If 2+[tex]\sqrt{3}[/tex] is a polynomial root, then the another root of the polynomial will be 2 -[tex]\sqrt{3}[/tex]
The root of the polynomial = 2 +[tex]\sqrt{3}[/tex]
We know by using the quadratic equation we can find the solution of the polynomial
The quadratic equation of the polynomial
= [tex]\frac{-b+/-\sqrt{b^2-4ac} }{2a}[/tex]
Then the root of the polynomial is [tex]\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex] and [tex]\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex]
Here one root is given that 2 + [tex]\sqrt{3}[/tex]
Then using the quadratic equation of the polynomial, the other root of the polynomial will be the conjugate of the given root.
The other root of the polynomial = 2 - [tex]\sqrt{3}[/tex]
Hence, If 2 + [tex]\sqrt{3}[/tex] is a polynomial root, then the another root of the polynomial will be 2 - [tex]\sqrt{3}[/tex]

What is the slope-intercept equation of the line below?y-intercept = (0, 3)5slope =4
Step-by-step explanation:
the slope-intercept form is
y = ax + b
a is the slope, b is the y- intercept (the y-value when x = 0).
so, the equation is
y = -5/4 x + 3

A probability experiment consists of rolling a 6-sided die, numbered 1 to 6. Find the probability of the event below.
rolling a number less than 6
According to the solving the Probability of the event below is as:
= 0.8333
What is probability?Probability is the possibility that an event will occur given all the potential outcomes. A decision-maker considers the likelihood of a result to be important. Decisions will be made better as potential outcomes are better understood.
The purpose of probability:Information on possibility of occurrence is provided by probability. For instance, meteorologists can forecast the likelihood of rain by looking at weather patterns. Probability theory is utilized in epidemiology to comprehend how exposures as well as the risk of health impacts are related.
According to the given data:The probability of rolling a number less than 6.
There are six sides to the die with numbers on each side of (1, 2, 3, 4, 5, 6)
There is a total of six numbers and five ae below six in value.
So,
P(X < 6) = 5/6

The midpoint of AB is (2,7) and point A is located at (5,-3).
What are the coordinates of point B?
The coordinates of point B =(5,10)
what is coordinates?
Coordinates are a set of values which helps to show the exact position of a point in the coordinates plane.
step - by - step explanation
5-2 = 3
2-3= -1 = the x coordinate of B
-7-3= -10
-7-10 = -13 = the y coordinate of B
(-1, -13) is the point B
A is 3 to the right of the midpoint ,so B is 5 to the left to the midpoint
A is 10 up from the midpoint so B is 10 down from the midpoint.
so the coordinates of point B is (5,10)

The vertices of a figure are F(1, 2), G(3,5),and H(3, 2). Rotate the figure 180° about the origin. Find the coordinates of the image.
The coordinates of the vertices after the image is rotated about origin will be -
F(1, 2) → F'(-1, -2)
G(3, 5) → G'(-3, -5)
H(3, 2) → H'(-3, -2)
What is rotation of figure?
A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction.
Given are the vertices of a figure as → F(1, 2), G(3,5) and H(3, 2).
Since, it is not given in which direction the figure is rotated, we will consider it to be rotated in anti - clockwise direction about the origin. When we rotate a coordinate point by 180 degrees in counterclockwise direction about the origin, then the point A(x ,y) becomes A'(-x ,-y).
The new coordinates will be -
F(1, 2) → F'(-1, -2)
G(3, 5) → G'(-3, -5)
H(3, 2) → H'(-3, -2)
Therefore, the coordinates of the vertices after the image is rotated about origin will be -
F(1, 2) → F'(-1, -2)
G(3, 5) → G'(-3, -5)
H(3, 2) → H'(-3, -2)

How to determine the Preferred and common stock?Year 1
Preference Shares = Number of shares × Par value ×%
Preference Shares = 10,000 ×100 × 2%
Preference Shares = $20,000
Common Shareholders:
Common Shareholders = $20,000 - $10,000
Common Shareholders = $10,000
Year 2
Preference Shares = $30,000
Common Shareholders = $0
Year 3
Preference Shares = $20,000 + ($20,000 - $10,000)
Preference Shares = $20,000 + $10,000
Preference Shares = $30,000
Common Shareholders:
Common Shareholders = $45,000 - $30,000
Common Shareholders = $15,000
Therefore year 1 has the amount of $20,000 as preferred stock and $10,000 as common stock.

In order to find the correlation coefficient r, we can use the formula:

ASAP FREE PONTS! HELP! The linear model represents the height, f(x), of a water balloon thrown off the roof of a building over time, x, measured in seconds. Use the constraints of the real-world situation to predict the height of the water balloon at 15 seconds. Use complete sentences to support your answer.
The height of the water balloon at 15 seconds based on the potential rupturing effect of the balloon's initial gravitational potential energy on the membrane of the balloon upon impact with the ground and that addition forces are not added, is at the ground level or zero feet.
What is gravitational potential energy?Gravitational potential energy is the energy possessed by a body by virtue of its elevation above ground level.
The points on the path of the water balloon thrown from the building's roof are;
(0, 4), (2, 7), (7, 5), (6, 4), (9, 1), (9.5, 0)
The location of the water balloon, 9.5 seconds after it is thrown off the roof is therefore at the point, h(9.5) = 0 feet, which can be taken as the ground level or base of the building.
According to Newton's third law of motion, which is a physics or natural law, and which states that all bodies remain at rest or continue perpetually in a straight line unless acted upon by a force.
Given that no additional force is specified after the water balloon is thrown from the building, and that a water balloon can be treated as a large drop of water, where the elastic balloon membrane, represents the surface tension holding the large droplet together, we have that the energy of impact of collision of the balloon when it lands, which is obtained from the initial gravitational potential energy of the water balloon, can potentially rupture the membrane, such that the water is spilled and remains on the floor, well after 9.5 seconds, such that at 15 seconds, the height of the balloon remains at ground level.
