The rate at which revenue was generated (in millions of dollars per year) for a certain company for the years 2010 through 2016 can be approximated by f(t) = 340e -21t (10 sts 16), where t= 10 corresponds to the start of the year 2010. Find and interpret f(t) dt. A. The integral f(t)dt represents the total revenue from the start of 2010 to the start of 2016. Thus, the total revenue was about $ million. ( B. The integral f(t)dt represents the rate at which revenue was generated from the start of 2010 to the end of 2016. Thus, the rate was about $ million per year. DC. The integral f(t)dt represents the total revenue from the start of 2010 to the end of 2016. Thus, the total revenue was about $ million. O D. The integral | f(t)dt represents the rate at which revenue was generated from the start of 2010 to the start of 2016. Thus, the rate was about $ million per year
