Question 1

Solve the problem.

Find an equation of the line containing the centers of the two circles
x² + y² + 6x + 4y + 12 = 0

and
x² + y² - 2x + 10y + 22 = 0
◦ -3x + 4y + 17 = 0
◦ 3x - 4y + 17 = 0
◦ 3x + 4y + 17 = 0
◦ -7x + 2y + 17 = 0

Question 2

Solve the problem.

A wildlife researcher is monitoring a black bear that has a radio telemetry collar with a transmitting range of 18 miles. The researcher is in a research station with her receiver and tracking the bear's movements. If we put the origin of a coordinate system at the research station, what is the equation of all possible locations of the bear where the transmitter would be at its maximum range?
◦ x² - y² = 18
◦ x² + y² = 324
◦ x² + y² = 18
◦ x² + y² = 36
