Question:** An angel investor is analyzing the growth patterns of a biotechnology startup. The growth rate of their revenue, modeled as a vector \(\mathbf{r} = \begin{bmatrix} 2 \\ 3 \\ 6 \end{bmatrix}\), needs to be decomposed into components parallel and perpendicular to the vector \(\mathbf{a} = \begin{bmatrix} 1 \\ 1 \\ 1 \end{bmatrix}\). Find the component of \(\mathbf{r}\) that is parallel to \(\mathbf{a}\).
