Step 1: First, find the vector addition of $\vec{\mu}$ and $2\vec{\pi}$.
\vec{\mu} + 2\vec{\pi} = \{4,-1\} + 2\{3,3\}
To do this, add the corresponding components of the vectors.
Step 2: This simplifies to:
\vec{\mu} + 2\vec{\pi} = \{4,-1\} + \{6,6\}
Final Answer
B. 11 (with the understanding that this is an approximation)
