When the boat moves on the surface of the water the resistance force of the environment F is directl...: ответ на тест 860720 - Математика

When the boat moves on the surface of the water the resistance force of the environment F is directly proportional to the speed v (, where  - coefficient of proportionality). At the moment of the engine shutdown the outboard motorboat is moving at a speed of 224 m/min., and 3 min. later it’s speed is equal to 112 m/min. 9 min. after the engine shutdown the outboard motorboat will be moving at a speed of ______ m/min.

When the boat moves on the surface of the water the resistance force of the environment F is directly proportional to the speed v (, where  - coefficient of proportionality). At the moment of the engine shutdown the outboard motorboat is moving at a speed of 240 m/min., and 2 min. later it’s speed is equal to 120 m/min. 6 min. after the engine shutdown the outboard motorboat will be moving at a speed of ______ m/min.

At the moment of the engine shutdown the outboard motorboat is moving at a speed of 224 m/min., and 1 min. later it’s speed is equal to 112 m/min. 4 min. after the engine shutdown the outboard motorboat will be moving at a speed of ______ m/min..

When the boat moves on the surface of the water the resistance force of the environment F is directly proportional to the speed v (, where  - coefficient of proportionality). At the moment of the engine shutdown the outboard motorboat is moving at a speed of 192 m/min., and 1 min. later it’s speed is equal to 96 m/min. 8 min. after the engine shutdown the outboard motorboat will be moving at a speed of ______ m/min.

Captain Silver buried treasure on a desert island. There are only two palms on this island: a small one and a big one. They are situated at a distance of 400 m from each other. Silver told the rest of the pirates that the treasure is located at a three times greater distance from the small palm than from the big one. If L is the largest possible length of the ditch the pirates have to dig to find the treasure, then the value of the expression  is equal to…
