At least one of the answers above is NOT correct.

$1$ of the questions remains unanswered.

Suppose $\frac{?}{\text{b}\text{a}\text{r}}(u)=($:$3,5,2$:$)$ and $\frac{?}{\text{b}\text{a}\text{r}}(v)=($:$0,2,5$:$).$ Then:

The projection of $\frac{?}{\text{b}\text{a}\text{r}}(u)$ along $\frac{?}{\text{b}\text{a}\text{r}}(v)$ is

The projection of $\frac{?}{\text{b}\text{a}\text{r}}(u)$ orthogonal to $\frac{?}{\text{b}\text{a}\text{r}}(v)$ is $$
