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)

Did you know?

Blastomycosis is often misdiagnosed, resulting in tragic outcomes. It is caused by a fungus living in moist soil, in wooded areas of the United States and Canada. If inhaled, the fungus can cause mild breathing problems that may worsen and cause serious illness and even death.

Did you know?

People with alcoholism are at a much greater risk of malnutrition than are other people and usually exhibit low levels of most vitamins (especially folic acid). This is because alcohol often takes the place of 50% of their daily intake of calories, with little nutritional value contained in it.

Did you know?

As many as 20% of Americans have been infected by the fungus known as Histoplasmosis. While most people are asymptomatic or only have slight symptoms, infection can progress to a rapid and potentially fatal superinfection.

Did you know?

The senior population grows every year. Seniors older than 65 years of age now comprise more than 13% of the total population. However, women outlive men. In the 85-and-over age group, there are only 45 men to every 100 women.

Did you know?

For about 100 years, scientists thought that peptic ulcers were caused by stress, spicy food, and alcohol. Later, researchers added stomach acid to the list of causes and began treating ulcers with antacids. Now it is known that peptic ulcers are predominantly caused by Helicobacter pylori, a spiral-shaped bacterium that normally exist in the stomach.
