Question

What is the vector from (2,–6,4) to (1,2,7) ?​

Answer 1

Answer:

1. i-8j+3k 2. I+8j-3k 3. -i+8j+3k 4.-i-8j+3k

Answer 2

Answer:

$(-\^{i} +8\^{j} +3\^{k})$ is the vector from of (2,-6,4)to (1,2,7)

Step-by-step explanation:

Explanation:

Given ,  (2,-6,4) to  (1,2,7)

Let $\vec{OA}$ = $2\^{i} -6\^{j} +4\^{k}$ and

let $\vec{OB}$ = $\^{i} +2\^{j} +7\^{k}$

Step 1:

Vector from A to B

$\vec{AB} = \vec{OB} - \vec{OA}$

⇒$\vec{AB} =$( $\^{i} +2\^{j} +7\^{k}$ ) - $(2\^{i} -6\^{j} +4\^{k})$

⇒$\vec{AB}$= ($-\^{i} +8\^{j} +3\^{k}$).

Final answer :

Hence , the vector from (2,-6,4) to (1,2,7) is ($-\^{i} +8\^{j} +3\^{k}$).
