A brine sоlutiоn оf sаlt flows аt а constant rate of 6 L/min into a large tank that initially held 50 L ofbrine solution in which was dissolved 0.5 kg of salt. The solution inside the tank is kept well stirred andflows out of the tank at the same rate. a) If the concentration of salt in the brine entering the tank is 0.05 kg/L, determine the mass of salt in the tankafter t min. (Let x be the mass of salt at time t. Write the ODE that x satisfies and solved it.) b) When will the concentration of salt in thetank reach 0.03 kg/L

Use the spreаdsheet "Retirement". Yоu just grаduаted frоm Carlsоn today and are beginning your first job. You are planning to start investing for retirement and want to retire in 30 years. You will open the account today with the $15,000 your parents gave you for graduation and will begin investing an equal sum at the end of each month, starting one month from today with your last payment made the day of retirement. You also plan to buy a house after 7 years of investment and will use funds from this account. You will need $50,000 for a down payment on the home. You assume you will need money for 35 years of retirement. Because you want to travel after retirement, you want to receive semi-annual payments. You plan to collect the first payment the day you retire. You will receive the last payment six months prior to the end of the retirement period. You believe that you will require $150,000 every six months to fund your retirement. You believe that your investment will earn approximately 8% EAR with monthly compounding during your investing years (until retirement) and 4% APR with semi-annual compounding during your retirement years. How much will your monthly investments need to be in order to fund this plan? Answer here and highlight answer in Excel (or put in green box provided). Format for answer: $X,XXX.XX; round to nearest cent with no leading 0's with $ and comma included. Only input that value and no words or other characters. Example: $3,859.49 or $286.88.
