Carco manufactures cars and trucks. Each car contributes $300 to profit and each truck, $400. The resources required to manufacture a car and a truck are shown in the table below. Each day, Carco can rent up to 98 Type 1 machines at a cost of $50 per machine. The company now has 73 Type 2 machines and 260 tons of steel available. Marketing considerations dictate that at least 88 cars and at least 26 trucks be produced. Vehicle Days on Type 1 Machine Days on Type 2 Machine Tons of Steel Car 0.8 0.6 2 Truck 1 0.7 3 Find the optimal solution and the sensitivity analysis using Excel. Show the steps.

Suppose A has eigenvalue \(\lambda = 3\) with corresponding eigenvector \(\vec{u} = \begin{bmatrix} -3 \\ -5 \end{bmatrix}\), and eigenvalue \(\lambda = -2\) with corresponding eigenvector \(\vec{v} = \begin{bmatrix} 3 \\ -3 \end{bmatrix}\). Find the following. \(A^{-1}\vec{u} = \begin{bmatrix} \\\\ \end{bmatrix}\) \(A^5\vec{v} = \begin{bmatrix} \\\\ \end{bmatrix}\)
Calculus Workbook 2. The displacement of a car from its starting point after \(t\) hours is given by \(d = f(t)\) miles; a graph of the function \(f\) is shown to the right.
