what is the function of delta sign in maths
Final answer:
The delta sign (Δ) in mathematics indicates a change in a certain quantity, calculated by subtracting the initial value from the final value, commonly used for indicating displacement in physics.
Explanation:
The delta sign (uppercase Greek letter delta, Δ) is commonly used in mathematics to denote a change in a certain quantity. When we say Δx, it signifies the 'change in x' or the difference between the final and initial values of 'x'. This is typically calculated by subtracting the initial value xo from the final value xf. For instance, if we're calculating displacement, which is a change in position, we subtract the starting position xo from the ending position xf to get Δx. The SI unit for displacement is the meter, but other units such as kilometers may also be used, requiring conversion to meters for consistency in calculations.

Ben is showing his work in simplifying (3.9 − 9.4) − 0.6 + 6.1. Identify any error in his work or reasoning.
Step 1: (3.9 − 9.4) − 0.6 + 6.1
Step 2: 3.9 + (−9.4 − 0.6) + 6.1 (associative property) Step 3: 3.9 − 10 + 6.1
Step 4: 3.9 + 6.1 − 10 (identity property)
Step 5: 10 − 10 = 0
A. He wrote identity instead of commutative in step 4.
B. He wrote associative instead of commutative in step 2.
C. He wrote identity instead of distributive in step 4.
D. He wrote associative instead of distributive in step 2.
Answer:
A.He wrote identity property instead of commutative in step 4.
Step-by-step explanation:
We are given that
Ben is showing his work in simplifying (3.9-9.4)-0.6+6.1
We have to identify error made by Ben in his work
Step 1. (3.9-9.4)-0.6+6.1
Step 2.3.9+(-9.4-0.6)+6.1
Reason: Using associative property of addition
[tex](a+b)+c=a+(b+c)[/tex]
Step 3.3.9-10+6.1
Step 4.3.9+6.1-10
Reason: Using commutative property of addition
[tex]a+b=b+a[/tex]
Step 5.10-10=0
Therefore, he makes an error in step 4.he wrote identity property instead of commutative property of addition.
Hence, option A is true.
Answer: A.He wrote identity property instead of commutative in step 4.

Point A is located at negative 5 over 8 and point B is located at negative 2 over 8 . What is the distance between points A and B? (1 point)
negative 5 over 8 minus negative 2 over 8 = negative 3 over 8 ; therefore, the distance from A to B is absolute value of negative 3 over 8 equals 3 over 8 units
negative 5 over 8 minus negative 2 over 8 = negative 3 over 8 ; therefore, the distance from A to B is absolute value of negative 3 over 8 equals negative 3 over 8 units
negative 5 over 8 plus negative 2 over 8 = negative 7 over 8 ; therefore, the distance from A to B is absolute value of negative 7 over 8 equals 7 over 8 units
negative 5 over 8 plus negative 2 over 8 = negative 7 over 8 ; therefore, the distance from A to B is absolute value of negative 7 over 8 equals negative 7 over 8 units

Write 1.04 x 10^2 in standard form
Answer:
The required standard form is 104.
Step-by-step explanation:
Consider the provided number.
you can convert the scientific notation into long hand notation as shown:
If the exponent of 10 is a positive number then you need to move the decimal point right as much as the exponent value.
If the exponent of 10 is a negative number then you need to move the decimal point left as much as the exponent value.
Now consider the provided number.
[tex]1.04 \times 10^2[/tex]
Here the power of 10 is positive, so move the decimal point right as shown.
[tex]104[/tex]
Hence, the required standard form is 104.
Hailey paid $13 dollars for 1 3/7 kg of sliced salami.
Answer:
$9.1 per kg of sliced salami.
Step-by-step explanation:
We are supposed to find unit rate for the given scenario.
Hailey paid $13 dollars for 1 3/7 kg of sliced salami.
To find unit rate, we will divide total price by total weight.
[tex]\text{Unit rate}=\$13\div 1\frac{3}{7}\text{ kg}[/tex]
Convert mixed fraction to improper fraction:
[tex]\text{Unit rate}=\$13\div \frac{10}{7}\text{ kg}[/tex]
Convert to division problem by flipping the fraction as:
[tex]\text{Unit rate}=\$13\times\frac{7}{10}\text{ kg}[/tex]
[tex]\text{Unit rate}=\frac{\$13\times7}{10\text{ kg}}[/tex]
[tex]\text{Unit rate}=\frac{\$91}{10\text{ kg}}[/tex]
[tex]\text{Unit rate}=\frac{\$9.1}{\text{ kg}}[/tex]
Therefore, unit rate is $9.1 per kg of sliced salami.

Who sets the price in a monopolistic competition?
The producer sets the price in a monopolistic competition.
Further Explanation:
Monopolistic Competition:
Monopolistic competition is a type of competition where a large number of seller offer similar but not perfect substitute products. Each producer offers a different product at different price based on the exclusive characteristic of the product. Major characteristics of monopolistic competition are as follows:
• Different product
• Large number of producers
• Freedom of entry and exit
• Market power (Producer)
Setting the price in monopolistic competition:
In monopolistic competition, the producer has the power to pricing power. In this type of competition, the producers offer different products as compared to other competitors and charge the customer according to their product differentiation. Therefore, they have the power to set and change the price on the basis of their offered product.
Thus, the producer sets the price in a monopolistic competition.

In monopolistic competition,
The price is typically set by individual firms or businesses rather than a centralized authority.
We have,
Each firm has some degree of market power, allowing them to differentiate their products or services from their competitors.
Firms in monopolistic competition have the freedom to set their prices based on factors such as production costs, demand for their product, market conditions, and desired profitability.
They aim to find the price that maximizes their own profits or achieves their specific business objectives.
However, it's important to note that in monopolistic competition, there is competition among firms, albeit with differentiated products.
As a result, firms must also consider the prices set by their competitors to remain competitive and attract customers.
Thus,
In monopolistic competition, the price-setting decision lies with the individual firms, balancing their own considerations and market dynamics to determine the optimal price for their product or service.
