Question
Some scientists believe that the average surface temperature of the world has been rising steadily. They have modeled the temperature by the linear function T = 0.02t + 8.65, where T is temperature in °C andt represents years since 1900.
(a) What do the slope and T-intercept represent?
The slope is
|, which means that the average surface temperature of the planet is---Select-- v at a rate of
°C per year. The T-intercept is
which presents the average surface temperature in the year
(b) Use the equation to predict the average global surface temperature in 2090.
