A majorette in a parade is performing some acrobatic twirlingsof her baton. Assume that the baton is a uniform rod of mass 0.120 kg and length 80.0 cm.
With a skillful move, the majorette changes the rotation ofher baton so that now it is spinning about an axis passing throughits end at the same angular velocity 3.00 rad/s as before. What is the new angularmomentum of the rod?

Make use of vectors to re-write the following second order differential equation into a 1st order differential equation. (note: I do not need to solve it).

2.1 x^{- 2} \frac{d^{2} y}{{d x}^{2}} - 3 e^{2 x} y^{4} \frac{d y}{d x} = - 6 y

y = 4.2

\frac{d y}{d x} = - 3.1

x = 0.5

.
Im not sure were to begin any help is greatly appreciated.

A political pollster selects a random sample of 75 registered voters from Allegheny County, Pennsylvania. The city of Pittsburgh is in Allegheny County. The pollster is interested in determining if the distribution of political party preference among registered voters in this county differs between those who live in Pittsburgh and those who live in the suburbs. The responses are displayed in the table.

The pollster would like to know if these data provide convincing evidence of a relationship between residential status and political party in the population of all registered voters in Allegheny County. The random and 10% conditions are met, and this table of expected counts shows that all expected counts are at least 5.

Graphing functions with calculus
I am stuck on graphing

y = (x - 3) \sqrt{x}

I am pretty sure that the domain is all positive numbers including zero. The y intercept is 0, x is 0 and 3.
There are no asymptotes or symmetry.
Finding the interval of increase or decrease I take the derivative which will give me

\sqrt{x} + \frac{x - 3}{2 \sqrt{x}}

.
Finding zeroes for this I subtract

\sqrt{x}

and then multiply by the denominator

2 x = x - 3

.
This gives me 3 as a zero, but this isn't correct according to the book so I am stuck. I am not sure what is wrong.

Finding new stable superheavy elements is big interests in nuclear physics.
Nuclides with

Z > 92

are not found in nature, but can be made artificially.
Usually these nuclides become more unstable as their atomic number increases.
But, the island of stability predicts there are some stable isotopes of superheavy elements.
My question is why finding stable superheavy element is important?
Is it just for academic curiosity? Or is there some important application?
