1. Show that if λ1 and λ2 are different eigenvalues of A and u1 and u2 are associated eigenvectors, then u1 and u2 are independent. More generally, show that if λ1, ..., λk are distinct eigenvalues of A and ui is an eigenvector associated to λi for i=1, ..., k, then u1, ..., uk are independent.

2. Show that for each eigenvalue λ, the set E(λ) = {u LaTeX: \in∈Rn: u is an eigenvector associated to λ} is a subspace of Rn.

How much is your arbitrage profit in Euros at expiration, if you know that the current exchange rate is Euro 1.2 / GBP, the 60-day forward rate is Euro 1.15 /GBP, the risk free rate in Europe is 2% and the risk free rate in the UK is 3.6%? Make your calculation so that the spot transaction is for GBP 500,000.

Answer is 23,603.66 please provide detailed solution

A person is pulling a 40 kg block of ice across an icy surface at a 25 degree angle. If the person is pulling with a force of 42 N, what is the magnitude of the acceleration of the block of ice? you may ignore drag, but not friction. Us=.1 and Uk=.03

I got this wrong on the homework and my teacher said that the normal forces does not equal mg here and that the tension is "pulling up"
