Textbook Question
Chapter 16, Problem 30P
An aerospace company is developing a new fuel additive for commercial airliners. The additive is composed of three ingredients: X, Y, and Z. For peak performance, the total amount of additive must be at least 6mL/L of fuel. For safety reasons, the sum of the highly flammable X and Y ingredients must not exceed 2.5mL/L. In addition, the amount of the X ingredient must always be equal to or greater than the Y, and the Z must be greater than half the Y. If the cost per mL for the ingredients X, 0, and Z is 0.05, 0.025, and 0.15, respectively, determine the minimum cost mixture for each liter of fuel.

2. Consider the following argument:
(a)
Seabiscuit is a thoroughbred.
Seabiscuit is very fast.
Every very fast racehorse can win the race.
.. Therefore, some thoroughbred racehorse can win the race.
Let us define the following predicates, whose domain is racehorses:
T(x) x is a thoroughbred
F(x) x is very fast
R(x) x can win the race
:
Write the above argument in logical symbols using these predicates.
(b)
Prove the argument using the rules of inference. Do not make use of conditional
proof.
(c)
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.
