So remember that terms are groups of numbers and variables separated by + and - , and the degree of a polynomial is determined by the total power of the greatest term.

Starting with the first question, the correct answer is B. 3rd degree polynomial with 2 terms. The total power of the greatest term (2x^3) is 3, which makes it 3rd degree, and there are 2 terms (2x^3 and -4).

Now the second question's correct answers are A and D. To write a polynomial in standard form, you just need to combine like terms and rearrange the terms so that it's in descending order of degree. And this polynomial has two terms, 3x^4 and -1.

Let the total number of teachers be x

Given:

The ratio of the number between male and female teachers is 5:9

Then the number of female teachers is 81

So 9/14*x=81

or, x=81/9*14

or, x=9*14

Therefore x=126

So the total number of teachers is 126.

Hence the number of male teachers =

5/14*126

=5*9

=45

Hence, the number of male teachers is 45.

natali 33 [55]

Answer:

Step-by-step explanation:

OMG! Don't do that! I am so sorry this is happening to you. Look I don't know how to comfort you. IF he keeps doing this tell your mom or litterally call 911. If he did it just on that day then try confronting him on it. And ask him why he did that! Don't self-harm you deserve so much more than that! You are awesome!

Write an Equation using the following arithmetic sequence: 5, _____, ______, 32

Shalnov [3]

Answer:

The sequence is:

5, 14, 23, 32

Step-by-step explanation:

We know that an Arithmetic sequence with a₁ and the commo difference 'd' has the nth term such as:

aₙ = a₁ + (n-1)d

Given the arithmetic sequence

5, _____, ______, 32

here:

a₁ = 5

n = 4

aₙ

so substituting a₁ = 5, n = 4 and aₙ = 32 in the nth term

aₙ = a₁ + (n-1)d

32 = 5 + (4-1)d

32 = 5 + 3d

3d = 32-5

3d = 27

divide both sides by 3

3d/3 = 27/3

d = 9

Therefore, the common difference: d = 9

Determining the 2nd term:

Using the formula

aₙ = a₁ + (n-1)d

substitute n = 2, a₁ = 5, d = 9

a₂ = 5 + (2-1)9

a₂ = 5 + 1(9)

a₂ = 5 + 9

a₂ = 14

Determining the 3rd term:

Using the formula

aₙ = a₁ + (n-1)d

substitute n = 3, a₁ = 5, d = 9

a₃ = 5 + (3-1)9

a₃ = 5 + 2(9)

a₃ = 5 + 18

a₃ = 23

Thus, the sequence becomes:

5, 14, 23, 32
