Over the past few centuries, due in part to increasing carbon emissions, the amount of carbon dioxide in the atmosphere has been growing exponentially at an
approximate rate of 0.3% per year.
In the year 1900 there were approximately 270 parts per million (ppm) of carbon
dioxide (CO2) in the atmosphere. If this pattern continues, create and evaluate an
exponential expression to estimate how much co, will be in the atmosphere in
the year 2050. Round to the nearest whole number.

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.
