In expanded form, 57,000 equals 50,000 + 7,000 therefore, number 60 and 4 are NOT one of the numbers that Kim wrote.
What is meant by expanded form?The expanded form of a number is the division of a number into place values, such as ones, tens, hundreds, thousands, ten thousand, and so on.
The number represented by the sum of each digit multiplied by its place value is known as its expanded form. When you write a number in expanded form, you write the value of each digit and then add them together to find the sum.
The number 1,24 has the following values, for example: it is in the thousands place, the value of one is written as 1,00. thus it is in the hundreds place, the value of 2 is written as 20.
Therefore,
Expanded Form of 57,000
57,000 = 50,000 + 7,000.
Hence, In expanded form, 57,000 equals 50,000 + 7,000.

Using the exponential function 2x + 3, what is the average rate of change between the values 1 ≤ x ≤ 5?
explain your answer step by step
Rate of change of the function: 60
Step-by-step explanation:
The exponential function in this problem is
[tex]f(x)=2^{x+3}[/tex]
The rate of change of a function between a certain interval [tex]x_1 \leq x \leq x_2[/tex] is given by
[tex]r=\frac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]
where
[tex]f(x_1)[/tex] is the value of the function calculated in [tex]x_1[/tex]
[tex]f(x_2)[/tex] is the value of the function calculated in [tex]x_2[/tex]
In this problem, the interval is
[tex]1\leq x \leq 5[/tex]
So we have:
[tex]f(x_1)=f(1)=2^{1+3}=2^4=16[/tex]
and
[tex]f(x_2)=f(5)=2^{5+3}=256[/tex]
Therefore, the rate of change is:
[tex]r=\frac{256-16}{5-1}=60[/tex]

I really don't get it can you give me the answer then explain why it is that one please
Answer:
[tex]\frac{100}{9}[/tex] is the answer.
Step-by-step explanation:
Well the first thing we would do is simplify all the exponents first inside the parenthesis. So 2^-3 is equal to 1/8. To solve negative exponents you would just divide the number instead of multiply, so 2 divided by 2 divided by 2 is equal to ⅛ or .125
Next would be to do the 2^-9. This would equal 1/512
Now would be to simplify 5^0. Anything to the power of 0 is always one. So now we simplify all the products meaning 7*5*2 and 7*3.
Now we would simplify both fractions.

What is the area of the following circle?
the diameter is 10.
Answer: The area of the circle with a diameter of 10 cm is 78.5 cm2.
Answer: 78.5 units²
Step-by-step explanation: To find the area of a circle, start with the formula for the area of a circle.
Area = πr²
Notice that here, we're given the diameter instead of the radius. It's important to understand that the radius is equal to half of the diameter so the radius of this circle will be equal to half of 10 or 5.
So plugging into the formula, we have (π)(5)².
A common mistake is to plug 10 into the formula but remember that we must plug in the radius and not the diameter.
Multiplying, (5)² is equal to 5 x 5 or 25 so we have 25π.
So the area of the circle is 25π.
Now, remember that π is approximately equal to 22/7 or 3.14 so we can estimate the area of the circle by plugging in 3.14 for π.
So we have (25)(3.14) which is equal to 78.5 units².
Since there were no labels, I just add units to the end.
So the area of the circle is approximately equal to 78.5 units².

FEET LONG. HOW TALL IS THE TREE?
Answer:
Step-by-step explanation:
25.8
6 out of 10 is 60% so 60% percent of 43 is 25.8
The height of the tree is 25.8 feet which is casting a shadow of 43 feet long.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, A tree casts a shadow that is 43 feet long, and boy cast shadow of 10 feet who is 6 feet tall.
Assuming the height of the tree to be x.
∴ 43 : 10 : : x : 6.
43/10 = x/6.
10x = 258.
x = 25.8 feet.
So, the height of the tree is 25.8 feet.

On the distant plant, Mathology, a sports area covers 7400 yodels2. How many square deckles would this be if 1 deckle = 75.9 yodels?
Answer:
It would be 97.50 square deckles.
Step-by-step explanation:
Given:
On the distant plant, Mathology, a sports area covers 7400 yodels².
1 deckle = 75.9 yodels.
Now, to get the square deckles.
As given, 1 deckle = 75.9 yodels.
So, to get the square deckles by using conversion factor:
75.9 yodels = 1 deckle.
7400 yodels² = [tex]7400\div 75.9[/tex]
= [tex]97.50\ deckels ^2.[/tex]
Therefore, it would be 97.50 square deckles.
The area is approximately 1.286 deckles².
To convert the area from square yodels to square deckles, we need to use the given conversion factor: 1 deckle = 75.9 yodels.
First, we'll find out how many yodels one square deckle is by squaring the conversion factor.
1. Calculate the area of one square deckle in yodels: (75.9 yodels)² = 5752.81 yodels².
2. Convert the given area of the sports area from yodels² to deckles²: 7400 yodels² ÷ 5752.81 yodels²/deckle² ≈ 1.286 deckles².
Therefore, the sports area covering 7400 yodels² is approximately 1.286 square deckles.
If f(1) = 7 and f(n) = f(n − 1) – 4 then find the value of f(6).
Answer:
- 13
Step-by-step explanation:
f(1) = 7
f(n) = f(n − 1) – 4
f(₂) = f(1) – 4 = 7 - 4 = 3
f(₃) = f(₂) – 4 = 3 - 4 = -1
f(₄) = f(3) – 4 = (-1) - 4 = - 5
f(₅) = f(₄) – 4 = (- 5) - 4 = - 9
f(₆) = f(₅) – 4 = (- 9) - 4 = - 13
The value of f(6) is -13, calculated based on the provided recursive formula where each term is four less than the previous.
Explanation:We are given that f(1) = 7, and the recursive equation for n is f(n) = f(n − 1) – 4. Since the equation shows that each next term is four less than the previous one, we can calculate the following iterations:
f(2) = f(2-1) - 4 = f(1) - 4 = 7 - 4 = 3f(3) = f(3-1) - 4 = f(2) - 4 = 3 - 4 = -1f(4) = f(4-1) - 4 = f(3) - 4 = -1 - 4 = -5f(5) = f(5-1) - 4 = f(4) - 4 = -5 - 4 = -9f(6) = f(6-1) - 4 = f(5) - 4 = -9 - 4 = -13So, the value of f(6) is -13.

a rectangle has a perimeter of 204 feet. Its length is six feet longer that twice its width. find the dimensions
Answer:
The length of the rectangle is 70 cm
The width of the rectangle is 32 cm
Step-by-step explanation:
Given:
perimeter of the rectangle = 204 feet
Its length is six feet longer that twice its width
To Find:
The dimensions of the rectangle = ?
Solution:
Let the width of the rectangle be x
Then its length is six feet longer that twice its width.
That is length = 6 + 2x
Now we know that the perimeter of the rectangle is
perimeter = 2(length + width)
204 = 2(6+2x+x)
204 = 2(6+3x)
204 = 12 +6x
204 - 12 = 6x
192 = 6x
x =[tex]\frac{192}{6}[/tex]
x = 32
Thus the width is 32 cm
Its length is
=6 + 2x
=6 + 2(32)
=6 + 64

ZX is the perpendicular bisector of wY, and YZ = 13.75. Find wz.
The required values are WZ = 13.75 and YZ = 27.
What is a perpendicular bisector?A perpendicular bisector is defined as a line that divides an angle into two equal angles. Draw the given angle first, then cut it in half, and then draw the angle's bisector.
As per question 1,
We have been given that ZX is the perpendicular bisector of WY
YZ = 13.75
13.75 + 13.75 = 27.5
27.5 / 2 = 13.75
WZ = 13.75
As per question 2,
We have been given that ZX is the perpendicular bisector of WY
WZ = 4n - 13 and YZ = n + 17
To find YZ
According to the property of the perpendicular bisector,
WZ = YZ
4n - 13 = n + 17
4n - n = 17 + 13
3n = 30
n = 30/3
n = 10
Substitute the value of n = 10 in YZ = n + 17
So, YZ = 10 + 17 = 27
Thus, the required values are WZ = 13.75 and YZ = 27.

Answer:
Option C: [tex]h(x)=\frac{11}{x-4}[/tex] has the same domain as [tex]$(m \circ n)(x)$[/tex]
Explanation:
It is given that [tex]m(x)=\frac{x+5}{x-1}[/tex] and [tex]n(x)=x-3[/tex]
Let us find the domain of [tex]$(m \circ n)(x)$[/tex]
[tex]$\begin{aligned}(m \circ n)(x) &=m(n(x))\\&=m(x-3) \\ &=\frac{(x-3)+5}{(x-3)-1} \\ &=\frac{x+2}{x-4} \end{aligned}$[/tex]
Now, let us equate the denominator equal to zero to determine the domain.
[tex]$x-4=0$[/tex]
[tex]x=4[/tex]
Thus, the function becomes undefined at the point [tex]x=4[/tex]
Hence, the domain of [tex]$(m \circ n)(x)$[/tex] is [tex]$(-\infty, 4) \cup(4, \infty)$[/tex]
Now, we shall find the function which has the same domain as [tex]$(m \circ n)(x)$[/tex]
Option A: [tex]h(x)=\frac{x+5}{11}[/tex]
The function h(x) has the domain of set of all real numbers [tex]$-\infty<x<\infty$[/tex]
Thus, the interval [tex](-\infty,\infty)[/tex] is not the same domain as [tex]$(-\infty, 4) \cup(4, \infty)$[/tex]
Hence, Option A is not the correct answer.
Option B: [tex]h(x)=\frac{11}{x-1}[/tex]
Equating the denominator equal to zero, the function becomes undefined at the point [tex]x=1[/tex]
Thus, the function h(x) has the domain of [tex]$(-\infty,-1) \cup(-1, \infty)$[/tex] is not the same domain as [tex]$(-\infty, 4) \cup(4, \infty)$[/tex]
Hence, Option B is not the correct answer.
Option C: [tex]h(x)=\frac{11}{x-4}[/tex]
Equating the denominator equal to zero, the function becomes undefined at the point [tex]x=4[/tex]
Thus, the function h(x) has the domain of [tex]$(-\infty, 4) \cup(4, \infty)$[/tex] is the same domain as [tex]$(-\infty, 4) \cup(4, \infty)$[/tex]
Hence, Option C is the correct answer.
Option D: [tex]h(x)=\frac{11}{x-3}[/tex]
Equating the denominator equal to zero, the function becomes undefined at the point [tex]x=3[/tex]
Thus, the function h(x) has the domain of [tex]$(-\infty,3) \cup(3, \infty)$[/tex] is not the same domain as [tex]$(-\infty, 4) \cup(4, \infty)$[/tex]
Hence, Option D is not the correct answer.

[tex]3=(\frac{3}{4}(b))+(\frac{3}{4}(-8))[/tex]
[tex]3=(\frac{3}{4} b)+(-6)[/tex] Don't know which goes into the parentheses....think the one above makes more sense...maybe....sorry
[tex]3=\frac{3}{4} b-6[/tex] Add 6 on both sides
[tex]9=\frac{3}{4} b[/tex] Multiply the reciprocal of 3/4 to get rid of the fraction and get b by itself, which would be 4/3 [basically flipping the fraction or switching the numerator and the denominator]
