Question
![**Problem Statement:**
Find the Laplace transform of the given function:
\[
f(t) =
\begin{cases}
0, & t < 7 \\
(t - 7)^4, & t \geq 7
\end{cases}
\]
**Goal:**
Calculate \(\mathcal{L}\{f(t)\} = \underline{\hspace{4cm}}\), where \(s\) is an appropriate variable.
**Instructions:**
1. Begin by identifying the function \(f(t)\) in terms of its piecewise definition.
2. For \(t < 7\), \(f(t) = 0\). For \(t \geq 7\), \(f(t) = (t-7)^4\).
3. Use the Laplace transform properties to solve for \(\mathcal{L}\{f(t)\}\).
4. Input your final expression for \(\mathcal{L}\{f(t)\}\) in the provided box.
5. Consider the variable \(s\) in the context of the Laplace transform.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd4bdfca1-c479-4089-8b74-947c8fb213c2%2F2f1a8bd4-ce6f-4f69-99ae-c403f7dff62e%2Fmatfz09_processed.jpeg&w=3840&q=75)
