d) distance of the moon from Earth e) 100 km/h on a bearing of 230 2. List as many equal vectors as possible for each diagram.[2 marks] E 3. Draw 3u - 2v to scale (use a ruler) using the vectors u and v below. [2 marks] 4. ABCD is a rectangle where AB = a and AD = b . Draw a diagram to compare la + 5 and a - b . [2 marks] 5. If u = [-1, -1], v = [2, 6], and w = [-11, -8], express w as a linear combination of u and v . [2 marks]Formulas: a . b = lal|b|cose |axb = lallb|sine a a = lal scalar proja onto b = lalcose vector proja onto b = lalcose W = |d| |F|cose IT| = 171/F/sine Area of a paralellogram = lax b|
