Problema Solution
In 1950 the average global temperature was 57.2 degrees F. Since that year the temperature has risen at a rate of .05 percent per year. Some estimates claim that the polar ice caps could melt if the average global temperature were raised 5 degrees. If the current growth rate remains the same what year would the polar ice caps melt?
Answer provided by our tutors
Let 'x' represent the number of years since 1950 when the raise equals to 5 degrees.
57.2*(1.0005^x) = 57.2 + 5
1.05^x = 62.2/57.2
x log(1.0005) = log(62.2/57.2)
x = log(62.2/57.2)/log(1.0005)

x = 168 years approximately
1950 + 168 = 2118
The polar ice caps will melt in the year of 2118.
