(1) If jack was in the bedroom or Vicky was not in the bedroom, then Jack stole the neck- lace. Vicky was not in the bed room and Tom was in the bed room. If Jack is quite, then neither Vicky nor Jack stole the necklace. Therefore, If Jack is quite and Vicky is not in the bed room, then Tom stole the necklace. (a) Write the symbolic of the above argument. Let: p=jack was in the bedroom, q=Vicky was in the bedroom, r=Jack stole the neck- lace, s=Tom was in the bed room, t=Jack is quite, u=Vicky stole the neck- lace, v=Tom stole the neck- lace (1) (p v ¬q) -r (2) ¬9AS (3) t- (¬u A r) * (ta ng) - v (b) Show that the above argument is valid using Inference rules.

Solve the problem below. For your initial post in Brightspace, copy the description of your company given in the box below and then enter your solution to all three parts (parts a, b, and c) of the problem. To copy the description of your company, highlighting and using "copy" from here in Mobius and then using "paste" into Brightspace should work. However, if when you copy and paste x you get a 2 instead, then change your x2 to x^2. Hint: We covered this topic in "2-1 Reading and Participation Activities: Quadratic Equations" in Module Two. You can check your answer to part b to make sure that you are on the right track. For a certain company, the cost for producing x items is 40x +300 and the revenue for selling a items is 80r - 0.5x2. The profit that the company makes is how much it takes in (revenue) minus how much it spends (cost). In economic models, one typically assumes that a company wants to maximize its profit, or at least wants to make a profit! Part a: Set up an expression…
