Asked by the awner man
As part of a science experiment, Natasha drops a bouncy ball from various heights, h, and observes the height to which the ball rebounds, r. The table shows the results of Natasha's experiment.
Initial height, h (in meters) Rebound height, r (in meters)
0.30 0.27
0.50 0.45
0.80 0.72
1.00 0.9
1.20 1.08
Which equation represents the proportional relationship between the initial height and the rebound height of the bouncy ball?
A. r=0.9h+0.1
B. r=0.9h
C. r=0.1h
D. r=0.9h-0.1
