Many relations in biology are expressed by power functions, known as allometric equations, of the form y equals kx Superscript a, where k and a are constants. The weight of a certain snake is approximately 439 x cubedgrams, where x is its length in meters. If the snake has length 0.5 meters and is growing at the rate of 0.3 meters per year, at what rate is the snake gaining weight?
