a relation contains the points (-5,-10) (-2,-4) (-1,-2) (4,8) (5,10) is this a function?

Answers

Answer:

This is a function and there is no value of x for which we will get two or more different values of y.

Step-by-step explanation:

A relation contains the points (-5,-10), (-2,-4), (-1,-2), (4,8), and (5,10).

So, if we want to model the equation that includes those points then we will get the equation of a straight line passing through the origin {Since the rate of change of y with respect to x is uniform.

The equation is y = 2x

Now, this is a function and there is no value of x for which we will get two or more different values of y. (Answer)

Suppose that y varies directly with x
and y = 10 when x = 20. What is y
when x = 15?
It’s a fraction

Answers

Answer:

15/2

Step-by-step explanation:

y varies directly as x can be written as:

y & x

y = Kx

K = y/x

But from the question, we were told that:

y = 10

X = 20

K = y/x

K = 10/20

K = 1/2

The formula for the expression is:

y = Kx

y = 1/2 x

Now let us solve for y, when:

x = 15

y = 1/2 x

y = 1/2 x 15

y = 15/2

Final answer:

To find the value of y when x = 15, we first determined the constant of proportionality (k) using the given y and x values, which was found to be 0.5. We then plugged x = 15 into the direct variation formula y = kx, resulting in y = 7.5.

Explanation:

If y varies directly with x and y = 10 when x = 20, then we can write this direct variation as y = kx, where k is the constant of proportionality. To find k, we substitute the known values of x and y and solve for k:
10 = k × 20
k = 10 / 20
k = 0.5
With k found, we can now determine what y is when x = 15:

y = k × x
y = 0.5 × 15
y = 7.5

a book store cost $80 a day to keep open, and it spends $15 for each book that it sells. if each book sells for $23, what is the break-even point for this booksotre?

Answers

The break even point for this book store is 10

Solution:

Given that, book store cost $80 a day to keep open, and it spends $15 for each book that it sells

Cost to open the book store = $ 80

The formula for solving the break even point (BEP) is:

[tex]BEP = \frac{\text{Fixed cost}}{\text{Selling price - variable cost}}[/tex]

Fixed Cost is the cost that remains constant whether the services provided or products sold increases or decreases

Variable Cost is the cost that varies or differs in proportion to the products or services produced, whether they increased or decreased

In this problem,

Fixed cost = $ 80

Selling price = $ 23

Variable cost = $ 15

Therefore,

[tex]BEP = \frac{80}{23-15}\\\\BEP = \frac{80}{8}\\\\BEP = 10[/tex]

Thus break even point for this book store is 10

In order for the bookstore to continue its business, it should sell at least 10 books to meet its $80 cost

Step-by-step explanation:

the arlington drama club is selling tickets to an upcoming play. They can sell at most 250 tickets. The adult tickets for $15 each and student tickets costs $5 each. They would like to raise at least $2000. It x represents the number of adult tickets and y represents the number of student tickets.

Answers

Number of adult tickets = 75

Number of student tickets = 175

Solution:

Let x represents the number of adult tickets and

y represents the number of student tickets.

Total number of tickets sold = 250

x + y = 250 – – – – (1)

Cost of adult ticket = $15

Cost of student ticket = $5

Total cost of collection = $2000

15x + 5y = 2000 – – – – (2)

Multiply equation (1) by 5

⇒ (1) × 5  5x + 5y = 1250 – – – – (3)

Subtract equation (3) from equation (2), we get

15x + 5y – 5x – 5y = 2000 – 1250

⇒ 10x = 750

x = 75

Substitute x = 75 in equation (1), we get

⇒ 75 + y = 250

⇒ y = 250 – 75

y = 175

Number of adult tickets = 75

Number of student tickets = 175

Test corner points for maximum revenue. The optimal solution is 250 adult tickets and 0 student tickets, yielding $3750.

To solve this problem, let's set up the equations based on the given information:

1. The total number of tickets sold cannot exceed 250:

[tex]\[ x + y \leq 250 \][/tex]

2. The total revenue must be at least $2000:

[tex]\[ 15x + 5y \geq 2000 \][/tex]

Now, let's solve this system of inequalities step by step:

Step 1: Graph the constraints:

Let's graph the lines corresponding to the equations:

x + y = 250 and  15x + 5y = 2000

Step 2: Find the feasible region:

The feasible region is the area that satisfies all the given constraints. In this case, it will be the region below or on the lines ( x + y = 250 ) and ( 15x + 5y = 2000 ), and within the boundaries of the axes.

Step 3: Identify the corner points:

The corner points of the feasible region are the points where the lines intersect or touch the boundary lines.

Step 4: Test the corner points:

Substitute the coordinates of each corner point into the objective function (the total revenue) to find which one yields the maximum revenue.

Let's start with the calculations:

1. **Graph the constraints:**

We'll need to find the intercepts of each line and draw them on the graph.

For ( x + y = 250 ):

When ( x = 0 ), ( y = 250 )

When ( y = 0 ), ( x = 250 )

For ( 15x + 5y = 2000 ):

When ( x = 0 ), ( y = 400 )

When ( y = 0 ),[tex]x = \frac{2000}{15} = \frac{400}{3} \)[/tex]

Now, let's plot these points and draw the lines.

2. **Find the feasible region:**

Shade the region below or on the lines ( x + y = 250 ) and ( 15x + 5y = 2000 ), and within the boundaries of the axes.

3. **Identify the corner points:**

The corner points of the feasible region are the points where the lines intersect or touch the boundary lines.

4. **Test the corner points:**

Substitute the coordinates of each corner point into the objective function ( R = 15x + 5y ) to find which one yields the maximum revenue.

Let's calculate the corner points:

Corner Point 1: (0, 0)

[ R = 15(0) + 5(0) = 0 ]

Corner Point 2: (250, 0)

[ R = 15(250) + 5(0) = 3750 ]

Corner Point 3: (0, 400)

[ R = 15(0) + 5(400) = 2000 ]

Now, let's compare the revenues:

- Corner Point 1: $0

- Corner Point 2: $3750

- Corner Point 3: $2000

The maximum revenue is $3750, which occurs at the corner point (250, 0).

Therefore, to maximize revenue while satisfying the given constraints, the Arlington Drama Club should sell 250 adult tickets and 0 student tickets.

A college student borrows $1500 for 9 months to pay for a semester of school . if the interest is $92.81 find the monthly payment

Answers

The monthly payment for the loan of $1500 with $92.81 interest over 9 months is $176.98.

To calculate the monthly payment for a $1500 loan with $92.81 in interest over 9 months, we must first find the total amount to be paid back, which includes both the principal and the interest. The total repayment amount will be $1500 (the original loan) plus $92.81 (the interest), making the total amount $1592.81.

We can then divide this total amount by the number of months the loan will be held to find the monthly payment:

Monthly Payment = Total Repayment Amount ÷ Total Months

Monthly Payment = $1592.81 ÷ 9

Monthly Payment = $176.98

Therefore, the student needs to pay $176.98 every month to pay off the loan in 9 months.

If you get a loan of $1,500 at an interest rate of 10% and the monthly payment is $131.85, what is the new principal after the first payment?​ (please explain how you got it)

Answers

Answer:

The new principal after the first payment is $ 1,380.65

Step-by-step explanation:

1. We calculate the amount of interest to pay in the first payment, this way:

Interest = Amount of loan * (interest rate/months in a year)

Replacing with the real values we know:

Interest = 1,500 * (0.1/12)

Interest = 1500 * 0.0083 = $ 12.50

2. Now we subtract the Interest from the monthly payment, as follows:

Payment to principal = 131.85 - 12.50

Payment to principal = $ 119.35

3. Finally we subtract that 1st payment to principal from the initial principal to get the new principal, this way:

New Principal = 1,500 - 119.35

New Principal = $ 1,380.65

The new principal after the first payment is $ 1,380.65

A circle circumference is approximately 76 cm estimate the radius diameter and area of the circle

Answers

Answer: r = 12.1cm, d = 24.2cm, Area = 460.0cm²

Step-by-step explanation:

From the formula,

Circumference of a circle = πd or 2πr.

To find the radius, we have to equate 76 cm to πd or 2πr and make r or d the subject of the formula. Now

76 = 2πr, don't forget that

π = 22/7 or 3.142

Now make r the subject of the formula

r = 76/2π

= 76/2 x 3.142

= 76/6.284

= 12.1 cm

d = 2r

= 2 x 12.1

= 24.2cm.

Area of the circle is πr²

= 3.142 x (12.1)²

= 3.142 x 146.41

= 460.0 cm²

If the 3 longest bulletin boards were side by side, what would their total length be?

Answers

The total length of the three longest bulletin boards when placed side by side would be 180 inches.

To calculate the total length of the three longest bulletin boards when placed side by side, we first need to determine the average length of a bulletin board and then multiply it by three.

The length of bulletin boards can vary widely depending on their purpose, but let's assume a standard size commonly found in schools or offices.

A typical bulletin board might measure around 4 feet (48 inches) in length.

However, some bulletin boards can be longer, reaching up to 6 or 8 feet.

Let's take a conservative estimate of 5 feet (60 inches) for our calculations.

So, if we have three bulletin boards each measuring 5 feet (60 inches) in length, the total length when placed side by side would be:

Total length = Length of one bulletin board × Number of bulletin boards

Total length = 60 inches × 3

Total length = 180 inches

Therefore, the total length of the three longest bulletin boards when placed side by side would be 180 inches.

What is an equivalent fractions to 5/12

Answers

Answer:

exact form is 5/12

decimal form is 0.416666

Step-by-step explanation:

Final answer:

Equivalent fractions are fractions that have the same value or proportion. To find an equivalent fraction to a given fraction, you multiply or divide both the numerator and the denominator by the same number. Therefore, 10/24 and 15/36 are equivalent fractions to 5/12.

Explanation:

To find an equivalent fraction to 5/12, you simply multiply or divide both the numerator (the top number) and the denominator (the bottom number) by the same non-zero number. An equivalent fraction will have a different numerator and denominator, but it will represent the same value or proportion. For example, if we multiply both the numerator and the denominator of 5/12 by 2, we get 10/24. Therefore, 10/24 is an equivalent fraction to 5/12.

Similarly, if we multiply 5 (the numerator) and 12 (the denominator) by 3, we get the equivalent fraction 15/36.

So, 5/12 = 10/24 = 15/36 in terms of value or proportion.

Final answer:

Tom read a total of 11/12 of the two books combined by reading 1/2 of the first book and 5/12 of the second book, after finding a common denominator to add the fractions.

Explanation:

To calculate the total fraction of the two books that Tom has read, we need to add the fractions of each book he has read together. Tom read 1/2 of the first book and 5/12 of the second book.

To add these fractions, they need to have a common denominator. The lowest common denominator between 2 and 12 is 12.

Therefore, we convert 1/2 into 6/12 so that both fractions have the same denominator.

Now, the fractions to be added are 6/12 (from the first book) and 5/12 (from the second book).

Adding these fractions, we get:

6/12 + 5/12 = 11/12

So, Tom has read a total of 11/12 of the two books combined. This method of finding a common denominator and then adding the numerators is an effective strategy to add fractions with different denominators, providing a clear, step-by-step approach to solving such problems in mathematics.

If 1000 adults attended the fair right and solve the Larry Quetion to find the number of children that attended Consider a tank used in certain hydrodynamic experiments. After one experiment the tank contains 200 L of a dye solution with a concentration of 1 g/L. To prepare for the next experiment, the tank is to be rinsed with fresh water owing in at a rate of 2 L/min, the well-stirred solution owing out at the same rate. a. Find the time that will elapse before the concentration of dye in the tank reaches 1% of its original value. Bottom trawling is a type of deep-sea fishing that involves dragging a large net along the bottom of the ocean, and it results in catching and killing many unintended species, some of which are endangered. Environmental advocates, concerned for these endangered marine species, have recommended that commercial fishers use a new set of nets, each designed specifically for the size and shape and pheromones (chemical attractors) of an individual marine species targeted by the commercial fishers. Environmentalists hope use of these new nets will protect the endangered marine species without interrupting commercial deep-sea fishing.Which of the following, if true, most strongly supports the claim that use of the new nets will have the intended effects?(A) The pheromones that would most attract the food species sought by commercial fishers indicate the presence of a dangerous threat to most of the endangered marine species.(B) Some endangered marine species are particularly large, as large any species targeted by commercial deep-sea fishing.(C) Most of the newly design nets are not significantly more expensive than a typical bottom trawling system.(D) Catching unintended, endangered species adds nothing to the profits of a commercial deep-sea fishing company.(E) Freshwater fishers often increase the odds of catching a desired fish, and avoid catching unintended species, by the specific design of the fishing hook. In a hypothetical situation, a certain species of flea feeds only on pronghorn antelopes. In thewestern United States, pronghorns and cattle often associate with one another in the same openrangeland. Some of these fleas develop a strong preference for cattle blood and mate only withother fleas that prefer cattle blood. The host mammal can be considered as the fleashabitat. If thissituation persists, and new species evolve, this would be an example of _____.A) allopatric speciation and gametic isolationB) sympatric speciation and temporal isolationC) allopatric speciation and habitat isolationD) sympatric speciation and habitat isolation When Kirk and Elisa formed their general partnership, Kirk contributed 90 percent of the capital, and Elisa contributed 10 percent.
