Question

Some scientists believe that the average surface temperature of the world has been rising steadily. The average surface temperature can be modeled by T = 0.02t + 15.0 where T is the temperature in degree C and t is years since 1950. (a) What do the slope and T-intercept represent? The slope represents the increase in the average surface temperature in degree C per year, and the T-intercept is the average surface temperature in 1950, or 15 degree C. The slope represents the decrease in the average surface temperature in degree C per year, and the T-intercept is the average surface temperature in 1950, or 15 degree C. The slope represents the average surface temperature in degree C per year, and the T-intercept is the increase in surface temperature in 1950, or 15 degree C. The slope represents the average surface temperature in degree C per year, and the T-intercept is the decrease in surface temperature in 1950, or 15 degree C. The slope represents the change in the average surface temperature in degree C per year, and the r intercept is the predicted surface temperature in year 2015. (b) Use the equation to predict the average global surface temperature in 2100. (Round your answer to the nearest degree.)

Explanation / Answer

a)

The slope represent the increase in the average temperatusre in oC per year, and T intercept is the average surface in 1950 or 150C

b) We have given T=0.02t+15

we put here t=2100 and we get

T=0.02*2100+15

=57
