Conics

What are the coordinates of the center and the radius of the circle with equation:
(x - 4)² + (y - 3)² = 25 ?

• Center (4,3)
  Radius = 5 units

• Center (4,3)
  Radius = 25 units

• Center (-4,-3)
  Radius = 25 units

• Center (-4,-3)
  Radius = 5 units

Find the equation of the figure shown.

• (x-5)² + (y-3)² = 25

• (x+5)²/4 + (y+3)²/9 = 1

• (x-5)²/2 + (y-3)²/3 = 1

• (x-5)²/4 + (y-3)²/9 = 1

Find the equation of the figure shown.

• (x-1)²/16 - (y+2)²/4 = 1

• (x+1)²/16 - (y-2)²/4 = 1

• (y+2)²/4 - (x-1)²/16 = 1

• (x-1)²/4 - (y+2)²/2 = 1
