Consider an initial investment of $100 using an accumulation function which is a second-degree polynomial. You are given that the future values of this investment at the end of six months and the first year are $120 and $150, respectively. Determine the force of interest at time t=5, a) 0.9841 b) 0.9583 c) 0.8649 d) 0.6758 e) 0.5214 Consider an initial investment of $100 using an accumulation function which is a second-degree polynomial.
