Oct 13, 2025 by wbrum.org 123 views

The expression $f(x) = 12(1.035)^x$ is a mathematical model that represents the monthly growth of membership in the new drama club at a school. To determine the monthly growth rate, we need to analyze the given function and extract the relevant information.

The Monthly Growth Rate

The monthly growth rate is a measure of how quickly the membership in the drama club is increasing each month. In the given function, the growth rate is represented by the base of the exponential expression, which is $1.035$ . This value indicates that the membership is increasing by a factor of $1.035$ each month.

Calculating the Monthly Growth Rate

To calculate the monthly growth rate as a percentage, we need to subtract $1$ from the base of the exponential expression and multiply the result by $100$ . This will give us the percentage increase in membership each month.

Let's perform the calculation:

$1.035 - 1 = 0.035$

$0.035 \times 100 = 3.5\%$

However, the options provided in the question are in decimal form, so we need to convert the percentage to a decimal. To do this, we divide the percentage by $100$ :

$3.5\% = 3.5 \div 100 = 0.035$

Now, we can compare this value with the options provided in the question.

Comparing the Calculated Value with the Options

The calculated value of $0.035$ represents the monthly growth rate as a decimal. To compare this value with the options, we need to convert the decimals to percentages. However, the options are in the form of $0.35\%$ and $1.035\%$ . We can see that the calculated value of $0.035$ is equivalent to $3.5\%$ , which is not among the options. However, we can see that the option $0.35\%$ is equivalent to $0.0035$ , which is not the same as our calculated value.

Conclusion

Based on the given function, the monthly growth rate is $3.5\%$ . However, this value is not among the options provided in the question. The closest option is $0.35\%$ , but this value is not equivalent to the calculated monthly growth rate.

The Correct Answer

In the previous article, we analyzed the expression $f(x) = 12(1.035)^x$ and determined that the monthly growth rate is $3.5\%$ . However, this value was not among the options provided in the question. In this article, we will provide a Q&A section to help clarify any doubts and provide additional information.

Q: What is the monthly growth rate of the drama club membership?

A: The monthly growth rate of the drama club membership is $3.5\%$ . This value represents the percentage increase in membership each month.

Q: Why is the monthly growth rate not among the options provided in the question?

A: The monthly growth rate is $3.5\%$ , which is not among the options provided in the question. The options are $0.35\%$ and $1.035\%$ , which are not equivalent to the calculated monthly growth rate.

Q: How do I calculate the monthly growth rate from the given function?

A: To calculate the monthly growth rate, you need to subtract $1$ from the base of the exponential expression and multiply the result by $100$ . This will give you the percentage increase in membership each month.

Q: What is the base of the exponential expression in the given function?

A: The base of the exponential expression in the given function is $1.035$ . This value represents the factor by which the membership is increasing each month.

Q: How do I convert the monthly growth rate from a decimal to a percentage?

A: To convert the monthly growth rate from a decimal to a percentage, you need to divide the decimal value by $100$ . For example, if the monthly growth rate is $0.035$ , you can convert it to a percentage by dividing by $100$ : $0.035 \div 100 = 3.5\%$ .

Q: What is the significance of the monthly growth rate in the context of the drama club membership?

A: The monthly growth rate is a measure of how quickly the membership in the drama club is increasing each month. This value can help the club's administrators understand the rate at which new members are joining and plan accordingly.

Q: Can I use the monthly growth rate to predict the future membership of the drama club?

A: While the monthly growth rate can provide some insight into the rate at which new members are joining, it is not a reliable method for predicting the future membership of the drama club. Many factors can influence the membership, such as changes in interest, availability of resources, and external events.
