For f(x) = x8 /9 -x17 /9 find the critical numbers.


Solution:
Since f¢(x)= ---------- we see that f¢(x)=0 if x= ------- and that f¢( --------) does not exist.

Therefore, the critical numbers are --------- and ----------

I'm trying to describe the sound you hear when a vehicle passes another on the highway, something like "whoosh," and on the racetrack like "vroom."

I feel like a little sheepish asking, but I need to do a presentation for a client and his minions, and I don't want to stammer through it.

Right now I'm describing it as, "you know that sound that one car makes when it passes another car?"

Thanks for your help.

I realize that this same general question could be asked about any conspiracy theory, but the persistence of certain conspiracy theories makes more sense than others. For example, the "JFK second gunman" conspiracy theory is probably persistent because some people who opposed U.S. foreign policy during the Cold War WANT to believe that the CIA of the 1960s was corrupt and out of control. And some people believe in “9/11” conspiracies because they WANT to believe that the Bush Administration is corrupt and imperialistic, or perhaps some people NEED to believe that a good Muslim like Osama ben Laden is not capable of such a crime in order to avoid a crisis of faith.

But what’s up with the moon? Is it really so hard for some people to accept that the United States is capable of doing something so monumental that they will go to such incredible lengths to bury their heads in the sand and ignore the obvious evidence?
