Question
![**Problem Statement:**
Solve the initial-value problem.
\[
t \frac{du}{dt} = t^2 + 3u, \quad t > 0, \quad u(4) = 48
\]
**Explanation:**
This problem is a first-order linear differential equation with an initial condition. The equation is given in terms of the derivative \(\frac{du}{dt}\) and incorporates both the variable \(t\) and the function \(u(t)\). The initial condition specifies that when \(t = 4\), the value of the function \(u(t)\) is 48. The goal is to find the function \(u(t)\) that satisfies both the differential equation and the initial condition.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8f32ed55-1a30-4945-85d1-41ddf9f2fcd9%2F7defcafd-6411-4e22-bf0b-cd09a1d627f0%2Fcju2ltr_processed.jpeg&w=3840&q=75)
