Compute the price of a zero-coupon bond (ZCB) that matures at time t=10 and that has face value 100

Compute the price of a forward contract on the same ZCB of the previous question where the forward contract matures at time t=4.

Compute the initial price of a futures contract on the same ZCB of the previous two questions. The futures contract has an expiration of t=4.

Compute the price of an American call option on the same ZCB of the previous three questions. The option has expiration t=6 and strike =80.

Compute the initial value of a forward-starting swap that begins at t=1, with maturity t=10 and a fixed rate of 4.5%. (The first payment then takes place at t=2 and the final payment takes place at t=11 as we are assuming, as usual, that payments take place in arrears.) You should assume a swap notional of 1 million and assume that you receive floating and pay fixed.)
