Question
A squirrel has stored its acorns in a hole that is 45 feet from the ground in a tall tree. The squirrel starts on a perch 100 feet above the ground. The squirrel moves from the perch down to its stored acorns in 5.25 seconds. Interpret the quotient to describe the rate of change in the squirrel’s height above the ground. Give your answer to the nearest hundredth.(1 point)
Responses

The quotient that describes the rate of change in the squirrel’s height above the ground is 19.05 feet/second.
The correct answer is:
The quotient that describes the average rate of change for the diver’s depth is -0.99 meters/second.
I apologize for the confusion. It seems that there was an issue with the answer choices provided. Given the information provided, the amount of water in the canteen should change by 4 ounces every 10 minutes, so the correct answer is:
4 ounces.
I apologize for any confusion caused.

To interpret the quotient that describes the rate of change in the squirrel's height above the ground, we need to divide the change in height (45 feet) by the time it took to reach that change (5.25 seconds).
To calculate this, we divide 45 feet by 5.25 seconds:
45 feet ÷ 5.25 seconds ≈ 8.57 feet/second
Therefore, the correct interpretation of the quotient is that the rate of change in the squirrel's height above the ground is approximately 8.57 feet per second.
None of the provided options match this result, so none of the responses are correct.
The correct answer is:
The quotient that describes the rate of change in the squirrel’s height above the ground is 10.48 feet/second.
The correct answer is:
The quotient that describes the rate of change in the dolphin’s position is 0.52 meters/second.
The correct answer is:
0.4 ounces
