In the year 2000, you invested money in a money market account. The value of your investment t years after 2000 is given by the exponential growth model A = 1900e^(0.058t). By what percentage is the account increasing each year?

Your growth factor will be $g = {e}^{0.058} = 1.0597 \ldots$
And you can rewrite as $A = 1900 {\left({e}^{0.058}\right)}^{t} = A \cdot {1.0597}^{t}$
A growth factor can be converted to a percentege growth by realizing that $0.0597$ gain is equivalent to 0.0597xx100%=5.97%
