calc applications with anti derivatives

During weeks in a certain u season, the rate at which the numbercri cases a! inuenza per 100.000 people in e muntry changed could be approximated by I'm = 3.423 e \"-105\" where I is 1e total number 0'! people per 100.0010 who have contacted inuenza and t is time measured in weeks. Esmete |(t). ie total number per 100,000 who have contacted inuenza by time t. Assume mat |(0} = 0. Itt} = Cl (Round to four decimal pieces as needed.)
