Let \(\mathcal{B}=\left\{\begin{bmatrix}2\\-3\end{bmatrix},\begin{bmatrix}3\\-5\end{bmatrix}\right\}\) and \(\mathcal{B}^{\prime}=\left\{\begin{bmatrix}5\\4\end{bmatrix},\begin{bmatrix}1\\1\end{bmatrix}\right\}\). Find the transition matrix \(P_{\mathcal{B}\to\mathcal{B}^{\prime}}\).

  Exam 2 Definitions 1.) [5 points each] Complete both of the following definitions. You ONLY have to write out what correctly finishes the definition, not the part that is given. a.) If \(S=\left\{v_{1},\ldots ,v_{k}\right\}\) is a set of vectors in a vector space \(V\), then \(S\) is linearly independent if: b.) If \(S=\left\{v_{1},\ldots ,v_{k}\right\}\) is a set of vectors in a vector space \(V\), then \(S\) is a basis for \(V\) if: The use of math tags around this note triggers MathJax to display the LaTex written on this page as MathML objects.

Which constitutional amendment allows citizens to feel safe from illegal searches and seizures?

How has the relationship between mass media and government changed in the past few decades?  Explain whether changes in technology have given the media more or less power to influence public policy and cite specific examples. (2 points)

Let \(V=\mathbb{R}^{2}\) with the following operations \[\begin{align} \left(x_{1},y_{1}\right)\oplus\left(x_{2},y_{2}\right)&=\left(x_{1}+x_{2}+1,y_{1}+y_{2}-1\right)\\k\otimes\left(x,y\right)&=\left(kx,ky\right) \end{align}\] Show that \(V\) is not a vector space by showing that it does not satisfy \[ k\otimes\left(\overrightarrow{a}\oplus\overrightarrow{b}\right) =\left(k\otimes\overrightarrow{a}\right)\oplus\left(k\otimes\overrightarrow{b}\right)\]
