A circle passes through the point (0,1), and is tangent to the parabola y = x^2 at (2,4). Find the center of the circle. 

 

The answer should be in the form (a,b), the answer should be a fraction not decimal. smiley

Find the center of the circle.

 

Hello proyaop!

 

f(x)=x2dydx=2x=22=4mg=14 | Pg(2,4)g(x)=14(x2)+4g(x)=14x+92

h(x)=4120x+1h(x)=32x+1

mi=23 | Pi(1,2.5)i(x)=23(x1)+52i(x)=23x+196

i(x)=g(x)23x+196=14x+92512x=86

xC=165

y=14x+92y=14(165)+92yC=5310

 

The center of the circle is PC(165,5310)

laugh  !
