Question

If u=<-3,0> and z=<-6,-4> what is the value of u.a

Answer 1

Answer:

18

Explanation:

Vectors u and z are defined below:

$\begin{gathered} u=<-3,0> \\ z=<-6,-4> \end{gathered}$

The dot product of u and z is evaluated below:

$\begin{gathered} u\cdot z=(-3\times-6)+(0\times-4) \\ =18+0 \\ \implies u\cdot z=18 \end{gathered}$

The dot product is 18.
