Question:** An angel investor is analyzing the growth patterns of a biotechnology startup. The growth rate of their revenue, modeled as a vector \(\mathbfr = \beginbmatrix 2 \\ 3 \\ 6 \endbmatrix\), needs to be decomposed into components parallel and perpendicular to the vector \(\mathbfa = \beginbmatrix 1 \\ 1 \\ 1 \endbmatrix\). Find the component of \(\mathbfr\) that is parallel to \(\mathbfa\). - Portal da Acústica
