← Voltar para a lista de provas Comando da Aeronáutica · Exame de Admissão aos CFOAV, CFOINT e CFOINF 2024 65 questões nesta prova · página 2 de 4 · 64 com gabarito Gabarito disponível Gabarito disponível Função f(x)=3^(1+x)+3^(1−x) = 3(3^x+3^−x): paridade, valor em log₃(2−√3) e equação f(x)=6. f(x)=3(3^x+3^−x), e f(−x)=f(x), logo f é par. Para x=log₃(2−√3), 3^x=2−√3 e 3^−x=2+√3; a soma é 4 e f=12. Em f(x)=6 temos 3^x+3^−x=2, e pela desigualdade das médias (AM-GM) isso só ocorre com 3^x=1, ou seja, x=0 (conjunto unitário). As três são verdadeiras. A, C e D estão erradas porque as três proposições são verdadeiras; só B é coerente. Referência: Função exponencial; desigualdade entre média aritmética e geométrica. Resolução comentada do VaiConcursos. Gabarito disponível Domínio de diferença de logaritmos com base variável: base positiva e diferente de 1, e logaritmandos positivos. A base exige x+5>0 e x+5≠1, ou seja, x>−5 e x≠−4. O logaritmando x²+5x+4=(x+1)(x+4)>0 dá x−1. O logaritmando x²−1>0 dá x1. A interseção de todas as condições resulta em −5<x1. A) inclui x=1, que zera x²−1 (logaritmando deve ser > 0). B) e C) incluem o intervalo −4<x<−2, onde x²+5x+4 é negativo. D) é a única que satisfaz todas as condições.
Referência: Condição de existência de logaritmos: base positiva e ≠1; logaritmando positivo. Resolução comentada do VaiConcursos. Gabarito disponível Gabarito disponível Gabarito disponível A razão entre as alturas do cone e do cilindro é 3. Com a mesma área da base B e o mesmo volume V, o cone tem V = B·h/3, logo h_cone = 3V/B. O cilindro tem V = B·h, logo h_cil = V/B. A razão é 3. 1/3 e 2/3 inverteriam a razão ou ignorariam o fator 1/3 do cone. 1 só ocorreria se os sólidos fossem do mesmo tipo. Referência: Volumes de cone e cilindro. Resolução comentada do VaiConcursos. Gabarito disponível A probabilidade é 2·(5!)²/10!. EXCELÊNCIA tem 10 letras, com 5 vogais (E,E,E,I,A) e 5 consoantes (X,C,L,N,C). Total de anagramas: 10!/(3!2!). Favoráveis: 2 ordens dos blocos × 5!/3! × 5!/2!. Dividindo, obtém-se 2·(5!)²/10!. A, B e C erram ao ignorar o fator 2 (ordem dos dois blocos) ou ao incluir fatores indevidos, e por isso não coincidem com o resultado. Referência: Permutação com repetição e probabilidade. Resolução comentada do VaiConcursos. Gabarito disponível f⁻¹(x) = 1 − √(4 − x), logo a+b+c+d = 3. Com f(x)=ax²+bx+c e os três pontos, obtém-se f(x) = -x²+2x+3 = 4-(x-1)². Para x ≤ 1, x = 1-√(4-y), então f⁻¹(x) = 1 - √(-x+4). Assim a=1, b=-1, c=-1, d=4, e a soma é 3. As demais somas (4, 5 e 6) não resultam dos coeficientes obtidos. A escolha do ramo x ≤ 1 é o que dá b = -1 em vez de +1. Referência: Função quadrática e função inversa. Resolução comentada do VaiConcursos. Gabarito disponível O ponto de menor ordenada é (3,3), cuja soma das coordenadas é 6. Completando quadrados: (x-3)²+(y-5)²=4, com centro (3,5) e raio 2. O ponto de ordenada mínima é (3,3), e 3+3 = 6. A) Para P(4,3): 1+4 = 5 > 4, logo P é exterior. B) O quadrado circunscrito tem lado 4 e área 16, não 12. D) O triângulo equilátero inscrito tem lado r√3 = 2√3, não 3√3. Referência: Equação da circunferência. Resolução comentada do VaiConcursos. Gabarito disponível As raízes são -1, 2 e 3; o produto das duas maiores, 6, é maior que 5. Pelas relações de Girard, a soma das raízes é 4. Como uma raiz é a soma das outras duas, ela vale 2, e as outras duas somam 2 com produto -6/2 = -3, o que dá 3 e -1. As raízes são -1, 2 e 3, e o produto das duas maiores é 2·3 = 6 > 5. A) Falsa, pois -1 não é natural. B) Falsa, pois só o 2 é par. D) Falsa, pois -1, 2, 3 não formam PA (razões 3 e 1). Referência: Relações de Girard. Resolução comentada do VaiConcursos. Gabarito disponível Gabarito disponível Gabarito disponível A alternativa B contradiz o texto, que não diz que a maioria que fica morre rapidamente. O texto fala de uma escolha entre vida e morte, mas não afirma que a maioria dos que permanecem morre em pouco tempo. Essa é uma generalização sem apoio. As demais estão de acordo com o texto. A) Coerente com o texto: recomeçar se liga ao perigo e o lar seria a preferência. C) Coerente: a autora conta sua história para honrar essas pessoas. D) Coerente: ela diz que muitos não entendem que refugiados são pessoas comuns. Referência: YOUSAFZAI, We Are Displaced, 2019, p. XI. Resolução comentada do VaiConcursos. Gabarito disponível A metáfora mostra o lar como lugar ameaçador, cheio de riscos e incerteza. Ser a "boca de um tubarão" é imagem de perigo. O poema diz que só se deixa o lar quando ele se torna ameaçador, a ponto de a cidade toda fugir. A) Fala de preços e fome, o que o poema não menciona. B) Descreve o lar como lugar de alegria, o oposto da metáfora. D) A metáfora não trata de distância em relação à nova realidade. Referência: Warsan Shire, "Home", apud YOUSAFZAI, 2019. Resolução comentada do VaiConcursos. Gabarito disponível Escolher a vida significa deixar o lar porque ficar é perigoso. O texto diz que refugiados são forçados a sair por um conflito e que a escolha é entre vida e morte. Optar pela vida é, portanto, partir porque permanecer é arriscado. A) A causa é o conflito, não a pobreza. B) Aprender o idioma é consequência, não o sentido da escolha. C) Não se fala de condenação injusta por crimes. Referência: YOUSAFZAI, We Are Displaced, 2019, p. XI. Resolução comentada do VaiConcursos. Gabarito disponível Ser compreendido ajuda as pessoas a se sentirem acolhidas em um novo ambiente. O narrador diz que ser compreendido por alguém foi de enorme ajuda para se sentir confortável. Daí se generaliza que ser compreendido faz a pessoa se sentir acolhida. B) O texto mostra que gestos e sorrisos comunicam. C) Não se afirma que o passado seja crucial para aprender idiomas. D) "Never" é generalização absoluta; o texto diz apenas que, no caso dele, não foi tão difícil. Referência: BRIERLEY, Lion, 2016, p. 7-10. Resolução comentada do VaiConcursos. Gabarito disponível Saleen e Jacob ajudaram o narrador a se sentir confortável em seu novo ambiente. O casal falava hindi com ele e traduzia instruções, e o narrador diz que ser compreendido foi "a huge help in becoming comfortable about my new surroundings". A) Eles visitavam a família e comiam juntos, não cozinhavam como profissão. B) Não foram contratados; eram vizinhos conhecidos da mãe. C) O texto diz que ele falava pouco hindi e não que eles lhe ensinaram palavras novas. Referência: BRIERLEY, Lion, 2016, p. 7-10. Resolução comentada do VaiConcursos. Gabarito disponível "What I'd gone through in India" refere-se à vida difícil que ele teve na Índia. O narrador compara o que passou na Índia com a vida na Austrália e conclui que estava melhor na segunda. Isso mostra que a experiência anterior foi dura. B) O trecho trata da vida na Índia, não da viagem. C) Contradiz a comparação, que indica sofrimento. D) A adoção não é o assunto do trecho. Referência: BRIERLEY, Lion, 2016, p. 7-10. Resolução comentada do VaiConcursos. Gabarito disponível A transição foi menos difícil do que se esperaria. O texto afirma que a transição "wasn't as difficult as one might expect", pois a vida na Austrália era melhor do que a que ele tivera na Índia. Logo, foi menos difícil do que normalmente se espera. A) Contradiz o texto. B) Não diz que foi fácil como se espera, e sim menos difícil do que se espera. C) Ninguém lhe disse isso; é uma avaliação dele. Referência: BRIERLEY, Lion, 2016, p. 7-10. Resolução comentada do VaiConcursos. Gabarito disponível Apenas I e II estão corretas. I está certa: a transição "wasn't as difficult as one might expect". II está certa: ele queria muito reencontrar a mãe, mas percebeu que era impossível. III e IV não têm apoio no texto. III é falsa: os carinhos o faziam sentir seguro, amado e querido, não estranheza. IV é falsa: ele ainda se lembra da irmã Shekila e do que perdeu. Por isso B, C e D estão erradas. Referência: BRIERLEY, Lion, 2016, p. 7-10.

“no one leaves home unless
home is the mouth of a shark.
you only run for the border
5 when you see the whole city
running as well”.
Warsan Shire, “Home”.
(SHIRE apud YOUSAFZAI, 2019, p. V)
“I have had the immense privilege of meeting many
individuals who had to rebuild their lives, often in totally
foreign places. People who have lost so much - including
10 loved ones – and then had to start over. This means
learning a new language, new culture, a new way of
being. I share my story of being displaced not out of a
desire to focus on my past, but to honour the people I´ve
met and those I´ll never meet.
15 I wrote this book because it seems that too many people
don´t understand that refugees are ordinary people. All
that differentiates them is that they got caught in the
middle of a conflict that forced them to leave their homes,
their loved ones, and the only lives they had known. They
20 risked so much along the way, and why? Because it is too
often a choice between life and death.
And, as my family did a decade ago, they chose life”.
