Vector á = zi+j+zk Vector 6 = i +2j-k áxb-7i-9j-11k Calculate the values of z and z

Let be the vector with initial point (4, 7) and terminal point (8,4). Express as a linear combination of the standard unit vectors. Ov=-3i+47 Ov=-4i +37 Ov=41-37 Ov=4i +3j Ov=-41-3j O None of the above.

Part B

Let be the vector with initial point (8, 1) and terminal point (6,5). Express as a linear combination of the standard unit vectors. Ov=4i-2j 05-21-47 Ov=2i+4j Ov=-21-4j Ov=-2+47 O None of the above.

Which of these vectors is equivalent to the vector that has initial point (5,-2) and terminal point (3,1)? O O O O
