$$4\sqrt 3$$
#### Work Step by Step
We can use the product rule for square roots to rewrite the radicand as the product of a perfect square factor and another factor: $$\sqrt 48 = \sqrt (16 \times 3)$$ Because $16$ is a perfect square factor, we can take the square root of $16$, which is $4$: $$4\sqrt 3$$

# Definition:Tangent Bundle
Let $X$ be a differentiable manifold.
The tangent bundle of $X$ is the disjoint union of all the tangent spaces as the base point ranges over the entire manifold:
$\displaystyle T \left({X}\right) = \coprod_{x \mathop \in X} T_x \left({X}\right)$

# Factor by taking out the greatest common factor - Factoring Polynomials
### Factor by taking out the greatest common factor
To factor means to take out a common factor out from the expressions. In this lesson, we will try to do it by determining the greatest common factor among the terms of the expressions, and factor it out from each term.

# Sum of the squared least squared residual
#### brothers10
##### New Member
Hey guys!
This is my first post on this booming forum!
I came across a problem that asks "Find the Sum of the squared least squared residual" and All it gives is sigma squared hat and the population and I have searched through the book and I have no idea where to start or what formulas to use. I was hoping that someone could give me some guidance about where to start.Thank you in advance!

Less than half of the easy-to-sell assets that underpin major US banks’ liquidity adequacy requirements sit within their balance sheets’ available-for-sale (AFS) perimeter, Risk Quantum research has found. In a seeming mismatch between practice and theory, the divergence may come under scrutiny if the liquidity coverage ratio (LCR) framework is re-examined in the wake of Silicon Valley Bank’s collapse.

Q5. If X and Y are two sets such that X has 40 elements, X $\cup$ Y has 60 elements and X $\cap$ Y has 10 elements, how many elements does Y have?
S seema garhwal
n( X $\cup$ Y) = 60
n( X ∩ Y) = 10
n(X) = 40
n( X $\cup$ Y) = n(X) + n(Y) - n( X ∩ Y)
n(Y) = 60 - 40 + 10
n(Y) = 30
Hence,set Y has 30 elements.

# Graph Layout: Fixed node locations
I'm aware of a large amount of literature on the problem of graph layout. Usually this involves taking a list of nodes and edges, and choosing locations and paths for both respectively. Are there any algorithms that take graphs where the node locations are already known, and produce paths for the edges?

Suppose a function f(x) has domain (-\infty,\infty) and range [-11,3]. If we define a new function g(x) by g(x) = f(6x)+1, then what is the range of g(x)? Express your answer in interval notation.

$$f(6x) \text{ has the same range as }f(x)\\ f(6x)+1 \text{ shifts the range of }f(x) \text{ 1 unit in the positive direction }\\ \text{so that the range of }g(x) = f(6x)+1 \text{ is } [-10,4]$$

You can control the position of an image using options for the figure environment, e.g. the [h!] in the example below tells LaTeX to put the figure exactly where it appears in the text, instead of letting it 'float' to a particular place in the document.
\begin{figure}[h!]

# Calc1.85
Say we have a rectangle of length $a$ and height $b$. We know that the area is given by the simple formula $A=ab$ but now that we know calculus we can derive this formula and many others. Set up the rectangle so that it is completely in the first quadrant but has one edge against the x-axis and another up against the y-axis. Then the area can be found by an integral
$A=\int _{{0}}^{{a}}b\,dx=bx{\bigg |}_{{0}}^{{a}}=b(a)-b(0)=ab\,$

# Category:Square-Free Integers
This category contains results about integers which are square-free.
Let $n \in \Z$.
Then $n$ is square-free if and only if $n$ has no divisor which is the square of a prime.
That is, if and only if the prime decomposition $n = p_1^{k_1} p_2^{k_2} \ldots p_r^{k_r}$ is such that:
$\forall i: 1 \le i \le r: k_i = 1$

Maybe the impact of this is not significant, but here is the image (I used MS Edge, 200% for the image):
I inspected the elements, and both link and flag use -apple-system,BlinkMacSystemFont,"Segoe UI","Liberation Sans",sans-serif as fonts. For history, the font used is Arial.
I want to ask if this is intentional or not.

# Question #9f2d5
Jun 25, 2017
#### Answer:
$K N {O}_{3} \to {K}^{+} + N {O}_{3}^{-}$
#### Explanation:
Solvation takes place since this is an ionic compound, and it dissolves into its constituent ions. Water is omitted for simplicity; no reaction really takes place per se (nothing cool!).

# Solution to system of linear equations in range of system matrix
by kalleC
Tags: equations, linear, matrix, range, solution
P: 39 Hint: Ask yourself whether $A^T y = 0 [/tex] has solutions such that [itex] y^T b \neq 0$. Try it yourself first. Then if you think you know what is going on, look at the wikipedia entry under Fredholm alternative.

## Introductory Algebra for College Students (7th Edition)
When adding $\frac{1}{5}$ and $\frac{3}{4}$, there are many common denominators that we can use, such as 20, 40, 60, and so on. The given denominators, 4 and 5, divide into all of these numbers. However, the denominator 20 is the smallest number that 4 and 5 divide into. For this reason, 20 is called the least common denominator.

#### Answer
$x=\frac{3y}{4}$
#### Work Step by Step
We are given the equation $2x+3y=6x$. To simplify, subtract 2x from both sides. $4x=3y$ Divide both sides by 4. $x=\frac{3y}{4}$

# Isobutene IUPAC naming [closed]
What is the correct name of an isomer of isobutene $\ce{C4H8}$: 1,1-dimethylethene or 2-methylprop-1-ene? I have done an exam recently and I'm just curious about what what would be correct.

# Irreducible components of the space of foliations of degree three on $\mathbb P^3$
We show that the space of foliations of degree three on $\mathbb P^3$ has at least 28 distinct irreducible components,
some of them being generically non-reduced. This is a joint work with Raphael Constant and Jorge V. Pereira.

## Algebra 2 (1st Edition)
In the given polynomial of degree $3$, there are $3$ zeros. Here, we have $g(x)=-x^3+5x^2+12$ By Descartes' Rule, we have $1$ positive real root. Now, $g(x)=-(-x)^3+5(-x)^2+12=x^3+5x+12$ The above polynomial shows that there is no sign change. By Descartes' Rule, we have no negative real root. Thus, the other two roots must be imaginary. Hence, positive real root =1 Negative real root= 0 Imaginary roots: 2

Counting Sign Changes in the Prime Number Theorem
The prime number theorem tells us that the number of primes up to x is asymptotic to li(x), the logarithmic integral function. But which is greater, pi(x) or li(x)? Littlewood showed that the function pi(x) - li (x) changes sign infinitely many times, and a great amount of work has gone towards finding the first sign change. For this talk, we will focus instead on the average density of sign changes, improving on a method due to Kaczorowski.

There’s an image of some trees here. I bet the image contains more than trees, though. trees.png
Hint:
Try mod 8?
## Write-up
Stegsolver is very useful for this, as we take a look at the plane 2s.
If you squint hard enough, you can barely make out the flag.
Therefore, the flag is dont_miss_the_flag_for_the_trees.

Back in March, when we had a few nice days, quite a few of my potted lilies decided to grow. They got to between 4 - 7 inches in height, nice bushy leaves on top. Then came the snow and very, very hard frosts with wind chill. Most of the tops are now wilted, mushy and not at all well. does anyone think they will produce a second shoot? If so, shall I take off the dead shoot? Or have we had it for this year, or indeed for ever? Any ideas very welcome please.

(a) ${e^{-4}4^6\over 6!}$.
(b) $P(X\ge 10) =1-P(X\le 9)$ where $\lambda =8$ since this is a two week period and you expect twice as many parts used.
So, $P(X\ge 10) =1-\sum_{k=0}^9 {e^{-8}8^k\over k!}$.
(c) Here you want three 'successes' in three weeks (binomial) where p is from (a)... $\biggl({e^{-4}4^6\over 6!}\biggr)^3$.
Sorry, I do not understand (d).

# circom Compiler
circom has two compilation phases:
1. The construction phase, where the constraints are generated.
2. The code generation phase, where the code to compute the witness is generated.
If an error is produced in any of these two phases, circom will finish with an error code greater than 0. Otherwise, if the compiler finish successfully, it finishes returning 0.

# What are the foci of the ellipse x^2/49+y^2/64=1?
Mar 2, 2015
The answer is: ${F}_{1 , 2} \left(0 , \pm \sqrt{15}\right)$.
The standard equation of an ellipse is:
${x}^{2} / {a}^{2} + {y}^{2} / {b}^{2} = 1$.
This ellipse is with the foci (${F}_{1 , 2}$) on the y-axis since $a < b$.
So the ${x}_{{F}_{1 , 2}} = 0$
The ordinates are:
$c = \pm \sqrt{{b}^{2} - {a}^{2}} = \pm \sqrt{64 - 49} = \pm \sqrt{15}$.
So:
${F}_{1 , 2} \left(0 , \pm \sqrt{15}\right)$.

Figure 4 shows two arrows (or axes). One runs vertical and one runs horizontal, intersecting to make a cross. On the horizontal scale the dimension is labelled from individualism at the left hand side to communitarianism at the right hand side. On the vertical scale, the dimension is labelled from egalitarianism at the bottom to hierarchy at the top.

# Property of derivative of Dirac delta function in $\mathbb{R}^n$
With reference to Property of Dirac delta function in $\mathbb{R}^n$, is there a similar formula for $\langle g^*\delta', f \rangle$ (or even $\langle g^*\delta^{(n)}, f \rangle$)? By similar I mean a representation by an integral over $g^{-1}(0)$.

In my case all the data was in UTC so I just needed to remove the timezone to create the table. The easiest way to do that was to cast it to a timestamp (without a timezone).
cast(event_time as timestamp)

# The angle between the vectors $$(\overline{\mathrm{A}}$$ x $$\overline{\mathrm{B}})$$ and $$(\overline{\mathrm{B}}\times\overline{\mathrm{A}})$$ is:
A
00
B
1800
C
450
D
900
Solution
## The correct option is D $$180^{0}$$($$A$$$$\times$$$$B$$) = - ($$B$$$$\times$$$$A$$) which are equal and opposite in direction.Hence it will have angle in between $$180^0$$Physics

# gghighlight 0.1.0 Is Released!
## July 4, 2018 by Hiroaki Yutani
gghighlight 0.1.0 is on CRAN now!
## New features
As I’ve introduced on the previous post, gghighlight now can highlight any Geoms with gghighlight(). Since this function supersedes the previous functions, gghighlight_line() and gghighlight_point() are now deprecated.
## A Vignette
One more small news is, gghighlight got an introductory vignette. This is basically the shorter version of the previous post:

This result is included in Ore's book The Four-Colour Problem (see Theorem 7.4.3). I saw a paper that states this as a folklore result and cites Ore. Interestingly, the book gives a different proof for (ii)$\implies$(i). It seems that at that time, it wasn't known that the mapping $f\longmapsto f^*$ is a bijection.

Genius! We need to calculate all the forces along the y-direction. $$N$$ and $$m g$$ are already acting along the y-direction. For the y-component of $$F$$, we take the $$\sin$$ component. We sum them all up and set it equal to $$0$$.

# Change of basis
1. ### Norman
922
Hello all,
I need some help...
If I know the form of a wavefunction in the $S_z$ basis, say it is spin up, how do I convert that to a wavefunction expressed in the $S_x$ basis? Is there a very simple way to do this?
Thanks
2. ### Norman

Anyone???
Do I just rotate the spinor using a rotation operator?
Help?

You've basically got it. To convert from Sz to Sx, you rotate the state vector p/2 rad about the y-axis.

## Precalculus (6th Edition)
Given that we know x=1 is part of the solution set, we back-substitute it into one of the initial equations: $x+y=5$ $1+y=5\quad/-1$ $y=4$ Confirm by substituting into the first equation: $-2(1)+5(4)=18$

# Undefined to some power
If we raise some undefined quantity to some power, what type of quantity(number) is produced? Also, if we raise an undefined number to the power of some other(maybe same) undefined number,what becomes?

# Bounding values of a Dirichlet distribution
Consider $$k$$ random variables $$X_1, X_2, \ldots, X_k$$ such that $$(X_1, X_2, \ldots, X_k)$$ follow a $$\text{Dirichlet}(1, 1, \ldots, 1)$$ distribution. For a large enough $$k$$, I am trying to bound/find out (with high probability) what fraction of these $$k$$ random variables take values between $$\alpha$$ and $$\beta$$, for $$0 < \alpha < \beta < 1$$.

# Character (of a topological space)
(diff) ← Older revision | Latest revision (diff) | Newer revision → (diff)
One of the cardinal characteristics of a topological space $X$. The local character $\chi(x,X)$ at a point $x \in X$ is the least cardinality of a local base at $x$. The character $\chi(X)$ is the least upper bound of the local characters.
