Rebbeca Marie Gomez (born March 2, 1997), better known by her stage name Becky G, is an American singer, songwriter, rapper, and actress. Her musical style is an integration of pop-rap and Latin pop music genres. She gained recognition in 2011, after she posted several videos of herself performing remixes of popular songs on to YouTube. In 2014, Gomez had her first Billboard Hot 100 entry, with "Shower", peaking at No. 16.
Gomez is of Mexican descent. Financial struggles forced her family to sell their home and move into the converted garage of her grandparents' house in Inglewood when she was nine years old. Gomez wanted to earn money to help out her family, so began working part-time jobs. Jobs she had included voice-overs and commercials. She also began recording herself in Garageband. Gomez has cited Christina Aguilera, Thalía and Jennifer Lopez as her musical influences.
Prior to becoming solo, Gomez used to be part of the girl groups called G.L.A.M. starting in 2009 and later in BCG.
A Problem is an obstacle which hinders the achievement of a particular goal, objective or purpose.
Problem(s) or The Problem may also refer to:
A mathematical problem is a problem that is amenable to being represented, analyzed, and possibly solved, with the methods of mathematics. This can be a real-world problem, such as computing the orbits of the planets in the solar system, or a problem of a more abstract nature, such as Hilbert's problems.
It can also be a problem referring to the nature of mathematics itself, such as Russell's Paradox.
Informal "real-world" mathematical problems are questions related to a concrete setting, such as "Adam has five apples and gives John three. How many has he left?". Such questions are usually more difficult to solve than regular mathematical exercises like "5 − 3", even if one knows the mathematics required to solve the problem. Known as word problems, they are used in mathematics education to teach students to connect real-world situations to the abstract language of mathematics.
In general, to use mathematics for solving a real-world problem, the first step is to construct a mathematical model of the problem. This involves abstraction from the details of the problem, and the modeller has to be careful not to lose essential aspects in translating the original problem into a mathematical one. After the problem has been solved in the world of mathematics, the solution must be translated back into the context of the original problem.
The Matrix is a science fiction action media franchise created by The Wachowski Brothers and distributed by Warner Bros. Pictures. The series began with the feature film The Matrix (1999), and continued with two sequels, The Matrix Reloaded (2003) and The Matrix Revolutions (2003). The characters and settings of the films are further explored in other media set in the same fictional universe, including animation, comics, and video games.
The series features a cyberpunk story incorporating references to numerous philosophical and religious ideas where the heroes fight a desperate war against machine overlords who have enslaved Humanity in an extremely sophisticated virtual reality gestalt. Other influences include mythology, anime, and Hong Kong action films (particularly "heroic bloodshed" and martial arts movies).
Two of the Matrix video games, both supervised by the Wachowskis, are a part of the official chronology. Enter the Matrix, mainly focused on Niobe and Ghost and also written by the Wachowskis, connects the story of the short animated film Final Flight of the Osiris with the events of Reloaded, while The Matrix Online is a direct sequel to Revolutions.
Matrix is the title of a Canadian-produced fantasy/adventure series that ran for 13 episodes during 1993 on the USA Network in the United States. The series later enjoyed a brief revival of interest due to a coincidence involving one of its stars.
The series starred Nick Mancuso as Steven Matrix, a hitman who is killed during a job and sent to a version of Purgatory called The City In-Between. There he is given a choice: to be sent to Hell for all the murders he's committed, or return to Earth and help people. Once alive again, Matrix receives periodic assignments from The City In-Between.
In 1999, Carrie-Anne Moss became popular for her appearance in the film The Matrix, which had no relationship to the television series apart from its title and Moss' involvement. As a result, however, Matrix was rebroadcast in Canada.
Science-fiction veteran David Winning directed an episode entitled "False Witness" in 1993.
A formula of the predicate calculus is in prenexnormal form if it is written as a string of quantifiers (referred to as the prefix) followed by a quantifier-free part (referred to as the matrix).
Every formula in classical logic is equivalent to a formula in prenex normal form. For example, if ,
, and
are quantifier-free formulas with the free variables shown then
is in prenex normal form with matrix , while
is logically equivalent but not in prenex normal form.
Every first-order formula is logically equivalent (in classical logic) to some formula in prenex normal form. There are several conversion rules that can be recursively applied to convert a formula to prenex normal form. The rules depend on which logical connectives appear in the formula.
The rules for conjunction and disjunction say that
