Select the correct answer. An experiment observing the growth of two germ strand populations finds these patterns.
• The population of the first germ is represented by the function A(z) = (1.3)5+9.
• The population of the second germ is represented by the function B(x) =
(1.3)45+1
Which function best represents function R, the ratio of the population of the second germ to the population

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?
