Precalculus :Ellipse and circle

What is the center of the ellipse?

• (0, 0)
• (1, 5)
• (1, 0)
• (0, 1)

Identify the center and the length of a and b.

• C: (0,4)  a= 25, b=4
• C: (0,0)  a= 4, b=25
• C: (0,5)  a= 2, b=5
• C: (0,0)  a= 5, b=2

Given the following, write the equation of the ellipse.

• Not the answer

• THIS IS THE CORRECT ANSWER

• Co-Vertices

What are the foci of the shifted ellipse?

• (-5,1) and (-1,1)
• (±√3,0)
• (0,1) and (-6,1)
• (√3 - 3,1) and (-√3 - 3,1)

What is the length of the MINOR axis?

• 12

• 14

• 49

• 36

What are the coordinates of the FOCUS points?

• ( 13 , 5 ) and ( - 1 , 5 )

• ( 6 , 11 ) and ( 6 , - 1 )

• ( 9.6 , 5 ) and ( 2.4 , 5 )

• ( 19 , 5 ) and ( - 7 , 5 )

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
