Question

Recent studies indicate that the average surface temperature of a planet has been rising steadily. Some scientists have modeled the temperature by the linear function T = 0.02t + 8.25, where T is temperature in °C and t represents years since 1900. (a) What do the slope and T-intercept represent? The slope is 0.2 which means that the average surface temperature of the planet is increasing at a rate of 2 X °C per year. The T-intercept is 8.25 which presents the average surface temperature in the year 1990 (b) Use the equation to predict the planet's average surface temperature in 2030. 35.25 X °C Need Help?

Answer 1

а T= 0.02 t t 8.25 compar with y = = matc m=0.02 C = 8.25 so slope = 0.02 T- intercept , c = 18.25 b t = 2030 - 1900= 130 = T = 0.02 x 130+ 8.25 10.85 110. ol mistake is 0.2 Note : only instead of 0.02.
