You are skiing down a mountain with a vertical height of 1100 feet. The distance from the top of the mountain to the base is 2200 feet. What is the angle of elevation from the base to the top of the mountain?

This graph shows which inequality? a ≤ –3 a > –3 a ≥ –3 a < –3

Which statement explains how you could use coordinate geometry to prove the opposite sides of a quadrilateral are congruent? a. use the slope formula to prove the slopes of the opposite sides are the same. b. use the slope formula to prove the slopes of the opposite sides are opposite reciprocals. c. use the distance formula to prove the lengths of the opposite sides are the same. d. use the distance formula to prove the midpoints of the opposite sides are the same.

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.
