A polygon can grow from one-dimensional objects, which are lines. Zero-dimensional objects, which are points or vertices, also play a role as they define the positions where lines meet, but a polygon cannot directly grow from three-dimensional objects because polygons are two-dimensional shapes.
Explanation:A polygon can grow from one-dimensional objects, specifically from lines. In geometric terms, a polygon is a two-dimensional shape that is formed by connecting straight line segments. Each line segment connects to two others to form the polygon's perimeter. Moreover, the line segments join at their endpoints, known as vertices, which are zero-dimensional objects that contain only a single coordinate pair.
The formation of a polygon from lines is analogous to constructing a shape on a piece of paper by drawing lines that connect to form a closed loop. In this process, the lines are the sides of the polygon, and the points where the lines meet are the vertices. It is not possible for a polygon to directly grow from three-dimensional objects, as polygons are inherently two-dimensional.
For example, to represent a soccer ball in a simplified manner such as in geographic information systems (GIS), we can use polygons in the shape of pentagons and hexagons. The soccer ball itself is a three-dimensional object but the representation involving pentagons and hexagons is a two-dimensional schematic, emphasizing the importance of polygons in various mapping and modeling applications.
The equation 9(u – 2) + 1.5u = 8.25 models the total miles Michael traveled one afternoon while sledding, where u equals the number of hours walking up a hill and (u – 2) equals the number of hours sledding down the hill. Which is the value of u?
Answer:
2.5
Step-by-step explanation:
Given: The equation [tex]9(u - 2) + 1.5u = 8.25[/tex]models the total miles Michael traveled one afternoon while sledding.
To Find: Which is the value of u?
Solution:
[tex]9(u - 2) + 1.5u = 8.25[/tex]
[tex]9u - 18+ 1.5u = 8.25[/tex]
[tex]10.5u = 8.25+18[/tex]
[tex]10.5u =26.25[/tex]
[tex]u =\frac{26.25}{10.5}[/tex]
[tex]u =2.5[/tex]
Hence the value of u is 2.5

What are the common factors of 30 and 300?
What is the negative reciprocal of 3/4 or three over 4
Final answer:
The negative reciprocal of 3/4 is -4/3. This is found by inverting the fraction to get 4/3 and then applying the negative sign.
Explanation:
The negative reciprocal of a number refers to the value that, when multiplied by the original number, results in -1. For the fraction 3/4 (three over four), taking the reciprocal involves flipping the numerator and the denominator, which gives us 4/3. Making this reciprocal negative results in -4/3. The concept of reciprocals relates to the broader mathematical principles of multiplication and division, where negative exponents indicate the inverse of the corresponding positive exponent. For example, x to the power of -1 is equal to 1 divided by x to the power of 1, which demonstrates how negative exponents introduce division into the operation.
HELP ME ASAP!! Some red white and blue candies were placed in a bowl. Some contain nuts, and some do not. Suppose one of the candies were chosen randomly from all the candies in the bowl. According to the table below, if the candy is blue, what is the probability that is does not contain any nuts?
Red with nuts=10. Red without nuts=10. White with nuts=20. White without nuts=10. Blue with nuts=20. Blue without nuts=30.
A. 20%
B. 40%
C. 60%
D. 10%
Answer:
Option C: 60%
Step-by-step explanation:
The number of blue candies with nuts = 20
The number of blue candies without nuts = 30
The total number of blue candies = 20 + 30 = 50
As the chosen candy is blue, the probability that is does not contain any nuts will be = (The number of blue candies without nuts)/(Total number of blue candies)
So, the probability = 30/50 = 0.6 *100% = 60%
Answer: 20%

When n = energy efficiency and Pin = energy input and Pout = energy output, how can you mathematically represent the correct relationship between the energy you put in something and the energy you get out?
A. n = P out * P in
B. n = P out / P in
C. n = P out - P in ...?
Answer:
[tex]n=\frac{P_{out}}{P_{in}}[/tex]
Step-by-step explanation:
We know that,
[tex]\text{Energy efficiency}=\frac{\text{Energy out put}}{\text{Energy in put}}[/tex]
If [tex]P_{in}[/tex] represents the energy input,
[tex]P_{out}[/tex] represents the energy output,
And, n represents energy efficiency,
Hence, the required formula would be,
[tex]n=\frac{P_{out}}{P_{in}}[/tex]

Answer:
She received $60 for each coin.Step-by-step explanation:
Mrs. Fletcher bought 5 coins for $32.Then, she sold them for $300.We need to divide to know how much Mrs. Fletcher received for the coins
[tex]\frac{\$300}{5}=\$60[/tex]
She received $60 for each coin.
Now, each coin had a cost of
[tex]\frac{\$32}{5}= \$6.40[/tex]

solve
3x + 2y + 5x - y
Answer: 8x+y
Step-by-step explanation:
you always combine your like terms, a trick is to put a line infront of your equation signs making it look like 3x/+2y/+5x/-y. This makes it easier to see if your terms are positive or negative. Now you have 5x+3x and 2y-y giving you 8x+y because its still positive.

Answer: option c.) 5
Step-by-step explanation: you must always follow PEMDAS
so first step would be parentheses but there are none so you move on to exponents. 4^0=1. so now you have 1+2x3-2.
Next step is multiplication. 2x3 is 6 so now you have 1+6-2.
Now we only have addition and subtraction so you move from left to right. 1+6=7
7-2=5
giving you option c. 5
A florist shop represents its first month’s sales with the equation y=168x+8, where x represents the number of days that the shop is open and y represents the sales in dollars. The owner of the shop would like to calculate the number of days it took to reach $3,200 in sales. Which would be used to solve the problem?
A-Substitute 3,200 for x.
B-Add 8 and 3,200.
C- Divide 3,192 by 168.
D-Isolate y in the equation.
Answer:
Option C is the answer.
Step-by-step explanation:
A florist sale is for it's first month is represented by the equation y = 168x + 8
Here y represents the sales in dollars and x represents number of days.
Now we have to calculate the number of days it took to reach $3200 in sales.
For this we will substitute $3200 in place of y and find the value of x by solving the equation.
3200 = 168x + 8
168x = 3200 - 8 = 3192
[tex]x=\frac{3192}{168}=19[/tex]
Therefore Option C. is the correct option.

Determine whether the following relation is a function.
{(3,7), (3,8), (3,-2), (3.4),(3,1)}
A) it is a function because the ordered pairs all have the same x-value.
B) it is not a function because there are multiple y-values paired with a single x-value.
C) it is a function because none of the ordered pairs have the same y-value.
D) it is not a function because none of the ordered pairs have the same y-value.
The relation is not a function it is not a function because there are multiple y-values paired with a single x-value. Option B.
Is the relation a function?A relation is a function only if every input is mapped into a single output.
Here we have the relation {(3,7), (3,8), (3,-2), (3.4),(3,1)}
Remember that the first number of each pair is the input, so we can see that all the inputs are the same one
So the input x = 3 is mapped into different outputs, thus, this is not a function.

The correct option is B) it is not a function because there are multiple y-values paired with a single x-value.
To determine if a relation is a function, one must check if each x-value is associated with exactly one y-value. In other words, for every x, there should be one and only one y. This is known as the vertical line test in the context of graphs.
Let's examine the given set of ordered pairs: {(3,7), (3,8), (3,-2), (3,4), (3,1)}.
We can see that the x-value of 3 is repeated with different y-values: 7, 8, -2, 4, and 1.
This means that the x-value of 3 is associated with multiple y-values, which violates the definition of a function.
Therefore, the relation is not a function because it fails to satisfy the condition that each x-value must correspond to exactly one y-value.
The presence of multiple y-values for a single x-value is the key indicator that the relation is not a function.
