One term is referred to as a polynomial function (where n = 1), a 2 polynomials (when n = 2), and a 3 polynomials (when n = 3) depending on the value. Example: The polynomial is categorized according to the quantity of terms as: Monomial: One phrase, three times.
How are the polynomials categorized in terms of degree and term count?There are three different forms of polynomials, depending on how many terms they contain. Monomial, binomial, and trinomial are the three. A polynomial can be divided into zero polynomial, straight polynomial, cubic polynomial, and cubic polynomial depending on its degree.
How can you tell what degree a phrase is?
The degrees of a component in the polynomials equation is given as a+b if a and b are the proponents of the many variables in a term. For instance, the polynomial contains the equation x2y5, whose degree is 2+5 and hence equals 7.

A rectangular garden has a length of 57 m and a width of 42 m. How many m2 will decrease the area of a garden, if the ornamental fence with a width of 60 cm will be planted inside its perimeter?
The area of the rectangular garden can be calculated as follows: 57 m * 42 m = 2406 m^2.
The ornamental fence with a width of 60 cm has a width of 0.6 m. If the fence is planted inside the perimeter of the garden, the length of the garden will decrease by 2 * 0.6 m = 1.2 m and the width of the garden will decrease by 2 * 0.6 m = 1.2 m.
So, the new length and width of the garden will be 57 m - 1.2 m = 55.8 m and 42 m - 1.2 m = 40.8 m, respectively.
The new area of the garden can be calculated as follows: 55.8 m * 40.8 m = 2270.784 m^2.
Finally, the decrease in area can be calculated as follows: 2406 m^2 - 2270.784 m^2 = 35.216 m^2.
Therefore, the area of the garden will decrease by 35.216 m^2.
Answer:
The width of the ornamental fence is 60 cm, which is equal to 60/100 = 0.6 meters.
The total length of the ornamental fence that will be planted inside the perimeter of the rectangular garden is 2 * (57 m + 42 m) = 2 * 99 m = 198 m.
The decrease in the area of the garden due to the ornamental fence is 0.6 m * 198 m = 118.8 m^2.

Find the value of X and the length of YZ
Answer: x = 8 and YZ = 19
Step-by-step explanation:
mb i focused on the x between a and y and i forgot the x they were talking about was the x in the equations..
since its a bisector, we know that az = yz therefore 2x + 3 = 3x - 5
2x + 3 = 3x - 5
2x + 8 = 3x
8 = x
now we know the value of x, we can plug it into the equation for yz
3(8) - 5
24 - 5
19
therefore, x = 8 and yz = 19
As part of a survey, 300 girls were asked to name their favorite sport. 12 of the girls named bowling as their favorite. Based upon the results, how many of the next 200 girls surveyed would you expect to choose bowling as their favorite sport?
The number of girls in the next 200 girls surveyed that would choose their favorite sport as bowling are 8 girls.
What is percentage?We must divide the value by the entire value to find the percentage, and then multiply the resulting number by 100.
Given that 300 girls were asked to name their favorite sport. 12 of the girls named bowling as their favorite.
The percentage of girls that selected the sport is thus:
12/ 300 (100) = 4%
For the next 200 girls, calculate the 4% of the number to get the number of girls who like bowling:
200 (4%) = N
N = (200)(4/100)
N = 8
Hence, the number of girls in the next 200 girls surveyed that would choose their favorite sport as bowling are 8 girls.

How to define the linear function?The slope-intercept definition of a linear function is given as follows:
y = mx + b.
In which:
The slope m represents the yearly change.The intercept b represents the production in 1995.The production in 1995 was of 52.7, hence the intercept b is given as follows:

Mercury, gallium, and caesium often have low melting points, except gold. The only liquid metal with a 38 °C melting temperature is mercury.
What are the possible melting points for any metal?They have high melting and boiling points because melting and boiling require a lot of energy to break through the strong metallic connections present in a metal's massive structure.

In general, aluminium is an easy metal to melt, and it is easy to get your hands on. To make aluminum metal shapes, many people melt discarded soda cans made of aluminum. The aluminum should be heated until it melts completely.
Therefore, the melting or boiling point will be higher the more energy is required. Varying metals have different melting and boiling points because the force of attraction between the metal ions differs between them.

A system has three computers. Computer 1 works with a probability of 0.65; computer 2 works with a probability of 0.65; computer 3 works with a probability of 0.87. Suppose that the operations of the computers are independent of each other. Suppose that the system works only if at least one computer is working. What is the probability that the system works? Round your answer to four decimal places.
Probability that the system works is approximately 0.9841.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Let the three events be C₁, C₂ and C₃.
Probability that computer 1 works = P(C₁) = 0.65
Probability that computer 1 does not work = P(C₁') = 1 - 0.65 = 0.35
Probability that computer 2 works = P(C₂) = 0.65
Probability that computer 2 does not work = P(C₂') = 1 - 0.65 = 0.35
Probability that computer 3 works = P(C₃) = 0.87
Probability that computer 3 does not work = P(C₃') = 1 - 0.87 = 0.13
Let the event that at least one of the computer is working is S.
P(S) = 1 - P(no computer is working)
P(no computer is working) = P(C₁' ∩ C₂' ∩ C₃')
We have the operations of the computers are independent of each other.
P(C₁' ∩ C₂' ∩ C₃') = P(C₁') × P(C₂') × P(C₃')
= 0.35 × 0.35 × 0.13
= 0.015925
P(no computer is working) = 0.015925
P(S) = 1 - 0.015925
= 0.984075 ≈ 0.9841
Hence the required probability is 0.9841.

Solve for the length of the unknown side in the following right triangle. (Side AC is the hypotenuse.) Round your answer to two places, where applicable. Side AB Side BC Side AC ? 12 19
The length of the unknown side or, the length of AC = 22.62.
To calculate the length of the unknown side in a right triangle, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides or, in familiar algebraic notation, a2 + b2 = c2.
In this Question, side AC is the hypotenuse, so we can use the Pythagorean theorem to find the length of side AC:
AC^2 = AB^2 + BC^2
We know that AB = 12 and BC = 19, so we can substitute these values into the equation:
AC^2 = 12^2 + 19^2
AC^2 = 144 + 361
AC^2 = 505
To find the length of AC, we can take the square root of 505:
AC = √505
Rounded to two decimal places, the length of AC = 22.62.
