Question

A major scientific periodical published an article in 1990 dealing with the problem of global warming. The article was accompanied by a graph that illustrated two possible scenarios. (a) The data might be modeled by an exponential function of the form f(x) = (4.044 x 10-38) (1.0444%). (b) The warming might be modeled by a linear function of the form g(x) = 0.009x - 17.67 In both cases, x represents the year, and the function value represents the increase in degrees Celsius due to the warming. Use these functions to approximate the increase in temperature in 2018, to the nearest tenth. (a) According to the exponential model, what is the predicted increase in temperature in 2018? The predicted increase in temperature in 2018 is about °C. (Round to the nearest tenth as needed.)

Answer 1

Given that , @ In the exponential model function is the form of the $(20 = (4.044 X 16**): ( 1.0444%) where x represents the year. : In the year 2018 " Put a =2018 in the above function. . The predicted increase in temperature in 2018 is = (4.044 X1733) · (1.04442018) °C = (4.044 x 1038)(1.18394 x1033) °c = (4.044 x 1.18394 x 15 38x1038). = (4.0 44 x 1.18394) ºc. = 4.7878°C. round to the nearest tenth. ... The Piedicted increase in temperature in 2018 is about 4. 8 °c

6 In the linear model function is 8(x) = 0.009x - 17.67 where a represents the year. here x=2018 : In the year 2018 according to linear model Predicted increase in temperature is = (0.009 X2018) -17.67 °C. = (18.162 – 17.67) °C. = 0.492°C ~0.5°C.(Round to the nearest tenth). & According to linear model, the predicted. increase in temperature in 2018 is about [0.5 °C.
