Tyrel está aprendiendo sobre cierto tipo de metal que se utiliza para fabricar satélites. Aprende que la luz infrarroja es absorbida por el metal, la luz de rayos X se transmite a través del metal y la luz visible se refleja en el metal. Tyrel se pregunta si el metal se calentará si lo ilumina. ¿Puede la luz hacer que el metal se caliente? ¿Por qué o por qué no? ¿Importa qué tipo de luz incide sobre el metal?

The second largest public utility in the nation is the sole provider of electricity in 32 counties of southern florida. to meet the monthly demand for electricity in these counties, which is given by the inverse demand function p = 1,200 – 4q, the utility company has set up two electric generating facilities: q1 kilowatts are produced at facility 1, and q2 kilowatts are produced at facility 2 (so q = q1 + q2). the costs of producing electricity at each facility are given by c1(q1) = 8,000 + 6q12 and c2(q2) = 6,000 + 3q22, respectively. determine the profit-maximizing amounts of electricity to produce at the two facilities, the optimal price, and the utility company’s profit
