Question

The quantity of an element is decaying over time such that the amount of material at

any time is given by the function S(t) = 1000(0.9)3t. Write an equivalent function
of the form S(t) = abt.

Answer 1

S(t) = 1000(0.729)^t

Explanation:

S(t) = 1000(0.9)^(3t)

S(t) = 1000((.09)^(3))^t

S(t) = 1000(0.729)^t
