Hello all, i need some help with these questions. I didn't have any clue on how to approach these so an explanation would be appreciated.
1.) O, A and B are the points (0,0), (3,4) and (4,-6) respectively.
a.) C is the point such that OA = OC + OB. Find the coordinates of C
b.) D is the point (1,24) and OD = hOA + kOB. Find the values of h and k.
2.) If a = 5i - sj + 2k and b = ti + 2j + uk are equal vectors, find
a.) i.) s
iv.) Magnitude of a
