Final answer:
The value of the investment after a given number of years can be found using the continuous compound interest formula: A = P * e^(rt), where A is the final value, P is the principal amount, e is the base of the natural logarithm, r is the interest rate, and t is the number of years.
Step-by-step explanation:
In this case, the value of the investment after a given number of years can be found using the continuous compound interest formula: A = P * e^(rt), where A is the final value, P is the principal amount, e is the base of the natural logarithm (approximately 2.71828), r is the interest rate, and t is the number of years.
To find the value of the investment after a given number of years, substitute the given values into the formula. In this case, the principal amount is $4000, the interest rate is 9.25% per year, and the number of years is t. So the answer is $4000e^(0.0925t).
