Answers

Answer 1

The possible rational zeros of f(x) = [tex]x^{4} + 2x^{3} - 3x^{2} - 4x +20[/tex] are ±1, ±2, ±4, ±5, ±10, ±20.

What is mean of rational zero ?

A rational zero is a rational number, which is a number that can be written as a fraction of two integers. An irrational zero is a number that is not rational, so it has an infinitely non-repeating decimal.

By Rational Zero Theorem,

If P(x) is a polynomial with integer coefficients and if is a zero of P(x) i.e.,(P( ) = 0),

then p is a factor of the constant term of P(x)

q is a factor of the leading coefficient of P(x)

Possible value of rational zero is p/q

Have given, f(x) = [tex]x^{4} + 2x^{3} - 3x^{2} - 4x +20[/tex]

Here, constant term, p = +20

Leading coefficient, q = +1

The factors of the constant term +20 are ±1, ±2, ±4, ±5, ±10, ±20.

The factor of the leading coefficient is ±1.

Therefore , The possible rational zeros of f(x) = [tex]x^{4} + 2x^{3} - 3x^{2} - 4x +20[/tex] are ±1, ±2, ±4, ±5, ±10, ±20.

How do you find the inverse of x and y intercepts?

Answers

When the original graph is mirrored around the line y = x, the inverse function's graph may be determined, the domain of the inverse, f-1(x), corresponds to the range of the original function (x), the x intercept of f-1(x) is the y intercept of f, and the range of the inverse f-1(x) is the domain of f(x) (x).

What is a intercept theorem?

The intercept theorem, also referred to as Thales' theorem, the basic proportionality theorem, or the side splitter theorem, is a crucial concept in basic geometry that discusses the ratios of different line segments that are produced when two intersecting lines are intercepted by a pair of parallels.

It is equivalent to the ratios in similar triangles theorem. It is typically credited to the Greek mathematician Thales. Despite the fact that its first known demonstration may be found in Euclid's Elements, it was known to the ancient Babylonians and Egyptians.

Similarity and the intercept theorem go hand in hand. It is equivalent to the idea of similar triangles in that it may be used to demonstrate both the qualities of similar triangles and the intercept theorem.

Hence, When the original graph is mirrored around the line y = x, the inverse function's graph may be determined, the domain of the inverse, f-1(x), corresponds to the range of the original function (x), the x intercept of f-1(x) is the y intercept of f, and the range of the inverse f-1(x) is the domain of f(x) (x).

What does 5 more than mean?

Answers

'5 more than' means that a number is 5 units greater than the original number, using the concept of addition.

Addition (usually signified by the plus symbol +) is one of the four basic operations of arithmetic, the other three being subtraction, multiplication and division.The addition of two whole numbers results in the total amount or sum of those values combined. The example in the adjacent image shows a combination of three apples and two apples, making a total of five apples. This observation is equivalent to the mathematical expression "3 + 2 = 5" (that is, "3 plus 2 is equal to 5").

Besides counting items, addition can also be defined and executed without referring to concrete objects, using abstractions called numbers instead, such as integers, real numbers and complex numbers. Addition belongs to arithmetic, a branch of mathematics. In algebra, another area of mathematics, addition can also be performed on abstract objects such as vectors, matrices, subspaces and subgroups.

Now, let us understand the meaning.

Let the original number be x.

'5 more than a number' implies x + 5.

This means that the new number, x + 5, is greater than the original number, x, by 5 units. We also have to keep in mind, [tex]x + 5 > x[/tex].

Hence, the final meaning is 5 units greater than the original number.

Calculate Volume Using Density and Mass

The definition of density is the mass of an object per unit of volume. Therefore, using the equation: If you understand the object's density and can weigh it, you can calculate its volume.

volume = weight / density

Volume by Displacement Solver

You might not be able to precisely gauge an object's physical dimensions if it has an unusual shape.

Answers

The correct spelling are of the following words is Caucion :caution ,Isle :aisle and Cents :sents

The scent of her perfume is the signifier, and the feminine and romantic association she makes with the scent is the signified.

In linguistics, the concepts of signifier and signified are seen in Saussure's theory of the sign. A sign is formed by the pair signifier/signified. Signifier is a word, an image, anything that has a material form. Signified is the meaning attributed to the signifier by an individual. That means the same signifier can have different signifieds according to the each person. For Mary, the signifier "floral perfume" presents as its signified the "feminine and romantic" feeling. To a different person -  myself, for instance -, a floral perfume does not have the same meaning. I do not see it as romantic or feminine. Instead, because the sweet smell gives me a headache, that has become my signified for it.

What is the nature of the roots of x² − 3x 4 0?

Answers

The roots of the equation are x = (3 + iÂ√7)/2 and x = (3 - iÂ√7)/2.

The equation x^2 - 3x + 4 = 0 can be factored as (x - 4)(x - 1) = 0.

Therefore, the roots of the equation are x = 4 and x = 1.

To calculate this, we can use the Quadratic Formula:

x = [-b ± Â√(b^2 - 4ac)]/2a

In this equation, a = 1, b = -3, and c = 4

x = [-(-3) ± Â√((-3)^2 - 4(1)(4))]/2(1)

x = [(3) ± Â√(9 - 16)]/2

x = (3 ± Â√(-7))/2

x = (3 ± iÂ√7)/2

What is the standard deviation of 25?

Variance's square root is always the standard deviation. √25 thus equals 5.

Describe the term standard deviation?Both the standard deviation and the variance are indicators of how far data deviates from the mean. Because the results are all in data form or units, S.D. provides accurate results. Variance produces squared data findings, making it challenging to compare to actual data. Therefore, it makes sense to compare findings using S.D. rather than variance.

Saying that the median is 7, the mode is 2, and the variance is squared does not make much sense.

However, it makes sense to state that the data's median, mode, and standard deviation are 7, 2, and 4, respectively.

Variance produces squared findings that make it impossible to compare to actual data without. You can only understand differences from getting S.D.

Answers

3x - 5y=-9 has a [tex]\frac{-3}{5}[/tex] slope.

A line's steepness can be determined by looking at its slope. To find the slope of a line, you need to have the equation of the line in the form y = mx + b, where m is the slope and b is the y-intercept (the point at which the line crosses the y-axis).

To put the equation 3x - 5y = -9 in this form, you can start by isolating the y term on one side of the equation:

3x - 5y = -9

-5y = -3x - 9

y = (-3/5)x - (9/5)

A cannonball is shot with a speed of 90 m/s. Assuming its upward speed at the highest point of its curve is 0 m/s and the flat speed at the highest point of its bend is 45 m/s.

We know that in projectile motion, the horizontal velocity does not change.

Let 'x' be the angle it shot. Then the cosine of the angle x is the ratio of horizontal velocity to the resultant velocity when it is shot. Then we have

cos x = 45 / 90

When supply is equal to the demand we get the equilibrium quantity produced and equilibrium price.

The initial price P0 is less than the equilibrium price and thus there is excess demand of the product and thus there is import. When tariff is removed price again drops increasing the excess demand and thus more product is imported.

Consumer surplus is the amount the customer saves as price set by the supplier is less than the amount the consumer is ready to pay. As the customer is ready to pay at P0, the customer surplus when price drop to P1 is given by area A+B+C+D.
