Parallel lines were coplanar endless straight lines in geometry that never intersect. Therefore, all the options are correct.
What are parallel lines?Parallel lines were coplanar endless straight lines in geometry that never intersect. Within a single three-dimensional space, parallel planes are any planes that never cross. Curves with a predetermined minimum distance between them and no contact or intersection are said to be parallel.
Euclid's parallel postulate deals with parallel lines. Euclidean geometry is just a particular example of this sort of geometry, and parallelism is essentially a feature of affine geometries. Lines can have similar characteristics known as parallelism in various other geometries, including such hyperbolic geometry.
∠2≅∠8 ( alternate interior angle)
∠1≅∠8 (vertical angle)

Dairy Queen has been analyzing their sales and profit records. They came up
with the following equations:
A. The function below shows Profit, P, as a function of the cost of a blizzard x.
P(x) - 65(x - 4) + 1000
=
1. At what prices would Dairy Queen earn zero profit?
2. How should Dairy Queen price their blizzards to maximize profits?
3. What is their estimated maximum profit?
4. Sketch a graph and make sure to label the x and y axis.
The function P(x) = -65(x - 4)² + 1000 of Dairy queen is an illustration of quadratic functions
Dairy queen should price their blizzards at $4, and the estimated maximum profit is $1000
The price that gives zero profitThe function is given as:
P(x) = -65(x - 4)² + 1000
At zero profit, P(x) = 0
So, we have:
-65(x - 4)² + 1000 = 0
From the graph of the function (see attachment), we have:
x = 0.078 and x = 7.922
Hence, the prices that give zero profit are 0.078 and 7.922
How to maximize profits?To maximize profit, Dairy Queen should their blizzards at a price that yields maximum profit
The estimated maximum profitWe have:
P(x) = -65(x - 4)² + 1000
A quadratic function is represented as:
P(x) = a(x - h)² + k
Where:
Vertex = (h,k)
So, we have:
h = 4 and k = 1000
Hence, Dairy queen should price their blizzards at $4, and the estimated maximum profit is $1000

Write an equation using x when the sum of a number and 8 is multiplied by 3and the answer is 6
Answer:
3(x + 8) = 6
Step-by-step explanation:
let the number be x then the sum of x and 8 is x + 8 and multiplied by 3 is
3(x + 8) = 6 ( divide both sides by 3 )
x + 8 = 2 ( subtract 8 from both sides )
x = - 6

Step-by-step explanation:
The only relevant information is each side of the pentagonal pyramid is 9 years and so the perimeter of the base is 45 since 9 x 5 = 45 yards.

Answer:
137 m²
Formula's:
area of rectangle: length + widtharea of triangle: 1/2 * base * heightExplanation:
⇒ area of rec + area of rec + area of rec + area of triangle
⇒ 2 * 4 + 7 * 6 + 8 * 9 + 1/2 * 6 * 5
⇒ 8 + 42 + 72 + 15
⇒ 137 m²
Answer:
137 m²
Step-by-step explanation:
Divide the figure into a triangle and 3 rectangles (see attached diagram)
Formulae
Area of a triangle = 1/2 x base x heightArea of a rectangle = width x lengthTriangle 1
⇒ area = 1/2 x (8 + 7 + 2 - 4 - 7) x 5
= 1/2 x 6 x 5
= 15 m²
Rectangle 2
⇒ area = 4 x (2 + 7 + 8)
= 4 x 17
= 68 m²
Rectangle 3
⇒ area = 2 x (7 + 8)
= 2 x 15
= 30 m²
Rectangle 4
⇒ area = 3 x 8
= 24 m²
Total area
⇒ Total area = triangle 1 + rectangle 2 + rectangle 3 + rectangle 4
= 15 + 68 + 30 + 24
= 137 m²
only question 6 and 7 please answer fast I need it now ty
Answer:
6. $62.74 7.$331
Step-by-step explanation:
6. The original cost= $119.5
After 30% of discount = (70/100)× 119.5
= $83.65
After 25% discount = (75/100)× 83.65
= $62.74
7. Original cost= 679
Price after 35% discount = (65/100)×679=$441.35
Price after 25% discount = (75/100)× 441.35
=$331
So the final price will be = $331

Write the explicit rule in simplified form for the sequence.
an

Considering the recursive rule, the explicit rule for the arithmetic sequence is given by:
[tex]a_n = 14 + 4(n - 1)[/tex]
What is an arithmetic sequence?In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.
The nth term of an arithmetic sequence is given by:
[tex]a_n = a_1 + (n - 1)d[/tex]
In which [tex]a_1[/tex] is the first term.
From the recursive sequence, we have that the first term is [tex]a_1 = 14[/tex], while each term is the previous added to four, hence the common difference is d = 4. Thus, the explicit formula is given by:
[tex]a_n = 14 + 4(n - 1)[/tex]

Answer:
1/18
Step-by-step explanation:
Use the counting principle to find the total number of different sandwiches you can make.
2 breads
3 meats
3 condiments
Total number of different sandwiches = 2 × 3 × 3 = 18
There are 18 possible sandwiches.
You are intereseted in 1 specific sandwich out of the 18.
p(wheat bread, ham, mustard) = 1/18
1/18 is the probability that you will make a sandwich with wheat bread, ham, and mustard.
What is a number?A number is an arithmetic value used to represent quantity.
We can use the counting principle to find the total number of ways to make different sandwiches.
2 breads, 3 meats, and 3 condiments.
Total number of sandwich varieties = 2* 3* 3 = 18
There are 18 possible sandwiches.
You're only interested in one of the 18 sandwich varieties.
i.e. p(wheat bread, ham, mustard) = 1/18
Hence, the probability that you will make a sandwich with wheat bread, ham, and mustard is 1/18.
