Question

Find the dot product u • v between two vectors u = 8i + 5j and v = –3i – 2j.

Answer 1

Answer:

$-34$

Explanation:

Here, we want to get the dot product of the two vectors

What we have to do here is to multiply the coefficient of the terms and sum up

We have that as:

$\begin{gathered} u\text{ . V = 8\lparen-3\rparen + \lparen5\rparen\lparen-2\rparen } \\ =\text{ -24 -10 = -34} \end{gathered}$
