Fund A accumulates at a force of interest 0.05/1 + 0.05t at times t (t greaterthanequalto 0). Fund B accumulates at a force of interest 0.05. You are given: The amount in Fund A at time zero is 1,000. The amount in Fund B at time zero is 500. The amount in Fund C at any time t (t greaterthanorequalto 0) is equal to the sum of the amount in Fund A and the amount in Fund B. Fund C accumulates at a force of interest delta_t (t greaterthanorequalto 0). Calculate delta_2
