Find the coordinates of the vectors \( \vec{u} \) and \( \vec{v} \) given by the picture and evaluate their dot product.
\( \vec{u}=(-8,-7,9),\ \ \vec{v} =(8,7,9),\ \ \vec{u}\cdot\vec{v} = -32 \)
\( \vec{u}=(-8,-7,9),\ \ \vec{v} =(8,7,9),\ \ \vec{u}\cdot\vec{v} = 0 \)
\( \vec{u}=(-8,-7,9),\ \ \vec{v} =(8,7,9),\ \ \vec{u}\cdot\vec{v} = (-64,-49,81) \)
\( \vec{u}=(8,7,-9),\ \ \vec{v} =(-8,-7,-9),\ \ \vec{u}\cdot\vec{v} = (-64,-49,81) \)
