Write an
exponential function in the form y=ab^x that goes through points (0,18) and (9,9216).

Given the following similar triangles what is the area of triangle b ? a) 1 b)1.8 c)3.2 d)5

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?

Icould really use some with this question.
