prove/show that if a | b and b | a, where a and b are integers, then a = b or a = -b. (20 points)

Answers

The proof of "if a | b and b | a, where a and b are integers, then either a = b or a = -b" is shown below .

The representation "a|b and b|a ", means that "a" is a divisor of "b" and "b" is a divisor of "a".

which means , there exists an integer "c" ; such that b=ac    ...equation(1) and an integer "d" such that a = bd    .....equation(2)

Substituting the first equation into the equation(2) , we get:

⇒ a = bd = (ac)d = adc ;

Since a|a, it must be that either a = adc or adc = -a.

But  "c" and "d" are integers, So , "adc" must also be an integer.

Hence, it must be that adc = a.

Thus , a = adc = a. This implies that d = c = 1, and

So ⇒ a = b .....Equation(3) .

Similarly , if adc = -a, then we have: a = -a

Which implies that a = 0, but since "a" and "b" are integers, they cannot both be 0. So , it must be that a = b   ...equation(4) .

Therefore , On combining equation(3) and equation(4)  , we proved that "if a|b and b|a, where a and b are integers, then either a = b or a = -b" .

The given question is incomplete , the complete question is

Answer: 1 7/10

Step-by-step explanation:

The value of a company’s stock is represented by the expression x2 – 2y and the company’s purchases are modeled by 2x + 5y. The company’s goal is to maintain a stock value of at least $7,000, while keeping the purchases below $1,000. Which system of inequalities represents this scenario?

x2 – 2y > 7000
2x + 5y < 1000

x2 – 2y ≥ 7000
2x + 5y < 1000

x2 – 2y > 7000
2x + 5y ≤ 1000

x2 – 2y ≤ 7000
2x + 5y ≤ 1000

Answers

The solution is Option B.

The system of inequalities is x² - 2y ≥ 7000 and 2x + 5y < 1000

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the first inequality equation be represented as A

Let the second inequality equation be represented as B

Now , value of a company’s stock is represented by the expression x² - 2y

And , company’s goal is to maintain a stock value of at least $ 7,000

So , the inequality is x² - 2y ≥ 7000

And , the company’s purchases are modeled by 2x + 5y

Also , the company's purchases should be below $ 1,000

So , the inequality is 2x + 5y < 1000

Hence , the inequalities are solved

A spherical balloon with radius r inches has a volume V(r) = (4/3) pi r^3. How to find a function that represents the amount of air required to inflate the balloon from a radius of r inches to a radius of r+3 inches?

Answers

The function that represents the amount of air required to inflate the balloon from a radius of r inches to a radius of r+3 inches is f(r) = 12π(r² + 3r + 3).

In this question, we are asked to determine a function for a spherical balloon that represents the amount of air required to inflate the balloon from a radius of r inches to a radius of r+3 inches.

Volume of spherical balloon = V(r) = 4/3 π r³

If the radius of balloon is r+3 inches = V(r+3) = 4/3 π (r+3)³

The amount of air required is the difference between V(r) and V(r+3):

So, f(r) = V(r+3) - V(r) = 4/3 π (r+3)³ - 4/3 π (r)³

                                  = 4/3 π ((r+3)³ -r³)

                                  = 4/3 π (r+3 -r)((r+3)² + r(r+3) + r²)

                                  = 4π(r² + 9 + 6r + r²+3r + r²)

                                  = 4π(3r² + 9r + 9)

                             f(r) = 12π(r² + 3r + 3)

Hence, the function representing is f(r) = 12π(r² + 3r + 3).

Answers

When two linear equations in two variables have no solution, it means that the equations are not compatible. This means that the equations cannot be solved simultaneously, as there is no set of values that can satisfy both equations. This can be seen by graphing the equations on a coordinate plane. If the two lines are parallel, then they will never intersect, and thus, there is no solution. If the two lines are the same line, then they will intersect at every point, and thus, any point on the line is a solution.

In the case of two linear equations in two variables, if the equations are not parallel and not the same line, then the equations will intersect at one point. This point is the solution to the two equations. If the equations are not parallel and not the same line, but do not intersect, then there is no solution. This means that the equations are incompatible and cannot be solved simultaneously.

In summary, two linear equations in two variables have no solution when the equations are incompatible. This means that the equations are either parallel or the same line, but do not intersect. In this case, there is no set of values that can satisfy both equations, and thus, there is no solution.

True or False, the standard deviation is the positive square root of the variance.

Answers

Since, the formula for variance is Variance = (σ)², where σ denotes standard deviation, the statement "the standard deviation is the positive square root of the variance" is false.

What is standard deviation?

The standard deviation is a metric that reveals how much variance from the mean there is, including spread, dispersion, and spread. A "typical" variation from the mean is shown by the standard deviation. Because it uses the data set's original units of measurement, it is a well-liked measure of variability.

The dispersion of the set of data values is measured by the standard deviation. The sigma symbol (σ) serves as its symbol.

This indicates that the data values tend to be more dispersed over a greater range for a higher standard deviation. While a lower number of standard deviation results from data being closer to its mean.

Variance, which is the expectation of the squared standard deviation, is a measure of how widely distributed the data are with respect to their mean.

As a result, the relationship between standard deviation and variance can be expressed numerically as, Variance = (σ)².

Therefore, standard deviation is not square root of variance.

What is meant  by factor?A factor is a number that completely divides another number. To put it another way, if adding two whole numbers results in a product, then the numbers we are adding are factors of the product because the product is divisible by them.The exact divisors of a given number are known as factors. Factors are also the numbers that can be combined in the right ways to multiply to get the original number. The sides of every scaled copy are a specific number of times longer than their corresponding sides in the original. This figure is known as the scaling factor. The size of the copy is influenced by the scale factor. A replica that has a scale factor greater than 1 is bigger than the original.

The above equation's roots are 5 + 3i and 5 - 3i.

This indicates that x - (5+3i) and x - are the two factors of the provided polynomial (5 - 3i). The original statement must be the sum of the elements. We can thus write:

A parallel line has the same slope as the original line, but a different y-intercept. So, we want to find an equation of the form y = mx + b where m = -4 (the slope of the original line) and b is the y-intercept that gives the desired point (-10, 6).

We can find b by plugging in the coordinates of the point (-10, 6) into the equation y = mx + b:

Answers

The range of possible values for the third side of the triangle is d)6 < x < 26.

The third side of an acute triangle must be shorter than the sum of the other two sides and longer than the difference between the other two sides. By using the Pythagorean Theorem, we can find the range of possible values for the third side.

The Pythagorean Theorem states that the sum of the squares of the two sides of a right triangle equals the square of the hypotenuse. So, for this triangle, we have 10^2 + 16^2 = x^2.

Solve for x: x^2 = 256, so x = √256 = 16.

The third side must be shorter than the sum of the other two sides. So, the maximum value for x is 16 + 10 = 26.

The third side must be longer than the difference of the other two sides. So, the minimum value for x is 16 - 10 = 6.

Federal tax breaks: Mortgage interest is deductible on the first $750,000 of the house's purchase price, as are home equity loan interest, property taxes up to $10,000 if married ($5,000 if married filing separately), and various closing fees at the time of purchase.

Greater privacy: Because you own the property, you may renovate it to your desire, something tenants do not have.

Home office: The work-at-home craze may persist after the epidemic has passed, implying that more of us will require a home office. The appropriate configuration affects both comfort and productivity.

Monthly payments that are predictable: A fixed-rate mortgage requires you to pay the same amount each month for principle and interest until the loan is paid off. Rents are subject to rise with each annual lease renewal. Changes in property taxes or homeowner's insurance can affect monthly payments, although not as often as rent hikes.

Stability: People tend to stay in a house they own for a longer period of time, if only because purchasing, selling, and relocating is difficult.

Adrian measured a line to be 12.8 inches long. If the actual length of the line is 12.7 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?

Answers

The required percent error of the measurement is 0.8%.

What is Error bars?

Error bar, are the line through a point on a graph, axes, which emphasizes the uncertainty or variation of the corresponding coordinate of the point.

The percent error of Adrian's measurement can be calculated as follows:

(|Measured value - Actual value| / Actual value) * 100

= (|12.8 - 12.7| / 12.7) * 100

= (0.1 / 12.7) * 100

= 0.786%

Rounded to the nearest tenth of a percent, the error is 0.8%.

Answer:6.6%

Step-by-step explanation:

A simple random sample of size n=14 is obtained from a population with μ=64 and σ=19.
​(a) What must be true regarding the distribution of the population in order to use the normal model to compute probabilities involving the sample​ mean? Assuming that this condition is​ true, describe the sampling distribution of overbarx.
​(b) Assuming the normal model can be​ used, determine​P(overbar x < 68.2​).
​(c) Assuming the normal model can be​ used, determine​P(overbar x ≥ 65.6​).

Answers

Part a) A. The population must be normally distributed

Part b) P(overbar x < 68.2​) = 0.7967

Part c)P(overbar x ≥ 65.6​)=  0.3745

Define the term normally distributed?An example of a continuous probability distribution is the normal distribution, in which the majority of data points cluster in the middle of the range while the remaining ones taper off symmetrically toward any extreme. The distribution's mean is another name for the center of the range.

a) Population is normally distributed -

mean (μ) = 64  and a standard deviation (s) =  σ /√n =  19/√14

b) P(overbar x < 68.2​)

Estimate the z score (z).

z = (x -  μ) / s

z = (68.2 - 64) / 19/√14

z = 0.83

Use z table,

P(overbar x < 68.2​) = P(z < 0.83)

P(overbar x < 68.2​) = 0.7967

c)  P(overbar X  ≥  65.6)

Estimate the z score (z).

z = (x -  μ) / s

z = (65.6 - 64) / 19/√14

z = 0.32

Use z table,

P(overbar x ≥  65.6)  =  P(z  ≥  0.32)

                                  = 1 -  P(z  <  0.32)

                                 = 1 - 0.6255

                                 = 0.3745

P(overbar x ≥  65.6)  = 0.3745

Find a vector orthogonal to both 2, 2, 0 and to 0, 2, 5 of the form 1

Answers

The vector orthogonal for both vectors is [tex](20, -10, -4) / \sqrt{444}[/tex] = ([tex]20 / \sqrt{444}[/tex], [tex]-10 / \sqrt{444}[/tex], [tex]-4 / \sqrt{444}[/tex])

What is an orthogonal vector?

An orthogonal vector is a vector that is perpendicular to another vector in a given space. In other words, two vectors are orthogonal if their dot product is equal to zero.

To find a vector orthogonal to both 2, 2, 0 and 0, 2, 5 of the form 1, we can take the cross product of the two vectors, which results in a vector that is orthogonal to both. The cross product of 2, 2, 0 and 0, 2, 5 is given by:

(2, 2, 0) x (0, 2, 5) = (20, -10, -4)

So, a vector orthogonal to both 2, 2, 0 and 0, 2, 5 is given by (20, -10, -4). We can normalize this vector by dividing it by its magnitude, which is equal to sqrt(20^2 + (-10)^2 + (-4)^2) = sqrt(444). The normalized vector will be of the form 1:

[tex](20, -10, -4) / \sqrt{444}[/tex] = ([tex]20 / \sqrt{444}[/tex], [tex]-10 / \sqrt{444}[/tex], [tex]-4 / \sqrt{444}[/tex])

Hence, the vector orthogonal for both vectors is [tex](20, -10, -4) / \sqrt{444}[/tex] = ([tex]20 / \sqrt{444}[/tex], [tex]-10 / \sqrt{444}[/tex], [tex]-4 / \sqrt{444}[/tex]).

Protons are a type of subatomic particle with a positive charge. With more electrons than protons, the particle is negatively charged.

Is proton and electron are same?A subatomic particle with a negative charge is an electron. A subatomic particle having a positive charge is called a proton. The strong nuclear force holds protons together in the nucleus of an atom. A type of subatomic particle without charge is the neutron (they are neutral).The atomic number is equal to the number of protons in the atom's nucleus (Z). In a neutral atom, there are exactly as many electrons as protons. The total number of protons and neutrons in the atom's nucleus is equal to the mass number (M) of the atom.A negatively charged subatomic particle known as an electron can either be free or attached to an atom (not bound).

find the difference quotient of f; that is, find

Answers

The difference quotient of f; that is, [tex]\frac{f(x+h)-f(x)}{h}[/tex], h ≠ 0 for the function f(x) = x^2 - 9x + 6 is 2x - 9.

The function is f(x) = x^2 - 9x + 6.

We have to determine the differential equation; that is [tex]\frac{f(x+h)-f(x)}{h}[/tex].

To find the value of f(x+h) substitute x+h in place of x the the function.

f(x+h) = (x+h)^2 - 9(x+h) + 6

Solving

F(x+h) = x^2 + 2xh + h^2 - 9x - 9h + 6

Now putting the value

[tex]\frac{f(x+h)-f(x)}{h} = \frac{(x^2 + 2xh + h^2 - 9x - 9h + 6)-(x^2 - 9x + 6)}{h}[/tex]

Simplify

[tex]\frac{f(x+h)-f(x)}{h} = \frac{x^2 + 2xh + h^2 - 9x - 9h + 6-x^2 + 9x - 6}{h}[/tex]

[tex]\frac{f(x+h)-f(x)}{h} = \frac{2xh + h^2 - 9h}{h}[/tex]

Taking common h on both side, we get

[tex]\frac{f(x+h)-f(x)}{h} = \frac{h(2x + h - 9)}{h}[/tex]

[tex]\frac{f(x+h)-f(x)}{h}[/tex] = (2x + h - 9)

Now setting the limit h tends to 0

[tex]\lim_{h\rightarrow 0}\frac{f(x+h)-f(x)}{h}[/tex] = [tex]\lim_{h\rightarrow 0}[/tex](2x + h - 9)

Now putting h = 0, we get

[tex]\lim_{h\rightarrow 0}\frac{f(x+h)-f(x)}{h}[/tex] = 2x - 9

Naomi wants to save $100 000, so she makes quarterly payments of$1500 into an account that earns 4.4%/a compounded quarterly. How long will it take her to reach her goal?

Answers

It will take Naomi approximately 4 quarters and 8 months, or 4.67 quarters to reach her goal.

How to calculate?

To find the number of quarters required to reach $100,000 with a quarterly payment of $1500 and an interest rate of 4.4% compounded quarterly, we will  use the  formula below:

N = log((A / P) + 1) / log(1 + r)

Where:

N = number of quarters

A = target amount ($100,000)

P = payment per quarter ($1500)

r = interest rate per quarter (4.4%/4 = 1.1%)

Substituting the values, we have that

N = log((100,000 / 1500) + 1) / log(1 + 0.011)

N = log(66.67) / log(1.011)

N = 4.67 quarters

In conclusion, It will take Naomi approximately 4 quarters and 8 months, or 4.67 quarters to reach her goal.
