The midpoint of the x-intercepts of f(x) = (x - 2)(x - 4) is (3, 0).
The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.
A compass and straightedge setup can be used to locate the midpoint of the line segment they determine given two points of interest. By initially building a lens out of circular arcs with equal radii centered at the two endpoints and joining the cusps of the lens, one can determine the midpoint of a line segment immersed in a plane. The midpoint of the segment is then the place where the line joining the cusps intersects the segment.

Question 1: The Magnolia trees purchased for planting at the school are 3 feet tall. Research shows that these types of trees grow at an average of 3/4 foot per year Some students misunderstood question #1 and wrote the following equations in point-slope form:
a) y − 3 = 3/4(x-0)
b) y - 6 = 3/4(x-4)
c) y - 4.5 = 3/4(x-2)
d) y - 12 = 3/4(x-12)
e) y - 15= 3/4(x-15)
Is point slope form okay to use to find the height of the trees in this problem?
There is one equation that is incorrect.... determine which one? why is it incorrect?
Creat two new equations written in point slope form
The point slope form is not okay to use to find the height of the trees
The incorrect equation is y - 15= 3/4(x-15) The other equations are y - 3.75 = 3/4(x - 1) and y - 4.5 = 3/4(x - 2)How to determine if the point slope form is okay?From the question, we have the following parameters that can be used in our computation:
Initial height of purchase = 3 feet tallAverage rate = 3/4 foot per yearThe point slope form of a linear equation is represented as
y - y₁ = m(x - x₁)
Where
Slope = m
The point slope form does not show the initial value
So, this form is not okay for the required parameters
How to determine the incorrect equationThe slope-intercept form is given as
y = mx + c
Using the given parameters, we have
y = 3/4x + 3
Subtract 3 from both sides
y - 3 = 3/4x
Rewrite as
y - 3 = 3/4(x - 0)
This equation can be rewritten in any of the following forms
a) y − 3 = 3/4(x-0)b) y - 6 = 3/4(x-4)c) y - 4.5 = 3/4(x-2)d) y - 12 = 3/4(x-12)Hence, the incorrect equation is y - 15= 3/4(x-15)
Two new equations written in point slope formWe have the slope-intercept form to be
y = 3/4x + 3
Set x = 1 and 2, and then solve for y
So, we have
y = 3/4 * 1 + 3 = 3.75
y = 3/4 * 2 + 3 = 4.5
So, the equivalent equations are
y - 3.75 = 3/4(x - 1) and y - 4.5 = 3/4(x - 2)

What are the 7 degree of polynomial?
The degree of a constant polynomial (such as 7) is zero.
The variable's highest power in a polynomial expression is the polynomial's degree.
A polynomial is a mathematical expression made up of more than two algebraic terms, particularly the sum (or difference) of several terms that each contain a different power of a single or several variables (s).
It is a monomial combination that is linear. Since the polynomial can be conceived of as 7x0, the degree of a constant polynomial (such as 7) is zero.
Normally, the degree of the zero polynomial (zero) is regarded as being undefinable.
A polynomial function with a degree of 7 is known as a septic function (also known as a 7th degree polynomial).

The boundary of a park is shaped like a circle. The park has a rectangular playground in the center and 2 square flower beds, one on each side
of the playground. The length of the playground is /and its width is w. The length of each side of the flower beds is a. Which two equivalent
expressions represent the total fencing material required to surround the playground and flower beds? Assume that the playground and beds
do not overlap
2(l+w) + 4a and 2l+2w + 2(2a) are two equivalent expressions which represent the total fencing material required to surround the playground and flower beds.
What are mathematical expressions?Mathematical expressions are a way of representing mathematical ideas, concepts, and operations using symbols and notation. They can take many forms, including numbers, variables, and operators. They can also be combined to create more complex expressions, equations, and formulas.
Explain:
The total fencing material required to surround the playground and flower beds would be the sum of the fencing material for the playground and the fencing material for the flower beds.
So, one possible expression for the total fencing material required to surround the playground and flower beds would be: 2(l+w) + 4a
Another possible expression for the total fencing material required to surround the playground and flower beds would be: 2l+2w + 2(2a)

What is the domain and range of a composite function?
The domain of a composite function is the set of all possible inputs for both functions, and the range is the set of all possible outputs.
A composite function is the combination of two or more functions. The domain of a composite function is the set of all possible inputs for both functions. This means that the domain is the set of all the possible inputs that can be used in either of the functions that make up the composite function. The range of a composite function is the set of all possible outputs. This means that the range is the set of all the possible outputs that can be obtained by the combination of the two or more functions. When graphing a composite function, it is important to remember that the domain and range of the composite function are the union of the domain and range of the individual functions in the composite function. The domain and range of a composite function can be determined by first determining the domains and ranges of the individual functions and then combining them.

A point is marked in a coordinate plane using its coordinates when it is plotted in a coordinate system.
The intersection of the x-axis, a horizontal number line, and the y-axis, a vertical number line, creates a 2D coordinate plane.
At the coordinate plane's origin, where the two axes (plural for axis) intersect, four right angles are formed. On a coordinate plane, a grid is frequently drawn to make it simpler to plot points.
In a 2D coordinate plane, a point's location is represented by an ordered pair of numbers (x, y). An ordered pair of numbers is used to represent the location of a point in a 2D coordinate plane (x, y). The first number in the pair represents the point's location along the x-axis, and the second number represents its location vertically (y-axis).
Count x squares from the origin along the x-axis, then count y squares in the direction of the y-axis to plot the point (x, y) in the coordinate plane.

An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 29 inches, and the length of the base is 18 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch.
Answer:
Perimeter = 78.7 inches
Step-by-step explanation:
From the given question, applying the Pythagoras theorem to one of the congruent triangles formed, we have;
[tex]/hyp/^{2}[/tex] = [tex]/adj 1/^{2}[/tex] + [tex]/adj 2/^{2}[/tex]
= [tex](29)^{2}[/tex] + [tex](9)^{2}[/tex]
=841 + 81
[tex]/hyp/^{2}[/tex] = 922
hyp = [tex]\sqrt{922}[/tex]
= 30.3645
The perimeter of the triangle can be determined as;
perimeter = [tex]l_{1}[/tex] + [tex]l_{2}[/tex] + [tex]l_{3}[/tex]
= 30.3645 + 18 + 30.3645
= 78.729

to find the zeros let f(x) = 0 , that is
3x² + 5x + 2 = 0 ← in standard form
consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × 2 = 6 and sum = + 5
the factors are 3 and 2
use these factors to split the x- term
3x² + 3x + 2x + 2 = 0 ( factor the first/second and third/fourth terms )
3x(x + 1) + 2(x + 1) = 0 ← factor out (x + 1) from each term
(x + 1)(3x + 2) = 0 ← in factored form
equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
3x + 2 = 0 ⇒ 3x = - 2 ⇒ x = - [tex]\frac{2}{3}[/tex]

Answer:
Descending order intercept : y = 5x + 4 , y = 4x + 3 , y = 3x + 2 , y = 2x + 1
Step-by-step explanation:
Linear Equations are in form of 'y = mx + b'.
Here, b is y intercept & it represents autonomous ie constant value of y irrespective of value of x. And, m represents slope ie change in y due to change in x.
Eg : 'y = 2x + 1' has least y intercept ie common autonomous value ie 1. y = 3x + 2 , y = 4x + 3 , y = 5x + 4 ; these have higher & higher y intercepts respectively.
