Hello, I'm studying for my math final next week and struggling with this problem I found online. I can't find any assistance so really need your help. if there's a way to explain how you did what you did that would be helpful. just trying to make sure I don't make any mistakes.

Exponential Modeling

Carbon dioxide (CO2) concentration in the atmosphere rose from roughly 290 parts per million in 1860 to 380 parts per million in 2010. Assume that this growth can be modeled with an exponential functionoftheformQ=Q0(1+r)t.

Task 1

By experimenting with various values of the fractional growth rater, find an exponential function that fits the given data for 1860 and 2010. you may use a calculator

Task 2

According to theRule of 70(pg. 483 of textbook), the doubling time is approximately

T_double70/r

Use your exponential model from Task 1 to predict when the CO2concentration will bedoubleits 1860 level. You may use the Rule of 70.

Task 3

Many nations have proposed or set precise goals for reductions in carbon dioxide emissions, Research the current goals of the United States. Are goals proposed in the past being met?
