Which is the equation of the circle?

Mathematics
1 answer:
Shkiper50 [21]3 years ago
5 0
Equation of a circle is given by:
(x-a)²+(y-b)²=r²
where (a,b) is the center of the circle and r is the radius. From the graph;
(a,b)=(-1,2) and r=7
thus plugging the values in the equation we get:
(x--1)²+(y-2)²=7²
simplifying the above we get:
(x+1)²+(y-2)²=49
hence we conclude that the answer is:
B](x+1)²+(y-2)²=49

Write a subtraction fact with the same difference as 16-7?
Alona [7]
So, this is asking for any number that subtracts to = 16-7

Well, 16-7= 9 so use any two numbers that would subtract to equal 9

Like so:

11-2=9
18-9=9
34-25=9
-2-11=9
Etc....

Hope this helps! :)

What is the area of a regular hexagon (6 sides) whose
Ganezh [65]

Step-by-step explanation:

With reference to the regular hexagon, from the image above we can see that it is formed by six triangles whose sides are two circle's radii and the hexagon's side. The angle of each of these triangles' vertex that is in the circle center is equal to 360∘6=60∘ and so must be the two other angles formed with the triangle's base to each one of the radii: so these triangles are equilateral.

The apothem divides equally each one of the equilateral triangles in two right triangles whose sides are circle's radius, apothem and half of the hexagon's side. Since the apothem forms a right angle with the hexagon's side and since the hexagon's side forms 60∘ with a circle's radius with an endpoint in common with the hexagon's side, we can determine the side in this fashion:

tan60∘=opposed cathetusadjacent cathetus => √3=Apothemside2 => side=(2√3)Apothem

As already mentioned the area of the regular hexagon is formed by the area of 6 equilateral triangles (for each of these triangle's the base is a hexagon's side and the apothem functions as height) or:

Shexagon=6⋅S△=6(base)(height)2=3(2√3)Apothem⋅Apothem=(6√3)(Apothem)2

=> Shexagon=6×62√3=216

What are compatible number of 7233 divided by 84
valkas [14]
To me, do the math using compatible number, means to estimate
7233 can round to 8000
and 84 can round to 80
now, this makes it easy, you can do it mentally, which is 100

In more detailed, 
7233 can round to 7225
and 84 can round to 85
then, (not so obvious, but however) 85 times 85 equal 7225

so the compatible number of 7233 divided by 84, is 7225 and 85

I know it's a bit late, but hope it helps
