Given the sequence 31,24,17,10......
What would the 11th term of the sequence be?
The 11th term of the sequence is
Scientific Calculator

Answers

Answer:

-39

Step-by-step explanation:

This sequence follows the pattern of subtracting 7 each time. We can prove this:

31 - 7 = 24, 24 - 7 = 17, 17 - 7 = 10

So if we were to continue to the 11th term, we would subtract 7 more times.

1. 10 - 7 = 3

2. 3 - 7 = -4

3. -4 - 7 = -11

4. -11 - 7 = -18

5. -18 - 7 = -25

6. -25 - 7 = -32

7. -32 - 7 = -39

The 11th term in the sequence would be -39.

what does x equal in this equation

Answers

what’s the equation? i don’t see it?

Answer:

x=2

Step-by-step explanation:

You have to subtract 8 from both sides.

-5x+8=-2

-8 -8

----------------

-5x= -10

now divide both sides by -5.

x=-10/-5

(And two negatives make a positive.)

x=10/5

now you have to simplify 10/5

10/5 simplified is 2

so the answer is:

x=2

What is EG? (image below)

Answers

The answer of EG is 30. We can find it by Triangle Proportionality Theorem and Angle Bisector Theorem.

What is Triangle Proportionality Theorem?

According to Triangle Proportionality Theorem, A triangle's other two sides are proportionately divided by a line that runs parallel to one of its sides.

So here, [tex]\frac{DN}{NG} = \frac{DM}{ME}[/tex] (Triangle Proportionality Theorem)

⇒ [tex]\frac{30}{24} = \frac{y}{12}[/tex]

⇒ 24 * y = 30 * 12

⇒ y = 15

So, we get [tex]DE = y + 12 = 15 + 12 = 27[/tex]

The angle bisector theorem states that a triangle's opposing side is divided into two halves by an angle bisector that is proportionate to the triangle's other two sides. 

Now, we can find EG by Angle Bisector Theorem,

⇒ [tex]\frac{DG}{FG} = \frac{DE}{FE}[/tex]

⇒ [tex]\frac{54}{x+10} = \frac{27}{x}[/tex]

⇒ [tex]54x= 27 x + 270[/tex]

⇒ [tex]54x-27x = 270[/tex]

⇒ [tex]27x = 270[/tex]

⇒ [tex]x = 10.[/tex]

So, [tex]EG = x + x + 10 = 2x + 10 = 20 + 10 = 30[/tex].

So, finally we get EG = 30.

[tex]\displaystyle \log_7\frac{1}{81}\approx -2.2[/tex]

Step-by-step explanation:

We want to find:

[tex]\displaystyle \log_7{\frac{1}{81}}[/tex]

First, using the quotient rule:

[tex]\displaystyle \log_b\frac{a}{c}=\log_b a-\log_b{c}[/tex]

We can rewrite our expression as:

[tex]=\log_7 1-\log_7 81[/tex]

The logarithm of 1 is always 0. Therefore:

[tex]=-\log_781[/tex]

We can rewrite this as:

[tex]=-\log_7 9\cdot 9[/tex]

Using the product rule:

[tex]\log_b ac=\log_ba+\log_bc[/tex]

This is equivalent to:

[tex]=-(\log_79+\log_79)[/tex]

Substitute:

[tex]=-(1.1+1.1)=-2.2[/tex]
