The higher power of the polynomial equation is its degree when there is one variable. However, if a polynomial comprises numerous variables, the degree of the polynomial can be calculated by adding the powers of the multiple (more than one variable) variables in any terms in the polynomial expression.
Polynomial: A Polynomial is defined as an expression which is composed of variables, constants and exponents, that are combined using mathematical operations such as addition, subtraction, multiplication and division.
Examples:
•Constants. Example: 1, 2, 3, etc.
•Variables. Example: g, h, x, y, etc.
•Exponents: Example: 5 in x5 etc.
Degree of one variable polynomial:
Example: 4x^4+6x^2-2
The degree of the polynomial is 4 as the highest power of variable is 4.
Degree of more than two variables polynomial:
Example: 6x^2yz^3+2x^2y+zx
The degree of the polynomial is 6 as the addition of powers of variables is 6.

Vinegar; 30 milliliters.Italian dressing; 290 milliliters.How much vinegar and Italian dressing should the chef use?The amount of vinegar and Italian dressing which the chef should use are to be determined.
Let the amount of vinegar used be x.
Let the amount of Italian dressing used be y;
Hence, for volume balance; we have;
x + y = 320
For the balance of vinegar; we have;
x + 0.04y = (0.13 × 320)
Hence, by subtracting the second equation from the first; we have;
0.96y = 0.87 × 320.
y = (0.87 × 320) / 0.96
y = 290.
Therefore, since x + y = 320;

The equations of the line are listed according to slope and intercept below:
y = - (5 / 2) · x - 11 / 2 y = 2 · x + 10 y = - 3 · x + 5 y = 0How to derive the equation of line for each case
According to Euclidean geometry, a line can be constructed by knowing the location of two different points set on Cartesian plane. From analytical geometry we find that lines are represented by an equation of the form:
y = m · x + b
Where:
m - Slopex - Independent variable.y - Dependent variable.b - InterceptThe slope can be found by secant line formula:
m = Δy / Δx
Now we proceed to find the equation of the line for each case:
Case 1 - (x₁, y₁) = (3, 2), (x₂, y₂) = (5, 7)
m = (7 - 2) / (5 - 3)
m = 5 / 2
b = y - m · x
b = 2 - (5 / 2) · 3
b = 2 - 15 / 2
b = - 11 / 2
y = - (5 / 2) · x - 11 / 2
Case 2 - (x, y) = (- 3, 4), m = 2
b = y - m · x
b = 4 - 2 · (- 3)
b = 4 + 6
b = 10
y = 2 · x + 10
Case 3 - m = - 3, b = 5
y = - 3 · x + 5
Case 4 - x-intercept: 3, y-intercept: 0

The intersection of a triangle's perpendicular bisectors is called the circumcenter.A triangle's circumcenter is a location that is equally spaced from each of its vertices.The centroid of a triangle is the location where its medians connect.
Triangle's centroid is always within it. The centroid of a triangle is its center of gravity in physical terms. If the triangle is evenly distributed around the plane's surface and you want to balance it by supporting it at only one point, you must do it near the center of gravity.Are the circumcenter and centroid at the same location?

How do you rewrite equivalent expressions?
To rewrite equivalent expression is the fractions with distinct numerators and denominators but the same value are said to be equivalent fractions.
We know that,
The multiplicity of a member of a multiset in mathematics is the number of times the member appears in the multiset. The multiplicity of a root, for instance, is how many times a given polynomial has a root at a particular point.
It's crucial to understand the concept of multiplicity in order to correctly count without mentioning exceptions (for example, double roots counted twice). Thus, "counted with multiplicity" is used.
This can be highlighted by counting the number of different elements, as in "the number of separate roots," if multiplicity is disregarded. However, multiplicity is always taken into account when a set (as opposed to a multiset) is established, therefore the word "different" is not necessary.

A water line enters a house 2.0m below ground. A smaller diameter pipe carries water to a faucet in the house. Water flows at 2.0m in the main line and 7.0m out of the second-floor faucet. Take the density of water to be 1.0 ×10^-3 ^3 If the pressure in the line is 2.00 × 10^5 and the pressure at the faucet is 1.40 × 10^5 , how far above ground is the faucet?
The difference in pressure between the main line and the second floor is 91,100 Pa.
How to calculate difference in pressure between main line and second floor ?Bernoulli's theorem states that a drop in fluid pressure is connected with an increase in fluid velocity if the fluid flows horizontally so that there is no change in gravitational potential energy.
On the basis of the idea of energy conservation, Bernoulli's principle is explained. According to this law, the total amount of mechanical energy in a fluid travelling along a streamline will be the same at every point along that streamline in a steady flow.
Given ,
The settings provided;
The main line's water speed is 2.0 m/s,
The second floor's water speed is 7.0 m/s,
The water's density is 1.0 x 103 kg/m3.
The following formula can be used to compute the pressure difference between the main line and the second level using Bernoulli's equation:
[tex]p_1+1/2pv2/1+pgh1+ = p2+1/2pv2/2+pgh_2[/tex]
[tex]p1- p2 = 1/2pv2/2 - 1/2pv2/1 + pgh2 - pgh1[/tex]
[tex]p1 - p2 = 1/2p(v2/2 - v 2/1) + pg (h2- h1)[/tex]
p1 - p2 = 1/2(1000)(7² - 2²) + (1000 ×9.8)(5 - (-2))
p1 - p2 = 91100 pa
Thus, the difference in pressure between the main line and the second floor is 91,100 Pa.
The complete question is : A water line enters a house 2.0 m below ground. A smaller diameter pipe carries water to a faucet 5.0 m above ground, on the second floor. Water flows at 2.0 m/s in the main line and at 7.0 m/s on the second floor. Take the density of water to be 1.0 × 103 kg/m 3 .
