How do you find the asymptotes and holes of a rational function?
To find the asymptotes and holes of a rational function, factor the denominator of the function and set it to zero. This will give you the x-values of the holes. To find the asymptotes, take the degree of the numerator and subtract it from the degree of the denominator. This will give you the degree of the asymptote.
To find the asymptotes and holes of a rational function, you must first factor the denominator of the function and set it to zero. This will give you the x-values of the holes, or the values where the function is undefined. To find the asymptotes, take the degree of the numerator and subtract it from the degree of the denominator. This will give you the degree of the asymptote. For example, if the numerator is a second degree polynomial and the denominator is a third degree polynomial, the asymptote will be a first degree polynomial. To find the equation of the asymptote, divide the numerator and denominator by the highest degree term of the denominator. The resulting quotient will be the equation of the asymptote. The asymptotes will be straight lines, so the equation will be in the form of y = mx + b. The holes will be the x-values of the points where the denominator equals zero. The asymptotes and holes will divide the graph of the rational function into distinct regions, and can be used to analyze the behavior of the function.

Find a polynomial function of least degree having only real coefficients, a leading coefficient of 1, and roots of 1 − √6, 1+ √6, and 5-i
(Simplify your answer)
What is polynomial function?
In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only uses non-negative integer powers or only positive integer exponents of a variable. For instance, the polynomial 2x+5 has an exponent of 1.
Since we know that complex solutions ALWAYS come in pairs, the minimal polynomial must include the root of 4-i as an acceptable root..
This leads to a polynomial of ...
p(x) = (x - 5)(x - (4+i))(x - (4-i))
Now we can simplify...
(x - (4+i))(x - (4-i)) --> x2 + [(4+i)+(4-i)]x + (4+i)(4-i) --> x2 + 8x + [ 16 -4i + 4i -i2 ] = x2 + 8x +17
Take this quadratic and multiply by (x-5) to get the final, minimal polynomial...
p(x) = (x-5)(x2 + 8x +17) = x3 + 8x2 + 17x -5x2 + 40x - 85 = x3 + 3x2 + 57x - 85
So p(x) = x3 + 3x2 + 57x - 85
p(x) has only real coefficients, the leading coefficient of 1, and is the smallest to allow for the two solutions requested

What additional information is needed to establish the congruence?
To establish congruence between two geometric figures, it is necessary to have information about their size and shape. This includes information about the lengths of their sides and the measures of their angles. It may also be necessary to know the relative positions of the figures, such as whether they are oriented in the same way or whether one is a reflection of the other.
To show that two figures are congruent, it is usually necessary to use one or more of the following techniques:
Superimpose the figures: This involves placing one figure directly on top of the other so that corresponding parts are aligned. If the figures are congruent, they will fit exactly on top of each other and no gaps or overlaps will be visible.
Use a ruler or other measuring tool: By measuring the lengths of the sides and angles of the two figures, it is possible to determine whether they are congruent. If all of the measures are the same, the figures are congruent.
Use transformations: Congruent figures can be obtained from each other through translations, rotations, and reflections. By applying these transformations to one of the figures, it is possible to determine whether it can be made to match the other figure.
Use geometric principles: There are various geometric principles that can be used to establish the congruence of two figures. For example, the AA (Angle-Angle) Congruence Postulate states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are congruent.

What is an arithmetic operation?The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers.
Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.
As per the data mentioned in the question,
We first need to determine how many plums Jude received. Decide to round everything to the sixteenth.
George is having 3/8 = 6/16
Terry is having 1/4 = 4/16
Samuel is having 3/16
So, remaining will go to Jude = (16 - (6 + 4 + 3))/16 = 3/16
Consequently, if Jude received 3/16 of the plums, and she received 36 plums, 1/16 of the total plums is,
= 36/3 = 12 plums (As a side note, there were 192 plums in total).
George has got 6/16 plums = 6 × 12 = 72

Answer:
The level of irritation for both groups can be compared to see if the new cream had a significant effect.
Step-by-step explanation:
In this experiment, the purpose of having two groups is one being the control group, and one being the group being experimented on. The control group is needed in order to know for sure that it is the cream that is beneficial, instead of an outside factor such as the poison ivy being bad.
By comparing the level of irritation for both groups, it will become apparent if the new cream has a side effect.

What will be the roots of the equation 3x² 7x 5 0?
The roots of the Given quadratic equation are 0.57 and -2.9 solved using the algebraic method.
The given equation is a quadratic equation because the degree of the given equation is 2.
How can one tell whether or not a given equation is a quadratic equation?
A quadratic equation is a two-variable polynomial equation of degree two of the form [tex]f(x) = ax^2+bx+c = 0[/tex] with the variables a, b, and c being real numbers and a not equal to 0. With "a" denoting the leading coefficient and "c" denoting the absolute term of f, it is a quadratic equation in its general form (x). The values of x that fulfil the quadratic equation are known as the roots.
The given equation is 3x²+7x - 5 = 0 a =3,b=7, c =-5
lets roots of the given equation is (α, β).
roots can be found using Shreedhara Acharya's formula.
[tex](\alpha, \beta) = [-b \± \sqrt(b^2 - 4ac) ]/2a[/tex]
α = [-b + √(b^2 – 4ac)]/2a
β = [-b - √(b^2 – 4ac)]/2a
b^2 – 4ac = 49-4*3*(-5) = 49+60 = 109
α = (-7+[tex]\sqrt{109}[/tex])/2*3
α = (-7+10.44)/6
α = 0.57
β = (-7 - 10.44)/6
β = -2.9
So the roots of the Given quadratic equation are 0.57 and -2.9.

which expressions represent the length of side \overline{hi} hi start overline, h, i, end overline? choose 2 answers: choose 2 answers:
The expressions represent the length of side, HI are sqrt(161) and 15 sin(90°- 75°) . So, option (a) and (c) are right answers.
What is Pythagoras theorem?A geometry theorem : the square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides ( i.e base and prependicular) .
Mathematically, (GH)² + (HI)² = (GI)²
We have , provide a triangle GHI , since measure of angle H is 90° so it is a right angled triangle.
We have to calculate the length of side HI , for this we can use either triangular formulae or Pythagoras theorem. Here, we are using Pythagoras theorem,
As we have, GH (prependicular) = 8 unit , GI (hypotenuse) = 15 unit , HI ( base) = ?
(prependicular)²+( base)² = (hypotenuse)²
=> (GH)² + (HI)² = (GI)²
=> (8)² + (HI)² = (15)²
=> (HI)² = (15)² - (8)²
=> (HI)² = 225 - 64 = 161
=> HI = sqrt(161) = 12.68
Using Trigonometric functions,
measure of angle G = 180° - 90° - 75° = 15°
In right triangle GHI, sin 15° = HI /15
=> HI = 15 sin 15° = 15 sin(90°- 75°)
So, the length of side HI is sqrt(161) or 15 sin 15° .
