Hey Max....

Here is a website you might find VERY useful when you need an integral quickly:

Hey Max....you already posted these a few days ago.    There are many possible answers.    You can touch off a fire  and hold a grudge.

I'm cool with that !  Good to know the assumtions  .... Thanx !

First, let's subtract  x^1/2   from both sides to 'clean it up' a bit

1/6 - 3  = x^(1/2)   then do the math on the left side

- 2 5/6 = sqrt x

-17/6 = sqrt x     Square both sides

289/36 =x           (NOTE that 'x' has TWO sq roots   - 17/6    AND + 17/6)   

This equation only works when sqrt x = -17/6

Those are the equations I was using...With the following assumptions (since the question is a bit ambiguous)

 Assumingpt he puts in his first 5000  NOW and then every other year for 19 more deposits the result is significantly higher:

726,354.62      vs  622,732.02  (essentially two more years of compound int added to this amount)      AND if he puts in 5000 on his 65th   it would be  731,354.62   !    

Moral of the story:   Start NOW  or as soon as you can with your retirement savings/planning !!!!!!   LOL

Hi guest.....I cannot seem to get this same answer.....I assumed he would put 5000 in NOW (beginning of year 1)  and then 19 more times until he was 63....this amount would earn interest for two more years and then he would make his final 5000 payment (which would not earn interest)

Are these your assumptions?  Or did you wait two years before he made a deposit?  Did he make deposits at BEGINNING of years or END of the years ?    

Thanx !   Just trying to reconcile may calcs (my answer is higher than yours)

$1300  x  .1525/12 =  $16.52 interest this month

Correction:  I'd like to see the GIANT fox that can eat a DEER in THREE HOURS !!!!

BTW.....I'd like to see the GIANT fox that can eat a DEER in TWO HOURS !!!!

9 m 10cm  = 9.1 m   (there are 100 cm in a meter)

9.1m /  65 m x100% = 14%
