II-19 PRACTICE MULTIPLE CHOICE TEST 5 1. You are given 8t = t ~ 1 for 2:::; t ~ 10. For anyone year interval between nand n + 1, with 2 :::; n :::; 9, calculate the equivalent d(2). The accumulated value of 1 at time t, for 0:::; t :::; 1, is given by a second degree polynomial in t. You are given (i) the nominal rate of interest convertible semiannually for the first half of the year is 5% per year, and (ii) the effective rate of interest for the year is 4% per year. Find the value of 8.75, Two funds, A and B, start with the same amount. Fund A grows at an annual interest rate of i > 0 for n years, and at an annual interest rate of j > 0 for the next n years. Fund B grows at an annual interest rate of k > 0 for 2n years. Fund A equals 1.5 times Fund B after n years. The amounts in the two funds are equal after~71:years.

What is the amount of principal included in the eighth payment? 10. An annuity provides for 30 annual payments. The first payment of 100 is made immediately and the remaining payments increase by 8% per year. Interest is calculated at 13.4% per year. Calculate the present value of the annuity. 11. John took out a 2,000,000 construction loan, disbursed to him in three installments. The first installment of 1,000,000 is disbursed immediately, and this is followed by two 500,000 installments at six month intervals. The interest on the loan is calculated at a rate of 15% convertible semiannually and accumulated to the end of the second year. At that time the loan and accumulated interest will be replaced

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
