Identify if there is a function in each given relation. 1. {(cat, 1), (dog, 5), (cat, 6), (chicken, 9)) 2. ((a,10), (b, 11), (-a, 12), (c,13)},

Answers

The relation {(cat, 1), (dog, 5), (cat, 6), (chicken, 9)} is not a function, because there are two ordered pairs with the same first element, "cat" - (cat, 1) and (cat, 6). In a function, each input (first element) must correspond to only one output (second element).

The relation { (a,10), (b, 11), (-a, 12), (c,13)} is also not a function, because the input "-a" and "a" have different outputs (12 and 10, respectively). In a function, each input must correspond to only one output.

A function is a relation between a set of inputs and a set of possible outputs with the property that each input is associated with exactly one output. In other words, for each input, there is only one output.

The concept of functions is important in many areas of mathematics and its applications, such as physics, engineering, and computer science. Functions can be represented using various mathematical notations, such as tables, graphs, or algebraic formulas.

Which of the following represents, "The difference between ten and a number is the sum of eight and a number"? 10 - N(8 + N)
8 - N = 10 + N
10 - N = 8 + N

Answers

Answer:

The sentence represents 10 - N = 8 + N

C is correct.

Step-by-step explanation:

Given: "The difference between ten and a number is the sum of eight and a number"

We are given an statement and need to write in expression.

Let the number be N

First we take half sentence.

"The difference between ten and a number"

Expression 1 ⇒ 10 - N

Next Half sentence.

"The sum of eight and a number"

Expression 2 ⇒ 8 + N

Expression 1 is equal to expression 2

Therefore, The equation is

10 - N = 8 + N

Hence, The sentence represents 10 - N = 8 + N

The difference between ten and a number is the sum of eight and a number is represented by:

10 - N = 8 + N

The cost for a company to manufacture x bracelets can be represented by the function c(x). complete the sentence belowIf c(256)=1536, then the cost of the company is $ _______ to manufacture ____________ bracelets.
Answer 1: _______
Choices: 1536, 256
Answer 2
Choices: 1536, 256

Answers

Answer:

$ 1536, 256 bracelets

Step-by-step explanation:

Here, c(x) represents the cost for a company to manufacture x bracelets.

Given that:

c(256) = 1536

⇒ $\text{Number of bracelets manufacture} = 256$

and

$\text{Cost of the company} = \$1536$

Therefore, the cost of the company is $ _1536______ to manufacture ____256________ bracelets

c(x) ⇒ cost for a company
x = number of bracelets manufactured

c(256) = 1536

The cost of the company is $1,536 to manufacture 256 bracelets.

Unit cost may be derived by:

cost per bracelet = 1536/256 = 6

c(x) = 6x
c(256) = 6(256)
c(256) = 1536

Dan pays £714.73 a year in his car insurance. The insurance company reduces the price by 4.1%. How much does the insurance cost now? Give your answer to 2 DP.

Answers

Answer:

£682.57

Step-by-step explanation:

Dan pays £714.73 a year in his car insurance.

The price was reduced by 4.1%

To find the new cost of the insurance, we simply need to find 4.15% of £714.73 and then subtract that from the initial price of the insurance (£714.73)

4.5% of 714.73 is:

$(4.5)/(100) * 714.73$ = £32.16

Then, the cost of the insurance now is:

£714.73 - £32.16 = £682.57

The insurance now costs £682.57

Final answer:

To calculate the new price of the insurance, we first calculate the discount, which is 4.1% of the original price (£714.73). Then, subtract this discount from the original price. Understanding percentage reduction is fundamental in calculating such discounts.

Explanation:

To calculate the new cost of car insurance, we will subtract the 4.1% reduction from the original price of £714.73. The percentage reduction can be calculated using the formula: Discount = Original Price x (Percentage / 100).

In our case, the discount is given by: Discount = £714.73 x (4.1 / 100).

Then, we subtract this discount from the original price to obtain the new price of insurance: New Price = Original Price - Discount.

Insurance premiums are a significant factor in personal finance, but factors like discounts can make them more affordable. It is crucial to understand the concept of percentage reductions to comprehend how discounts significantly affect the final cost for services such as insurance.
