Using the techniques discussed in this section, solve the following system of linear equations. Enter the solution as an ordered triple. For parametric solutions use $z = t$ as the parameter. If a solution does not exist, enter DNE for all coordinates.\\ $\begin{cases} -3x - 4y - 7z = 27\\ -y + 3z = -5\\ 4y - 6z = 8 \end{cases}$ \\ $(x, y, z) = (\qquad)$

ArrayList and linked list are non-synchronized classes. Both are constructs that hold data, but each construct does so in a different way. Discuss the main differences between an ArrayList and a linked list. What are the benefits of each data storage method? Explain using 1 example where both are used.

In the following example, a cell is surrounded by extracellular fluid that contains 95% oxygen. Inside the cell, the intracellular fluid is 7% oxygen. This means that there is more oxygen outside the cell than inside the cell. 9. Knowing that oxygen can cross the membrane by simple diffusion, if oxygen inside the cell is 7% and oxygen outside the cell is 95%, in which direction will the oxygen molecules move? the oxygen molecules will move into the cell until equilibrium is reached the oxygen molecules will move out of the cell until equilibrium is reached the oxygen molecules will not move in either directio

Problem 9. Find absolute extreme values for (1) $f(x) = x^3 - 6x^2 + 5$, $x \in [1, 5]$ (2) $g(t) = \frac{\sqrt{t}}{1 + t^2}$, $x \in [0, 2]$. Problem 10. Find the interval where f is increasing or decreasing, and find the local maximum and local minimum for $f(x) = \frac{x^2 - 24}{x - 5}$. Problem 11. Discuss the function $f(x) = \frac{x}{x^2 + 1}$ in terms of its concavity, inflection points, and local extreme values.

The Government Imposes Regulations The great industrialists' methods and their stranglehold on the nation's econ- omy worried some Americans. The railroad industry was renowned for unjust business practices, including random and unfair rates and the process of pool- ing rates and traffic. Finally, in 1887, the United States Senate created the Interstate Commerce Commission (ICC) to oversee railroad operations. This was the first federal body ever set up to monitor American business operations. The ICC could only mon- itor railroads that crossed state lines, and it could not make laws or control the railroads' transactions. Still, the ICC could require the railroads to send their records to Congress, so that Congress could initiate investigations of unfairness. Over the next several decades, the government would set up many other federal bodies to regulate American businesses. Similarly, the federal government slowly became involved in regulating trusts. In 1890, the Senate passed the Sherman Antitrust Act, which outlawed any trust that operated "in restraint of trade or commerce among the several states." For more than a decade, the provision was seldom enforced. In fact, the law was often used in the corporations' favor, as they argued that labor unions restrained trade. However, the ICC and the Sherman Antitrust Act began a trend toward federal limitations on corporations' power. Checkpoint How did the federal government regulate business?
