Typically, the equation of a circle is given like this: (x-h)^2 + (y-k)^2 = r^2, where r is the radius of the circle and the point (h,k) is the center. To find the value k, you need to put the first equation you have into this form. Standard form requires that you only have the1 y variable, as seen in the parentheses, so you first need to complete the square.
x^2 + y^2 - 2y = 11
x^2 + y^2 - 2y +1 = 11 + 1
x^2 + (y - 1)^2 = 12
And that puts the equation in standard form. k = 1.
Multiply by 12. The answer is 105in.
Answer:
y-1=-2/3(x-5)
Step-by-step explanation: You have to use slope formula to find the slope, Then you use the first set of points because it have to be x1
The answer is:
Square root of 77
—————————
22
You need to rationalize the denominator meaning that you have to get rid of the square root signs in denominator
To get rationalize the denominator you need to multiply both sides by square root of 11
(Square root of 7)(square root of 11)
——————————————————
2(square root of 11)^2
When squaring a square root it makes the square root “go away”
(Square root of 77)
——————————
2(square root of 11^2 or 122) = 2(11)
So:
The answer is
square root of 77
—————————
22
