A dona de uma lanchonete observou que, vendendo um combo a R$ 10,00, 200 deles são vendidos por dia, e que, para cada redução de R$ 1,00 nesse preço, ela vende 100 combos a mais. Nessas condições, qual é a máxima arrecadação diária que ela espera obter com a venda desse combo?
A função E de Euler determina, para cada número natural ݊n, a quantidade de números naturais menores do que ݊n cujo máximo divisor comum com ݊n é igual a 1. Por exemplo, E (6) = 2 pois os números menores do que 6 com tal propriedade são 1 e 5. Qual o valor máximo de E (n), para ݊n de 20 a 25?
Se 3x2 - 9x + 7 = (x - a)3 - (x - b)3, para todo número real x, o valor de ܽa + b é
Uma agência de turismo vendeu um total de 78 passagens para os destinos: Lisboa, Paris e Roma. Sabe‐se que o número de passagens vendidas para Paris foi o dobro do número de passagens vendidas para os outros dois destinos conjuntamente. Sabe‐se também que, para Roma, foram vendidas duas passagens a mais que a metade das vendidas para Lisboa. Qual foi o total de passagens vendidas, conjuntamente, para Paris e Roma?

Assigning female genders to digital assistants such as Apple’s Siri and Amazon’s Alexa is helping entrench harmful gender biases, according to a UN agency. Research released by Unesco claims that the often submissive and flirty responses offered by the systemsto many queries – including outright abusive ones – reinforce ideas of women as subservient. “Because the speech of most voice assistants is female, it sends a signal that women are obliging, docile and eager‐to‐ please helpers, available at the touch of a button or with a blunt voice command like ‘hey’ or ‘OK’”, the report said. “The assistant holds no power of agency beyond what the commander asks of it. It honours commands and responds to queries regardless of their tone or hostility. In many communities, this reinforces commonly held gender biases that women are subservient and tolerant of poor treatment.” The Unesco publication was entitled “I’d Blush if I Could”; a reference to the response Apple’s Siri assistant offers to the phrase: “You’re a slut.” Amazon’s Alexa will respond: “Well, thanks for the feedback.” The paper said such firms were “staffed by overwhelmingly male engineering teams” and have built AI (Artificial Intelligence) systems that “cause their feminised digital assistants to greet verbal abuse with catch‐me‐if‐you‐can flirtation”. Saniye Gülser Corat, Unesco’s director for gender equality, said: “The world needs to pay much closer attention to how, when and whether AI technologies are gendered and, crucially, who is gendering them.”The Guardian, May, 2019.

Scientists have long touted DNA’s potential as an ideal storage medium; it’s dense, easy to replicate, and stable over millennia. But in order to replace existing silicon‐chip or magnetic‐tape storage technologies, DNA will have to get a lot cheaper to predictably read, write, and package. That’s where scientists like Hyunjun Park come in. He and the other cofounders of Catalog, an MIT DNA‐storage spinoff emerging out of stealth on Tuesday, are building a machine that will write a terabyte of data a day, using 500 trillion molecules of DNA. If successful, DNA storage could be the answer to a uniquely 21st‐century problem: information overload. Five years ago humans had produced 4.4 zettabytes of data; that's set to explode to 160 zettabytes (each year!) by 2025. Current infrastructure can handle only a fraction of the coming data deluge, which is expected to consume all the world's microchip‐grade silicon by 2040. “Today’s technology is already close to the physical limits of scaling,” says Victor Zhirnov, chief scientist of the Semiconductor Research Corporation. “DNA has an information‐storage density several orders of magnitude higher than any other known storage technology.” How dense exactly? Imagine formatting every movie ever made into DNA; it would be smaller than the size of a sugar cube. And it would last for 10,000 years.Wired, June, 2018. Disponível em https://www.wired.com/.
