2 pts) Solve for $\theta$, where $\theta \in [0^\circ, 360^\circ)$ in the following equations. Round to the nearest tenth of a degree if necessary. Drawing an appropriate triangle, finding a reference angle, general solutions and applying restrictions are suggestions for full credit.\\ $\sec \theta = -\frac{2}{\sqrt{3}}$, $\theta \in$ QII.\\ b) $\tan \theta = -\frac{7}{12}$, $\theta \in$ QII.

Texts: Cybersecurity The instructor's primary introduction to cybersecurity came with what was called the "Y2K Remediation Effort," starting in 1996. In your own words, address the following two questions. You may use one or two external references; however, this is an exercise in how well you can articulate your understanding of a past situation and how it might apply in today's world of technology. (1) Describe "the problem" that stirred the technology field into action in the 1990s, caused by what people called "the Y2K bug." What do you know about the scope of this problem? (2) Is there a possibility that the type of problem you just described has had any impact on current-day cybersecurity? What do you see as potential cybersecurity threats or vulnerabilities today that might have their roots in the Y2K problem?

Solve the LP problem. If no optimal solution exists because there is no Solution Set, enter EMPTY. If no optimal solution exists because the region is unbounded, enter UNBOUNDED. Note that an unbounded region can still have an optimal solution while a bounded region is guaranteed to have optimal solutions. HINT (See Example 1.) Minimize $c = 2x - 2y$ subject to $\frac{x}{6} \ge y$ $y \ge \frac{2x}{3}$ $x + y \ge 10$ $x + 2y \le 35$ $x \ge 0, y \ge 0.$ $c = $ $(x, y) = ( 10.

4. (a) The strain hardening coefficients of copper and aluminum are 0.3 and 0.15 respectively. Discuss the differences in strain hardening behaviors of these materials based on stacking fault energies. (b) Peierls-Nabarro stress is a measure of lattice resistance to dislocation motion. Write the equation for Peierls-Nabarro stress, and explain the effect of (a) dislocation width, (b) interplanar spacing, and (c) atomic density on the magnitude Peierls-Nabarro stress. (c) Estimate the theoretical yield strength of pure iron, and compare it with experimental yield strength. Comment on the results. Cite your sources of data used.
