Given two sets S and T, the direct product of S and T is the set of ordered pairs S × T = {(s, t)|s ∈ S, t ∈ T}.Let V, W be two vector spaces over F. (a) Prove that V × W is a vector space over F under componentwise addition and scalar multiplication (i.e. if (v1, w1),(v2, w2) ∈ V × W, then (v1, w1) + (v2, w2) = (v1+w1, v2+w2) and a(v, w) = (av, aw)...

The amount of carbon-14 present in a tree is given by the formula C(t)=C0e−.00012t, where C0 is the amount of carbon-14 present in it at the time of its death and t is the number of years that have elapsed since it died. If the plant has 15% of its original carbon-14, how old is it?

9. Given: C = $5.25, P = $2.75, S = $48, K = $39, T = 6 months, r = 3.25% p.a. a. What would you do to exploit these quotes? (List the transactions.) What would be your riskless arbitrage profit? b. How could you synthetically short-sell an asset using only options and borrowing or lending at the risk-free rate? Would you be better off short-selling the stock, or synthetically short-selling it using options?

Given: C = $4.00, P = $6.00, S = $42, K = $45, T = 3 months, r = 8%. The option contracts are written on 100 units of the underlying asset. (Show work.) What would you do to exploit these quotes? (List all transactions you would make.) What would be your riskless profit? How could you synthetically sell a call option? What would be the cash flow from doing this? (i.e., What is the synthetic call premium?)
