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.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
