Explanation Given: The given differential equation is, 3 y ″ + 2 y ′ + 8 y = t 2 + 4 t − t 2 e t sin t ... ( 1 ) Approach: The procedure of undetermined coefficients method is as follow, The standard undetermined coefficients equation is given by, a y ″ + b y ′ + c y = g ( t ) ... ( 2 ) Here, a , b , and c are real numbers and g ( t ) be a polynomial function, trigonometric function, exponential function or product of these function. Compare the given equation with standard equation. If the given equation satisfies the standard condition of the undetermined coefficient method then it can be used otherwise not. Calculation: Compare equation ( 1 ) with equation ( 2 )

A linear programming computer package is needed. Hanson Inn is a 96-room hotel located near the airport and convention center in Louisville, Kentucky. When a convention or a special event is in town, Hanson increases its normal room rates and takes reservations based on a revenue management system. A large profesional organization has scheduled its annual convention in Louisville for the first weekend in June. Hanson Inn agreed to make at least 50% of its rooms available for convention attendees at a special convention rate in order to be listed as a recommended hotel for the convention. Although the majority of attendees at the annual meeting typically request a Friday and Saturday two-night package, some attendees may select a Friday night only or a Saturday night only reservation. Customers not attending the convention may also request a Friday and Saturday two-night package, or make a Friday night only or Saturday night only reservation. Thus, six types of reservations are…
