![This educational exercise involves finding specific vector operations. We're given two vectors:
\[ \mathbf{u} = (2, 12) \]
\[ \mathbf{v} = (-3, 2) \]
We are tasked with calculating the following:
(a) **\( \mathbf{u} \cdot \mathbf{v} \)**: The dot product between vectors \(\mathbf{u}\) and \(\mathbf{v}\).
(b) **\( \mathbf{u} \cdot \mathbf{u} \)**: The dot product of vector \(\mathbf{u}\) with itself.
(c) **\(\|\mathbf{v}\|^2 \)**: The square of the magnitude of vector \(\mathbf{v}\).
(d) **\((\mathbf{u} \cdot \mathbf{v}) \mathbf{v}\)**: The scalar multiplication of vector \(\mathbf{v}\) by the dot product of \(\mathbf{u}\) and \(\mathbf{v}\).
(e) **\(\mathbf{u} \cdot (3\mathbf{v})\)**: The dot product of vector \(\mathbf{u}\) with vector \(\mathbf{v}\) scaled by 3.
This exercise involves basic operations like dot products and scalar multiplications, which are fundamental in vector algebra.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff1c2b75e-6fee-4f9b-af7a-a18971ffe565%2F0385c9a6-ff31-46f5-940d-b272133d3356%2Foq439bb_processed.png&w=3840&q=75)
