Given graph will be a line parallel to [x] axis.

The general equation of a straight line is -

y = mx + c

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

Other possible equations of lines are -

For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of [x] for which [y] exists.

We have Mrs. Rao pays the same amount each month for Internet service.

Assume that he pays amount [k], each month. Then, we can write the equation representing the graph as -

Step-by-step explanation:

y = - 2² + 4

y = - 4 + 4

y = 0

(2,0)

The equation that has a real zero at x = 2 is y = -[tex]2^x[/tex] + 4.

Option A is the correct answer.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

The graph shows an x-intercept at x = 2, which means that the function has a real zero at x = 2.

Now,

We can check which of the given equations has this property by plugging in x = 2 and seeing if the corresponding y-value is zero.

For y = [tex]-2^x[/tex] + 4,

y = -2² + 4 = 0

This equation has a real zero at x = 2.

For y = 2^x,

y = 2² = 4,

This equation does not have a real zero at x = 2.

For y = log₂(x + 2) + 1,

y = log₂(2 + 2) + 1 = log₂4 + 1 = 3

This equation does not have a real zero at x = 2.

For y = log₂(-x + 2),

-x + 2 < 0, which means that x > 2.

This equation does not have a real zero at x = 2.

Therefore,

The equation that has a real zero at x = 2 is y = -[tex]2^x[/tex] + 4.

It is a supposition that it is true if two points are equally far apart from a third point and the three points are collinear.

If three or more points lie on a single straight line, they are said to be collinear. An axis is a term used to describe a line on which points are located, particularly if that line is connected to a triangle or other geometric shape. Since two points determine a line, two points are trivially collinear.

Collinear points are those that are situated along a  identical straight line.

The supposition is correct since all three points are located on the same line.

if the two points create a straight angle that includes the third point, then the conjecture is true.

If the two points do not create a straight angle with the third point, then the conjecture is false.

The combined ounces of meat and cheese used on each sandwich is 7 ounces and the combined ounces of meat on all sandwiches is 52 ounces and that of cheese on all sandwiches is 39 ounces.

We have the following information:

A sandwich hop serve 4 ounce of meat and 3 ounce of cheese on each sandwich. After making sandwiches for an hour the hop owner has used 91 combined ounce of meat and cheese.

Now, we know the combined ounces of meat and cheese for 1 sandwich will be given as follows:

Ounces of meat + ounces of cheese

4+3

7 ounces

Now, in an hour 91 ounces of combined cheese and meat are used.

So, we have the following expression:

Number of sandwiches made in 1 hour = Total ounces used/ounces used in 1 sandwich

Number of sandwiches = 91/7

Number of sandwiches = 13

Ounces of meat used in 13 sandwiches = 13*4

Ounces of meat used in 13 sandwiches = 52 ounces

Ounces of cheese used in 13 sandwiches = 13*3

Ounces of cheese used in 13 sandwiches = 39 ounces

Hence, the combined ounces of meat and cheese used on each sandwich is 7 ounces and the combined ounces of meat on all sandwiches is 52 ounces and that of cheese on all sandwiches is 39 ounces.

The rate of change in the attendance of students between 2018 and 2021 is 1.24.

The term "rate of change" (ROC) describes the rate at which something changes over time.

Thus, it is not the number of individual changes themselves but rather the acceleration or deceleration of changes (i.e., the rate).

The rate of change is a tool used in finance to comprehend price returns and spot trend momentum.

Divide the change in y-values by the change in x-values to determine the average rate of change.

Identifying changes in measurable values like average speed or average velocity calls for the knowledge of the average rate of change.

So, according to the given table:

The rates of change between 2018 and 2021 are:

Whenever a probability sample is drawn from a population, it is not enough to simply report the sample's descriptive statistics, for these measures contain a certain degree of error due to the sampling process.

Thus the answer is ‘ true’.

A population is any entire group that has at least one trait in common that is relevant to a given issue or experiment in statistics.

A probability sample is one that is drawn using a method of random selection that is compatible with the known odds for each member of the population to be selected, and that takes these probabilities into account when generating estimates from the sample.

If the chosen sample does not accurately reflect the total population of data, there has been a sampling error, which is a statistical error resulting from sampling.

To make the quadratic polynomial x² + 18x into a perfect square, we add 81 to it.

A quadratic polynomial is a polynomial in which the highest power of the unknown is 2.

A perfect square is a number suvh that it is equal to another number multiplied by itself

Since we have the quadratic polynomial x² + 18x, and we wnat to convert it to a perfect square.

To be a perfect square, we want it in the form (x + a)² = x² + 2ax + a²  (1)

Compring the quadratic polynomial with equation (1), we have that

2a = 18

a = 18/2

a = 9

⇒ a² = 9² = 81

So, substituting a = 9 into equation (1), we have

(x + a)² = x² + 2ax + a²

(x + 9)² = x² + 2(9)x + 9²

= x² + 18x + 81

Answer:

  24.98 units

Step-by-step explanation:

You want the perimeter of triangle ABC with vertices A(-5, 4), B(1, -2), and C(3,6).

The distance between two vertices can be found using the formula ...

  d = √((x2 -x1)² +(y2 -y1)²)

The  distance between A and B is ...

  d = √((1 -(-5))² +(-2 -4)²) = √(6² +(-6)²) = 6√2 ≈ 8.485

The attached spreadsheet performs the same calculation on all the pairs of points. (The distance from each point to the one below it is listed.)

The perimeter of the triangle is the sum of the segment lengths. That is also shown in the spreadsheet.

  P = AB +BC +CA

  P = 8.485 +8.246 +8.246 ≈ 24.98

The perimeter of triangle ABC is about 24.98 units.

When calculations are repetitive, we like to let a spreadsheet do them.

Mrs. Jones will make 55 wax warmers when she produces 77 candles.

The given table shows the ratio of the number of candles to the number of wax warmers she makes.

Let's assume that "x" wax warmers will she make when she makes 77 candles

According to the given question, we can write the ratio would be as:

7 Candles : 5 Wax Warmers = 77 Candles : x Wax Warmers

⇒ 7/5 = 77/x

⇒ 7x = (77)(5)

Divided by 7 on both sides of the above equation,

⇒ x = (77)(5)/7

⇒ x = 11 × 5

Apply the multiplication operation, we get

⇒ x = 55

Answer: He will work for 19 days.

Step-by-step explanation:

If Nicholas has 234 dollars and the computer he wants to put is 899 dollars, you have to subtract to see how much he has to take the loan from his parents in order to buy the computer.

899 - 234 = 665

He took a loan of 665 dollars from his parents

To figure out how many days he needs to work to pay that amount, you divide the amount he earns each day with the amount of loan he took.

So 665 divided by 35 = 19

He has to work 19 days to pay off the 665 dollar loan he took from his parents.

We can check this answer by multiplying 35 x 19 , which equals to 665.
