The Dot Product
For two-dimensional vectors $\vec{a}$ and $\vec{b},$ if $\|\vec{a}\|=2$ and $\|\vec{b}\|=4,$ find $\|\vec{a}+\vec{b}\|$ for the given $\vec{a} \cdot \vec{b}$ $$\vec{a} \cdot \vec{b}=0$$
A Fundamental Tool: Vectors
The vectors $\vec{a}, \vec{b},$ and $\vec{c}$ are such that $\vec{a}+\vec{b}+\vec{c}=\overrightarrow{0}$. Determine the value of $\vec{a} \cdot \vec{b}+\vec{a} \cdot \vec{c}+\vec{b} \cdot \vec{c}$ if $|\vec{a}|=1,|\vec{b}|=2,$ and $|\vec{c}|=3$
