Q. Question 7 *1 pointGiven that a=(23),∣a∣=(13)5134
Use Vector Magnitude Formula: First, we need to use the formula for the magnitude of a vector, which is ∣a∣=a12+a22 where a1 and a2 are the components of vector a. So, we plug in the values from vector a=([2],[3]) into the formula. This gives us ∣a∣=22+32.
Plug in Values: Now, we calculate the squares of the components.This gives us ∣a∣=4+9.
Calculate Squares: Next, we add the squares together.This gives us ∣a∣=13.
Add Squares: So, the magnitude of vector a is 13, which is one of the options given.
