2.) The measure of the electrical resistance of a wire is proportional to the measure of its length and inversely proportional to the square of the measure of its diameter. Suppose that the resistance of a wire of given length is computed from a measurement of the diameter with a possible 2 percent error. Find the possible percent error in the computed value of the resistance.

Assume that an r of .80 describes the relationship between daily food intake, mea-sured in ounces, and body weight, measured in pounds, for a group of adults. Would a shift in the units of measurement from ounces to grams and from pounds to kilograms change the value of r ? Justify your answer

1. Length C in cm is proportional to length I in inches. Find the equation of variation if I = 5.34 inches when C = 13.5636 cm. (All measurements are exact.)

The loudness, L, of a sound (measured in decibels, dB) is inversely proportional to the square of the distance, d, from the source of the sound. For a person 7 feet from a sound source, suppose the loudness is 85 decibels. How loud is the sound source when the person is 46 feet away? (Round your answer to two decimal places if necessary). dB Question Help: D Post to forum Submit Question esc 仑 G Search or type URL @ $ % 1 2 3 4 5 6 Q W E R A S D F G ock
