What are polynomials?Polynomial is formed composed of the phrases Nominal, which means "terms," and Poly, which means "many." An expression that consists of variables, constants, and exponents that are combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.
Given the function,
g(x) = x⁴ + 3x³ - 19x² - 27x + k
and (x - 2) a factor of g(x)
so g(2) = 0
g(x) = x⁴ + 3x³ - 19x² - 27x + k
g(2) = 2⁴ + 3(2)³ - 19(2)² - 27(2) + k
2⁴ + 3(2)³ - 19(2)² - 27(2) + k = 0
16 + 24 - 76 - 54 + k = 0
k = 90
the function is g(x) = x⁴ + 3x³ - 19x² - 27x + 90
B: -5 is a zero of the function,
f(-5) = 0, or x = -5
so factor is (x + 5)
the two factors are (x + 5)(x - 2)
(x + 5)(x - 2) = x² + 5x - 2x -10
(x + 5)(x - 2) = x² + 3x - 10
to find the other two factors we need to divide the function by
x² + 3x - 10
=> (x⁴ + 3x³ - 19x² - 27x + 90) ÷ (x² + 3x - 10)
quotient after division is
x² - 9 = (x - 3)(x + 3)
The factors of the function are (x - 2)(x + 5)(x - 3)(x + 3)
Hence k = 90, and

The equation used in writing a partial fraction decomposition is given as:
Negative 15 x + 10 / (5 x - 2) = a / (5 x - 2) + b / (5 x - 2).
To determine the values of a and b, we can use a system of equations. This system of equations consists of two equations, one for a and one for b. The equation for a is: Negative 15 x + 10 = a * (5 x - 2). The equation for b is: 0 = b * (5 x - 2). We can solve these equations simultaneously to get the values of a and b.
For example, if x = 1, then the equation for a becomes: Negative 15 + 10 = a * (5 - 2), which simplifies to -5 = a * 9. Therefore, a = -5/9. The equation for b becomes: 0 = b * (5 - 2), which simplifies to 0 = b * 3. Therefore, b = 0.
In summary, the system of equations used to determine the values of a and b is:
Negative 15 x + 10 = a * (5 x - 2) and 0 = b * (5 x - 2). By solving these equations simultaneously, we can get the values of a and b.

the diagram to the right illustrates a hypothetical demand curve representing the relationship between price (in dollars per unit) and quantity (in 1,000s of units per unit of time).
The demand curve graph demonstrates that when prices rise, fewer goods are demanded overall.
The link between price and quantity desired is graphically depicted by the demand curve. It demonstrates how a change in pricing affects how much of an item or service is wanted. The quantity demanded reduces when a good or service's price rises, and vice versa. The quantity demanded falls as the price rises because the demand curve is typically downward sloping. This is due to the fact that when prices are reduced, consumers are more likely to buy products and services. As the price rises, the amount demanded declines, as shown by the hypothetical demand curve that fits this pattern in the diagram to the right. This is a typical pattern observed in the actual world, which is used to guide business and economic decision-making regarding price and output.

n a party, 5 male-female couples attend. the males and females are randomly paired for a dance. what is the probability that exactly two couples are dancing together?
The probability that exactly two couples are dancing together in a party of 5 male-female couples is 1/126, which is a very low probability.
The problem of finding the probability that exactly two couples are dancing together can be solved using the combination formula. The number of ways to choose two couples from the five available couples is given by the binomial coefficient "C(5,2) = 10". The number of ways to arrange the chosen two couples is given by 2! (two factorial), since the order of the couples doesn't matter. The total number of ways to randomly pair the males and females is given by 10!. To find the number of ways in which exactly two couples are dancing together, we need to find the number of arrangements where two couples are dancing together and the remaining three couples are not dancing together.
Therefore, the probability that exactly two couples are dancing together is given by:
(C(5,2) * 2!) / 10! = 1/126
This shows that it is unlikely that exactly two couples will be dancing together in a random pairing of the males and females.

Right ascension (RA) and declination (Dec) are coordinates used in astronomy to precisely describe the location of an object in the sky is total of 62.3358° for the Dec.
RA is measured eastward along the celestial equator from the vernal equinox, which is the point in the sky where the Sun crosses the celestial equator from south to north at the beginning of spring. Dec measures the angle of an object above or below the celestial equator.
In this example, the right ascension is 15 06 53.62 and the declination is 62 20 10.0. This is expressed in terms of hours, minutes, seconds for the RA and degrees, minutes, seconds for the Dec. The RA can be converted to a decimal value by taking the 15 hours and multiplying it by 15 (1 hour = 15°) to get 225°. Then add 6 minutes (6/60 of an hour) which is equal to 10°, and add 53.62 seconds (53.62/3600 of an hour) which is equal to 0.1489°. This gives us a total of 225.1489° for the RA. For the Dec, we take the 62° and add 20 minutes (20/60 of a degree) which is equal to 0.333°, and add 10 seconds (10/3600 of a degree) which is equal to 0.0028°.

City B has a population that can be modeled
B (t) = 350,000 (0. 97)' where t represents the number of years since
2018.
What is the initial population of city A ?
The initial population of city A is 175,000 while its growth rate is 10%. The function that models the population of city B is B(t) = 350,000(0.97)^t, which is a case of exponential decay.
How to find the initial population?Here since nothing else is mentioned we will assume the Initial population of city A to be that of 2018, which is 175,000.
The growth rate of any city will be the percentage increase in its population every year. Here it is mentioned that the population of city A increases by 10% every year. Hence, the growth rate of city A is 10%.
Here we are already given that the function of the population of city B in a year is B(t) = 350,000(0.97)^t.
In model B(t) with every successive increase in time, the value of (0,97)^t will keep on reducing. Due to this, the product of 350,000(0.97)^t will reduce. Hence this is a case of exponential decay.

Running bear left the village and traveled 30 miles on a heading of 30° from this point he went 50 miles on a heading of 220° how far did he end up from the village
Running Bear ended up 29.204 miles from the village.
Running Bear left the village and traveled 30 miles in a direction of 30°. Then he went 50 miles in a direction of 220°. To find out how far he ended up from the village, we need to add up the distances he traveled in both directions.
Think of it like putting two arrows end to end on a piece of paper. The first arrow represents the 30 miles he traveled at 30°, and the second arrow represents the 50 miles he traveled at 220°. The total distance from the village to the final point is equal to the length of the combined arrow.
We can represent the two displacements as vectors in a rectangular coordinate system, with the x-axis as the East-West direction and the y-axis as the North-South direction.
The first displacement, 30 miles at 30°, can be written as a vector in the x and y directions using trigonometry:
x1 = 30 cos 30° = 15
y1 = 30 sin 30° = 15
The second displacement, 50 miles at 220°, can be written as a vector in the x and y directions using trigonometry:
x2 = 50 cos 220° = -25
y2 = 50 sin 220° = -43.301
The total displacement from the village to the final point is found by adding the components of the two vectors:
x = x1 + x2 = 15 - 25 = -10
y = y1 + y2 = 15 - 43.301 = -28.301
Finally, we can use the Pythagorean theorem to find the magnitude (distance) of the total displacement:
d = √(-10)^2 + (-28.301)^2 = √851.121 = 29.204 miles
So, Running Bear ended up 29.204 miles from the village.

a trapezoidal prism, that Pete filled with sand.
12 cm
5cm
7 cm
10 cm
The volume of the trapezoidal prism can be calculated using the formula V = (1/2)(h)(b1 + b2)h, where h is the height, b1 is the length of the top base, and b2 is the length of the bottom base.
In this case, the height is 7 cm, the length of the top base is 10 cm, and the length of the bottom base is 12 cm. Therefore, the volume of the trapezoidal prism is V = (1/2)(7)(10 + 12)7 = 630 cm3.
In addition to calculating the volume of a trapezoidal prism, you can also calculate the surface area of a trapezoidal prism using the formula A = 2h(b1 + b2) + 2(l1 + l2), where h is the height, b1 and b2 are the lengths of the top and bottom bases, and l1 and l2 are the lengths of the lateral faces. The surface area of a trapezoidal prism is the total area of all of the faces of the prism.
Additionally, the lateral surface area of a trapezoidal prism can be calculated by using the formula A = 2h(b1 + b2), where h is the height, b1 and b2 are the lengths of the top and bottom bases. The lateral surface area of a trapezoidal prism is the total area of all of the lateral faces of the prism.

Can anyone help on this?
Answer:
AG=38.84
Step-by-step explanation:
Follow the steps in the image
-Hope this helped
Step-by-step explanation:
I just answered this. how often did you post it ?
the "incenter" means that this is the center point of the inscribed circle that is completely inside the triangle and touches every side in exactly one point.
therefore, all right-angled connections from that point to a side are equally long (the radius is the inscribed circle).
therefore,
GB = GF = GD
we know GF = 22
so, GB = 22
and now we use Pythagoras to find AG in the right-angled triangle ABG :
AG² = AB² + GB² = 32² + 22² = 1024 + 484 = 1508
AG = sqrt(1508) = 38.83297568...
if you round to hundredths : 38.83

The equation has been verified and the solution has been obtained by using trigonometric identities.
What are trigonometric identities?
Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions. There are numerous distinctive trigonometric identities that relate a triangle's side length and angle.
We are given cotθ/1-tanθ + tanθ/1-cotθ = 1 + tanθ + cotθ
Solving the LHS, we get
⇒ [(cosθ/sinθ)/1-(sinθ/cosθ)] + [(sinθ/cosθ)/1-(cosθ/sinθ)]
⇒ [(cosθ/sinθ)/[(cosθ-sinθ)/cosθ]] + [(sinθ/cosθ)/[(sinθ-cosθ)/sinθ)]]
⇒ [cos²θ/(cosθ-sinθ)sinθ] + [sin²θ/(sinθ-cosθ)cosθ]
⇒-[cos²θ/(sinθ-cosθ)sinθ] + [sin²θ/(sinθ-cosθ)cosθ]
⇒[sin²θ/(sinθ-cosθ)cosθ] - [cos²θ/(sinθ-cosθ)sinθ]
⇒(sin³θ - cos³θ)/(sinθ-cosθ)sinθcosθ
⇒(sinθ - cosθ)(sin²θ + sinθcosθ + cos²θ)/(sinθ-cosθ)sinθcosθ
⇒(sin²θ + sinθcosθ + cos²θ)/sinθcosθ
⇒sin²θ/sinθcosθ + sinθcosθ/sinθcosθ + cos²θ/sinθcosθ
⇒tanθ + 1 + cotθ
⇒1 + tanθ + cotθ = RHS
Hence, the expression is verified.

In testing the equality of population proportions using chi-square, how many categories or populations do you need to be able to perform this analysis? at least 2 at least 4 greater than 3 at least 3
In testing the equality of population proportions using chi-square, at least 3 categories or populations need to be able to perform this analysis
Now, According to the question:
A chi-square test for equality of two proportions is exactly the same thing as a z-test. The chi-squared distribution with one degree of freedom is just that of a normal deviate, squared. You're basically just repeating the chi-squared test on a subset of the contingency table.
The chi-square test is used to compare more than two independent populations. The test is pretty similar to that of two population proportions except for the fact that the contingency table involved in the study includes 2 rows and c number of columns indicating the number of populations.

Complete the statement regarding types of economies in a blank system , supply and demand forces affect the production and consumption decisions. There is little to no blank control in such a system
The statement is referring to a market economy, where supply and demand forces affect the production and consumption decisions and there is little to no government control in such a system.
In a market economy, individuals and businesses make the decisions regarding production and consumption, and prices are determined by the interaction of supply and demand. The market is seen as the most efficient allocation mechanism, as prices communicate information about relative scarcities and help to direct resources to their most valuable uses. However, market economies may result in income inequality and market failures, where the market fails to allocate resources efficiently. Government intervention in a market economy is limited to correcting market failures and ensuring a level playing field.

Find a domain for the quantifier in ∃x∃y(x ≠ y ∧ ∀z((z = x) ∨ (z = y))) uch that thi tatement i true
So, the domain for the quantifier in ∃x∃y(x ≠ y ∧ ∀z((z = x) ∨ (z = y))) is the set of all non-empty sets.
The quantifier ∃x∃y(x ≠ y ∧ ∀z((z = x) ∨ (z = y))) is a statement in first-order logic that says "there exists x and there exists y such that x is not equal to y and for all z, z is equal to x or z is equal to y".
The domain for this quantifier is the set of all values for which the statement inside the quantifier is true.
In this case, the domain for the quantifier is the set of all non-empty sets, since for any non-empty set, we can find at least two distinct elements x and y, such that x is not equal to y and for any element z in the set, either z is equal to x or z is equal to y.
So, the domain for the quantifier in ∃x∃y(x ≠ y ∧ ∀z((z = x) ∨ (z = y))) is the set of all non-empty sets.
