The result for a sum of all interior angles for #N#-sided convex polygon is #N*180^o - 360^o = (N-2)*180^o# In #N#-sided regular polygon all #N# angles are equal, so each is equal to #((N-2)/N)*180^o# For #N=9# this gives a measure of one interior angle of a regular 9-sided polygon: #((9-2)/9)*180^o = 140^o#
The intrinsic, or gross, value of an option is the amount the option is in the money. For example, if you have the option to pay $10 per share for a stock that trades for $15, the option has an intrinsic value of $5 per share.
Earned Value is the value of the project at its current timeframe. Planned Value is the overall projected value of the project at the same time as the Earned Value. To determine the projectâs Schedule Performance Index the Project Management divides the EV by the PV. This can also be shown as a simple formula; SPI=EV/Pv. This term is defined in the 3rd and the 4th edition of the PMBOK.
