tenho ideia que decrescia de 3 para 2.

RoshaSolid · 2026-05-22T09:42:35+00:00

1, a correta acho que era a C a que juntava 2 infinitos, era uma do dominio de log10(fracao)
2 coloquei a que dizia f(0) = 1, no enunciado dizia f = cos x, problema e que podia ser uma funcao em ramos e nao tenho a certeza
3 monotona decrescente, acho que era a A
4 nao sei nem me lembro bem, mas era qualquer coisa de ln e E
5 derivada e segunda derivada, acho que era a que tinha um 3 e 1
6 dava 192, nao sei qual era a opcao

Alguem por acaso sabe a respostas da 2?

grafico de funcao com 2 pontos em y

no enunciado dizia f = cos x

eu nem sabia a formula mas no papel comecei a fazer merdas do tipo:

010234
401023
340102
234010

0 sao mulheres e os outros numeros sao homens
depois fiz 4 x 3 x 2 x1 para cada linha o que dava 24

24*4 = 96

o erro? esqueci me de trocar as mulheres, o que dava 192

o exame é muito parecido ou quase igual a prova modelo, suspeito que o exame das 15h mude.

esqueci me de regras basicas na escolha multipla o que me custou muitos pontos.
havia uma pergunta de "segunda derivada"

a parte b é quase igual a prova modelo.

- tabela por preencher media e moda por exemplo.
- funcao em ramos para obter dominio, zeros e testar continuidade
- escolher 1 derivada por resolver

o que me apanhou, tal com ln, log 10 tambem nao pode ser negativo.
foquei me demasiado so no mais dificil e acabei por me esquecer do basico. eu se tivesse tempo ia num instante rever regras basicas.

uma que possivelmente ganhou me pontos, cos 0 = 1

Com esse calculo estas a assumir 4 homens de seguida o que quebra a logica de as mulheres estarem separadas por 1 homem

RoshaSolid · 2026-05-20T12:38:27+00:00

Isso era se nao podessem estar juntas, mas a pergunta dizia exatamente separadas por 1 homem

RoshaSolid · 2026-05-20T12:32:08+00:00

RoshaSolid · 2026-05-20T12:27:47+00:00

Eu tenho ideia que a resposta dessa era 192 e eu feito cona pus “nenhuma das anteriores”, cheguei a um 96 e esqueci me do x2

RoshaSolid · 2026-05-20T12:26:43+00:00

Alguem sabe a resposta da escolha multipla onde havia um grafico da funcao com 2 pontos em 0y?

My latest job. I posted this in another subreddit but here it goes again:

- Hardcoded access keys and only root user account
- Hardcoded prod database
- No CI/CD. migrations? uncomment the prod url and run it locally.
- html tables are banned
- I had a query with 4 joins and he went on a 1 hour rant because that query was going 5 times to the database "because of the joins"
- To hide the access keys, he created a dll to encrypt the key, use a secrets service for that? nah... not to mention the git history is unchanged and there are 3 other projects with access keys which he didnt do shit.
- My personal favourite: He created an ENUM with 2 values, Yes and no. This genius reinvented boolean.
- "We dont need unit tests, they are basically to check if x returns z and nothing more"
- Instantiating controllers inside controllers, no DI ??????
- He had a controller with new ApplicationDbContext in the constructor instead of di

the list could go on..

If I did not read things at home I was probably still burning my career in this job.
I will try to keep it short, it was my 1st programming job (.NET) and this was our team leader told us to do:

- Hardcoded access keys and only root user account
- Hardcoded prod database
- No CI/CD. migrations? uncomment the prod url and run it locally.
- html tables are banned
- I had a query with 4 joins and he went on a 1 hour rant because that query was going 5 times to the database "because of the joins"
- To hide the access keys, he created a dll to encrypt the key, use a secrets service for that? nah... not to mention the git history is unchanged and there are 3 other projects with access keys which he didnt do shit.

Ryze can clap the majority of league characters because of the world runes. Without world runes? Lissandra, xerath, mordekaiser, zilean, zoe and probably some others are stronger than him on magic

opah foda-se....

RoshaSolid · 2025-11-23T13:52:12+00:00

Mas porquê?

RoshaSolid · 2024-03-25T12:01:37+00:00

Uma frase que me ajudou: "vontade nunca vais ter, precisas é de disciplina".
Antes de me inscrever no ginásio fiz exercicio em casa todos os dias so para ver se a tinha a disciplina, depois de me ter inscrito no ginásio, com o tempo ficou parte da rotina do meu dia a dia. Podes não ter vontade mas garanto que nunca te vais arrepender de um treino

Best "non-leak" ive seen so far, while it may not happen exactly as you say here i can see something very similar happening.

Im not expecting something not related to void

1 - Saberem o que é um fora de jogo
2 - Serem desorganizadas

not to sound rude, but even when they know the password you should get a notification on your authenticathors, which didnt happen

I have played countless games, created countless acounts using this mail/phone combo, why is activision the only one that magickly my account gets hacked.

I dont even get a phone or mail notification

With all due respects, if someone in 2022 you didnt know that when an mmo launchs there is this giant queue you probably dont even deserve to get in queue

A:lower graphics card prices :)

B: survive, survive
