Answer:
4
Step-by-step explanation:
Given the following column vectors
(1, -2, 0), (-1, 3, 1), (2, 1, 5) and (-1, 1, 1)
Before we can get the dimension of the vector, the following steps must be followed;
Step 1:
We need to transform the vectors given into a matrix form and then reduce the resulting matrix.
Step 2:
Then we generated the basis of the matrix (new set of column vectors from the reduced matrix).
Step3:
The total number of column vectors generated will be equivalent to the dimension of the vectors.
The dimension spanned by the set of vectors is 4
