If a function f represents a system that varies in time, the existence of lim t→∞limf(t) means that the system reaches a steady state (or equilibrium). For the following systems, determine whether a steady state exists and give the steady-state value.

Identify the function that describes the system: p(t) = \frac{1500}{3 + 2e^{-0.1t}}.
To determine if a steady state exists, evaluate the limit of p(t) as t approaches infinity: \lim_{t \to \infty} p(t).
Observe that as t approaches infinity, the term e^{-0.1t} approaches zero because the exponential function decays to zero.
Substitute e^{-0.1t} with 0 in the expression for p(t) to simplify the limit: \lim_{t \to \infty} \frac{1500}{3 + 2 \cdot 0}.
Calculate the simplified expression to find the steady-state value: \frac{1500}{3}.
