Ship A is traveling west toward a light house at 15 km/hr. Ship B is traveling north away from lighthouse at 10km/hr. x is distnace between ship A and lighthouse at time t, and y is distance between ship B and lighthouse at time t.
a. find the distance in km, between ship A and Ship B if x=4 and y=3. ((do i use pythagorean thm?)
b. Find rate of change in km/hr of the distance between the two ships if x = 4km and y=3 km. (Does the distance between the two ships get smaller??)
c. let theta be the angle wit h a vertex of the angle formed between light house and ship B (ship A as vertex). find the rate of change in theta, in radians per hour when x = 4 km and y = 3km.
THANKS so much for any help at all, you dnt nee to do them all to help, just any help is GREATLY appreciated! :)
