Find the center and radius of the circle whose equation is x^ (2) + y ^(2) - 6x - 2y + 4 = 0

Step-by-step explanation:

The center of a circle can be found using the equation and is (h,k) from it. Notice h and k are the opposite value as in the equation.

First write the equation in this form.

Complete the square with each variable to find what numbers should go in place of the question marks.

Add 1 and 9 to both sides of the equation.

So the center is (3,1) and the radius is √6.

the answer is 31.27mph

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
