Question

What is the magnitude of the vector a = (-3,5)?

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

a = ( -3 , 5)

Step 02:

magnitude of the vector:

$|a|\text{ = }\sqrt[]{x^2+y^2}=\sqrt[]{(-3)^2+5^2}=\sqrt[]{9+25}=\sqrt[]{34}$

|a| = 5.83

The answer is:

|a| = 5.83
