Solve.Two radio transmitters are located 350 miles apart on a shore and send simultaneous signals to a ship that is 175 miles offshore. The signal from transmitter T arrives at the ship 400 microseconds after the signal from transmitter S. The signals travel at the speed of 0.186 miles per microsecond. Find the equation of the hyperbola with foci S and T on which the ship is located. Let the center point between the transmitters correspond to the point (0, 0) and let the x-axis be oriented such that it contains the two transmitters. (Hint: For any point along the hyperbola, the absolute value of the difference of its distances from the foci is 2a.)

Use the following information to solve the problem. An airport is located at point O. A short-range radar tower is located at point R. The maximum range at which the radar can detect a plane is 4 miles from point R.Assume that R is 5 miles east of O and 7 miles north of O. In other words, R is located at the point 
. An airplane is flying parallel to and 4 miles east of the north axis. (In other words, the plane is flying along the path 
.) What is the greatest distance north of the airport at which the plane can still be detected by the radar tower at R? Round your
answer to the nearest tenth of a mile. A. 9.2 miles B. 10.9 miles C. 10 miles D. 3.1 miles
