Question

A vector in standard position has its terminal point at (7, –4). what is the magnitude of the vector? startroot 3 endroot 3 startroot 65 endroot 65

Answer 1

Answer:

  (c)  √65

Step-by-step explanation:

You want to know the magnitude of the vector (7, -4).

Vector magnitude

The magnitude of a vector is the root of the sum of the squares of its components.

  |(7, -4)| = √(7² +(-4)²) = √(49 +16) = √65

The magnitude of the vector is √65.
