When data consist of percentages, ratios, growth rates, or other rates of change, the geometric mean is a useful measure of central tendency. For n data values the geometric mean, assuming all data values are positive, is as follows. To find the average growth factor over 5 years of an investment in a mutual fund with growth rates of 8.9% the first year, 12.4% the second year, 14.2% the third year, 4.4% the fourth year, and 6.7% the fifth year, take the geometric mean of 1.089, 1.124, 1.142, 1.044, and 1.067. Find the average growth factor of this investment. (Round your answer to four decimal places.)

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?
