Question 1
Solve the problem.
Find an equation of the line containing the centers of the two circles
x
2 + y
2 + 6x + 4y + 12 = 0
and
x
2 + y
2 - 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?
◦ x
2 - y
2 = 18
◦ x
2 + y
2 = 324
◦ x
2 + y
2 = 18
◦ x
2 + y
2 = 36
