Answer:
all equilateral triangle’s can be mapped onto each other using dilations.
Step-by-step explanation:
Because you can dilate or increase the size and scale the triangle about a certain point so if you do it correctly, this can be done with just a dilation.
Also an equilateral triangle is defined as a triangle where all the sides are congruent in length. This does not mean that all equilateral triangles are congruent (Do not get confused with D) to each other since size is the undefined variable so all equilateral triangles are proportional which means that they always have a ratio between them depending on the scale factor.
For example, let's say I have an equilateral triangle with a side length of 2, this means that all the sides must have a length of 2, but I can also have an equilateral triangle with a side length of 3, which means that all the sides will have that length for that triangle.
2 ≠ 3, but there is always a conversion factor between the side lengths. In this case a scale factor of 3/2 from the triangle with a side length of 2 to the one with a side length of 3. And a scale factor of 2/3 going from the triangle with a side length of 3 to the triangle with a side length of 2. Because all the sides are congruent, the angles must all be 60° degrees because individual side proportions defined by trigonometry are based on angles and sides. Thus, the angles are also affected due to the change in ratio.
Determine if ƒ(x) = –x3 – x4 – 9 + 6x is a polynomial function. If it is, state the degree and the leading coefficient. If not, state why.
Answer:
The given function is a polynomial function.
The degree of the function is 4 and leading co-efficient is -1.
Step-by-step explanation:
Given function is:
ƒ(x) = –x^3 – x^4 – 9 + 6x
Putting the terms in order of their power.
[tex]f(x) = -x^4-x^3+6x-9[/tex]
A polynomial is an algebraic expression which involves only positive integer exponents for the variables.
A polynomial function is of the form:
[tex]p(x) = a_nx_n+a_{n-1}x^{n-1}+a_{n-2}x^{n-2}........ a_0[/tex]
We can see that the function has no negative exponent. So the given function is a polynomial function.
The degree of a polynomial is the highest exponent of variable involved and leading co-efficient is the co-efficient of the variable with highest power.
Hence,
The given function is a polynomial function.
The degree of the function is 4 and leading co-efficient is -1.

Simplifying
3.57x + 1.61 = 4.71 + -2.63x
Reorder the terms:
1.61 + 3.57x = 4.71 + -2.63x
Solving
1.61 + 3.57x = 4.71 + -2.63x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2.63x' to each side of the equation.
1.61 + 3.57x + 2.63x = 4.71 + -2.63x + 2.63x
Combine like terms: 3.57x + 2.63x = 6.2x
1.61 + 6.2x = 4.71 + -2.63x + 2.63x
Combine like terms: -2.63x + 2.63x = 0.00
1.61 + 6.2x = 4.71 + 0.00
1.61 + 6.2x = 4.71
Add '-1.61' to each side of the equation.
1.61 + -1.61 + 6.2x = 4.71 + -1.61
Combine like terms: 1.61 + -1.61 = 0.00
0.00 + 6.2x = 4.71 + -1.61
6.2x = 4.71 + -1.61
Combine like terms: 4.71 + -1.61 = 3.1
6.2x = 3.1
Divide each side by '6.2'.
x = 0.5
Simplifying
x = 0.5
A bell tower that is 60 yards tall casts a shadow 32 yards long. If a nearby windmill is
45 yards tall, how long will the windmill's shadow be?
Write your answer as a whole number or a decimal. Do not round.
Answer:
24 yards long
Step-by-step explanation:
60/32 = 45/x
Cross Multiply:
60x = 1440
Divide both sides by 60.
x = 24 yards

A rectangle has an area of 20 square centimeters. Which of the following could be the rectangle’s length and width?
Answer:
You did not give any options
Step-by-step explanation:
But 20 and 1 or 4 and 5 or 2 and 10 could possibly be the rectangle's length and width.
All but the first answer choice could be the length and width of a rectangle.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
A rectangle has an area of 20 square centimeters.
WE know that The area of the rectangle = length × Width
3 cm and 8 cm = 24 cm^2
This cannot be area of the given reactangle.
1 cm and 20 cm = 20 cm^2.
This is the area of the given reactangle.
2 cm and 10 cm => 20 cm^2
This is the area of the given reactangle.
4 cm and 5 cm => 20 cm^2.
This is the area of the given reactangle.
All but the first answer choice could be the length and width of a rectangle.
The complete question is
Which of the following could be the rectangle’s length and width?
1. 3 cm and 8 cm = 24 cm^2
2. 1 cm and 20 cm = 20 cm^2.
3. 2 cm and 10 cm => 20 cm^2
4. 4 cm and 5 cm => 20 cm^2.

General admission to Paul’s Pumpkin Patch is $8.00. For children to ride the various rides, they must use tickets that cost $1.00 each. The number of tickets needed for each ride varies. The function for this situation is P(x) = x + 8, where P(x) represents total cost as a function of the number of tickets, x. What is the domain for visiting and riding rides at Paul’s Pumpkin Patch? A. P(x) ≥ $8.00 B. x is all real numbers C. x ≥ 0, where x is non-negative D. x ≥ 0, x is an integer
Answer:
x ≥ 0, x is an integer
Step-by-step explanation:
Cost of general admission = $8
Cost of 1 ticket = $1
Cost of x tickets = x
So, Total cost for x tickets = x+8
We are given that P(x) represents total cost as a function of the number of tickets, x
So, P(x)=x+8
Since cost cannot be negative
So, Domain for visiting and riding rides at Paul’s Pumpkin Patch is x ≥ 0, x is an integer
So, Option D is true.
x ≥ 0, x is an integer

The hardcover version of a book weighs twice as much as its paperback version. The hardcover book and the paperback together weigh 4.2 pounds. Which system of equations can be used to find h, the weight of the hardcover book, and p, the weight of the paperback?
h = p − 4.2
h = 2p
h = 4.2 − p
p = 2h
h = p − 4.2
p = 2h
h = 4.2 − p
h = 2p
Answer:
the correct option id D.
h = 4.2 − p
h = 2p
The correct equation which can be used to find h, the weight of the hardcover book, and p, the weight of the paperback is,
⇒ h = 2p
⇒ h = 4.2 - p
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The hardcover version of a book weighs twice as much as its paperback version.
And, The hardcover book and the paperback together weigh 4.2 pounds.
Now,
Let the hardcover book weight = h
And, the paperback together weigh = p
Hence. We get;
h + p = 4.2
h = 4.2 - p
And, The hardcover version of a book weighs twice as much as its paperback version.
Hence, We get;
⇒ h = 2p
Thus, The correct equation which can be used to find h, the weight of the hardcover book, and p, the weight of the paperback is,
⇒ h = 2p
⇒ h = 4.2 - p
