Compound helicopter...?Compound Helicopters 0 Introduction Among Leonardo da Vinci’s works in the 15th century can be found a sketch of a machine that, with its screw-type propeller, seemed meant to achieve vertical flight. It was Gustave de Ponton d’Amecourt of France, however, that coined the word ‘helicopter’ in 1861.1 At about the same time, Mortimer Nelson of the United States was granted patent by the US Patent Office for his design of a flying machine, which he called Aerial Car. The flying machine had a length of 33 feet and weighed half a ton and was meant to be used with a hot air balloon. It had a tapered body, a pear-shaped rudder at the stern, and two standing poles attached at the top of the fuselage with two sets of rotors meant to spin... in...

Mixture and compound...? Compounds and Mixtures, Ionic and Covalent Bonds College: Compounds and Mixtures, Ionic and Covalent Bonds A mixture is a substance that is composed of two or more elements mixed physically but not chemically bonded (Patten, 1995). Simple physical means such as filtering, use of a magnet or picking if the elements have big grains can separate mixtures (Phillips, 1998). A compound on the other hand, is a pure substance made of two or more chemically combined elements. Compounds are separable by chemical means such as electrolysis, oxidation and reduction (Phillips, 1998). A mixture and a compound also vary on the composition of the component elements. A...

Total points for project: 45 points.
Part I. Basic Computations
1. A.) Find the future value on $6,000 in three years if the interest is compounded semiannually at 12%. (5 points)
FV = PV (1 + r)^t
FV is the future value,PV is the present value,r is the rate ,^ is to the power of and t is the time.
6000(1+0.06)^6=8511.11$
FV=8511.11$
Answer: 8511.11$
B.) What is the compound interest earned? (5 points)
Compound interest=FV-PV
8511.11-6000=2511.11$
Answer: 2511.11$

Modelling Unknown System 2...Modeling Unknown System 2 IIR filters are infinite impulse response digital filters. The filter has feedback response. It finds application where the phase linear characteristics like in speech processing signals are not required. Auto Regression process (AR) is a random process used to model and predict a variety of natural phenomena. The process finds its application both in signal processing and statistics. The AR model is a group of linear prediction formulas that predict the system’s output based on the previous outputs that are, to check the linearity of the output [1].
There are various design methods of IIR filter used, with the analogue reference prototype filter being the most commonly used method, as it is suitable... Unknown...

Unknown...Research Proposal Salem Witchcraft Trial of 1692 To make the research paper about America’s history relevant, it would make an interesting writeto delve into one of America’s darkest history. America too underwent a stage of religious fanaticism and fatalism just like her rabid critic today. This proposed research is relevant in today’s socio-political environment because her practice of freedom both in religious practice and speech offends many of its critic in today’s contemporary world yet she herself at some point were also as fatalistic as they.
The proposed research is about the Salem Witchcraft of 1692. This interesting because in 1692, witchcraft was considered a crime in the United States and anybody who is tried... Proposal...

Compound inequality...Mathematics: compound inequalities al affiliations Compound inequalities Compound inequalities must contain at least two inequalities. The two inequalities are separated by either ‘and’ or ‘or’. The graph representing a compound inequality with and constitutes the intersection of the two inequalities. A number satisfying this inequality must satisfy both the inequalities.
The graph of the compound inequalities with or represents the union of the two inequalities. A number satisfying this inequality must satisfy at least one of the inequalities. The problem at hand involves two compound inequalities. One with and, the other with or.

One Variable Compound Inequality...Given the “and” compound inequality as -4 ≤ 3 + 7x < 24, I know that the expression 3 + 7x is both less than 24 and greater than or equal to -4. To arrive at a solution set for ‘x’,
-4 ≤ 3 + 7x < 24 First, 3 must be subtracted from each of the three parts
-4 - 3 ≤ 3 + 7x - 3 < 24 - 3
--- -7 ≤ 7x < 21 Then, each part must be further divided by 7 to isolate ‘x’ in the middle,
--- -7/7 ≤ (7x)/7 < 21/7 which simplifies to -1 ≤ x < 3 (in algebraic form).
By interval notation, this solution set may be expressed as intersection [-1, +∞) ∩ (-∞, 3) giving [-1, 3) with graphical representation... :

Unknown... of your Paper Sub Paper Due What defines a "good" villain? What qualities does a bad guy need to possess in order for us to "love to hate" them? Choose a specific example of a villain and show how they fit your definition. (Examples: "A good villain must be clever, amoral, and inventive. A perfect example of such a villain would be The Joker from Batman.")
When thinking of villains, there are many names which might pop into our minds; Lex Luthor, Green Goblin or Magneto to name a few. But when one thinks of the most insane and terrifying villain of all times, the Joker from the Batman series is definitely at the top of the list. A villain is the epitome of insanity and cruelty. And there is none crueler or more insane, than... of your Paper...

Simple and Compound Interest...Simple and Compound Interest Introduction Interest is an amount paid for utilization of borrowed money. A borrower pays interest to the lender for credit or any other comparable liability. In other words, interest happens to be charge for a privilege of borrowing cash. Borrowing is important in everyday life since it is a source of funding that facilitates undertaking of projects. Important examples of interest in real life include interest pain on bank loans, bond yields, as well as return on savings. The difference between interest and profit is that profit is yield as a result of investment (to an owner) while interest is paid to a lender. This paper looks at the differences between the two basic interest types:...
