Chapter 3.5, Problem 4E

Let $E=\left[{\left(5,3\right)}^T,{\left(3,2\right)}^T\right]$ and let $\text{x}={\left(1,1\right)}^T$ , $\text{y}={\left(1,-1\right)}^T$ , and $\text{z}={\left(10,7\right)}^T$ . Determine the values of ${\left|\text{x}\right|}_E$ , ${\left|\text{y}\right|}_E$ , and ${\left|\text{z}\right|}_E$ .
