Use Table 1 to evaluate all integrals involved in any solutions of Problems 71 – 94. 92. Politics. The number of voters (in thousands) in a metropoli- tan area is given approximately by f ( t ) = 500 2 + 3 e − t t ≥ 0 where t is time in years. Find the average number of voters during the period from t = 0 to t = 10.
