Task 2The cells of the battery are treated using a programmable lathe machine. The machine has 15programs that are able to control its speed. Program 1 has 11 ( N( 1) = 11) different speeds thatcan vary from 100 revolution per minute (rev/min) to 1100 (rev/min). Program 2 has 13 ( N(2) =13) speeds that can vary from 110 rev/min to 1430 rev/min ( X1(1) = 100, X2(1)=110,and so on). The number of speeds of the higher programs increases using geometric progressionand the speeds within the same program follow the same pattern of the common differenceachieved in program 1 and 2 and increase using arithmetic progression.1. Determine the general formulas of the speeds of the programs and the number ofspeeds of the programs.2. Construct a sequence using the final speed of each program.

Develop a State Table with all Inputs and Outputs for a vending machine that sales "Chip", "Water". Assuming (1) The machine only accepts Nickel, Dime, Quarter coins. (2) A bag of "Chip" is 20 cents (3) A bottle of "Water" is 45 cents (4) The machine also has a "Refund" button other than the "Chip" and "Water" buttons (5) The vending machine will automatically refund some coin once the accumulated deposit total is over 65 cents so the maximum deposit to the vending machine is 65 cents.
