Question

Vector v is plotted below. What is the length of the x-component of v?

A. 3
B. 4
C. 1
D. 2

Answer 1

Answer:

C. 1

Explanation:

We can see that each box in the grid is one unit.

We count one box to the right on the horizontal axis and 4 boxes down on the vertical axes to obtain the components of vector v.

See graph in attachment.

Therefore the components of vector v is


`\binom{1}{-4}`.

The length of the x component is 1 unit

Hence the correct answer is C.
