Understanding Exponential Functions

Exponential functions are a fundamental concept in mathematics, and they play a crucial role in modeling real-world phenomena such as population growth, chemical reactions, and financial calculations. The general form of an exponential function is $f(x) = ab^x$, where $a$ is the initial value, $b$ is the base, and $x$ is the exponent.

In the given expression, the exponential function is $e^{0.046 \times 12}$. Here, the base is the mathematical constant $e$, which is approximately equal to 2.71828. The exponent is $0.046 \times 12$, which represents the rate of growth.

Evaluating the Exponent

To evaluate the exponent, we need to multiply 0.046 by 12.

$$0.046 \times 12 = 0.552$$

Understanding the Expression

Now that we have evaluated the exponent, we can rewrite the expression as:

$$A = 77,000 \cdot e^{0.552}$$

Evaluating the Exponential Function

To evaluate the exponential function, we need to calculate $e^{0.552}$. This can be done using a calculator or a computer program.

$$e^{0.552} \approx 1.732$$

Evaluating the Expression

Now that we have evaluated the exponential function, we can substitute the value back into the expression.

$$A = 77,000 \cdot 1.732$$

Calculating the Final Value

To calculate the final value, we need to multiply 77,000 by 1.732.

$$A \approx 134,044$$

Conclusion

In this article, we evaluated the expression $A = 77,000 \cdot e^{0.046 \times 12}$ using the principles of exponential functions and mathematical operations. We broke down the expression, understood its components, and ultimately arrived at a numerical solution. The final value of the expression is approximately 134,044.
