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.

the answer to your question is minor arc.

the answer is $4.45. i started by figuring out the cost of the plates and napkins. the easiest way to figure this cost out is through the tax. we know the way they found the tax is by multiplying the cost of non-food items by the tax rate (5% or 0.5). so, all we have to do to find the cost before tax is set up an equation and work this formula backwards. the equation is 0.19=0.05x where x is the cost of the plates and napkins. now all you do is divide both sides by 0.05 to come up with 3.8=x. now that we know the cost of the plates and napkins is $3.80, all we have to do is subtract this cost from the total cost of $8.25 giving us the cost of the watermelon which is $4.45.
