Where k is a positive constant and g is the acceleration due to gravity, is a model for the velocity v of a body of mass m that is falling under the influence of gravity. Because the term −kv represents air resistance, the velocity of a body falling from a great height does not increase without bound as time t increases. Use a phase portrait of the differential equation to find the limiting, or terminal, velocity of the body.

Analyze the analogy and read the information below it. fish : fin : : bird : wing if you were reading this aloud, you would say, "fish is to fin as bird is to wing." this analogy uses parts of an animal to relate to the whole animal. much like how a fin a fish move, so does a wing a bird move. which analogy also uses parts to relate to the whole? sky : blue : : dirt : brown flower : petal : : tree : leaf car : road : : boat : water food : sandwich : : sport : softball
