Can u please help me solve? I'm reviewing for finals.

Given:

Consider the given graph as a reference of the solution.

To find:

$-3(u\cdot v)$

Explanation:

By analyzing the graph, we can define the coordinate of vector u and v:

$\begin{align} & \vec{u}=(-8,-9)-(0,0)=(-8,-9) \\ & \vec{v}=(3,7)-(0,0)=(3,7)\end{align}$

Now, let perform the dot product of two vectors,

$\begin{gathered} u\cdot v=(-8,-9)\cdot(3,7) \\ u\cdot v=(-8)(3)+(-9)(7) \\ u\cdot v=-24-63 \\ u\cdot v=-87 \end{gathered}$

Now, perform the required operation,

$\begin{gathered} -3(u\cdot v) \\ =-3(-87) \\ =261 \end{gathered}$

Final answer:

Hence, the required solution is:

$-3(u\cdot v)=261$
