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)).

- Frictional Force The frictional force F between the tires and the road required to keep a car on a curved section of a highway is directly proportional to the square of the speed s of the car. If the speed of the car is doubled, the force will change by what factor?arrow_forwardA driver of a car stopped at a gas station to fill up his gas tank. He looked at his watch, and the time read exactly 3:40 p.m. At this time, he started pumping gas into the tank. At exactly 3:44, the tank was full and he noticed that he had pumped 10.7 gallons. What is the average rate of flow of the gasoline into the gas tank?arrow_forwardpH The hydrogen ion concentration of fresh egg whites was measured as [H+]=1.3x108M Find the pH, and classify the substance as acidic or basic.arrow_forward

The BMI measures the ratio of weight to height. The formula for calculating BMI is:Where w = weight in pounds and h = height in inches. An adult whose BMI is: less than 18.5 is considered underweight, between 18.5 and 25 is considered normal weight, between 25 and 30 is overweight, and over 30 is considered obese.Determine which category an adult female who weighs 124 pounds and is 5 feet tall (60 inches) would be considered.
