Find the dot product, \( \vec{u} \cdot \vec{w} \).
\[
\begin{array}{l}
\vec{u}=\langle-7,-4\rangle \\
\vec{w}=\langle 4,-3\rangle
\end{array}
\]
\[
\vec{u} \cdot \vec{w}=[?]
\]
\( \vec{u} \cdot \vec{w} = -16 \)
Step 1 :\( \vec{u} \cdot \vec{w} = (-7)(4) + (-4)(-3) \)
Step 2 :\( \vec{u} \cdot \vec{w} = -28 + 12 \)
Step 3 :\( \vec{u} \cdot \vec{w} = -16 \)
