Any vector in the xy-plane has the form v = c1i + c2j + 0k
For v to be perpendicular to a, we need v · a = 0
So, 3c1 - 5c2 = 0
For example, choose c1 = 5 and c2 = 3.
Then v = 5i + 3j + 0k is perpendicular to a.
ll v ll = √[52 + 32 + 02] = √34
A unit vector in the xy-plane that is perpendicular to 3i - 5j + k is:
u = v / llvll = (5/√34)i + (3/√34)j + 0k
Answer:
The simile helps the reader understand King Arthur's pain.
Explanation:
A simile is an explicit comparison between two things of a different kind, in order to make a description more intense. It uses the words "as," "like," and verbs similar to "resemble."
In the excerpt from "Morte d'Arthur,” by Alfred Lord Tennyson, King Arthur is disappointed with Sir Bedivere because Arthur has ordered him twice to throw Excalibur into the lake and Sir Bedivere has failed to do so.
