If the sales of a business are growing oontinuousljgrr according to the function 31:] =1Els\" where 31:} is the sales in dollars on the rm then the total of all sales between the 11'\" and the lib day is given by the FETIH- Find the total of all sales between 1:11) and r=2IJ. It can be shown that if v(r) is the velocity of a car in km/h at time , then the distance the car has traveled from time r =a hours to time / =b hours is given by the definite integral [v(r)di . Find the distance traveled by a car from time /=0 hours to time =4 hours for the following velocity functions. a. v(t) =100+1 b. v(t) =100+10cos 4
