Answer to Problem 30E

  (x3)2+(y+5)2=169r=13Center(3,5)

Explanation of Solution

Given information: The coordinates (2,7),(9,0),(10,5)

Calculation:

Points (x,y):(2,7),(9,0),(10,5)

Plug in the 3 points to create 3 equations which we can use to solve the system to find all of the missing values.

Remember the form:

  (xh)2+(yk)2=r2Vertex at:(h,k)

  Pt:(2,7):(2h)2+(7k)2=r2h2+k2+4h14k+53=r2Pt:(9,0):(9h)2+(0k)2=r2h2+k2+18h+81=r2Pt:(10,5):(10h)2+(5k)2=r2h2+k2+20h+10k+125=r2

Set 1st 2 equations equal to each other: because they both equal r2 .

  h2+k2+4h14k+53=h2+k2+18h+81h=k2

Set the 1st and 3rd equations equal: because they also both equal r2 .

  h2+k2+4h14k+53=h2+k2+20h+10k+12516h=24k72h=3k92

Set these 2 results equal because they both equal r2

  k2=3k92k=5

  If k=5 then h=3

You know the center (h,k)=(3,5)

Plug these values for h and k into any of the equations to find r .

  (3)2+(5)2+4(3)14(5)+53=r2r2=169

Standard form:

  (x3)2+(y+5)2=169r=13Center(3,5)
