Question

1. in an exponential decay model, which variable typically represents time?

a. $n(t)$
b. $b$
c. $t$
d. $n_0$

Explanation:

In an exponential decay model of the form $N(t)=N_0e^{-bt}$, $t$ is the variable that typically represents time. $N(t)$ is the quantity at time $t$, $N_0$ is the initial quantity, and $b$ is the decay constant.

Answer:

C. $t$
