two LORAN stations are positioned 232 miles apart along a straight shore. the stations trasnmit synchronized pulses which travel at the speed of light (186,000 miles per second) in order to find the coordinates of ships in the area. the station closest to a ship being tracked by the LORAN stations is called the master station.
A: a ship records a time difference of 0.000860 second between the LORAN signals. determine where the ship would reach shore if it were to follow the indicted byperbolic path.
B: if the ship were to enter a habor located between the two stations 32 miles from the master station, which time difference should it be looking for?
C: if the ship is 80 miles offshore when the desired time difference is obtained, what is the exact location of the ship?
You are beginning a small business, Barely Bears, that will manufacture plush toy bears. The cost of buying the intial sewing equipment is $425. additionally the material for each plush bear cost $1.75. the average cost per bear is C=1.75x+425/x where x represents the number of bears the business has produced. use a graphing utility to sketch a graph of the average cost equation and then find the the cost to manufacture 30 toy bears. What happens to the average cost if you produce 300 toy bears? what does the limiting cost per bear appear to be?
