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 ,
• Radius = 5 units
• Centre = (0,0)
Finding distance between the two points :-
Here we can see that the distance of point from centre is less than the radius.
Hence the point lies within the circle .
note: 5≠20
also, if you multiply both sides of an inequality by a negative number, you flip te direction of the inequality sign
example: 3<5, multiply by -1, -3>-5
so given
-2<3
multiply both ides by -5 and fip sign
remember that (-)(-)=(-) and (+)(-)=(-)(+)=(-)
10>-15
4th option is answer
Answer:
1/12
Step-by-step explanation:
For this case we have by definition, that the total surface area of a regular pyramid with a square base is given by:
Where:
p: It is the perimeter of the base
S: It's the inclination
It is the area of the base
Substituting:
ANswer:
Option B
Given that the book value of the automobile that was purchased is 30,000 and is to be depreciated for 3 years using MACRS method of depreciation the value of the automobile at the end of the year is 8,640 dollars. This is computed by summing up the depreciation for the firswt 3 years which is equal to 71.2 per cent less 100 then it will be multiply to 30,000.
