What is the center and radius of the circle 100x2 plus 100y2 -120x plus 100y -39 equals 0?

If you mean circle equation: 100x^2 +100y^2 -120x +100y -39 = 0
Then divide all terms by 100: x^2 +y^2 -6/5x +y -39/100 = 0
Completing the squares: (x-3/5)^2 +(y+1/2)^2 = 1 which is radius squared
Center of circle: (3/5, -1/2)
Radius of circle: square root of 1 = 1 unit

What is 200 in Roman Numeral?
100 would be a C. 200 is 100x2, so 200 could also be Cx2. That would be two Cs, so that is CC. 200 is CC.It is: 200 = CC
What is the perimeter of 24cm by 100cm?
248cm. Why? Because it is a rectangle so the perimeter is length + length + width + width or just widthx2 + lengthx2. So, 24x2=48 and 100x2=200. 200+48=248cm.

What is the centre and radius of the circle whose equation is 100x2 plus 100y2 -120x plus 100y -39 equals 0?
A circle with centre (X, Y) and radius r has an equation of the form: (x - X)² + (y - Y)² = r² Equation of circle: 100x² + 100y² - 120x + 100y - 39 = 0 Divide all terms by 100: x² + y² - 1.2x + y - 0.39 = 0 Rearrange bringing x terms and y terms together: x² - 1.2x + y² + y - 0.39 = 0 Completing the squares: (x - 1.2/2)² - (1.2/2)² + (y + 1/2)² - (1/2)² - 0.39 = 0 Collect the numbers together on the right hand side: (x - 0.6)² - 0.6² + (y + 0.5)² - 0.5² - 0.39 = 0 (x - 0.6)² + (y + 0.5)² = 0.36 + 0.25 + 0.39 (x - 0.6)² + (y + 0.5)² = 1 = 1² Centre of circle: (0.6, -0.5) Radius of circle: 1

What is the centre and radius of the circle whose equation is 100x2 plus 100y2 -120x plus 100y -39 equals 0 on the Cartesian plane?
A circle with centre (X, Y) and radius r has an equation of the form: (x - X)² + (y - Y)² = r² Dividing through by 100, completing the square and rearranging gives: 100x² + 100y² - 120x + 100y - 39 = 0 → x² - (6/5)x + y² + y - 39/100 = 0 → (x - (6/10))² - (6/10)² +(y + 1/2)² - (1/2)² - 39/100 = 0 → (x - 3/5)² - 36/100 + (y + 1/2)² - 1/4 - 39/100 = 0 → (x - 3/5)² + (y + 1/2)² - 1/4 - 75/100 = 0 → (x - 3/5)² + (y + 1/2)² = 1/4 + 3/4 → (x - 3/5)² + (y - (-1/2))² = 1 = 1² → Circle has centre (3/5, -1/2) = (0.6, -0.5) and radius 1.
