Calculator

junlongsun 16

I have a Casio FX-9750GIII

I can't seem to get the equation solver to work, I'm mainly afraid of something similar to Chapter T8 appearing on states.

$y^2=1025-40x$
$x^2=1025-50y$

Does anyone with the model know how to get the calculator to solve the equation above?

Thanks

Camp Conway acceptance

fossasor 9

Hello! I've just been accepted into Camp Conway, but I'm not sure how popular this camp actually is, given that it's new. Has anyone else applied/has been accepted/is going? (I'm trying to figure out to what degree this acceptance was just lack of qualified applicants, so I can better predict my chances of getting into my preferred math camp.)

My MATHCOUNTS journey + I need advice

nitride 21

So I don't really care if I dox myself but I went to one of the single worst chapters in all of Florida, the Indian river chapter(even the runner of mathcounts states was sayin we would lose to osprey in states). I don't exactly know what my score is, but all I know is that I got 1st place sprint and chapter but then sold CD. If I had to guess, my score was around the 30-37 range. I also mocked at around a 70 on amc 10. My questions are:
1.
What are my chances of me getting nats qual
2.
Should I study the day before the competition

Any help? I think I am misunderstanding this.

MTA_2024 2

The problem quotes as following:
"Each point in the plane is colored either red, green, or blue.
Prove that there exists a rectangle whose four vertices are the same color."
BUT IT SAYS "EVERY POINT IN THE PLANE" SO THIS THING IS INFINITE. SO EVERY SINGLE POSSIBLE POLYGON CAN BE DRAWN. OR IS THAT WHAT WE ARE TRYING TO PROVE.
HELP ME PLEASE !!!!

Elementary Problem Set

mathnerd_101 5

1. Compute the expected number of ways to rearrange any subset of {3,4,8}.

2. Find the number of paths from (3,4) to (4,8) in the Cartesian plane.

3. Imagine a world where H, M, G, U, T, and S are the only characters in the alphabet. How many "words" of non-zero length can you form?

4. ILikeMath113's tutor has realized that he made a mistake! He now wishes for ILikeMath113 to compute what $a \cdot b$ is given that $\gcd{(a,b)} = 2$ and $\text{lcm{(a,b)}} = 174.$ What is the answer to ILikeMath113's tutor's problem?

5. Denote the distance between Carvard and NIT to be $D.$ When M decides to drive his Car from Carvard to NIT, he is hit with a BOATis-load of traffic and takes 348 minutes to arrive. However, when he drives on the way back from NIT to Carvard in his Car, he laughs at those who are trying to commute to NIT since they are stuck in traffic, and he is driving at a normal speed. It ends up taking him 187 minutes. Given that M's Car follows the TMMH principle, please compute the percent of his typical speed that M had to decrease due to traffic.

6. On Valentine's Day, baby hamster asks baby spamster to be his valentine. However, since baby hamster must travel to baby spamster's house, he decides to use his eco-friendly wheel of radius 2 inches to travel. Given that it takes baby hamster 348 revolutions to arrive at baby spamster's house, calculate the amount of distance between baby hamster and baby spamster's houses. Please give your answer in the proper units.

7. In continuation with the previous problem, baby spamster said yes! Baby hamster is so excited to finally not be single, and decides to go to Notsob with baby spamster because he is definitely not sobbing tears of joy! The flight is projected to take 843 minutes from Doowhgielar to Notsob. Given that it takes baby hamster approximately 3 seconds to say "xooks rbo sus" and baby spamster approximately 4.8 seconds to say "xooks rbo sus," working together, how many times can the new couple say "xooks rbo sus" together in the duration of the flight, while also making all the other babies on the plane mad in the process?

8. Compute the integral $\int_{0}^{\sqrt[4]{3}} \frac{2x}{1+x^4} dx$

9. Baby hamster has decided to write six essays for baby spamster: a Valentine's Day-themed love letter to baby spamster, an essay on the beauty of integrals, the mathematics behind diffusion models, entropic methods in combinatorics, the beauty of the number 348, and why xooks and xoinks should be added to the dictionary. How many ways are there for baby spamster to order these six beautiful essays in a row on the wall, given that she wants the article on the beauty of 348 and and love letter to baby spamster to be on the ends?

10. During a very average day in English class, baby hamster decides to unofficially change his name to babyhamster. Now, there are fewer ways for babyhamster to rearrange his name. Calculate the difference between the number of ways that you can rearrange "baby hamster" and "babyhamster", and denote this difference as $D.$ Furthermore, Baby Spamster seems very bored, and decides to write SpamsterHamster on her blank sheet of paper 50 times. After 50, she runs out of room and can only write Spams. Denote the probability that babyhamster (formerly known as baby hamster) randomly selects a character and selects the letter A to be $p.$ Find $\dfrac{D}{p}.$

If you cannot tell, I am currently in English class having finished by Valentines Day-related essay.

I have to keep plugging in mine to recharge it, even when I’m not using it for a few days.

Square of a rational matrix of dimension 2

loup blanc 7

The following exercise was posted -two months ago- on the Website StackExchange; cf.
https://math.stackexchange.com/questions/5006488/image-of-the-squaring-function-on-mathcalm-2-mathbbq
There was no solution on Stack.

-Statement of the exercise-
We consider the matrix function $f:X\in M_2(\mathbb{Q})\mapsto X^2\in M_2(\mathbb{Q})$ .
Find the image of $f$ .
In other words, give a method to decide whether a given matrix has or does not have at least a square root
in $M_2(\mathbb{Q})$ ; if the answer is yes, then give a method to calculate at least one of its roots.

find the isomorphism

nguyenalex 10

I have the following exercise:

Let $E$ be an algebraic extension of $K$ , and let $F$ be an algebraic closure of $K$ containing $E$ . Prove that if $\sigma : E \to F$ is an embedding such that $\sigma(c) = c$ for all $c \in K$ , then $\sigma$ extends to an automorphism of $F$ .

My attempt:

Theorem (*): Suppose that $E$ is an algebraic extension of the field $K$ , $F$ is an algebraically closed field, and $\sigma: K \to F$ is an embedding. Then, there exists an embedding $\tau: E \to F$ that extends $\sigma$ . Moreover, if $E$ is an algebraic closure of $K$ and $F$ is an algebraic extension of $\sigma(K)$ , then $\tau$ is an isomorphism.

Back to our main problem:

Since $K \subset E$ and $F$ is an algebraic extension of $K$ , it follows that $F$ is an algebraic extension of $E$ . Assume that there exists an embedding $\sigma : E \to F$ such that $\sigma(c) = c$ for all $c \in K$ . By Theorem (*), there exists an embedding $\tau : F \to F$ that extends $\sigma$ . Since $F$ is algebraically closed, $\tau(F)$ is also an algebraically closed field.

Furthermore, because $\sigma(c) = c$ for all $c \in K$ and $\tau$ is an extension of $\sigma$ , we have
$K = \sigma(K) \subset K \subset \sigma(E) \subset \tau(F) \subset F.$
This implies that $F$ is an algebraic extension of $\tau(F)$ . We conclude that $F = \tau(F)$ , meaning that $\tau$ is an automorphism. (Finished!!)

Let choose $F = A$ be the field of algebraic numbers, $K=\mathbb{Q}$ . Consider the embedding $\sigma: \mathbb{Q}(\sqrt{2}) \to \mathbb{Q}(\sqrt{2}) \subset A$ defined by
$a + b\sqrt{2} \mapsto a - b\sqrt{2}.$ Then, according to the exercise above, $\sigma$ extends to an isomorphism
$\bar{\sigma}: A \to A.$ How should we interpret $\bar{\sigma}$ ?

New Forums Duplicates

k1glaucus 3

Summary of the problem: In the New Forums collection, many of the forums are duplicated, although some have slightly different information (likely due to the forum being edited by its admin(s)). Typically only one of the two has threads, and I believe this is the only way to access
Page URL: https://artofproblemsolving.com/community/c74_new_forums
Steps to reproduce:
1. Go to the link
2. You should see duplicates of some forums
Expected behavior: Each forum appears once
Frequency: Every time
Additional information: Typically only one of the two has threads, and from creating forums in the past I believe this is the only way to access the duplicate. Also not all of the forums are duplicated. Another reason to suspect these are duplicates are the forums with similar names have the same admin.

Somehow I broke the unique contest collection naming...

Equinox8 0

Somehow I broke the unique contest collection naming scheme; for what it's worth, I also ran into an AJAX timeout error while trying to make this particular post collection for the first time, and pressed "create" twice.

Not sure if there's anything to be done here, but are there potentially unforeseen consequences here?

Search function in private messages not working

WisteriaV 2

For the past while, the search function in private messages hasn’t been working. Whenever I search for anything, it says, “No topics here!” after trying to load for a while. I’ve tried different devices (laptop and ipad) and browsers (chrome on both devices, safari on ipad, and microsoft edge on laptop), and the results are the same. I’ve also had friends say the same happens for them.
