(adsbygoogle = window.adsbygoogle || []).push({}); 1. It is estimated that x years from now the value of an acre of farmland will be increasing at the rate of [tex]\frac{0.4x^3}{sqrt(0.2x^4+8000)}[/tex] dollars per year. If the land is worth 500 per acre, how much will it be worth in 10 years?

2. Use integral

Since the the function of money of time is the integral of the rate given, i integrated the function 0.4x

^3/sqrt(0.2x^4+8000)....The answer therefore represents D(t) (Dollar Vs. Time)... Then I substitue 10 years into the function, I got how much is it worth in 10 years. but the question is, whats the use of the detail "now its worth 500 per acre"? should i add 500 to the answer i have now???? thanks!
