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