Vector $\vec{V_1}$ points along the z axis and has magnitude $V_1 = 78$. Vector $\vec{V_2}$ lies in the xz plane, has magnitude $V_2 = 56$, and makes a -50° angle with the x axis (points below x axis).
What is the scalar product $\vec{V_1} \cdot \vec{V_2}$?
Express your answer using two significant figures.
$\vec{V_1} \cdot \vec{V_2} =$
