First of all, know that preserved lemons will keep for quite a while in the fridge. They are preserved, after all. Kept refrigerated, these lemons will keep for about a year, so don't feel that you have to rush to use them up before they go bad.You eat the whole lemon, rind and all â though I'd recommend removing the seeds first.hey are preserved, after all.

Growth Rate in the Present Value of Stock Formula. The growth rate used for calculating the present value of a stock with constant growth can be estimated as. Multiplying the retention ratio by the return on equity can then be reduced to retained earnings divided average stockholder's equity.
Relative growth rate (RGR) is the growth rate relative to the size of the population. It is also called the exponential growth rate, or the continuous growth rate. In terms of differential equations, if is the population, and its growth rate, then its relative growth rate is. If the relative growth rate is constant, i.e., , it is not difficult to verify that the solution to this equation is.
