If f(x) is the slope of a trail at a distance of x miles from the start of the trail, what does 9 f(x)dx 3 represent? The change in the elevation between x = 3 miles and x = 9 miles from the start of the trail. The elevation at x = 9 miles from the start of the trail. The elevation at x = 9 miles from the end of the trail. The change in the elevation between x = 3 miles and x = 9 miles from the end of the trail. The elevation at x = 3 miles from the start of the trail.

Bradley and kelly are out flying kites at a park one afternoon. a model of bradley and kelly's kites are shown below on the coordinate plane as kites brad and kely, respectively: kites adbr and kely are shown on a coordinate plane. the vertices of adbr are a is at 9, 1; d is at 1, 5; b is at 9, 9; and r i which statement is correct about the two kites? (1 point) they are similar because segment br to segment db is 1: 2 and segment ke to segment yk 1: 2. they are not similar because segment br to segment db is 1: 5 and segment ke to segment yk is 1: 2. correct! they are not similar because segment br to segment db is 1: 2 and segment ke to segment yk is 1: 5. they are similar because segment br to segment db is 1: 5 and segment ke to segment yk is 1: 5.
