17. Money Flow The rate of a continuous flow of money starts at $5000 and decreases exponentially at 1% per year for 8 years. Find the present value and final amount at an interest rate of 8% compounded continuously. 18. Money Flow The rate of a continuous money flow starts at $1000 and increases exponentially at 5% per year for 4 years. Find the present value and accumulated amount if interest earned is 3.5% compounded continuously. 19. Present Value A money market fund has a continuous flow of money at a rate of f() = 1500 - 6012, reaching 0 in 5 years. Find the present value of this flow if interest is 5% compounded continuously. 20. Accumulated Amount of Money Flow Find the amount of a continuous money flow in 3 years if the rate is given IS by f() = 1000 - 1 and if interest is 5% compounded of continuously. at
