Question 1

Find the centre and radius of the circle having the equation  x2 + y2 - 12x + 20y + 15 = 0.
◦ centre (6, 10) and radius
◦ centre (-6, 10) and radius  15
◦ centre (6, -10) and radius  121
◦ centre (6, -10) and radius  11
◦ centre (12, -20) and radius  15

Question 2

Describe the region defined by the pair of inequalities  x2 + y2  ≤  9  and  x2 + (y + 3)2  ≤  6.
◦ all points that are inside or on both the circle of radius 3 centred at the origin and the circle of radius centred at (3, 0)
◦ all points that are inside or on both the circle of radius 3 centred at the origin and the circle of radius centred at (-3, 0)
◦ all points that are inside or on both the circle of radius 3 centred at the origin and the circle of radius centred at (0, -3)
◦ all points that are inside or on both the circle of radius 9 centred at the origin and the circle of radius 6 centred at (0, -3)
◦ all points that are inside or on both the circle of radius 3 centred at the origin and the circle of radius centred at (0, 3)
