Answer 1

Let's go through each question one by one.

Question 1: The squirrel starts at a height of 100 feet and moves down to a height of 45 feet. The change in height is:

\[ \text{Change in height} = \text{initial height} - \text{final height} = 100 \text{ feet} - 45 \text{ feet} = 55 \text{ feet} \]

The squirrel takes 5.25 seconds to make this change. Thus, the rate of change in height is:

\[ \text{Rate of change} = \frac{\text{Change in height}}{\text{Time}} = \frac{-55 \text{ feet}}{5.25 \text{ seconds}} \approx -10.48 \text{ feet/second} \]

Answer: The quotient that describes the rate of change in the squirrel’s height above the ground is -10.48 feet/second.

---

Question 2: The dolphin jumps to an altitude of 3.5 meters above the surface and then dives 10 meters below the surface, making a total change in position of:

\[ \text{Change in position} = 3.5 \text{ m} - (-10 \text{ m}) = 3.5 + 10 = 13.5 \text{ meters} \]

The total descent takes 12.5 seconds. Thus, the average rate of change in position is:

\[ \text{Rate of change} = \frac{\text{Change in position}}{\text{Time}} = \frac{-13.5 \text{ meters}}{12.5 \text{ seconds}} \approx -1.08 \text{ meters/second} \]

Answer: The quotient that describes the rate of change in the dolphin’s position is -1.08 meters/second.

---

Question 3: If the scuba diver went down to a depth that is 10 meters lower than her starting depth, we will calculate the rate of change as follows:

\[ \text{Change in depth} = -10 \text{ meters} \]

Assuming it took 10.1 seconds:

\[ \text{Rate of change} = \frac{\text{Change in depth}}{\text{Time}} = \frac{-10 \text{ meters}}{10.1 \text{ seconds}} \approx -0.99 \text{ meters/second} \]

Answer: The quotient that describes the average rate of change for the diver’s depth is -0.99 meters/second.

---

Question 4: The car's value decreases by $4000 over the first 12 months. To find the monthly decrease:

\[ \text{Monthly decrease} = \frac{-4000}{12} \approx -333.33 \]

Answer: The amount the car's value decreases per month is -$333.33.

---

Question 5: If it is recommended to drink 24 ounces of water per hour, then in 10 minutes (which is 1/6 of an hour), the amount of water should change as follows:

\[ \text{Water change in 10 minutes} = \frac{24 \text{ ounces}}{6} = 4 \text{ ounces} \]

Answer: The amount of water in the canteen should change by 4 ounces.

---

So here are the summarized answers:

1. -10.48 feet/second
2. -1.08 meters/second
3. -0.99 meters/second
4. -$333.33
5. 4 ounces

Answer 2

ok it right but for number 5 where are you getting 6 from

Answer 3

I apologize for not explaining that clearly. The value of "6" comes from the conversion of hours to minutes.

To clarify: There are 60 minutes in an hour. If the recommendation is to drink 24 ounces of water per hour, we can break that down to a time interval of 10 minutes (which is \(\frac{10}{60}\) or \(\frac{1}{6}\) of an hour).

Here's the breakdown for clarity:

1. Water consumption per hour: 24 ounces
2. Minutes in one hour: 60 minutes
3. Water consumption per minute: \[ \text{Water per minute} = \frac{24 \text{ ounces}}{60 \text{ minutes}} = 0.4 \text{ ounces per minute} \]
4. Water consumption in 10 minutes: \[ \text{Water in 10 minutes} = 10 \text{ minutes} \times 0.4 \text{ ounces/minute} = 4 \text{ ounces} \]

So, to find the amount of water that should change in 10 minutes, we multiply the amount consumed per minute by 10 minutes.

Thus, the final answer remains that the amount in the canteen should change by 4 ounces in 10 minutes. Thank you for the question, and I hope this helps clarify my previous response!

Answer 4

are you 100% correct for ALL of them

Answer 5

Let me double-check all of the calculations and explanations for each question to ensure their accuracy.

Question 1

Situation: The squirrel moves from a height of 100 feet to 45 feet in 5.25 seconds.

1. Change in height: \[ \text{Change in height} = 100 - 45 = 55 \text{ feet} \text{ (downward)} \] This is a decrease, so we denote it as \(-55\) feet.

2. Rate of change: \[ \text{Rate of change} = \frac{-55 \text{ feet}}{5.25 \text{ seconds}} \approx -10.48 \text{ feet/second} \]

Final Answer: -10.48 feet/second is correct.

---

Question 2

Situation: The dolphin reaches 3.5 meters above the surface, then dives 10 meters below the water.

1. Change in position: \[ \text{Change in position} = 3.5 - (-10) = 3.5 + 10 = 13.5 \text{ meters} \] This results in a total change of \(-13.5\) meters when considering the highest point as a positive value and the lowest depth as negative.

2. Rate of change: \[ \text{Rate of change} = \frac{-13.5 \text{ meters}}{12.5 \text{ seconds}} \approx -1.08 \text{ meters/second} \]

Final Answer: -1.08 meters/second is correct.

---

Question 3

Situation: The diver descends 10 meters over 10.1 seconds.

1. Change in depth: \[ \text{Change in depth} = -10 \text{ meters} \]

2. Rate of change: \[ \text{Rate of change} = \frac{-10 \text{ meters}}{10.1 \text{ seconds}} \approx -0.99 \text{ meters/second} \]

Final Answer: -0.99 meters/second is correct.

---

Question 4

Situation: A car's value decreases by $4000 in 12 months.

1. Monthly decrease: \[ \text{Monthly decrease} = \frac{-4000}{12} \approx -333.33 \]

Final Answer: -$333.33 is correct.

---

Question 5

Situation: 24 ounces of water per hour means in 10 minutes:

1. Water consumed per minute: \[ \text{Water per minute} = \frac{24 \text{ ounces}}{60 \text{ minutes}} = 0.4 \text{ ounces per minute} \]

2. Water consumed in 10 minutes: \[ \text{Water in 10 minutes} = 10 \text{ minutes} \times 0.4 \text{ ounces/minute} = 4 \text{ ounces} \]

Final Answer: 4 ounces is correct.

Answer 8

hi so number one why do you use the 45

Answer 9

Let's clarify Question 1 step by step to make sure everything is clear, especially regarding why we are using the height of 45 feet.

Question 1 Breakdown:

Problem Statement:

• The squirrel has stored its acorns in a hole 45 feet from the ground.
• 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.

Understanding the Movement:

1. Starting Height: The squirrel starts at 100 feet above the ground.
2. Final Height: The squirrel ends at the location where the acorns are stored, which is 45 feet above the ground.

Calculating Change in Height:

• Change in Height: This is calculated as the difference between the initial height and the final height.

\[ \text{Change in Height} = \text{Initial Height} - \text{Final Height} \]

Substituting the values:

\[ \text{Change in Height} = 100 \text{ feet} - 45 \text{ feet} = 55 \text{ feet} \]

Sign Convention:

• Since the squirrel is moving downward to reach its acorns, we represent this change as negative:

\[ \text{Change in Height (downward)} = -55 \text{ feet} \]

Rate of Change Calculation:

• We find the rate of change by dividing the change in height by the time taken:

\[ \text{Rate of Change} = \frac{\text{Change in Height}}{\text{Time}} = \frac{-55 \text{ feet}}{5.25 \text{ seconds}} \]

Calculating the above gives:

\[ \text{Rate of Change} \approx -10.48 \text{ feet/second} \]

Summary:

• We use the height of 45 feet because that is the squirrel's final height after it descends from 100 feet. The change of height reflects the movement down to where the acorns are stored.

There is no mistake in using the height of 45 feet; it represents the final position of the squirrel. I hope this clarifies why the height of 45 feet is important in the calculations! If you have any further questions or points of confusion, feel free to ask.

Answer 10

you sure number 4 right

Answer 11

Let’s take another look at Question 4 to ensure the calculations and conclusions are correct.

Question 4 Breakdown:

Problem Statement:

• A car’s value decreases by $4000 in the first 12 months.
• We want to know how much the value decreases per month.

Calculation:

To find the monthly decrease, we can divide the total decrease in value by the number of months:

\[ \text{Monthly Decrease} = \frac{\text{Total Decrease}}{\text{Number of Months}} = \frac{-4000}{12} \]

Performing the Calculation:

\[ \text{Monthly Decrease} = \frac{-4000}{12} \approx -333.33 \]

Interpretation:

• The negative sign indicates a decrease in value.
• Therefore, the value of the car decreases by approximately $333.33 per month.

Conclusion:

The answer of -$333.33 is indeed correct for Question 4.
