3 Many relations in biology are expressed by power functions, known as allometric equations, of the form y=kxa, where k and a are constants. The weight of a certain snake is approximately 443x grams, where x is its length in meters. If the snake has length 0.6 meters and is growing at the rate of 0.2 meters per year, at what rate is the snake gaining weight? The rate at which the snake is gaining its weight is (Simplify your answer. Type an integer or a decimal.) grams per year.
