O preço dos produtos agrícolas oscila de acordo com a safra de cada um: o mais baixo no período da colheita, mais alto na entressafra. Suponha que
o preço aproximado P, em reais, do quilograma de tomates seja dado pela função
P(t) = 0,8 sen[(2pi/360) (t - 10)]+ 2, 7, na qual t é o número de dias contados de
1 de janeiro até 31 de dezembro de um determinado ano. Para esse período de tempo,
calcule:
(a) o maior e o menor preço do quilograma de tomates
(b) os valores t para os quais o preço P seja igual a R$ 3,10.
