Use a system of inequalities to represent the situations described in Exercises 61 – 68, then solve the system using the methods developed in this section. In drawing the graph of your solution set, you may want to take into consideration that certain quantities cannot be negative and therefore you may want to restrict the solution set appropriately as we did in Example 9.
Manufacturing. Scott owns a manufacturing company that produces two models of entertainment centers. The Athens requires 4 feet of fancy molding and on average takes 4 hours to manufacture. The Barcelona needs 15 feet of molding and 3 hours to manufacture. In a given week, there are 120 hours of labor available, and the company has 360 feet of molding to use for the centers.

Prove the following. Use full sentences. Equations in the middle of sentences are fine, but do not use logical symbols. (a) (b) (n+3)2 is odd for every even integer n. It is not the case that whenever n is an integer such that 9 | n² then 9 | n.arrow_forward3. (a) (b) Prove the following logical argument using the rules of inference. Do not make use of conditional proof. Vx(J(x)O(x)) 3x(J(x) A¬S(x)) . ·.³x(O(x) ^ ¬S(x)) Rewrite the proof using full sentences, avoiding logical symbols. It does not need to mention the names of rules of inference, but a fellow CSE 16 student should be able to understand the logical reasoning.arrow_forward

The base of the cake tin has a characteristic dimension / and is illustrated in Figure 1 below, you should assume the top and bottom of the shape can be represented by semi-circles. The vertical sides of the cake tin have a height of h. As the company's resident mathematician, you need to find the values of r and h that minimise the internal surface area of the cake tin given that the volume of the tin is Vfixed- 2r Figure 1 - Plan view of the "ghost" cake tin base.
