(3 pt) In an industrial setting, a piece of equipment requires lubrication over time to prevent friction and wear. The rate at which lubricant is applied over time is modeled by the function 𝐿(𝑡)=𝑡⋅𝑒−2𝑡, where L(t) is the rate of lubrication in liters per hour and t is the time in hours. Determine the total amount of lubricant applied to the machine over the first 3 hours of operation. Solution To find the total amount of lubricant applied over the first 3 hours, we need to integrate the lubrication rate function over the interval from 0 to 3 hours. 1. Set up the integral: The total amount of lubricant 𝐴 is given by: 𝐴=∫ L(𝑡) 3 0  𝑑𝑡 Substitute the given lubrication rate function: � �=∫t⋅𝑒−2𝑡 3 0  𝑑𝑡 2. Apply integration by parts: For integration by parts, we identify parts of the integrand: � �=𝑡 and 𝑑𝑣=𝑒(−2𝑡 )𝑑𝑡 (…) Complete the calculations 7. Final Answer: The total amount of lubricant applied to the machine over the first 3 hours is 1 4 −5⋅𝑒−6 4 liters.
