Question

1. Suppose an investment account is opened with an initial deposit of $18,500 earning 6.75% interest, compounded continuously. How much will the account be worth after 25 years? (Round your answer to two decimal places.)

2. Use the Rational Zero Theorem to find all rational zeros of the polynomial equation. (Enter your answers as a comma-separated list.)

5x³ + 19x² + 16x − 4 = 0

x = ?
