A boat is being pulled into a dock by a rope attached to it and passing through a pulley on the dock, positioned 6 meters higher than the boat. If the rope is being pulled at a rate of 3 meters/second, how fast is the boat approaching the dock when it is 8 meters from the dock?

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
