Metabolic Rate The basal metabolic rate (in kcal/day) for large anteaters is given by
where x is the anteater’s weight in kilograms. * Source: Wildlife Feeding and Nutrition.
(a) Find the basal metabolic rate for anteaters with the following weights.
- (i) 5 kg
- (ii) 25 kg
Technically, kilograms are a measure of mass, not weight. weight is a measure of the force of gravity. which varies with the distance from the center of Earth. For objects on the surface of Earth, weight and mass are often used interchangeably, and we will do so in this text.
(b) Suppose the anteater’s weight is given in pounds rather than kilograms. Given that I lb = 0.454 kg, find a function x = g(z) giving the anteater’s weight in kilograms if z is the animal’s weight in pounds.
(c) Write the basal metabolic rate as a function of the weight in pounds in the form y = azb by calculating f(g(z)).
