What has a specific length? (It can’t be point C because points have no length.)

Apply the WOP to [latex]y[/latex], not [latex]x[/latex]. First, however, show that there does not eixst any positive integer [latex]x[/latex] such that [latex]1=1+x[/latex]. For this you can make use of the axiom that 1 is not the successor element of any positive integer.

One application would be in computing compound annual growth rates.

Here’s another hint: If the circle is tangent to the x-axis, the quadratic equation in [latex]x[/latex] must have a repeated root.

Some news about the “Higgs-like” particle discovered at CERN last year. That particle may indeed be a Higgs boson. http://www.newscientist.com/article/dn23265-mystery-boson-earns-higgs-status-thanks-to-w-particle.html Nonetheless, as pointed out in the article, it is only a Higgs boson, not the Higgs boson. So, can be there more than one Higgs boson? If so, what’s the difference between different Higgs bosons?
