In either case, the expression usually suggests the unexpected or unfair use of authority in resolving a dilemma or in demanding submission. These included the sounds of marching feet, machine-gun fire, and a screaming siren. A number that represents the magnification of an optical instrument, such as a microscope or telescope.
The third power of 2 is 8. The set G is called the graph of the function. For there is no power but of God: A power microscope can magnify something times. One reason is that 2 is the first element in more than one ordered pair, 2, B and 2, Cof this set. However, the value of the new unit was chosen to make it similar to the earlier unit candlepower by dividing the Violle by Therefore, in common usage, the function is generally distinguished from its graph.
These were typically based on the brightness of the flame from a "standard candle" of defined composition, or the brightness of an incandescent filament of specific design.
Origin[ edit ] Prior tovarious standards for luminous intensity were in use in a number of countries. Compare energywork. However, some authors  reserve the word mapping to the case where the codomain Y belongs explicitly to the definition of the function.
This expression originated in the armed forces, where one of subordinate rank must comply absolutely with the orders of a superior. In the 13th CGPM removed the term "new candle" and gave an amended version of the candela definition, specifying the atmospheric pressure applied to the freezing platinum: The domain and codomain are not always explicitly given when a function is defined, and, without some possibly difficult computation, one knows only that the domain is contained in a larger set.
Thus ten to the sixth power, orequals one million. Power an abundance; a body of armed men; a fighting force; a large quantity, a great number—Johnson, Physics The rate at which work is done with respect to time, measured in units such as watts or horsepower.
The luminous intensity of light-emitting diodes is measured in millicandelas mcdor thousandths of a candela. In the definition of function, X and Y are respectively called the domain and the codomain of the function f.
When you achieve it, there is nothing there —Harold Macmillan, Parade, July 7, Like wealth and power, prestige tends to be cumulative: The term is now also applied to civilians, particularly in describing certain employeremployee interactions.
This phrase is Biblical in origin. Formally speaking, it may be identified with the function, but this hides the usual interpretation of a function as a process.
Functions are also called maps or mappings.b. The military strength or economic or political influence of a nation or other group: That country projects its power throughout the region. 2. (Mathematics) (functioning as singular or plural) mathematical operations and processes involved in the solution of a problem or study of some scientific field.
the operator of an automobile the operator of a nuclear power plant Call the operator for the phone number.
Operator, please connect me with extension She's quite an operator—no one else could have gotten them all to agree to the project. The candela (/ k æ n ˈ d ɛ l ə / or / k æ n ˈ d iː l ə /; symbol: cd) is the base unit of luminous intensity in the International System of Units (SI); that is, luminous power per unit solid angle emitted by a point light source in a particular direction.
Luminous intensity is analogous to radiant intensity, but instead of simply adding up the contributions of.
In mathematics, a function was originally the idealization of how a varying quantity depends on another quantity. For example, the position of a planet is a function of time.
Historically, the concept was elaborated with the infinitesimal calculus at the end of the 17th century, and, until the 19th century, the functions that were considered were .Download
