Eigenvalues & Eigenvectorshard

A population of bacteria follows xn+1=Axn\mathbf{x}_{n+1} = A\mathbf{x}_n where A=(0.80.30.20.7)A = \begin{pmatrix} 0.8 & 0.3 \\ 0.2 & 0.7 \end{pmatrix}. The eigenvalues are λ1=1\lambda_1 = 1 and λ2=0.5\lambda_2 = 0.5. For large nn, the population distribution approaches a steady state proportional to the eigenvector of λ=1\lambda = 1. If v1=(32)\mathbf{v}_1 = \begin{pmatrix} 3 \\ 2 \end{pmatrix} is the eigenvector for λ1=1\lambda_1 = 1, what is the long-term ratio of the two species?
