Alacarte knows to be silly sometimes, especially if you typed something after the /usr/bin/google-chrome-stable in the command field. I would suggest creating shortcut without any additional switches and then editing it "by hand".
File should be located in ~/.local/share/applications/something.desktop. Open up that file with your favorite text editor and edit line that begins with:
Exec=/usr/bin/google...

# Select all elements except the current element
Published on May 28th, 2020
If you don't want the current element to be selected in an array of elements that belongs to same class or type, just use the .not() method like the example below:
$(".btn").click(function(){$(".btn").not(this).text('selected');
});
The above code will change the text for all buttons except the current element.

# Solved – Why does \$l_2\$ norm regularization not have a square root
Specifically talking about Ridge Regression's cost function since Ridge Regression is based off of the $$l_2$$ norm. We should expect the cost function to be:
$$J(theta)=MSE(theta) + alphasqrt{sum_{i=1}^{n}theta_i^2}$$
Actual:
$$J(theta)=MSE(theta) + alphafrac{1}{2}sum_{i=1}^{n}theta_i^2$$
Contents
Also, minimizing $$MSE$$ subject to $$|theta|_2le c$$ is equivalent to minimizing $$MSE$$ subject to $$|theta|_2^2le c^2$$.

# Thread: Determine the coordinates of the point
1. ## Determine the coordinates of the point
Show that the line $
5x+3y+ \lambda x
$
= $
2 \lambda y -6
$
always passes from a fixed point . Determine the coordinate of the point.
2. The equation can be written as
$\lambda(x-2y)+5x+3y+6=0$
Then $\left\{\begin{array}{ll}x-2y=0\\5x+3y=-6\end{array}\right.$
Now solve the system.

There is a bug for the trial version: when you start it up, because of my special encoding (to prevent reverse engineering), you need to click Continue; however, if you click Quit, you need to start the program again. Just click continue!

If the area is (x-3)/(x-2) and the length is 9x-3x^2, then the width is (x-3/(x-2) divided by 9x-3x^2.
$$\frac{\frac{x-3}{x-2}}{9x-3x^2}=\frac{x-3}{\left(x-2\right)\left(9x-3x^2\right)}=\frac{x-3}{\left(x-2\right)\cdot \:3x\left(3-x\right)}=-\frac{1}{3x\left(x-2\right)}$$

## Elementary Algebra
It takes 2$\frac{1}{4}$ seconds to download 1 song, which is equal to $\frac{9}{4}$ seconds. To download 16 songs, we multiply the time needed for 1 song by 16. So, $\frac{9}{4}$ $\times$ 16 = $\frac{9 \times 16}{4}$ Factor the numerator and the denominator: $\frac{9\ \times\ 4\ \times 4}{4}$ = Cancel the common factors in the numerator and the denominator to obtain: 9 $\times$ 4 = 36 seconds

# Application of the Uniform limit theorem
Calculus Level 2
For $n\in \mathbb{N}$, let $f_n:[0, \pi]\to \mathbb{R}$ be defined by
$f_n(x):= \sin^n (x)$
Is the sequence $\{f_n\}_{n=1}^{\infty}$ uniformly convergent?
Hint: is the limit function continuous?

# Cartesian product
The Cartesian product of two sets A and B is the set (usually denoted by A × B) consisting of all ordered pairs (a, b) where $a \in A$ and $b \in B$. The Cartesian product is named after René Descartes, who invented this concept.
A common example of a Cartesian product is the coordinate plane, $\mathbb{R}^2$. This is all ordered pairs (a,b) of real numbers a and b. It is used for graphing functions on the real numbers.

### Formalizing a Proof that e is Transcendental
Bingham, Jesse; Intel Corporation
We describe a HOL Light formalization of Hermite's proof that the base of the natural logarithm e is transcendental. This is the first time a proof of this fact has been formalized in a theorem prover.

The length of a side of a square is $5x+2$ units. If the perimeter is $48$ units, complete the following.
1. Write an equation to represent this information.
To find the perimeter, add the side lengths. In this case we have a square which has four equal side lengths.
One possibility is $4(5x+2)=48$.
2. Solve for $x$.
$x=2$
3. What is the area of the square?
Remember to substitute $x=2$ back into the original equation.

Category:Quotient Groups
This category contains results about Quotient Groups.
Let $G$ be a group.
Let $N$ be a normal subgroup of $G$.
Then the left coset space $G / N$ is a group, where the group product is defined as:
$\paren {a N} \paren {b N} = \paren {a b} N$
$G / N$ is called the quotient group of $G$ by $N$.

# Selection rules for Hydrogen
temp050505
Good afternoon,
Does the selection rules have a condition on $\Delta n$ ? I have not found a website or a book that show transitions between $2S_{1/2}$ and $2P_{3/2}$, that's why I was wondering if $\Delta n = 0$, with respect to the other selection rules, are allowed transitions.

# Configuring the Server
Many application scenarios require specific server configurations. The default server options can be adjusted accordingly.
## Multi IO
The number of audio inputs and outputs can be defined before booting the server. Especially in multichannel applications - like in spatial audio - this is necessary:
s.options.numInputBusChannels = 16;
s.options.numOutputBusChannels = 48;
// boot with options
s.boot;
// show all IO channels

# [NTG-context] t-bib and explicitly italizising title parts
Hello,
Is there any way using '\it' in the title of a bib-entry, so that
ConTeXt/t-bib will hand it though into the bibliography listing?
I have a lot of publications in my lists that contain species names in there
titles, which are by convention typeset in italics.
Thanks for any hints,
Joh

QUESTION
# What is the mass of one mole of water?
18 grams
The mass of one mole of any atom/molecule is equal to its atomic molecular mass in grams.
The molecular formula of water is H_2O
The atomic mass of H = 1
The atomic mass of O = 16
In a sense, the formula means H + H + O
So... 1 + 1 + 16 = 18
Therefore, the mass of one mole of water = 18 Grams

## 2.3 Bar Charts
Bar charts are a useful way to graphically present categorical data.
If preferred, bar charts can display relative frequencies instead, as follows:
It is worth noting that the shape of both charts looks exactly the same. The difference is in the scale on the $$y$$ (vertical) axis: in the second chart, it represents percentages rather than frequencies.

# How do I simplify and find the product of 5d^2r and 3d xx 4d^3?
Jul 21, 2017
Add the indices of any like bases.
#### Explanation:
To multiply in algebra you simply ADD the exponents of the same variables.
$5 {d}^{2} r$ cannot be simplified on its own.
$3 d \times 4 {d}^{3} = 12 {d}^{4}$
If these two expressions were meant to be multiplied together the product would be:
$5 {d}^{2} r \times 12 {d}^{4} = 60 {d}^{6} r$

# From the top of a building 40 m tall, a ball a thrown vertically upwards with a velocity of $10\; ms^{-1}$ After how long will the ball hit the ground?
$\begin{array}{1 1} 4s \\ 3s \\ 2s \\7s\end{array}$
$s= -40 m, u= +10 ms^{-1} ,a=-10 ms^{-2}$
Now $s= ut+ \large\frac{1}{2}$$at^2 => -40 -10t+\large\frac{1}{2}$$\times (-10) t^2$
=> $r^2-2t -8 =0$
=> $(t+2) (t-4) =0$
=> $t=-2 \;or\; 4 s$
The negative value of t is not possible
Hence the ball will hit the ground after 4 s

## AntiMatter 4 years ago How does external torque produce angular acceleration about the center-of-mass?
1. kirill
$dL/dt=r \times F$ where L is an angular momentum $L=I \omega$ and $I$ is moment of inertia, $\omega$ is an angular velocity, $\tau = r \times F$ is a torque. So, if you differentiate $\omega$ you get angular acceleration. $I$ is a matrix in general.
2. panos
$\tau = r \times F = I \alpha$ where $I$ is is moment of inertia, where $\alpha$ is angular acceleration

# Caught In A Circle
You are trapped in the center of a flat circular area of radius 1000 by an evil maniacal tyrant. You have to walk out by taking steps of size 1. However, for each step, you can only choose the direction to walk in, and the tyrant will dictate if you move in the positive or negative direction.
What is the minimum number of steps you need to take to guarantee that you can reach the circumference?

REPORTS > KEYWORD > SHERALI-ADAMS RELAXATIONS:
Two graphs with adjacency matrices $\mathbf{A}$ and $\mathbf{B}$ are isomorphic if there exists a permutation matrix $\mathbf{P}$ for which the identity $\mathbf{P}^{\mathrm{T}} \mathbf{A} \mathbf{P} = \mathbf{B}$ holds. Multiplying through by $\mathbf{P}$ and relaxing the permutation matrix to a doubly stochastic matrix leads to the notion of fractional isomorphism. We show ... more >>>

$25x^2$
When we raise a term inside parentheses to a power, we must raise each part of the term to that power, and then multiply. Therefore, $$(5x)^2=5^2\cdot x^2=25\cdot x^2=25x^2$$

# Difference between revisions of "Polynomial ring"
Given a (commutative) ring $R$, the polynomial ring $R[x]$ is, informally, "the ring of all polynomials in $x$ with coefficients in $R$."
$$R[x]=\left\lbrace\sum_{i=0}^\infty a_ix^i\mid a_i\in R\right\rbrace$$

To find the average speed of the car, train, and boat, you divide the total distance traveled by the time it took to travel that distance. This will give you the distance traveled per unit of time. In this case, km per hr (km/hr) Car: $\frac{\text{360 km}}{\text{6 hr}}=60$ km/hr Train: $\frac{\text{400 km}}{\text{8 hr}}=50$ km/hr Boat: $\frac{\text{375 km}}{\text{5 hr}}=75$ km/hr The fastest average speed was 75 km/hr, which was the boat.

# Question #9628d
Apr 10, 2016
${\left(\frac{P V}{T}\right)}_{1} = {\left(\frac{P V}{T}\right)}_{2}$ is applicable in all situations.
Combining the relationships of each of the other general laws, ${\left(P \frac{V}{T}\right)}_{1} = {\left(P \frac{V}{T}\right)}_{2}$ is applicable in all situations.

## Area of the region
Find the area of the region inside the circle
$$r=24 cos \theta$$ and to the right of the vertical line $$r=6 sec \theta$$
• Anonymous commented
Plz.. rate me first..!!!
• R=24 cos theta
R=6 sec theta
24 cos theta =6 sec theta
cos theta=1/2
theta=60 degree
Hence using this put in formula
A = ? [b,a] (1/2)((r_1)^2 - (r_2)^2) dx

@resize(t:tab, int)
resizes its first argument and returns the results. The argument is modified. If the second argument is smaller that the size of the first argument, it effectively shrinks the first argument. If it is greater, undefined values are used to extend the tab.

# ECHO...ECHo...ECho...Echo...echo...
The Grand Canyon is anywhere from $$6$$ to $$30~\mbox{km}$$ across. If you stood on one side of the Grand Canyon at its narrowest point and shouted, how long in seconds would it take for you to hear your echo?
Details and assumptions
• The speed of sound is roughly $$350~\mbox{m/s}$$.

## Sifnab Group Title Im having a problem Integrating dx/(2+x^(1/2)) When i used U substitution u^2=x and 2udu=dx i got 2udu/(2+u) but i realy dont know what to do now? one year ago one year ago
• This Question is Open
1. adamshai Group Title
Try to substitute: $y = 2 + \sqrt{x} \\ dy = \frac{1}{2\sqrt{x}}dx = \frac{1}{2(y-2)}dx$
2. Sifnab Group Title
yes! I solved it now, thanks! That last step when you changed x^1/2 to (y-2) helpt a lot :D
