Why is a general formula for Kostka numbers "unlikely" to exist?
A general formula for $K_{λ μ}$ exists, where $K_{λ μ}$ is the number of semistandard Young tableaux of shape $λ$ and type $μ$ with $λ ⊢ n$ and $μ$ a weak composition of $n$ .

L'Hôpital's rule exercise with natural log function
I'm looking for some advice on the following exercise:
$lim_{x \to 0^{+}} {\ln (\frac{1}{x})}^{x}$
This is my work so far:
$lim_{x \to 0^{+}} {\ln (\frac{1}{x})}^{x} = lim_{x \to 0^{+}} x \cdot \ln (\frac{1}{x}) = lim_{x \to 0^{+}} \frac{\ln \frac{1}{x}}{\frac{1}{x}}$
Taking the derivatives of the top and bottom:
$\frac{d}{d x} \ln \frac{1}{x} = - \frac{1}{x} and \frac{d}{d x} \frac{1}{x} = - \frac{1}{x^{2}}$
So:
$lim_{x \to 0^{+}} \frac{- \frac{1}{x}}{- \frac{1}{x^{2}}} = lim_{x \to 0^{+}} \frac{x^{2}}{x} = lim_{x \to 0^{+}} x = 0$
Which doesn't quite add up. I'm thinking, I should rewrite the equation in the form of $e^{x}$ as the limit would then approach $1$ , which is the correct answer. However, I'm a bit stuck on that front.
Any suggestions would be greatly appreciated!

A ball is thrown vertically upward from the ground. Its distance in feet from the ground in t seconds is s equals negative 16 t squared plus $176 t s = - 16 t^{2} + 176 t$ After how many seconds will the ball be 448 feet from the ground?

Dependent differential equations
So I have been working with these differential equations that are dependent on each other:
$\begin{aligned} \frac{d y}{d t} & = 0.1 y - 0.01 (10000 - a) \\ \frac{d a}{d t} & = 0.1 a - 10 y \end{aligned}$
So the first equation represents the change rate of predatory fish while the other equation is a representation of small fish.
My question is: is there a way to find a general solution for these equations, say in form of an exponential function? And what does that factor 0.01 in the first equation stand for, having 10000 as the population of the small fish at the beginning?

Energy can neither be created nor destroyed i.e. the total energy of the universe remains constant; however, it transforms from one form to another. The same phenomena apply when we burn a candle, chemical energy of wax is converted to light energy and heat energy. True or false

Here is where you have to work with the challenges that usually go beyond the high school curriculum. Take a look at the various questions to see what is studied by the advanced level Physics problems. Some of them are related to engineering, while others will deal with equations for Geology, Astronautics, Data Science, Nursing, and many other aspects of our daily life. We also offer advanced physics problem and answers that are interdisciplinary as you can learn from the solutions. Take your time to find your subject and read through the tips that are offered by your fellow students.
