Atmospheric Carbon Dioxide Refer to Exercise 55. The carbon dioxide content in the atmosphere at Barrow. Alaska, in parts per million (ppm) can be modeled by the function
C(x) = 0.04x2 + 0.6x + 330 + 7.5 sin 2πx,.
where x - 0 corresponds lo 1970. (Source: Zeilik. M. and S. Gregory. Introductory Astronomy and Astrophysics. Brooks/Cole.)
(a) Graph C in the window [5. 50] by [320.450].
(b) What part of the function causes the amplitude of the oscillations in the graph of C to be larger than the amplitude of the oscillations in the graph of L in Exercise 55, which models Hawaii?
Atmospheric Carbon Dioxide At Mauna Loa, Hawaii, atmospheric carbon dioxide levels in parts per million (ppm) were measured regularly, beginning in 1958. The function
L(x) = 0.022x2 + 0.55x + 316 + 3.5 sin 2πx
can be used to model these levels, where x is in years and x = 0 corresponds to 1960. (Source: Nilsson, A., Greenhouse Earth. John Wiley and Sons.)
(a) Graph L in the window [ 15.45] by [325. 385].
(b) When do the seasonal maximum and minimum carbon dioxide levels occur?
(c) L is the sum of a quadratic function and a sine function. What is the significance of each of these
