- Global temperature increases are benchmarked to the average temperature between 1951 and 1980. In 2010, the global average temperature was 0.72°C above the benchmark. In 2020, it was 1.02°C above.1 1climate.nasa.gov, accessed March 23, 2021. (a) Assuming the difference between the global average temperature and the benchmark is a linear function of time, find a formula for this function. The increase in average global temperature, G, above the benchmark average in the year t is given by G = i i )t eTextbook and Media (b) Use this formula to predict the difference in 2027. °C The formula predicts that in the year 2027, the average global temperature will have increased by over the benchmark.arrow_forwardThe revenue for Google for the years 2010–2014 is shown in the following table (Wallstreet Journal, August 2014).

Show that 95% of the radioactive nuclei originally present in a sample will disintegrate within three mean lifetimes, i.e., by time t=. Thus, the mean life of a k nucleus gives a quick way to estimate how long the radioactivity of a sample will last. ..... - kt If 95% of a sample has decayed, there is 5% remaining. How can you use the radioactivity equation y(t) = yo e to find when 5% of the sample is remaining? A. Set y(t) equal to 0.05 and solve for t. B. Evaluate y(0.05). C. Set y(t) equal to 0.05y, and solve for t. D. Evaluate y(5). Perform the operation determined in the previous step.
