Concept explainers
Body mass index The body mass index (BMI) for an adult human is given by the function B = w/h2, where w is the weight measured in kilograms and h is the height measured in meters. (The BMI for units of pounds and inches is B = 703 w/h2.)
a. Find the rate of change of the BMI with respect to weight at a constant height.
b. For fixed h, is the BMI an increasing or decreasing function of w? Explain.
c. Find the rate of change of the BMI with respect to height at a constant weight.
d. For fixed w, is the BMI an increasing or decreasing function of h? Explain.

- The resistance of a copper wire carrying an electrical current is directly proportional to its length and inversely proportional to its cross-sectional area. A copper wire with a diameter of 0.0126inch has a resistance of 64.9ohms per thousand feet. What length of 0.0201-inch-diameter copper wire will produce a resistance of 33.5ohms?arrow_forwardEstimate the age of a newly discovered fossil for which the ratio of carbon-14 to carbon-12 is R=1/1014.arrow_forwardFrictional 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.
