The height a ball bounces is less than the height of the previous bounce (friction). The heights of the bounces form a geometric sequence. Suppose a ball is dropped from one meter (1 m) and rebounds to 80% of the height of the previous bounce. What is the total distance traveled by the ball when it comes to rest?

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (-4, 0) and (6,0). the y-intercept of thefirst parabola is (0, –12). the y-intercept of the second parabola is (0-24). what is the positive difference between the avalues for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth.
