I think I'm struggling to find the inverse for this one:
USPshnik [31]
Recall that the derivative of a constant is 0.

\bf y=x^2-4x+4\implies y=(x-2)^2\implies \stackrel{inverse}{x=(y-2)^2}&#10;\\\\\\&#10;\sqrt{x}=y-2\implies \sqrt{x}+2=y\implies x^{\frac{1}{2}}+2=y&#10;\\\\\\&#10;\cfrac{1}{2}x^{-\frac{1}{2}}+0=\cfrac{dy}{dx}\implies \cfrac{1}{2}x^{-\frac{1}{2}}=\cfrac{dy}{dx}

There are nine men and ten women in a club; in how many ways can a committee of four be formed?
DochEvi [55]
There are 19 people total, and groups of four are being asked of us. We can use the formula for permutations or combinations.

Permutations: \frac{n!}{(n-r)!}
Combinations: \frac{n!}{r!(n-r)!}
Where in both scenarios, there are <em>n</em> objects being chosen at <em>r</em> times.

19 P 4 is 93024
19 C 4 is 3876
It all depends on whether order matters with group placement; if it does, your answer is 93024, if not, then your answer is 3876.
