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

The length of the x-component of v is 2

Explanation:

Vectors in Two Dimensions

A vector in the plane can be represented as its two components in the rectangular coordinates (x,y), assuming its initial point is the origin (0,0).

The vector plotted in the image provided has the components (-2,5).

The x-component is -2 and the y-component is 5.

The length of the component is the magnitude or absolute value of the x-coordinate, thus the length of the x-component of v is 2
