Step-by-step explanation:
Using scalar multiplication, it is found that 5u = <10,20>.
<h3>What is scalar multiplication?</h3>
- It is when a vector is multiplied by a constant, and it means that each term of the vector is multiplied by the constant.
In this problem, the vector is:
u = <2,4>
Since each term is multiplied by 5:
5u = <5 x 2, 5 x 4> = <10,20>.
