A pair of radar stations monitors the path of a helicopter. Station A is located at the origin of a coordinate plane. Station B is located 100 miles east of station A. The difference in the distances from the helicopter to each station is 60 miles. Which equation represents the possible locations of the helicopter?
Answer
A
StartFraction (x minus 50) squared Over 900 EndFraction minus StartFraction y squared Over 1,600 EndFraction = 1
B
StartFraction (x minus 50) squared Over 3,600 EndFraction minus StartFraction y squared Over 6,400 EndFraction = 1
C
StartFraction (x minus 100) squared Over 900 EndFraction minus StartFraction y squared Over 1,600 EndFraction = 1
D
StartFraction (x minus 100) squared Over 3,600 EndFraction minus StartFraction y squared Over 6,400 EndFraction = 1
