The answer choice which must be a factor of the polynomial in discuss is; (x - 1).
What must be a factor of the polynomial as described?It follows from the vertex form equation of a parabola; f(x) = a ( x - h )² + k where the vertex of the parabola is; (h, k).
Therefore, the equation of the parabola in discuss is;
f(x) = a (x - 3.5)² + 3.
Recall that the x coordinates of the vertex, h is given by; h = (p + q) / 2
where p and q are the zeroes of the quadratic function.
Therefore, since one of the zeroes is given as; 6 ( from (6, 0) ); it follows that the second zero can be determined as follows;
3.5 = ( 6 + q ) / 2
7 = 6 + q
q = 1
Therefore, since the second zero is; 1. It follows that the associated factor as required is; ( x - 1 ).

The straight-line distance between Edentown and Newberg is 90 miles. The correct option is the third option 90 miles
Calculating the straight-line distance between two townsFrom the question, we are to determine the possible straight-line distance between Edentown and Newberg if the three towns form a right triangle.
Let the straight-line distance between Edentown and Newberg be x.
Now,
Assume that the straight-line distance between Martville and Newberg is the hypotenuse of the right triangle,
Then,
From the Pythagorean theorem, we can write that
150² = x² + 120²
22500 = x² + 14400
x² = 22500 - 14400
x² = 8100

Explanation:
We want to prove by contradiction that corresponding angles 1 and 5 made by a transversal crossing non-parallel lines are not congruent.
To prove by contradiction, we make an assumption that results in a demonstrably false conclusion. This allows us to conclude the assumption is false.
ProofAssume angles 1 and 5 are congruent.
Then lines m and n are parallel by the converse of the corresponding angles theorem.
Lines m and n are not parallel, hence our assumption must be false.
Angles 1 and 5 are not congruent.
Do this, for example, 3v x 2t =6vt

Equivalent Ratios
Answer:
Equivalent Ratios
Step-by-step explanation:
Two ratios that have the same value are called equivalent ratios. To find an equivalent ratio, multiply or divide both quantities by the same number. It is the same process as finding equivalent fractions.
The equality of two ratios is also known as proportion. The antecedent and consequent values are different.
Equivalent ratios are the same when we compare them. The two quantities of ratio should be of the same kind. To find an equivalent ratio we need to multiply.
Equivalent ratios are just like equivalent fractions. If two ratios have the same value, then they are equivalent, even though they may look very different!
Equivalent ratios or equal ratios are two ratios that express the same relationship between numbers as we covered in our tutorial on scaling up ratios.

Let X be a continuous random variable with the pdf given by f(x)= ax2 for 0 < x ≤ 3. Determine the value of constant 'a' correct to 2 decimal places.
The value of the constant a in f(x) = ax² such that 0 < x ≤ 3 is 0.11
How to determine the value of the constant a?The probability density function is given as
f(x) = ax²
Such that
0 < x ≤ 3
To determine the value of the constant a, we make use of the following equation
[tex]\int\limits^a_b {f(x)} \, dx = 1[/tex]
So, we have:
[tex]\int\limits^3_0 {ax^2} \, dx = 1[/tex]
Factor out the constant
[tex]a\int\limits^3_0 {x^2} \, dx = 1[/tex]
Differentiate the equation
So, we have the following representation
[tex]a\frac{x^3}3 |^3_0 = 1[/tex]
Expand the equation
a[3³ - 0³]/3 = 1
Evaluate the difference
a[3³]/3 = 1
Evaluate the quotient
9a = 1
Divide both sides by 9
a = 0.11

The result of the given terms is -2/5 as per the given question from complex numbers.
What is a complex number?There is a multiplicative inverse for every nonzero complex number. As a result, complex numbers are a field with real numbers as a subfield. The complex numbers also form a two-dimensional real vector space with 1, I as the standard basis.
Because of this standard basis, the complex numbers form a Cartesian plane known as the complex plane. This allows for a geometric interpretation of complex numbers and operations, as well as the expression of geometric features and constructions in terms of complex numbers. Real numbers, for example, constitute the real line, which corresponds to the complex plane's horizontal axis.

How to find P(B | not A)?Probability is defined as the likelihood of a desired event happening.
Given that: P(A) = 0.37, P(B) = 0.43 and P(AandB) = 0.20.
We want to find P(B | not A)
Remember: P(A | B) = P(A n B) / P(B)
Thus, P(B | not A) = P(B and not A) / P(not A)
P(not A) = 1 - P(A) = 1 - 0.37 = 0.63
P(B and not A) = P(B) - P(A and B) = 0.43 - 0.20 = 0.23

How to find the equation of the polynomial?A polynomial of degree N with the n zeros {x₁, x₂, x₃, ..., xₙ} is written as:
P(x) = (x - x₁)*(x - x₂)*...*(x - xₙ)
That is called the factorized form of the polynomial, and we are assuming that the leading coefficient is equal to 1 just for simplicity.
In this case we have 3 zeros {-2, 0, 1}, so the polynomial is of degree 3, and we can write it as:
P(x) = (x + 2)*(x - 0)*(x - 1)
To write the polynomial in the standard form, we need to expand the product:
P(x) = (x + 2)*(x)*(x - 1)
P(x) = (x^2 + 2x)*(x - 1)

Vertex of a quadratic functionA quadratic function is a variable of a polynomial function defined by f(x)=ax² + bx +c, where a≠0
The graphs of these functions correspond to vertical parabolas (symmetric axis parallel to the ordinate axis), with the particularity that:
when a>0, the parabola opens "up".when a<0, the parabola opens "down".The vertex of a quadratic equation or parabola is the highest or lowest point on the graph corresponding to that function. The vertex is calculated as:
The value of -b÷(2a) indicates the value of x of the vertex.Substituting value of x into the function, you get the value of y of the vertex.Vertex in this caseIn this case, the quadratic equation y=2x²−12x+7, where:
a=2b= -12c= 7The value of x of the vertex is calculated as -(-12)÷(2×2)
Solving: -(-12)÷(4)= 12÷4= 3
The value of y of the vertex of the function is calculated as y=2×3²−12×3+7
Solving y= -11
