Math Problem Statement

  1. Find the intercepts of the following algebraically, show your work. (check in your calculator if you want some extra practice) You may do these on this sheet if you prefer. (x − 3)^2 + (y − 6)^2 = 58

Solution

To find the intercepts of the given equation (x3)2+(y6)2=58(x - 3)^2 + (y - 6)^2 = 58, we'll solve for both the x-intercepts and y-intercepts separately.

Finding the x-intercepts:

For x-intercepts, we set y=0y = 0 and solve for xx.

Substitute y=0y = 0 into the equation: (x3)2+(06)2=58(x - 3)^2 + (0 - 6)^2 = 58

Simplify: (x3)2+36=58(x - 3)^2 + 36 = 58

Subtract 36 from both sides: (x3)2=22(x - 3)^2 = 22

Take the square root of both sides: x3=±22x - 3 = \pm \sqrt{22}

Solve for xx: x=3±22x = 3 \pm \sqrt{22}

Thus, the x-intercepts are: x=3+22andx=322x = 3 + \sqrt{22} \quad \text{and} \quad x = 3 - \sqrt{22}

Finding the y-intercepts:

For y-intercepts, we set x=0x = 0 and solve for yy.

Substitute x=0x = 0 into the equation: (03)2+(y6)2=58(0 - 3)^2 + (y - 6)^2 = 58

Simplify: 9+(y6)2=589 + (y - 6)^2 = 58

Subtract 9 from both sides: (y6)2=49(y - 6)^2 = 49

Take the square root of both sides: y6=±7y - 6 = \pm 7

Solve for yy: y=6+7ory=67y = 6 + 7 \quad \text{or} \quad y = 6 - 7

Thus, the y-intercepts are: y=13andy=1y = 13 \quad \text{and} \quad y = -1

Summary of Intercepts:

  • x-intercepts: x=3+22x = 3 + \sqrt{22} and x=322x = 3 - \sqrt{22}
  • y-intercepts: y=13y = 13 and y=1y = -1
