Question 3 of 10 > Find an exponential model that satisfies the given conditions. Write the amount, A, first as a function of the half-life, h, then as a function of the given unit of time, t. The initial value is 14. The half-life is 9 minutes. (Express numbers in exact form. Use symbolic notation and fractions where needed.) in terms of half-lives, A = in terms of minutes, A =
