simplify the expression below and state the value of m for which the simplified expression is not defined 2m² + m - 15/ m² - 9
Answer:
The simplified expression is: [tex]\frac{2m-5}{m-3}[/tex]The simplified expression is undefined for m=3Explanation:
The given expression is:
[tex]\frac{2m^2+m-15}{m^2-9}[/tex]
The numerator can be siplified by using factorization and denominator will be simplified using the formula
[tex]a^2-b^2 = (a+b)(a-b)[/tex]
So,
[tex]= \frac{2m^2+6m-5m-15}{(m)^2-(3)^2}\\=\frac{2m(m+3)-5(m+3)}{(m-3)(m+3)}\\=\frac{(2m-5)(m+3)}{(m-3)(m+3)}\\=\frac{2m-5}{m-3}[/tex]
A fraction is undefined when the denominator is zero. In order to find the value of m on which the simplified fraction will be undefined we will put denominator equal to zero.
So,
[tex]m-3 = 0 => m = 3[/tex]
Hence,
The simplified expression is: [tex]\frac{2m-5}{m-3}[/tex]The simplified expression is undefined for m=3Which of the following are picture adjustments that can be made to images?

Edit your solution from the previous array height problem by adding additional code that increases the value of the element at (0,2) by a value of 3, and then reprints the array
Expected Output
[[16, 17, 14], [17, 18, 17], [15, 17, 14]]]
[[16, 17, 17], [17, 18, 17], [15, 17, 14]]]
Answer:
height = []
height.append ([16, 17, 14])
height.append ([17, 18, 17])
height.append ([15, 17, 14])
print(height)
height[0][2] = height[0][2] + 3
print (height)
Explanation:
hope this helps!
The height problem is a sequential program and does not require loops, iteration and conditions.
The additional code segment that adds 3 to the element at (0,2) is:
height[0][2] = height[0][2] + 3
To reprint the array, we make use of the following print statement:
print (height)
So, the complete program is as follows:
height = []
height.append ([16, 17, 14])
height.append ([17, 18, 17])
height.append ([15, 17, 14])
print(height)
height[0][2] = height[0][2] + 3
print (height)

Jason has decided to use his name on all the images to protect them from misuse. He has also decided to use the logo of his company across all
the images to be extra sure about its protection in the digital world. Select the phrases or sentences that describe the two types of watermarking
options has he used to get the results.
Types of Watermarking Options
Jason wants to tag his name or logo somewhere on the image, preferably in the corner of the photo. He uses an online editing tool to add his
name at the corner of the image. He can prevent misuse of his Images online by adding a watermark over the image. Text watermarking
involves adding the imageer's name at the corner of the image. This is usually done with the help of online editing tools or software. In this form
of watermarking, he can use the logo of his company over the image to protect his identity.
Just to be sure, Jason also uses tiled watermarking, which involves placing his company logo in a pattern spread across the image. First, he
creates a copy of the original. This is to make sure that the watermarked version is saved separately. If needed, he can always access the
original image. Then he opens the logo that he wants to use as the watermark, coples It, and pastes it onto a new layer, above the image. He
turns down the opacity of the layered image. Then he merges the layer to join the watermark with the image.

To use
as an effective note-taking tool, students should write or type thoughts, questions, or ideas on them while reading.
Answer:
B. Sticky notes
Explanation:
To use sticky notes as an effective note-taking tool, students should write or type thoughts, questions, or ideas on them while reading.
What are effective notes taking?You remain awake because of it. Using words compels you to pay attention and enables you to be recognized for your greatness (or at the same time as analyzing a textbook).
It makes analysis possible. According to studies on studying, actively engaging with the material by listening and then summarizing what you hear will help you comprehend and remember the details later. Effective note-taking causes information to be recalled better.
It will be easier to remember the information for the test if you repeat the information more frequently in specific formats, such as note-taking or flashcards. Checks can be another way of remembering things.
Therefore, students should type or write down their thoughts, questions, or ideas on sticky notes while reading in order to use them as an efficient note-taking tool.

1 Which of the following could work as bits for a binary system?
А The flip sides of a coin
B The fingers on one hand
C The days of the week
D The colors of the rainbow
What is missing in the following program?
count = 0
1for numA < 3:
count = count + 2
print(numA)
answer:
Answer:
Replace for with while or if
Explanation:
The question has been answered by you before posting. However, I'll help with the explanation.
In python, for is used to iterate through a particular range. So, the for statement as used in the given program is incorrect.
Now, with what do we replace for?
The function of the program is not stated. So, I'll answer with likely options.
1. Replace for with while:
This will repeat the code in the while block as long as the condition numA<3 is true
2. Replace for with if statement:
This checks if numA is true and performs the operations in the [if] block.
The representation would be:
if numA < 3:
count = count + 2
print(numA)
After either of the above has been implemented, variable numA has to be initialized properly before the program functions well.
Answer:
The answer is while. Have a wonderful safe day.

La sección de lectores de un diario de la ciudad impone como única restricción para la publicación de las cartas, que el texto debe ser de 1500 caracteres. ¿Cuál será el tamaño en KB de un archivo txt que contenga ese texto?
Answer:
El tamaño de un archivo .txt que contenga esa cantidad de texto será de 1.46 KB.
Explanation:
Se entiende que todo caracter informático posee un tamaño de 1 byte, con lo cual en total el texto no puede superar los 1,500 bytes de tamaño.
Ahora bien, un kilobyte es una unidad de medida informática superior, que se compone de 1,024. Por lo tanto, dado que 1,500 - 1,024 es igual a 474, el tamaño del archivo será de 1 KB y 474 bytes. Así, para calcular el tamaño total del archivo en KB, se debe realizar el siguiente cálculo:
1,024 = 1
474 = X
((474 x 1) / 1,024) = X
0.46 = X
Así, el tamaño de un archivo .txt que contenga esa cantidad de texto será de 1.46 KB.
