a) What are the annualized, continuously-compounded rates applicable for loans with maturities t₃ = 9m, respectively t₆ = 18m?

b) What is the price of a bond paying semi-annual coupon at the rate of 6.50% maturing in 21 months? Report both the clean and the dirty price. (You can assume here that each month is 30 days.)

c) What is the yield to maturity of this bond?

d) Consider the rate that can be locked in advance to borrow between dates t₂ = 6m and t₄ = 1y, i.e., the forward rate f(0, t₂, t₄). What is the value of f(0, t₂, t₄)? If t6 = 18m, what are f(0, t₂, t₆) and f(0, t₄, t₆)?
