Shalise competed in a jigsaw puzzle competition where participants are timed on how long they take to complete puzzles of variou

s sizes.
Shalise completed a small puzzle in 75 minutes and a large jigsaw puzzle in 140 minutes. For all participants, the distribution of completion
time for the small puzzle was approximately normal with mean 60 minutes and standard deviation 15 minutes. The distribution of completion
time for the large puzzle was approximately normal with mean 180 minutes and standard deviation 40 minutes.
Approximately what percent of the participants had finishing times greater than Shalise's for each puzzle?

After being dropped from a platform, a ball bounces several times. The graph shows the height of the ball after each bounce.
Paul [167]

<u>Answer-</u>

<em>End behavior for increasing x represents that </em><em>the height of each bounce will approach 0.</em>

<u>Solution-</u>

From the graph the exponential equation is,

y=100e^{(-0.35x)}

From the properties of negative exponential function properties, as x increases, the value of y decreases.

So, in this case, as x or number of bounce increases, y or the height of bounce decreases. And eventually the value becomes zero.

Therefore, end behavior for increasing x represents that the height of each bounce will approach 0.
