# Two radio transmitters positioned 200200 mi apart along the shore send simultaneous signals to a ship

Two radio transmitters positioned 200200 mi apart along the shore send simultaneous signals to a ship that is 100100 mi offshore and sailing parallel to the shoreline. The signal from transmitter S reaches the ship 500500 microseconds later than the signal from transmitter T. The signals travel at a speed of​ 186,000 miles per​ second, or 0.186 mile per microsecond. Find the equation of the hyperbola with foci S and T on which the ship is located.​ (Hint: For any point on the​ hyperbola, the absolute value of the difference of its distances from the foci is​ 2a.)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
