Illustration 26. A firm reported that its net worth in the year 2012-13 to 2016-17 was as follows: Year 2012-13 2013-14 2014-15 2015-16 2016-17 Net worth 100 112 120 133 147 Plot the above data in the form of a semi-logarithmic graph.

The geometric mean is often used in business and economics for finding average rates of change, average rates of growth, or average ratios. Given n values (all of which are positive), the geometric mean is the nth root of their product. The average growth factor for money compounded at annual interest rates of 8.6%, 4.6%, and 1.2% can be found by computing the geometric mean of 1.086, 1.046, and 1.012. Find that average growth factor, or geometric mean. What single percentage growth rate would be the same as having three successive growth rates of 8.6%, 4.6%, and 1.2%? Is that result the same as the mean of 8.6%, 4.6%, and 1.2 %? The average growth factor, or geometric mean, is (Round to four decimal places as needed.) C

To compute a student's Grade Point Average (GPA) for a term, the student's grades for each course are weighted by the number of credits for the course. Suppose a student had these grades: 4.0 in a 5 credit Math course 2.5 in a 3 credit Music course 2.7 in a 5 credit Chemistry course 3.3 in a 6 credit Journalism course What is the student's GPA for that term? Round to two decimal places Student's GPA =
1. Chemical Acidity In chemistry, the acidity of a water-based solution is measured by the concentration of hydrogen ions in the solution (in moles per liter). The hydrogen-ion concentration is written [H*]. Because such concentrations usually involve negative powers of ten, negative orders of magnitude are used to compare acidity levels. The measure of acidity used is pH, the opposite of the common log of the hydrogen-ion concentration: pH = -log[H] More acidic solutions have higher hydrogen-ion concentrations. A certain brand of lemon juice has a pH of 2.1, and a certain brand of cleaning ammonia has a pH of 11.6. a) Find the hydrogen-ion concentrations for the lemon juice and the ammonia. b) How many times greater Is the hydrogen-ion concentration of the lemon juice than the ammonia?
