I Uma sequência numérica é determinada conforme a lei an = n2 + 2. Essa sequência é uma progressão aritmética de razão 2.
ll Ronei contratou, durante trinta dias, um jardineiro para fazer um serviço em sua casa por 400 reais. Contudo, ao negociarem a forma de pagamento o jardineiro propôs o seguinte: em vez de R$ 400,00, gostaria de receber um pouquinho a cada dia: R$ 1,00 no primeiro dia, R$ 2,00 no segundo dia, R$ 3,00 no terceiro dia, e assim por diante, recebendo sempre a cada dia, R$ 1,00 a mais que no dia anterior. Então, ao aceitar a proposta Ronei terá um prejuízo de 65 reais.

A Onça e a libra são unidades de massa do sistema inglês. Sabe-se que 16 onças equivalem a uma libra. Considerando uma libra igual a 453,60 gramas, então, 128 onças equivalem a menos que 4 kg.
IV Um comerciante, visando aumentar as vendas de seu estabelecimento, fez uma promoção para determinado produto.
Na compra de 4 unidades desse produto o cliente leva 5 unidades para casa. Então quando um cliente compra de
oito unidades desse produto, e consequentemente leva 10 unidades para casa, estará recebendo um desconto equivalente a 25% do preço sem a promoção.
Analise as afirmações a seguir e assinale a alternativa que contém todas as corretas.
I Se a parábola definida pela função ƒ(x) = x2 + mx + 9 é tangente ao eixo das abscissas, então, o único valor que pode assumir é m = 6.
ll O conjunto Dƒ = R - {-3,3} é o domínio da função 
.
III Sejam f, g e f+g funções reais. Se f e g são funções injetoras, então, f+g também será uma função injetora
IV Se a função ƒ definida em ƒ: R - {2} → R - {a} por 
é inversível, então, a = -1.

"Many people do not wash their hands when the behavior in which they engage would warrant it," begins a recent study from Michigan State University, and I'm sorry to say it only gets grosser from there. Researchers sneakily observed 3,749 people in public restrooms and found that nearly all of them—95 percent—didn't wash their hands long enough to kill germs.
Even scarier, 15 percent of men and 7 percent of women did not wash their hands at all. When they did bother to turn on a faucet, half of men and 22 percent of women neglected to use soap! (Or, as the researchers describe it: They "attempted to wash their hands," but failed.)
The CDC says you need to wash your hands—with soap!—for at least 20 seconds in order to kill disease-causing germs.
Alas, the people in this study only washed their hands for an average of 6 seconds (...)
This extensive study founds lots of other interesting tidbits about hand-washing habits. Here are a few:
• People were more likely to wash their hands in the morning
• People were less likely to wash their hands if the sink was dirty
• People were more likely to wash their hands if there was sign to remind them
Other hand-washing research has found that college students are disgusting, people will wash their hands if they're being watched, and antibacterial soap isn't much better than the regular kind.
The study appears in the Journal of Environmental Health.

A French art expert believes a charcoal drawing kept in a collection for more than 150 years may be a preparatory sketch made by Leonardo da Vinci of the Mona Lisa.
The black-and-white drawing of a woman, nude from the waist up, known as the Monna Vanna, was previously attributed to Leonardo’s studio, suggesting it was done in his style by a pupil or follower, not by the master himself.
But after preliminary tests at the Louvre Museum, experts believe the sketch may well have been drawn by Leonardo.
Among the signs, according to curator Mathieu Deldicque, are the fact the drawing was made during the same period as the Mona Lisa, the paper is from the same region of Italy, and the technique is very similar to that of the Mona Lisa.
“We know the drawing was made during the lifetime of Leonardo da Vinci, we know that the paper was made in Italy, between Venice and Florence, and the third discovery is the high quality of this drawing in the face of the Monna Vanna and in her arms,” Deldicque told reporters.
“That’s very interesting because the arms are the same as the Mona Lisa‘s.”
Leonardo, who lived from 1452 to 1519, was an engineer, scientist, inventor and sculptor, as well as one of the finest artists of the Italian Renaissance.
He painted the Mona Lisa, also known as La Gioconda and regarded as the world’s most valuable artwork, at the beginning of the 16th century. It is believed to depict Lisa Gherardini, the wife of a successful merchant.
EXCITING
The charcoal portrait, in which the woman is holding a similar pose to the Mona Lisa but with her body more side-on and her head turned further over her left shoulder, has been held in a collection at the Conde Museum at the Palace of Chantilly, north of Paris, since 1862.
The Mona Lisa and Monna Vanna hold their hands in very similar ways, the right hand across the left and resting on the forearm, the fingers gently extended.
Deldicque said that while it was exciting to think the charcoal drawing was created by Leonardo, there were more tests to be done.
“We have one more month of analysis and then a very slow process of history of art with a collection of analysts and advice by specialists,” he said.
It is possible that process will determine that the authorship is the same. But it may also be inconclusive, he said, adding:
“Maybe the mystery will remain.”

Relacione as colunas, considerando as especificidades e os diferentes aspectos apontados relativamente à poesia brasileira, e assinale a sequência correta.
(1) O sapo-tanoeiro,
Parnasiano aguado,
Diz: – “Meu cancioneiro
É bem martelado.”
(2) Enquanto pasta, alegre, o manso gado,
Minha bela Marília, nos sentemos
À sombra deste cedro levantado.
Um pouco meditemos
Na regular beleza,
Que em tudo quanto vive nos descobre
A sábia Natureza.
(3) Negras mulheres, suspendendo às tetas
Magras crianças, cujas bocas pretas
Rega o sangue das mães:
Outras, moças... mas nuas, espantadas,
Em ânsia e mágoa vãs.
(4) Caminhando contra o vento
sem lenço, sem documento
no sol de quase dezembro
eu vou.
(5) Se eu morresse amanhã, viria ao menos
Fechar meus olhos minha triste irmã;
Minha mãe de saudades morreria
Seu eu morresse amanhã.
(6) Vai-se a primeira pomba despertada...
Vai-se outra mais .. mais outra... enfim dezenas
De pombas vão-se dos pombais, apenas
Raia sanguínea e fresca a madrugada...
( ) O tropicalismo, movimento libertário por excelência da década de 1960 no Brasil, durou pouco mais de um ano e acabou reprimido pelo governo militar.
( ) As principais características da poesia produzida por essa geração são: o individualismo, egocentrismo, o negativismo, a dúvida, a desilusão, o tédio e os sentimentos relacionados à fuga da realidade, que caracterizam o chamado ultra-romantismo.
( ) Configura a disposição dos modernistas de provocar uma ruptura com a arte do passado.
( ) O estilo parnasiano no texto beira a perfeição. O belo é a poesia com sua correção métrica gramatical, com versos decassílabos, modelo clássico de composição. O belo, o sublime e a natureza permeiam o poema.
( ) Os poetas condoreiros defendiam a liberdade e denunciavam as desigualdades sociais.
( ) Os poetas árcades veem a natureza em perfeito
equilíbrio e harmonia.
Analise as afirmações a seguir e assinale a alternativa em que todas são corretas.
l As Fantasias Eletivas, de Carlos Henrique Schroeder, inclui reproduções das fotografias que Copi fez e legou a Renê. A cada fotograma corresponde um pequeno texto que antes de falar do que está fixado pela luz conta a solidão, tristeza e dor de quem escreve.
ll O romance Quarenta Dias, de Maria Valéria Rezende, pode ser resumido assim: “Em uma pequena cidade da antiga zona do café fluminense, dois meninos de 12 anos — de classe média baixa, um filho de ferroviário, outro de açougueiro — encontram o corpo mutilado de uma linda mulher às margens de um lago onde vão fazer gazeta. Assustados, os garotos chamam imediatamente a polícia e passam por um duro interrogatório, no qual são tratados mais como suspeitos do que testemunhas”.
lll A linguagem utilizada por Conceição Evaristo é de fácil acesso e, na maioria das vezes, é culta. A obra Olhos d’Água também busca renovar a linguagem por meio da hifenização (Duzu-Querença; flor-criança; borboleta-menina; dedos-desejos; gozo-dor; águas-lágrimas) e criação de neologismos (Luamanda – formada dos vocábulos lua + manda do verbo mandar); lacrimevaginava – lacrimejar + vagina + sufixo flexional.
lV O romance As fantasias Eletivas “traz à tona vozes negras, periféricas e em contextos de grande vulnerabilidade social. Fala da banalidade da vida e de como ela se esvai entre os dedos, feito água. Nos faz entender como essas experiências ficam à margem e têm sua validade suspensa porque são constantemente silenciadas” (Carla Soares).
V O texto a seguir descreve os gêmeos da obra Esaú e Jacó, de Machado de Assis: Esaú e Jacó eram filhos gêmeos de Isaac e Rebeca. O pai, Isaac, gostava muito de Esaú, porque era bom caçador e trazia coisas para a família comer. Mas Rebeca gostava mais de Jacó, porque era um menino quieto e mansinho.
Sobre a obra Esaú e Jacó, de Machado de Assis, preencha com V a(s) afirmação(ões) verdadeira(s) e com F a(s) falsa(s) e assinale a alternativa com a sequência correta.
( ) O livro foi publicado em 1904 e a ação se desenvolve durante o período da Proclamação da República.
( ) Os protagonistas Pedro e Paulo viviam em constante antagonismo, como se observa na seguinte cena: “Iam descendo pela Rua da Carioca. [...] Pedro viu um retrato pendurado de Luís XVI, entrou e comprou-o por oitocentos réis; era uma simples gravura atada ao mostrador por um barbante. Paulo quis ter igual fortuna, adequada às opiniões, e descobriu um Robespierre”.
( ) O personagem José Dias é um agregado que "amava os superlativos", "ria largo, se era preciso, de um grande riso sem vontade, mas comunicativo... nos lances graves, gravíssimo", "como o tempo adquiriu curta autoridade na família, certa audiência, ao menos; não abusava, e sabia opinar obedecendo", "as cortesias que fizesse vinham antes do cálculo que da índole".
( ) Toda a história se desenvolve de maneira cronológica; somente aqui e ali o narrador suspende essa sequência para se referir brevemente ao pretérito, com a intenção de explicar alguns pontos não compreensíveis da narrativa. Por exemplo, em dado momento ele revela o passado do barbeiro no Navio Negreiro.
( ) O conselheiro Aires é mais um grande personagem da galeria machadiana, que reaparecerá como memorialista na obra Memorial de Aires, próximo e último romance do autor: velho diplomata aposentado, de hábitos discretos e gosto requintado, amante de citações eruditas, muitas vezes interpreta o pensamento do próprio romancista.
Nas frases a seguir, preencha as lacunas com uma das preposições sugeridas entre parênteses e depois assinale a alternativa com a sequência correta.
l Nesse caso, é estranho que o Ministro do Meio Ambiente ignore as informações técnicas _____ que detém a posse. (sobre, com, de)
ll De acordo com as fontes _____ as quais mantive contato ontem, a mudança na legislação eleitoral não valerá para 2018. (com, perante, a)
lll Quando um homem _____ quem eu confiava me disse que havia uma solução para isso, eu acreditei. (a, em, de)
lV Logo cedo chegaram dois gaúchos pilchados e um vizinho meu recente, ____ cuja procedência não me lembro. (em, de, sobre)
V Ontem resolvi mandar uma carta à empresa _____ a qual o jornal fez uma longa reportagem, publicada na semana
passada. (com, perante, sobre)
Considerando que as orações subordinadas adverbiais concessivas se opõem à ação da oração principal, mas sem impedir a sua realização, assinale a alternativa em que as duas orações entre colchetes são concessivas.
