Q4176474 Matemática
A análise do comportamento geométrico de funções quadráticas revela que a existência e a natureza das raízes reais dependem diretamente da concavidade da curva e da posição de seu vértice em relação ao eixo x. Considere uma antena parabólica cujo formato pode ser modelado por uma função do tipo f(x) = ax2 + bx + c, orientada de modo que seu eixo de simetria seja vertical e o foco concentre os sinais em um ponto fixo do espaço. Sobre esse cenário, avalie as afirmações:

I. A condição para que o receptor esteja acima da abertura da parábola implica que o coeficiente a seja positivo e que o foco esteja localizado em um valor de y superior ao do vértice.
II. Caso a parábola represente uma antena cujo formato não intercepta o eixo x, conclui-se que o discriminante da equação quadrática associada é negativo, o que corresponde geometricamente a um vértice acima da linha y = 0 para a > 0.
III. III. Se o equipamento exige que todos os sinais paralelos ao eixo de simetria sejam refletidos exatamente para o foco, então a curva deve manter o mesmo coeficiente a independentemente de deslocamentos horizontais, pois tais translações não alteram a distância focal.
Diante desse contexto, pode-se afirmar que apenas:

Best Part (feat. H.E.R.)
Daniel Caesar


You don't know, babe
When you hold me
And kiss me slowly
It's the sweetest thing
And it don't change
If I had it my way
You would know that you are


You're the coffee that I need in the morning
You're my sunshine in the rain when it's pouring
Won't you give yourself to me?
Give it all, oh
I just wanna see


I just wanna see how beautiful you are
You know that I see it
I know you're a star
Where you go, I'll follow
No matter how far
If life is a movie
Oh, you're the best part, oh
You're the best part, oh
Best part


It's this sunrise
And those brown eyes, yes
You're the one that I desire
When we wake up
And then we make love
It makes me feel so nice


You're my water when I'm stuck in the desert
You're the Tylenol I take when my head hurts
You're the sunshine on my life


I just wanna see how beautiful you are
You know that I see it
I know you're a star
Where you go, I'll follow
No matter how far
If life is a movie
Then you're the best part, oh
You're the best part, oh
Best part


If you love me, won't you say something?
If you love me, won't you, won't you

MY FATHER, THE ASTRONAUT

If the moon was Europe, my father was an astronaut who died on his
     way to the moon.
My father, the failed moonwalker, blinded by space.
My father, the
     Black cosmonaut, frenzied
by thirst. My father who heard the voice of God, clear as the call to
    prayer, suspended in that dark desert.
My father who wore a spacesuit slashed by longing, spinning towards
     the vast desolate.
On a night when the angels have drawn back their wings, you may
      glimpse my father
hurtling through space, his body carried by gravity’s absence, blood
      collecting in his head,
his tears pink, gelatinous clots, unable to fall. (2022, Warsan Shire. From: Bless the Daughter Raised by a Voice in Her Head Publisher: Penguin Random house)

Q4176422 Linguística
In the comic strip, Calvin repeatedly asks his mother for permission using the modal verb “can”, proposing increasingly unreasonable actions (e.g., setting fire to his mattress, riding his tricycle on the roof). His mother denies every request with the same formulaic response: “No, Calvin.” After a series of absurd questions, Calvin finally asks for something reasonable: a cookie. The mother again refuses with “No, Calvin,” leading Calvin to conclude, “She’s on to me.”

Read the excerpt below:
“Teacher of language has received the knowledge of linguistic theory to teach language. Linguistics has been used as one of the disciplines which contribute to the theory of language teaching.
The knowledge of linguistic theory has been used as a device to help the language teacher.” Source: Middle-East Journal of Scientific Research 15 (8): Author: Ali Akbar Khansir – Applied Linguistics and English Language Teaching. The discussion emphasizes that Linguistics provides theoretical foundations that support language teachers in understanding linguistic structure, selecting methods, and developing appropriate teaching materials. It also states that the teacher’s role is not to teach theoretical linguistics, but to apply linguistic principles in the classroom. Based on these ideas, analyze the statements below:
I. The global expansion of English increasesthe need for teachers to master linguistic knowledge that supports intercultural communication and effective lesson planning.
II. It is argued that linguists and language teachers perform the same professional role, since both work directly with the scientific description of language.
III. Linguistics, although not offering ready-made teaching methods, provides theoretical principles that help teachers understand how language works and produce suitable learning materials.
IV. Applied Linguistics also includes the study of teaching methods and error-correction strategies related to language learning.
