Given equation of the Circle is ,
And we need to tell that whether the point (-4,2) lies inside or outside the circle. On converting the equation into Standard form and determinimg the centre of the circle as ,
Here we can say that ,
• <u>Radius</u> = 5 units
• <u>Centre </u> = (0,0)
<u>Finding</u><u> </u><u>distance</u><u> between</u><u> </u><u>the </u><u>two </u><u>points</u><u> </u><u>:</u><u>-</u><u> </u>
- Here we can see that the distance of point from centre is less than the radius.
<u>Hence </u><u>the</u><u> </u><u>point</u><u> </u><u>lies </u><u>within</u><u> </u><u>the </u><u>circle</u><u> </u><u>.</u>
Answer:
1,556,675,366,400
Step-by-step explanation:
There are 37 possible characters, of which 8 can be chosen. Order matters, so the number is ...
37P8 = 1,556,675,366,400
_____
This number includes 84,144,614,400 strings in which the space character is either first or last. Such strings may be ruled invalid because they are indistinguishable from 7-character strings.
_____
nPk = n!/(n-k)! . . . . the number of permutations of n things taken k at a time
The 37 allowed characters are the 26 letters of the alphabet, 10 digits, and 1 space character.
The answer is H, you cannot make such conclusion
