I just need the cash flow diagram that's all thank you and God bless:)

1. The salary of Mr. Cruz is increased by 30% every 2 years beginning January 1, 1982. Counting from that date, at what year will his salary just exceed twice his original salary? 2. How long will it take for an investment to double its amount if invested at an interest rate of 6% compounded bi-monthly? 3. A sum of P 1,000 is invested now and left for eight years, at which time the principal is withdrawn. The interest that has accrued is left for another eight years. If the effective annual interest rate is 5%, what will be the withdrawal amount at the end of the 16th year
