A truck with a mass of 1880 kg and moving with a speed of 12.5 m/s rear-ends a 605 kg car stopped at an intersection. The collision is approximately elastic since the car is in neutral, the brakes are off, the metal bumpers line up well and do not get damaged. Find the speed of both vehicles after the collision in meters per second.

Name and describe two Black Power organizations and their impact on American history.
a) Is there evidence that the percentage of construction workers who are illegal short-term immigrants differs in the two regions? Use \(\alpha = 0.10\). State the hypotheses for this test. H\(_0\): The distributions of worker type are the same for both regions. H\(_A\): The distributions of worker type are not the same for both regions. Identify the test statistic for the appropriate chi-square test. $\chi^2 = 9.14$ (Round to two decimal places as needed.) Identify the P-value. P-value = 0.003 (Round to three decimal places as needed.) Interpret the meaning of the results and state a conclusion. Reject H\(_0\). There is sufficient evidence to conclude that the percentage of construction workers who are illegal short-term immigrants differs in the two regions. b) Give a 90% confidence interval for the difference in proportions (Northeast minus Midwest). Assume that all necessary assumptions and conditions are satisfied. (0.0) (Round to three decimal places as needed.)
Use the matrices to show that matrix multiplication is associative.\\ $A = \begin{bmatrix} 7 & 1\\ 3 & 1 \end{bmatrix}$, $B = \begin{bmatrix} 1 & -2 & 5\\ 2 & 4 & 1 \end{bmatrix}$, and $C = \begin{bmatrix} 2\\ -1\\ 0 \end{bmatrix}$\\ Drag a matrix to each box to correctly complete the equations.\\ $(AB)C = \Box \times \begin{bmatrix} 2\\ -1\\ 0 \end{bmatrix} = \Box$\\ $A(BC) = \begin{bmatrix} 7 & 1\\ 3 & 1 \end{bmatrix} \times \Box = \Box$
A monopolistically competitive firm Multiple Choice sells products that are perfect substitutes for its competitors' products, so must compete on the basis of location. sells products that are close substitutes for its competitors' products, so will locate as far away from its competitors as possible. sometimes distinguishes its output from that of its competitors by locating in a more convenient place. will be more successful the more similar its output is to its competitors' output.
A process is modeled by a differential equation: d^2y/dt^2 + 3y(t) = 5u(t), y(0) = 0, dy/dt(0) = 0 1. Derive the transfer function model for this process. 2. For a step input change from 0 to 6.3, calculate the output response. (10)
