Pumping Plan: Initial Invest. Annualized: $A=1\mathrm{.}4M(\frac{A}{P},10\%,40)=1\mathrm{.}4M(0\mathrm{.}1023),=$$$143,200$ Additional invest. in ${10}^{th}yr$:$A=200000(\frac{P}{F},10\%,10)(\frac{A}{P},10,40)$

$=200000**0\mathrm{.}3855**0\mathrm{.}1023=$$$7,890$

How did they calculate $($P$/$F$,10\%,10)$ and $($A$/$P$,10,40)$ to be $0\mathrm{.}3855$ and $0\mathrm{.}1023?$
