Is 3x² 8x 15 Factorisable?

Answers

The equation 3x² - 8x - 15 is not factorizable.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

3x² - 8x  - 15

This is in the form of ax² + bx + c.

We will find the determinant D = b² - 4ac

If D = 0 or D = perfect square

The equation is factorizable.

Now,

a = 3

b = -8

c = -15

D = (-8)² - 4 x 3 x (-15)

D = 64 + 180

D = 244

This is not a zero nor a perfect square.

Thus,

3x² - 8x - 15 is not factorizable.

How do you do 3 terms in binomial expansion?

Answers

The solution of the expression with three terms using binomial theorem can be solved by supposition and resubstituting the value.

Let us consider an example of three terms :

( 1 + x + x² ) ³

Use binomial theorem and expand the given expression:

Standard form of binomial expansion is :

( a + b )ⁿ = ⁿC₀aⁿb⁰ +  ⁿC₁aⁿ⁻¹b¹ + ⁿC₂aⁿ⁻²b² +..............+  ⁿCₙa⁰bⁿ

Let us consider x + x² = y

( 1 + y )³

=³C₀1³y⁰ +  ³C₁1³⁻¹y¹ + ³C₂1³⁻²y² +  ³C₃1⁰y³

= 1 + 3y + 3y² + y³

Resubstitute the value of y = x + x² we get,

= 1 + 3(x + x²) + 3(x + x²)² + (x + x²)³

= 1 + 3x + 3x² + 3( x² + 2x³ + x⁴) + ³C₀x³(x²)⁰ +  ³C₁x³⁻¹(x²)¹ + ³C₂(x)³⁻²(x²)² +  ³C₃x⁰(x²)³

resolve into partial fraction x^2+1/x^3+1​​

Answers

First we have to factorise the denominator [tex]\rm{x^3+1.}[/tex]

It can be factorised as,

[tex]\rm{x^3+1=(x+1)(x^2-x+1)}[/tex]

Then the fraction can be written as,

[tex]\longrightarrow\rm{\dfrac{x^2+1}{x^3+1}=\dfrac{x^2+1}{(x+1)(x^2-x+1)}\quad\dots(1)}[/tex]

This fraction can be resolved into partial fractions by writing it as the sum of a fraction having denominator [tex]\rm{x+1}[/tex] and a fraction having denominator [tex]\rm{x^2-x+1.}[/tex]

Since [tex]\rm{x+1}[/tex] is a first degree polynomial, the numerator of the fraction having this term as denominator should be a zero degree polynomial, or a constant term, assumed as [tex]\rm{A.}[/tex]

Since [tex]\rm{x^2-x+1}[/tex] is a second degree polynomial, the numerator of the fraction having this term as denominator should be a first degree polynomial, assumed as [tex]\rm{Bx+C.}[/tex]

So let,

[tex]\longrightarrow\rm{\dfrac{x^2+1}{(x+1)(x^2-x+1)}=\dfrac{A}{x+1}+\dfrac{Bx+C}{x^2-x+1}}[/tex]

[tex]\small\text{$\longrightarrow\rm{\dfrac{x^2+1}{(x+1)(x^2-x+1)}=\dfrac{A(x^2-x+1)+(Bx+C)(x+1)}{(x+1)(x^2-x+1)}}$}[/tex]

Equating numerators,

[tex]\longrightarrow\rm{x^2+1=A(x^2-x+1)+(Bx+C)(x+1)}[/tex]

[tex]\small\text{$\longrightarrow\rm{x^2+1}=\cal{(A+B)}\rm{x^2}+\cal{(-A+B+C)}\rm{x}+\cal{(A+C)}$}[/tex]

Equating corresponding coefficients,

[tex]\rm{A+B=1}[/tex]

[tex]\rm{-A+B+C=0}[/tex]

[tex]\rm{A+C=1}[/tex]

Solving these three equations we get,

[tex]\rm{A=\dfrac{2}{3}}[/tex]

[tex]\rm{B=\dfrac{1}{3}}[/tex]

[tex]\rm{C=\dfrac{1}{3}}[/tex]

Thus,

[tex]\small\text{$\longrightarrow\rm{\dfrac{x^2+1}{(x+1)(x^2-x+1)}=\dfrac{2}{3(x+1)}+\dfrac{x+1}{3(x^2-x+1)}}$}[/tex]

[tex]\small\text{$\longrightarrow\rm{\dfrac{x^2+1}{(x+1)(x^2-x+1)}=\dfrac{1}{3}\left[\dfrac{2}{x+1}+\dfrac{x+1}{x^2-x+1}\right]}$}[/tex]

So (1) becomes,

Deion is building a walkway with a width of xx feet to go around a swimming pool that measures 13 feet by 9 feet. If the total area of the pool and the walkway will be 621 square feet, how wide should the walkway be?

Answers

Applying the area of a rectangle, the width of the walkway (x) is: 7 feet.

What is the Area of a Rectangle?

Area of a rectangle = (length)(width)

Total area of the pool and walkway = 621 sq. ft

Length of the pool and walkway = 13 + 2x

Width of the pool and walkway = 9 + 2x

Thus, we will have the equation of the total area as:

(13 + 2x)(9 + 2x) = 300

4x² + 44x + 117 = 621

4x² + 44x + 117 - 621 = 0

4x² + 44x - 504 = 0

Factorize

(x - 7)(x+18) = 0

x = 7

x = -18

The width, x, cannot be negative, so, the width of the walkway (x) would be 7 feet.

(a) calculate the sample proportion. what is the value of the population proportion? (b) develop a 99 percent confidence interval for the population proportion. (c) interpret your findings. cyhegg

Answers

(a) sample proportion is 0.75.

(b) The 99% confidence interval for the population proportion is approximately [0.685, 0.815].

(c) a 99% probability that the true population proportion of voters who would support Maria Wilson is within this range.

What is proportion?

A proportion in math is when two ratios are equivalent, that means they are equal to each other.

(a) To calculate the sample proportion, we need to divide the number of voters who would support Maria Wilson by the total sample size. In this case, the sample proportion is 300/400 = 0.75.

(b) To develop a 99% confidence interval for the population proportion, we can use the following formula:

confidence interval = sample proportion +/- (z-value * standard error)

The standard error of the sample proportion is a measure of the variability of the sample proportion, and is calculated as:

[tex]standard\ error = \sqrt{((sample\ proportion * (1 - sample\\ proportion)) / sample size)}\\\\standard\ error= \sqrt{((0.75 * 0.25) / 400)}\\\\standard\ error= 0.025[/tex]

At a 99% confidence level, the z-value is approximately 2.576.

Substituting these values into the formula for the confidence interval, we get:

confidence interval = 0.75 +/- (2.576 * 0.025)

= 0.75 +/- 0.065

= [0.685, 0.815]

So, The 99% confidence interval for the population proportion is approximately [0.685, 0.815].

(c) The confidence interval tells us that we are 99% confident that the population proportion of voters who would support Maria Wilson in the November election is between 0.685 and 0.815. This means that there is a 99% probability that the true population proportion of voters who would support Maria Wilson is within this range.

Generally it is not possible. But if someone applying for early retirement after being forced to leave their jobs due to an illness or injury. In order to help them pay their costs until their SSDI claim is approved and the waiting period for those benefits has passed, they can start collecting early retirement payments.

Generally speaking, it is not possible to receive both Social Security retirement benefits and Social Security Disability Insurance (SSDI) at the same time. However, if you fulfill the severe financial requirements while receiving SSDI or retirement payments from Social Security, you can be eligible for Supplemental Security Income (SSI).

To fill the gap between when someone must leave the working due to a disability and when they can receive retirement benefits, the Social Security Administration (SSA) established the SSDI program. Because of this, there is only one option to get SSDI and retirement benefits at the same time.

This happens when a person chooses to retire early between the ages of 62 and their full retirement age but is later granted SSDI payments. Some people do this on purpose by applying for early retirement after being forced to leave their jobs due to an illness or injury.

How does ArrayList work?

ArrayList is like an array behind the scenes as it’s backed by an array of type java.lang.Object in java.

Normally arrays are fixed in size which means the number of elements that can be added are fixed and cannot be increased once created. ArrayList can dynamically increase in size once the array that backs is full so, these way we won’t encounter runtime exceptions.

When we say list.get(0), it’s equivalent to array[0]. It can be said the ArrayList is a kind of more convenient way to use dynamic arrays.

What are the mean and standard deviation of the distribution of rs?

Answers

The mean and standard deviation of the distribution of R-S is

B Mean 3 and standard deviation 5

How to find the mean and the standard deviation

The mean is calculated by simply substracting the values

= mean R - means S

= 10 - 7

= 3

standard deviation, SD

standard deviation is solved by the use of radicals and this affects the solution hence it will not be simple subtraction, rather we solve back to remove the radical and hence we get the variance

= (SD, R)² + (SD, S)²

= 4² + 3²

= 16 + 9

= 25

the variance is 25

SD = √variance = √25 = 5

PLEASE HELP! The following text is an excerpt from the essay "The Advantages of Having One Leg" by G.K. Chesterton. Read the text carefully. Then, in a well-developed essay, analyze the rhetorical strategies Chesteron uses to support his purpose.I grant that those who have serious wrongs have a real right to grumble, so long as they grumble about something else. It is a singular fact that if they are sane they almost always do grumble about something else. To talk quite reasonably about your own quite real wrongs is the quickest way to go off your head. But people with great troubles talk about little ones, and the man who complains of the crumpled rose leaf very often has his flesh full of the thorns. But if a man has commonly a very clear and happy daily life then I think we are justified in asking that he shall not make mountains out of molehills. I do not deny that molehills can sometimes be important. Small annoyances have this evil about them, that they can be more abrupt because they are more invisible; they cast no shadow before, they have no atmosphere.No one ever had a mystical premonition that he was going to tumble over a hassock. William III died by falling over a molehill; I do not suppose that with all his varied abilities he could have managed to fall over a mountain. But when all this is allowed for, I repeat that we may ask a happy man (not William III) to put up with pure inconveniences, and even make them part of his happiness. Of positive pain or positive poverty I do not here speak. I speak of those innumerable accidental limitations that are always falling across our pathbad weather, confinement to this or that house or room, failure of appointments or arrangements, waiting at railway stations, missing posts, finding unpunctuality when we want punctuality, or, what is worse, finding punctuality when we don't. It is of the poetic pleasures to be drawn from all these that I singI sing with confidence because I have recently been experimenting in the poetic pleasures which arise from having to sit in one chair with a sprained foot, with the only alternative course of standing on one leg like a storka stork is a poetic simile; therefore I eagerly adopted it.To appreciate anything we must always isolate it, even if the thing itself symbolise something other than isolation. If we wish to see what a house is it must be a house in some uninhabited landscape. If we wish to depict what a man really is we must depict a man alone in a desert or on a dark sea sand. So long as he is a single figure he means all that humanity means; so long as he is solitary he means human society; so long as he is solitary he means sociability and comradeship. Add another figure and the picture is less humannot more so. One is company, two is none. If you wish to symbolise human building draw one dark tower on the horizon; if you wish to symbolise light let there be no star in the sky. Indeed, all through that strangely lit season which we call our day there is but one star in the skya large, fierce star which we call the sun. One sun is splendid; six suns would be only vulgar. One Tower of Giotto is sublime; a row of Towers of Giotto would be only like a row of white posts. The poetry of art is in beholding the single tower; the poetry of nature in seeing the single tree; the poetry of love in following the single woman; the poetry of religion in worshipping the single star. And so, in the same pensive lucidity, I find the poetry of all human anatomy in standing on a single leg. To express complete and perfect leggishness the leg must stand in sublime isolation, like the tower in the wilderness. As Ibsen so finely says, the strongest leg is that which stands most alone.11.
