Quizplus · Accepted Answer

The magnitude of vector $\mathbf{v} = \langle 3, 0, 8 \rangle$ is calculated as $\sqrt{3^2 + 0^2 + 8^2} = \sqrt{9 + 0 + 64} = \sqrt{73}$. However, none of the options match this calculation, so it seems there might be a misunderstanding in the question or options provided.
