is 14.875 rational or irrational

These are the quadratic equations:

x4 – 6x2 – 27 = 0

2(x + 5)4 + 2x2 + 5 = 0

6x4 = -x2 + 5

8x4 + 2x2 – 4x = 0

What is a quadratic equation ?

A second-degree polynomial equation, which must contain at least one squared component, is what is known as a quadratic. Quadratic equations is another name for them. The quadratic equation's general form is as follows:

ax² + bx + c = 0

where x is a variable that is unknown and a, b, and c are numerical coefficients.

Given : x4 – 6x2 – 27 = 0

           3x4 = 2x

          2(x + 5)4 + 2x2 + 5 = 0

          6(2x + 4)2 = (2x + 4) + 2

          6x4 = -x2 + 5

          8x4 + 2x2 – 4x = 0

we know that in order to be a quadratic equation at least one expression has squared power.

So, x4 – 6x2 – 27 = 0, 2(x + 5)4 + 2x2 + 5 = 0,    6x4 = -x2 + 5 and 8x4 + 2x2 – 4x = 0 are quadratic equations.

Answer: He bought 20 ice cream bars and 14 popsicle

Step-by-step explanation:

To solve this I used the elimination method, you could use substitution as well

Here are our two equations

x+y=34 Because the total number of ice creams bought must be given to 34 children and no more

2x+5y=128 because that is the cost for each ice cream and the amount he spent

For the elimination method we have to cancel out one of the variables, I decided to cancel out the x, so I multiplied the top equation by -2. So i got -2x-2y=-68

2x+5y=128 Then we get

3y=60 so

y=20

Now we can go back to the first equation and plug in y.

x+20=34

  -20  -20

x=14

So he bought 14 popsicles and 20 ice cream bars.

Step-by-step explanation:

The selling price of the socks will be $12.5.

The cost at which any product is sold is called the selling price of the product.

The selling price of a $15.25 pair of socks with an 18% discount is calculated:-

Discounted price = 15.25 x ( 18 / 100 )

                         = $2.754

Selling price = 15.25 - 2.754 = $12.5

Paul's reasoning is not correct. The fact that there are three possible outcomes (win, lose, or tie) does not necessarily mean that each outcome is equally likely.

Probability is the measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event will not occur and 1 means the event is certain to occur. The probability of an event can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes. It is used in various fields including mathematics, statistics, physics, engineering, finance, and more to help understand and predict the occurrence of events.

Here,

The probability of each outcome depends on various factors, such as the strength of the opposing team, the weather conditions, the health and fitness of the players, and other relevant factors. Therefore, it is not possible to determine the probability of winning based solely on the number of possible outcomes.

Answer:

y = -7x + 3

Step-by-step explanation:

To find the slope intercept equation, isolate y, to put the equation in y = mx + b form

7x = -y + 3

7x - 3 = -y

Rearrange the equation:

-y = 7x - 3

Divide each side by -1:

y = -7x + 3

So, the slope intercept equation is y = -7x + 3

Answer:

y = -7x + 3

Step-by-step explanation:

B) The Rational Root Theorem may be used to identify the potential rational roots of the equation in Part A.

The divisors of 9 with the opposite sign are possibly rational roots.

Then, for each rational root, we can see if it is a factor of the polynomial.

A) The remaining of f(x) divided by (x - a) is R, while the remainder of f(x) divided by (x - a) is 2R.

As a result, we may write the following polynomials:

f(x) = (x - a) (x - a)

Q(x) + R f(x) = (x - a)

Q(x) + 2R

Where Q(x) represents the quotient and R represents the remainder.

By combining the two polynomials, we obtain:

(x - a)

Q(x) + R = (x - a) (x - a)

Q(x) + 2R

When we subtract (x - a)Q(x) from both sides, we get:

R = 2R

R = 0 when we solve for R

As a result, the remaining when f(x) is divided by (x - a) is zero.

That is, (x - a) is a factor of f(x), and f(x) is represented as:

f(x) = (x - a)(x^2 + bx + c)

Comparing the coefficients, we get:

a = -a

b = 2a

c = -9

So we have the following equation:

x^3 - 2x^2 - 18x - 9 = 0

B) If it is a factor, we may use synthetic division to divide the polynomial by the factor, resulting in a new polynomial, which we can continue until we have a polynomial with no rational roots. We can utilize numerical methods such as the bisection method or the Newton-Raphson method to thoroughly solve the problem.

Based on the given table data, the modal day for built-up roads will be Friday and for non-built-up roads will be Sunday.

The modal day for each type of road would be the day of the week that has the highest frequency of accidents. The modal day would be the day of the week that appears most often on the list of accident days for each type of road.

To determine the modal day, you would need to count the number of times each day of the week appears on the list for each type of road. The day with the highest count would be the modal day for that type of road. For example, if Monday appears 5 times, Tuesday appears 3 times, and Wednesday appears 7 times on the list for a particular type of road, then Wednesday would be the modal day for that type of road.

It is important to note that there could be more than one modal day if two or more days have the same highest frequency. For example, if Monday and Wednesday both appear 5 times on the list for a particular type of road, then both Monday and Wednesday would be the modal days for that type of road.

A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation. Let's examine the writing of phrases. The other number is x, and a number is 6 greater than half of it. In a mathematical expression, this proposition is denoted by the equation x/2 + 6.

An algebraic expression in mathematics is an expression created using variables, constant algebraic numbers, and algebraic operations. A good example of an algebraic expression is 3x2 2xy + c.

If the value of 2x² - a*5 when x = 0 is 0, then we can substitute x = 0 into the equation and solve for a.

So,

\(2(0)² - a5 = 0\)

\(-a5 = 0\)

\(a = 0\)

Therefore, the value of a should be 0.

The annual sales of the Hand & Foot Cream are increasing by 151,000 bottles per year. Based on the linear trend equation, the predicted annual sales for year 6 is 1,006,000 bottles.

According to the given linear trend equation F1 = 80 + 151, the constant term 80 represents the initial annual sales at the start of the trend. The coefficient of the independent variable t, which represents the number of years, is 151.

To determine whether the annual sales are increasing or decreasing, we look at the coefficient of t. Since the coefficient is positive (151), it indicates that the annual sales are increasing over time. The coefficient tells us that for every year that passes, the annual sales increase by 151,000 bottles. Therefore, the annual sales are experiencing positive growth.

To predict the annual sales for year 6, we substitute t = 6 into the equation. Plugging in the value, we have F6 = 80 + (151 * 6) = 80 + 906 = 986. Therefore, the predicted annual sales for year 6 is 986,000 bottles.

In conclusion, the annual sales of the Hand & Foot Cream are increasing by 151,000 bottles per year. Based on the linear trend equation, the predicted annual sales for year 6 is 986,000 bottles. This indicates that the product's popularity and demand are growing steadily.

The sensitivity to the drug is R'(x) = 2x(760 - 3x) - 3x^2 = 14300 - 15x^2. The sensitivity to the drug is the rate of change of the reaction with respect to the dosage.

In other words, it is the derivative of the reaction function. The reaction function is R(x) = x^2(760 - 3x), so the derivative of the reaction function is R'(x) = 2x(760 - 3x) - 3x^2.

The derivative of the reaction function tells us how the reaction is changing with respect to the dosage. In this case, the reaction is increasing at a rate of 2x(760 - 3x) - 3x^2. When x = 0, the derivative is 0, so the reaction is not changing. When x = 760/3, the derivative is 0, so the reaction is maximized. When x > 760/3, the derivative is negative, so the reaction is decreasing.

Therefore, the sensitivity to the drug is R'(x) = 14300 - 15x^2.

A chord is a combination of three or more tones (notes) played together.

To determine the notes in a chord, we need to calculate the intervals between the notes. An interval is the distance between two notes. Intervals are measured in half steps (or semitones). A half step corresponds to the interval between two adjacent keys of a piano.

In a major chord, the formula for determining the intervals is 1-3-5. This means the root note (1st note) is a major third (4 half steps) away from the 3rd note and a perfect fifth (7 half steps) away from the 5th note.

For example, if the root note is C, the 3rd note is E and the 5th note is G. The intervals in this chord are C to E (4 half steps) and C to G (7 half steps). Therefore, the chord is a C major chord.

In a minor chord, the formula for determining the intervals is 1-b3-5. This means the root note is a minor third (3 half steps) away from the 3rd note and a perfect fifth (7 half steps) away from the 5th note.

For example, if the root note is F, the 3rd note is Ab and the 5th note is C. The intervals in this chord are F to Ab (3 half steps) and F to C (7 half steps). Therefore, the chord is a F minor chord.

The statement "Any linearly independent set in a vector space is a basis for that space" is false.

For a set to be a basis of a vector space, it must satisfy two conditions,

It must be a linearly independent set.

It must span the entire vector space.

So, a linearly independent set in a vector space is not necessarily a basis for that space if it does not span the entire vector space. For example, the set {(1,0), (0,1)} is linearly independent in the vector space R^2, but it is not a basis for R^2 because it does not span all of R^2. A basis for R^2 is {(1,0), (0,1), (1,1)}.
