1.Find the present value at time 0 of $15086 due at the end of4.88 years if the force of interest ?=0.023?=0.023.
2.If an investment will double in 8.15 years at a constant forceof interest ?, then
3.An investment of $1300 at t = 0 accumulates at a constantforce of interest ??= 4% for the first 4 years and at a nominalannual rate of interest of 5% compounded semiannually thereafter.Find the accumulated value of this investment at time t = 11.
4.An investment pays $1150 at time 0 and $2250 at the end of 3years. Find the accumulated value of this investment at time 8 ifthe force of interest ?t=0.02(1+t)2?t=0.02(1+t)2.
5.An investment of $1700 at t = 4 accumulates at a force ofinterest ?t=0.003+0.009t2?t=0.003+0.009t2. Find the accumulatedvalue of this investment at time t = 9.
6.How long does it take an amount to triple if the force ofinterest ?=0.062?=0.062.
