Which of the following are important limitations of K-means Clustering? The user has to specify K (the number of clusters) to the algorithm K-means Clustering is only good at detecting roughly spherical-shaped clusters and cannot detect other patterns like elongated clusters K-means Clustering is quite sensitive to any outliers present in the data All of the above

Suppose two countries produce clothing and food. Country A has five units of labor. It can produce 40 units if cloth with one unit of labor. Country A can produce 2 ton of food with one unit of labor. Country B also has five units of labor. It can produce 36 cloth with one unit of labor and 1 ton of food with one unit of labor. Question 1. Show all your work. A. Which country has an absolute advantage in the production of cloth? B. Which country has an absolute advantage in the production of food? C. Which country has a comparative advantage in the production of cloth? D. Which country has a comparative advantage in the production of food? E. Plot the production Possibilities curve for country A. F. Plot the production Possibilities curve for country B. Question 2. Suppose the international price for these two goods (the Terms of Trade) is 30. This means that 30 units of cloth trade for 1 ton of food. A. Plot the consumption possibilities curve for country A (use the original graph in question 1E. B. Would this country be better off or worse off? Explain.

Given two binary trees. We need to merge them into a new binary tree. The merge rule is that if two nodes overlap, then sum node values up as the new value of the merged node. Otherwise, the non-null node will be used as the node of new tree. Apply both recursive and Iterative Solutions. (2 points).

A message signal $m(t)$ is defined as, $\begin{cases} 1, & -2 \le t < -1, \\ -t, & -1 \le t < 0 \\ t, & 0 \le t < 1, \\ 1, & 1 \le t < 2 \\ 0 & others \end{cases}$ The unit for the time in above equation is second. The carrier is given as $c(t) = A_ccos(2\pi f_ct)$ where $A_c = 1$ and $f_c = 10Hz$. 1. Sketch the waveform of the FM and PM modulations. 2. Identify the amplitude for the most significant seven frequency components for FM modulation signal where $m(t) = A_mcos(2\pi f_mt)$ and $A_m = 1.5v, f_m = 1.5Hz$ and $k_f = 2.5Hz/v$. Use the function of stem to plot the spectrum.

Text: Write a function named ballistics() making use of derivative. The function will receive three arguments: a polynomial s which represents the trajectory, a number t to be evaluated whereby the function will determine either the position, velocity, or acceleration at time t based on a string flag ['s'|'v'|'a'] for the return of position, velocity, or acceleration. The position of an object at any time t is given by s = 75t - 20t² + t³. Use your function to generate an equation that provides the position of the object at any time t and evaluate the distance at t = 2s. Use your function to generate an equation that provides the velocity of the object at any time t and evaluate the velocity at t = 2s. Use your function to generate an equation that provides the acceleration of the object at any time t and evaluate the acceleration at t = 2s. Develop another function or modify your function so that it draws a plot similar to that shown below in the sample output (note the range shown below is t = 0 to t = 4), this function will use plot to plot the velocity between t = 0 and t = 6.5, with a step size of 0.1. Modify your function so that your function states the range between t = 0 and t = 6.5 where your velocity is positive.
