Answer: C
Step-by-step explanation: Hope this help :D
Result
You entered the following points:
<span>A = <span>(<span> 1 , 2 </span>)</span></span>
<span>B = <span>(<span> −9 , 3 </span>)</span></span>
<span>The distance between points A
and B
is :</span>
<span>d(A,B)=<span>101<span>−−−</span>√</span> ≈ 10.0499</span>
Explanation
To find distance between points <span>A(<span>xA</span>,<span>yA</span>)</span>
and <span>B(<span>xB</span>,<span>yB</span>)</span>
, we use formula:
<span>d(A,B)=<span><span>(<span>xB</span>−<span>xA</span><span>)2</span>+(<span>yB</span>−<span>yA</span><span>)2</span></span><span>−−−−−−−−−−−−−−−−−−−</span>√</span></span>
In this example: <span><span>xA</span>=1</span>
, <span><span>yA</span>=2</span>
, <span><span>xB</span>=−9</span>
and <span><span>yB</span>=3</span>
so:
<span><span><span>d(A,B)</span><span>d(A,B)</span><span>d(A,B)</span></span><span><span>=<span><span><span><span>(<span>−9−1</span>)</span>2</span>+<span><span>(<span>3−2</span>)</span>2</span></span><span>−−−−−−−−−−−−−−−−</span>√</span></span><span>=<span><span>100+1</span><span>−−−−−−</span>√</span></span><span>=<span>101<span>−−−</span><span>√</span></span></span></span></span>
