A square room in your house has an area of 85 square feet. What is the approximate length of each side of the room?

Given :

Electronic configuration of an electron :

[tex]1s^2\ 2s^2\ 2p_x^2\ 2p_y^2\ 2p_z^2\ 3s^2 \ 3p_x^2\ 3p_y^2\ 3p_z^2[/tex] .

To Find :

The element having such an electronic configuration .

Solution :

We know , the sum of all the power of s and p in all the orbit gives total number of atoms in elements .

So , atomic number is :

[tex]Z=2+2+(2+2+2)+2+(2+2+2)\\\\Z=18[/tex]

Since , the atomic number is 18 .

Therefore , the element is Argon .

Hence , this is the required solution .

Answer:

23x-10

Step-by-step explanation:

Step 1- Distribute into the variable

(9)2x-3(9)+5x+17

Step 2- Collect like terms.

18x-27+5x+17

23x-10

Answer: 5

Step-by-step explanation:

The function is f(x)= -4x-3:

1) Substitute x with -2 to get: f(-2)= -4(-2)-3

2) Solve using P.E.M.D.A.S to get 8-3=5

Therefore, the answer is 5.

Answer:

y= 0.5x + 8.2

$13.6 per hour

Step-by-step explanation:

(Is it weird that I had the same exact question? Maybe not. But I also found another person with the same question as me. It was a different question though. This is probably too late. But I'm just gonna try to answer it for anyone who needs it.

"Linear regression" is just a fancy word for scatter plots. Scatter plots take place in graphs. The dots or plots are scattered and the way they are scattered means something. If it's going down, it's negative, up it's positive, and if it's scattered, it has no corrolation.

Also, you should have learned this in 9th grade. So, check your notes.

If you don't have it, WRITE IT!!!

To find it in your calculator:

1. Go to "Lists and Spreadsheets"

2. Rename the first column "x" and the second on "y"

3. Write all of your numbers in the right column

4. Move your cursor to an empty cell

4. Click: "MENU" #4 #1 #3

5. Rename the correct rows "x" and "y" and press enter

6. Now you can find "m" and "b"

7. Then move your cursor to an empty cell and click "doc" "insert" #7

8. Find the x-axis and find "x"

9. Find the y-axis and find "y"

10. Now press "MENU" #4 #6 #1

And you found your y=mx+b: y=0.5x+8.2

Now, how much money per hour.

So you've found your m and b but now you have to:

1. Replace y with 15 and solve it

Answer:

first answer is correct

Answer:

20

Step-by-step explanation:

1.4-28/x = 0

bring 1.4 to the right hand side

-28/x = -1.4

bring the x to the right hand side

-28 = -1.4x

switch the positions of -28 and -1.4x

-1.4x = -28

divide -28 by -1.4

x = -28/-1.4

x = 20

Answer:

= 192

Step-by-step explanation:

a²b²c² = 2²3²4² = (2×2)(3×2)(4×2) = (4)(6)(8) = (24)(8) = (192) = | 192 | = 192

Answer: IT IS 576

Explanation:

So, if a=2 then, 2 to the second power (squared) is 4. b(3) to the second power(squared) is 9. c (4)to the second power(squared) is 16.

One way you can remember it is if you do 1 times 1, 2 times 2, 3 times 3, and so on.

So between the answers of:

24

192

576

It would be 576

(2^2)(3^3)(4^2)=

(4)(9)(16)=

576

Answer:

[tex]\sqrt{73}[/tex]units.

Step-by-step explanation:

We have given a pentagon ABCDE

We need to calculate its length

That means we have to find the distance of AD

So, coordinates of A(1,6) and D(4,-2)

Using distance formula:

Here,

On substituting the values we will get:

On simplification:

Hence, the length of AD is   units.

Answer:

Santa can leave 15 toys at their house.

Step-by-step explanation:

f(x) = x² - 2x - 3

g(x) = 4x²

f(g(x)) = f(4x²)

f(4x²) = (4x²)² - 2(4x²) - 3

= 16x⁴ - 8x² - 3

Answer:

Step-by-step explanation:

z -  any integer

2z+1 - any odd integer (the smaller one)

2z+1+2 = 2z+3 - odd integer consecutive to 2z+1  (the larger one)

2(2z+1)    - twice the smaller number

2(2z+1) - 1    - one less than twice the smaller number

2(2z+1) - 1 = 2z + 3

4z + 2 - 1 = 2z + 3

2z = 2

 z = 1

2z+3 = 2•1+3 = 5

check:

2z+1 = 2•1+1 = 3,  

2(2z+1)-1 = 2(2•1+1)-1 = 2•3-1 = 5 = 2z+3
