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°. This gives us a total of 62.3358° for the Dec.

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.

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.

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.

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...

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.

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.

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.

Step-by-step explanation:

The rational, irrational and imaginary zeroes for function c(x) = 18x³ + 9x² - 2x -1 are:

To solve this proble, we will use Rational Root Theorem and Descartes Rules of Signs.

Based on Rational Root Theorem, we can find that the function c(x) has rational roots of:

c(x) = 18x³ + 9x² - 2x -1

possible roots = ± {factors of a₀} / {factors of aₙ}

From the given function, we can use the possible roots concept:

Possible roots = ± factors of 18

                              factors of 1

Possible roots = ± {1, 2, 3, 6, 9, 18}

                                     {1}

We can conculde some possible roots such as: {-18, -9, -6, -3, -2, -1, 1, 2, 3, 6, 9, 18}

Next, we need to confirm which possible roots are the rational roots by subtitute the possible roots into the function c(x). The rational roots will produce the function equals to zero (0).

c(1) = 18(1)³ + 9(1)² - 2(1) -1

c(1) = 18 + 9 - 2 - 1 = 24 --> irrational roots

c(2) = 18(2)³ + 9(2)² - 2(2) -1

c(2) = 18(8) + 9(4) - 2(2) - 1

c(2) = 144 + 36 - 4 - 1 = 175 --> irrational roots

c(3) = 18(3)³ + 9(3)² - 2(3) -1

c(3) = 18(27) + 9(9) - 2(3) - 1 = 560 --> irrational roots

c(6) = 18(6)³ + 9(6)² - 2(6) -1

c(6) = 4.199 --> irrational roots

c(9) = 18(9)³ + 9(9)² - 2(9) -1

c(9) = 13,832 --> irrational roots

c(18) = 18(18)³ + 9(18)² - 2(18) -1

c(18) = 107,855 --> irrational roots

c(-1) = 18(-1)³ + 9(-1)² - 2(-1) -1

c(-1) = -18 - 9 + 2 - 1 = -8 --> irrational roots

c(-2) = 18(-2)³ + 9(-2)² - 2(-2) -1

c(-2) = -105 --> irrational roots

c(-3) = 18(-3)³ + 9(-3)² - 2(-3) -1

c(-3) = -400 --> irrational roots

c(-6) = 18(-6)³ + 9(-6)² - 2(-6) -1

c(-6) = -3,553 --> irrational roots

c(-9) = 18(-9)³ + 9(-9)² - 2(-9) -1

c(-9) = -12,376 --> irrational roots

c(-18) = 18(-18)³ + 9(-18)² - 2(-18) -1

c(-18) = -120,176 --> irrational roots

Next, we will try to use Descartes Rule of Signs:

c(x) = 18x³ + 9x² - 2x -1

c(x) = +18x³ + 9x² - 2x -1

The sign is changing once, then the function c(x) has 1 positive roots.

Next, we change the value of (x) into (-x) and put it into the function:

c(-x) = 18(-x)³ + 9(-x)² - 2(-x) -1

c(-x) = -18x³ + 9x² + 2x -1

The signs are changing twice on between the first and second coefficient and between third and fourth. Hence the funciton c(x) has 2 or zero negative roots.

The value of SAT from the following enumerated data is 7 (option a)

Enumerated data;

A set of named values known as enumeration constants, which are integral constants, make up an enumeration, a data type. Because you must list (enumerate) every value before giving it a name, an enumeration is also known as an enumerated type.

Enumeration refers to the act of counting, reciting, or listing numbers. If he starts with a deep sigh, a waiter's long list of all the various salad dressings can sound a touch hostile. Enumeration occurs while you are reciting a list of items.

The value of k is 90.

The other factor of g(x) is, (x + 5)(x - 3)(x + 3)

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 three other factors of g(x) are (x + 5)(x - 3)(x + 3)

The most appropriate level of measurement for the Monthly Rainfall is (d) Ratio .

Ratio measurement is used for variables where the values have a meaningful order, the differences between them are meaningful, and there is a true zero point. For example, height, weight, or time.

In the case of monthly rainfall,

(i) the values have a meaningful order (more rainfall or less rainfall),

(ii) the differences between the values are meaningful (0.2 inches difference),  

(iii) there is true zero point  (month with 0 inches of rainfall).

Therefore, the most appropriate level of measurement is Ratio .

Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate.

Monthly rainfall: 3.4 in, 3.6 in, 3.8 in, 4 in, and 4.2 in
