Explanation

The set of positive integers is commonly referred to as the natural numbers or counting numbers

It is denoted by the symbol N or Z+.

This set includes all whole numbers greater than zero: 1, 2, 3, and so on. 

Explanation

$$lim_{x to a} (2x + 4)$$

Assuming the question meant:

lim​ x→3 ​(2x+4)

Then:

$$lim_{x to 3} (2x + 4) = 2(3) + 4 = 6 + 4 = 10$$x→3 (2x+4)=2(3)+4=6+4=10

Explanation

She has a big red ball

In English, when using multiple adjectives, we typically follow this order:

Opinion → Size → Age → Shape → Color → Origin → Material → Purpose + Noun

So in this case:

big = size

red = color

Correct order: "big red ball"

Explanation

Explanation

If $f(x) = 5$, then what is$f'(x)$ at $x = 1$?

This is a constant function, meaning:

$$f(x) = 5 quad text{for all } x$$

The derivative of a constant is always:

$$f'(x) = 0$$

Explanation

Use "whom" when it's the object of the verb or preposition.

In this sentence, the person is receiving the book (object of the verb give), so "whom" is correct

Verb: give

Subject: You

Object: whom

Explanation

 The property used in the equation a + r = r + a is the commutative property of addition.

This property states that the order in which numbers are added does not affect the sum.

In other words, if you have two numbers, 'a and 'r', adding 'a' to 'r' will result in the same answer as adding 'r' to 'a'. 

Explanation

They’re going to the party."

وہ پارٹی میں جا رہے ہیں۔

They’re = They are  (contraction)

There = refers to a place or to introduce a sentence (e.g., There is a dog.)

Their = possessive pronoun (e.g., Their car is red.)

Theres =  not a standard word (should be there's = there is)

Explanation

 "They go to the same school."

"They" is a plural subject, so the correct verb form is "go", not "goes" (which is used with singular subjects like "he," "she," or "it").

Additionally, "the" is missing before "same school."

Explanation

The transpose of a row matrix is a column matrix.

Similarly, the transpose of a column matrix is a row matrix.

In essence, when transposing a matrix, you swap rows with columns.

So, a matrix with one row becomes a matrix with one column, and vice versa.
