Answer:

Equation of the circle is

(x-4)^2+y^2=12

Step-by-step explanation:

We have been given that

center of the circle = (4,0)

Radius of the circle = 2\sqrt3

The standard form of a circle is given by

(x-h)^2+(y-k)^2=r^2

Here, (h,k) is the center and r is the radius. Thus, we have

h = 4, k = 0, r = 2√(3)

Substituting these values in the above equation, we get

(x-4)^2+(y-0)^2=(2\sqrt3)^2

Simplifying, we get

(x-4)^2+y^2=12

Therefore, equation of the circle is

(x-4)^2+y^2=12

Find the area of the shaded region to the nearest tenth. See picture for full problem. Please and thank you so much!
Anestetic [448]

Answer:

Step-by-step explanation:

Radius =6 ft

Area of circle = πr²

                      = 3.14 * 6 * 6

                      = 113.04 ft²

base = 10.39 ft

height = 6+3 = 9 ft

Area \ of \ triangle = \dfrac{1}{2}*base * height\\\\\\=\dfrac{1}{2}*10.39*9\\

= 46.76 ft²

Area of the shaded region = area of circle - area of triangle

             = 113.04 - 46.76

            = 66.28

             = 66.3 ft²

Solve each system by elimination<br><br> 5x+y=9<br> 10x-7y=-18<br><br> -4x+9y=9<br> x-3y=-6
tiny-mole [99]
5x + y = 9....multiply by 7
10x - 7y = -18
----------------
35x + 7y = 63 (result of multiplying by 7)
10x - 7y = -18
----------------add
45x = 45
x = 45/45
x = 1

5x + y = 9
5(1) + y = 9
5 + y = 9
y = 9 - 5
y = 4

solution is : (1,4)
=========================
-4x + 9y = 9
x - 3y = -6 ....multiply by 4
----------------
-4x + 9y = 9
4x - 12y = -24 (result of multiplying by 4)
---------------add
- 3y = - 15
y = -15/-3
y = 5

x - 3y = -6
x - 3(5) = -6
x - 15 = -6
x = -6 + 15
x = 9

solution is : (9,5)

six friends share 5 meat pies. each friend first eats half of a meat pie. how much more meat pie does each friend need to eat to
Margaret [11]
So at the beginning, the friends eat 3 meat pies in total. So that leaves two meat pies left. 
So basically, we divide the meat pies by the number of friends.
2/6 is 1/3
So each friend needs to eat 1/3 of a meat pie
