A. Table 2 shows the energy savings of the dynamo system during the rst hour of operation, and the percentage by which the savings decrease each hour of continuous operation (due to increased heat losses). a. Establish a suitable geometric progression based on the values in Table 2. b. How much energy is saved during the 8th hour of operation? 0. How much energy is saved in total if the system runs for 48 hours continuously? B. Table 3 shows the energy savings over several months (the energy savings decrease with declining battery quality over time). a. Establish a suitable arithmetic progression based on the data provided in Table 3. b. How much energy is saved in the 18th month of operation? 0. How much energy is saved in total during the rst 24 months
