a constant rate in acres/year, or a constant rate as a %age of the glacier's area?
In the first case, it was reduced by 9 acres in 95 years, or .0947 acres/yr
In the second case, it was reduced to 10% in 95 years, at a rate of 2.4%/yr
I guess you want .0947 acres/yr, since it's asking for a linear equation.
A = 10 - .0947x where x=years since 1907.
Extra credit: At that rate, when will the glacier be gone?
Yes, I want the .0947 so that I could do the linear equation. Since the linear equation is A=10-.947(95)which means A = 1.0035?
I have to round the .0947 to the nearest thousandth so it would be .09?
You rounded to the nearest hundredth.
So then it is .095?
Right. 0.095
Thank you!
