Danielle Morales · Answer 1

For Part A.

The absolute value of vector A is

|A | = 6

This is simply the square root of the sum of the squares of the coordinates.

For Part B

Do the same thing as in Part A

| B | = √14

Part C

Simply subtract the corresponding elements resulting in

(-3, 2, 7)

Part D

√62

Part E

Yes
