Consider the following vectors.
u = (-7, 15), v = \left(-\frac{5}{7}, \frac{1}{3}\right)
Find the dot product of the two vectors.
\mathbf{u} \cdot \mathbf{v} = 0
Find a scalar value $c$ such that $\mathbf{u} = c\mathbf{v}$. (If such a value does not exist, enter DNE.)
c = DNE
Determine whether \mathbf{u} and \mathbf{v} are orthogonal, parallel, or neither.
$\circ$ orthogonal
$\circ$ parallel
$\circ$ neither
