The product of sum and difference of two binomial like (x+y) and (x-y) isof two squares. (FERFENCEID)

Answers

The product of sum and difference of two binomial like (x+y) and (x-y) is x² - y²

The first number = x

The second number = y

The sum of the two numbers = x + y

The difference of the two numbers = x - y

The product of the sum and the difference = (x+y)(x -y)

Note that the product of the sum and the difference = (x + y)(x - y)

This can be expanded by distributivity as shown below:

(x + y)(x - y) = x² + xy - xy - y²

(x + y)(x - y) = x² - y²

This is the difference of two squares.

Therefore, the product of sum and difference of two binomial like (x+y) and (x-y) is x² - y²

Which best describes the graph of the function f(x) = 4(1.5)x?

Answers

In the question "Which best describes the graph of the function f(x) = 4(1.5)^x?" The correct answer is "The graph passes through the point (0, 4), and for each increase of 1 in the x-values, the y-values increase by a factor of 1.5." (option B) Because when x = 0, f(0) = 4(1.5)^0 = 4(1) = 4. Thus the graph passes through (0, 4). Also for every increase of 1 in the x-values, the y-values increase by a factor of 1.5 i.e. f(0) = 4(1.5)^0 f(1) = 4(1.5)^1 f(x) = 4(1.5)^2 etc

A fierce guard dog is tethered by a 15 m chain to a post that is 6 m from a straight path. For what distance along the path is a trespasser in danger from the dog?

Answers

The distance from the road where an intruder would be in danger is 27.48 m.

To know how far from the road an intruder is in danger due to the dog, it is necessary to carry out the following procedure:

Establish the range of the dog with a circle of 15 meters in radius around the post on which he is tied.

In this part it can be inferred that a part of the path is in the range of the dog between points B and D (In this area the intruder would be in danger)

From this we know the following data:

Length AB = 15mLength AD = 15mLength AC = 6m

To know the length of points BC and CD we must perform a calculation using the formula of the Pythagorean theorem.

BC = [tex]\sqrt{15^{2} - 6^{2} }[/tex]BC = [tex]\sqrt{225-36}[/tex]BC = [tex]\sqrt{189}[/tex]BC = 13,74 m

Later we use the same procedure to find the length CD.

CD = [tex]\sqrt{15^{2} - 6^{2} }[/tex]CD = [tex]\sqrt{225-36}[/tex]CD = [tex]\sqrt{189}[/tex]CD = 13,74 m

Finally, we add both lengths (BC + CD) to know the distance in which an intruder is in danger within the dog's range.

BC + CD = BD = 27,48 m

A worker has job offers from two companies. The information below summarizes the job offer from each company.Company A:Starting salary of $31,000Raise of $3000 each yearCompany B:Starting salary of $38,000Raise of $2000 each yearPart A: Write an equation in terms of n years that can be used to determine the number of years when the salaries would be the same for both companies.Part B: Use the equation you wrote in part A to determine the number of years it would take for the salaries to be the same for both companies. Use mathematics to support your answer.

Answers

Using linear functions, we have that:

For Company A: [tex]S_A(n) = 31000 + 3000n[/tex]

For Company B: [tex]S_B(n) = 38000 + 2000n[/tex]

B. The salaries will be the same after 7 years.

A linear function is given by:

[tex]y = mx + b[/tex]

In which:

m is the slope, which is the rate of change.b is the y-intercept, which is the initial value.

Item a:

For Company A, the salary starts at $31,000, with a raise of $3,000 each year. Thus, [tex]b = 31000, m = 3000[/tex], and the salary after n years is given by:

[tex]S_A(n) = 31000 + 3000n[/tex]

For Company B, the salary starts at $38,000, with a raise of $2,000 each year. Thus, [tex]b = 38000, m = 2000[/tex], and the salary after n years is given by:

[tex]S_B(n) = 38000 + 2000n[/tex]

Item b:

They will be the same after n years, for which:

[tex]S_A(n) = S_B(n)[/tex]

Then

[tex]31000 + 3000n = 38000 + 2000n[/tex]

[tex]1000n = 7000[/tex]

[tex]n = \frac{7000}{1000}[/tex]

[tex]n = 7[/tex]

The salaries will be the same after 7 years.

Airfare from Atlanta, GA to Nashville,TN was decreased from $250 to $180. By what percentage did the cost of the airfare change?

Answers

Answer:A decrease of 28%

Step-by-step explanation: the question says decreased so you can mark out A and B then 250-180 is 70, 70% of 250 is 28%

The percentage is the indicating hundredth thus the percentage change from $250 to $180 is 28%.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

As per the given question,

Initial price of Airfare = $250

Final price of Airfare = $180

The percentage = change/initial × 100

Percentage decrease = (250 - 180)/250 × 100

⇒ 0.28 × 100 = 28%

Hence "The percentage is the indicating hundredth thus the percentage change from $250 to $180 is 28%".

Your friend calculates the distance between points Q(1,5) and R(3,8), as shown below. What is his error?

Answers

The distance between two points is the number of units between them.

The distance between Q and R is 3.61 units

It is impossible to determine your friend's error, because the steps are not given in the question. So, I will calculate the distance between Q and R, instead.

The distance (d) between two points is:

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

So, the distance QR is:

[tex]QR = \sqrt{(1 - 3)^2 + (5 - 8)^2}[/tex]

[tex]QR = \sqrt{(- 2)^2 + (- 3)^2}[/tex]

Evaluate exponents

[tex]QR = \sqrt{4 +9}[/tex]

[tex]QR = \sqrt{13}[/tex]

Take square root of 13

[tex]QR = 3.61[/tex]

Hence, the distance between Q and R is 3.61 units

Answer:

Median. Explanation to each part below.

Step-by-step explanation:

a) Starting with calculating the mean, which is all the values added divided by the number of values (in this case he has 6 scores total).

[tex]mean/average=\frac{81+87+93+89+61+81}{6} =\frac{492}{6} = 82[/tex]

b) To find the median, arrange all the test scores in increasing order and find the middle/median value. We have 6 scores, so we will have 2 middle scores. If we had 7 scores, we would find only 1 score in the middle which would be the median. We will have to find the average of the two scores.

[tex]61,81,81,87,89,93[/tex]

The middle values will be 81 and 87 so find the average of those 2 scores.

[tex]Median: \frac{81+87}{2} =\frac{168}{2} =84[/tex]

c) The mode is the score which occurs the most. In this case, Jack has 2 scores that are 81, which is his mode.

d) The measure that would make his performance sound good would be the median. The mode and mean are below the score of 84 that he gets for the median. He would want to flaunt this measure to show he performs well.
