For this problem, the domain is the set of all solar system objects: P(r) means r is a Planet M(r) means r is a Moon O(1, y) means r orbits y Formulate the following statements using predicate logic. You may use x + y to indicate that the x and y are different. 1. All plancts orbit the sun and all moons orbit a planet. 2. Some planets have no moon. 3. Some planets have two or more moons. 4. Some objects orbit the sun that are not plancts 5. Everything that orbits the sun is a planet. (Also prove that this statement is the negation of the previous statement) 6. Pluto is a planct! 1

Rod cutting problem: A cutting factory buys long steel rods and then and cuts them into shorter rods, which it then sells. Each cut is free. The selling price is based on the length of the cut. The factory want to determine the best cuts in order to maximize its revenue. Below, the price that the factory can make for each length of rod is given. Determine the maximum revenue, rn, obtainable by cutting up the rod and selling the pieces using bottom-up dynamic-programming approach. Length, I 1 2 3 4 5 6 7 Price, pi 2 4 5 6 9 10 12 r5 = ?
