Vector and scalar resolutes

Consider the vectors $\tvec{r}$ and $\tvec{s}$ where $|\tvec{r}| = 9$ and $\tvec{s} = 2\tvec{i} - 2\tvec{j} + \tvec{k}$.

If the vector resolute of $\tvec{r}$ in the direction of $\tvec{s}$ is equal to $-4\tvec{i} + 4\tvec{j} - 2\tvec{k}$, then the scalar resolute of $\tvec{s}$ in the direction of $\tvec{r}$ is equal to
