11. A group of researchers found that people prefer training films of moderate length; shorter films contain too little information, while longer films are boring. For a training film on the care of exotic birds, the reseachers determined that the ratings people gave for the film could be approximated by R(t) length of the film (in minutes). Find the film length that received the highest rating. 20t t²+100 ' where t is the
