Answer:

Step-by-step explanation:
TM = <u>m</u> - <u>t</u> ( <u>m</u> and <u>t</u> are position vectors )
= < - 1, 1, 2 > - < 3, - 5, 6 > ( subtract corresponding components )
= < - 1 - 3, 1 + 5, 2 - 6 >
= < - 4, 6, - 4 >
Given <u>v</u> = < x, y, z > then the magnitude of <u>v</u> is
| <u>v</u> | = , thus
| TM | =
= = = = 2
