At noon, ship A is 4D nautical miles due west of ship B. Ship A is sailing west at 18 knots and ship B is sailing north at 24 knots. How.r fast [in knots} is the distance between the ships changing at 4 PM? {Hote: 1 knot is a speed of 1 nautical mile per hour.) Let y 2 42:2. Find the change in 1:, y 1when I = 5 and 15.3: = {1.1 Find the differential y when if: = 5 and d3: = Ill
