Question

What is the column vector represented by arrow 'b'?

Answer 1

Answer:

$\binom{4}{0}$

Step-by-step explanation:

A column vector is shown in the form $\binom{x}{y}$ where x is how many spaces to move in the positive x direction y is how many spaces move in the positive y direction.

The vector b moves 4 spaces to the right (which is in the positive direction of x) and doesn't move up or down in the y direction which is 0, so the column vector is $\binom{4}{0}$
