Question 1 When simplifying $2[8-7[25-(2+3)^2]]$, we should be simplifying the inner-most parentheses first: $(2+3)=5$ A True B False. You need to simplify exponents first: $3^2=9$ C False. We should be subtracting in the brackets first: $8-7=1$. D False. We need to square both numbers inside the parentheses first: $2^2+3^2=4+9$.

This is the first part of a four-part problem. Let P = \begin{bmatrix} 9 & -4 \\ 15 & -7 \end{bmatrix} \vec{x}_1(t) = \begin{bmatrix} 2e^{2t} - 4e^{-t} \\ 3e^{2t} - 10e^{-t} \end{bmatrix}, \vec{x}_2(t) = \begin{bmatrix} 4e^{2t} + 2e^{-t} \\ 6e^{2t} + 5e^{-t} \end{bmatrix} a. Show that $\vec{x}_1(t)$ is a solution to the system $\vec{x}' = P\vec{x}$ by evaluating derivatives and the matrix product Enter your answers in terms of the variable $t$. $\vec{x}_1'(t) = \begin{bmatrix} 9 & -4 \\ 15 & -7 \end{bmatrix} \vec{x}_1(t)$ $\begin{bmatrix} \\ \\ \end{bmatrix} = \begin{bmatrix} \\ \\ \end{bmatrix}$ b. Show that $\vec{x}_2(t)$ is a solution to the system $\vec{x}' = P\vec{x}$ by evaluating derivatives and the matrix product Enter your answers in terms of the variable $t$. $\vec{x}_2'(t) = \begin{bmatrix} 9 & -4 \\ 15 & -7 \end{bmatrix} \vec{x}_2(t)$ $\begin{bmatrix} \\ \\ \end{bmatrix} = \begin{bmatrix} \\ \\ \end{bmatrix}$
