Problem 1.8 You deposit $5,000 in an account earning 5% interest compounded semi-annually for 2 years and 7% interest compounded quarterly thereafter. What is the account value after 7 years? Problem 1.9 What is the equivalent effective annual (compound) interest rate in Problem 1.8? Problem 1.10 You deposit $5,000 in an account that earns 5% interest compounded annually in years 1 and 2, and thereafter a continuous rate δ(t) = 2/(t + 1) (t > 0). What is the value...

Question 13 Jason has an investment of 1,000 that accumulates at a force of interest of 8, = 0.02 +0.004. Let A be the accumulated value at time n, and B be the amount of interest earned during the sixth year. You are given that А + 10B = 1,346.13 Determine n.
At time 0, $20,000 is deposited into Fund X, which accumulates at a varying force of interest of 0.09 -0.004t. At time 0, $15,000 is deposited into Fund Y which accumulates at an annual effective discount rate of 9% for the first 5 years, and a constant force of interest for the last five years. At time t = 10, Fund X and Fund Y's accumulated values are the same. What is the constant force of interest at which Fund...

accumuldeu vdiu ul ŞSU at time t = 4. (b) For the $5000 invested in time t = 1, find the amount of interest earned during the third year of investment, i.e., between times t = 3 and t = 4. 4. It is known that a(t) if of the form at2 + bt + c. If $100 invested at time 0 accumulates to $300 at time 2 and $700 at time 4 , find the accumulated value...
1. Suppose that an investment of $3750 accumulates to $8503.08 at the end of 13 years, then the effective annual interest rate is i= 2. At an effective annual rate of interest of 5.3%, the present value of $10371.57 due in t years is $5300. Determine t= 3. a) Under simple interest rate of 6%. The effective rate of interest in the 14 th year is i14= % b) Under simple interest rate of 6%. The effective rate of interest...
5) Suppose that .02t if 0 <t< 2 St = .003t if 2 < t < 5 where t is in years. If an initial deposit of $150 when t = 0) is made (and no other deposits or withdrawals are made) then find how much is in the account at the end of the 5th year, and also find the equivalent effective annual interest rate for this 5 year period.
