Design an elevator control system for an 8 floors building, draw
the logic diagram, and illustrate the system with the following
situations:
1. The car is on the ground floor, John Doe wants to go from
ground floor to 7th floor;
2. The car is on 8th floor, John Doe wants to go from 6th floor
to the ground floor;
3. The car is moving up from 4th floor to 7th floor, John Doe
wants to go from 6th floor...
Prove the following equivalences without using truth tables, and
specify at each step of your proof the equivalence law you are
using.
(a) ¬ (p ∨ (¬ p ∧ q)) ≡ ¬ p ∧ ¬ q
(b) ( x → y) ∧ ( x → z) ≡ x → ( y ∧ z)
(c) (q → (p → r)) ≡ (p → (q → r))
(d) ( Q → P) ∧ ( ¬Q → P) ≡ P
(Explain each step in depth and show your logic. Show formulas
and the reasons for doing what your doing)
You are an analyst evaluating Up-and-Coming Airlines Inc., a
very hot potential acquisition candidate your company is
considering. Up-and-Coming currently has no debt and you estimate
that it should be able to generate $1 million a year from its
existing assets (after tax cash flow). Furthermore, it has the
opportunity to invest one-half of its earnings indefinitely. You
estimate that because...
Give an example of each of the following, give structure and
name: an organic halide, an alcohol, an ether, an aldehyde, a
ketone, a carboxylic acid, an ester, an amine, and an amide.
(Explain each step in detail. show your logic, Do not just
provide answer and formulas.)
Will-O-Wind Airlines always invests (in non-depreciating
assets) 20% of its earnings, which will be next period (Period 1)
$3 per share. The rest it pays out as dividends. Its investment
opportunities currently earn (and are expected to earn in the
indefinite future) 18%. There are no taxes. The risk adjusted
required rate of return on this stock is 10%. What is its
price?
