This newspaper was established in 1843 to take part in “a severe contest between intelligence, which presses forward, and an unworthy, timid ignorance obstructing our progress”. One of the chief ways in which intelligence presses forward is through innovation, which is now recognized as one of the most important contributors to economic growth. Innovation, in turn, depends on the creative individuals who dream up new ideas and turn them into reality.

The Economist recognizes these talented people through our annual Innovation Awards, presented in seven fields, including energy and the environment - whose winner is:

Stanford Ovshinsky, president and chief scientist and technologist, Energy Conversion Devices, for developing the nickel-metal-hydride battery. This is the battery technology found in hybrid cars, laptop computers and many other devices, and is just one of the many innovations devised by Mr Ovshinsky , a self-taught inventor who pioneered the field of amorphous materials in the 1950s. He is now focusing on solar panels and hydrogen-powered cars.

In paragraph 1, the author refers to innovation and its

Pedro, Paulo e Luís trabalham em uma imobiliária. No mês de junho, Pedro vendeu 2/3 e Paulo vendeu 1/6 do total de imóveis vendidos pela imobiliária. Sabe-se que, no mesmo mês de junho, Luís vendeu 6 imóveis. Com essas informações, conclui-se que, no mês de junho, o número de imóveis que a imobiliária vendeu foi igual a:

Uma operadora de telefonia celular que opera com as tecnologias TDMA e GSM cobra R$ 0,20 o primeiro minuto e R$ 0,10 o minuto adicional. Com essa tarifa, o custo de uma chamada de duas horas e 30 minutos é igual a:

Uma faculdade possui 2500 alunos dos quais 40% falam espanhol e 60% são do sexo masculino. Sabese que 25% das mulheres falam espanhol. Desse modo, o número de alunos do sexo masculino e que falam espanhol é igual a:

Calcule a área limitada pela função f(x) = ─ x² + 2x e o eixo dos x, do ponto x = 0 ao ponto x = 2.

Calcule a integral indefinida ∫ e−²^x dx.

Obtenha a função derivada de \(e^{-2x} (3x^2-2)\).

Indique o limite do quociente de sen x por x, quando x → 0.
