Final answer:
The equation f(t) = 24,500x(0.88)^t represents exponential decay. By substituting t = 9 into the equation, we can find f(9) = 2,156.
Step-by-step explanation:
The equation f(t) = 24,500x(0.88)^t represents exponential decay. In this equation, f(t) represents the value of a quantity at time t, x represents the initial value of the quantity, and 0.88 represents the decay factor. By substituting t = 9 into the equation, we can find f(9):
f(9) = 24,500x(0.88)^9
f(9) = 24,500x(0.0880)
f(9) = 2,156
