Question

Find 1/3u, if u=(1, -3)
(1, -1)
(1/3, -1)
(3, -9)
(1, -9)

Answer 1

1/3, -1

Explanation:

Just finished the test

Answer 2

For this case we have the following vector:
u = (1, -3)
When multiplying by the scalar 1/3 we have:
1 / 3u = (1/3) (1, -3)
Rewriting the new vector we have:
1 / 3u = (1/3, -3/3)
1 / 3u = (1/3, -1)
Answer:
1 / 3u = (1/3, -1)
