Recent studies indicate that the average surface temperature of the earth 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 the number of years since 1900. Use the equation to predict the average global surface temperature in 2030.

Answer:

The temperature of the surface would be 9.05°C.

Explanation:

Given function that represents the average surface temperature ( in  °C ) of the earth after t years since 1990,

[tex]T=0.02t+8.25[/tex]

Since, the number of years from 1990 to 2030 = 40,

Thus, the average global surface temperature in 2030 would be,

[tex]T=0.02(40) + 8.25[/tex]

[tex]=9.05^{\circ}C[/tex]
