The point is where the parabola's vertex is (2, -5).
Hence, the axis of symmetry is x = 2, and the vertex is (2, -5).
We change the original function's value of x to 2 and evaluate the equivalent value of y to determine the vertex:
[tex]f(2) = 0.5(2)^2 - 2(2) - 2[/tex]
= 1 - 4 - 2

what is symmetry?
A balanced and proportionate likeness between an object's two halves is referred to as symmetry in geometry. It implies that one half is the other's mirror image. The term "line of symmetry" refers to the fictitious axis or line that can be used to fold a figure into symmetrical halves.
A symmetrical object is one that is equal on both sides. Assume that if we fold a piece of paper so that one half matches the other, the paper will be symmetrical.
from the question:
The fact that the axis of symmetry goes through the vertex of a parabola can be used to determine the axis of symmetry and vertex of the function [tex]f(2) = 0.5(2)^2 - 2(2) - 2[/tex]
The vertical line known as the axis of symmetry separates the parabola into two symmetrical parts. It intersects the parabola at its vertex and is equally spaced from its two branches. The following is the equation for the axis of symmetry:
x = -b/2a
where a and b are the coefficients of the quadratic equation in standard form, [tex]ax^2 + bx + c = 0.[/tex]
In this case, a = 0.5 and b = -2, so the equation of the axis of symmetry is:
x = -(-2)/(2*0.5) = 2
Hence, a vertical line going through x = 2 serves as the axis of symmetry.
We change the original function's value of x to 2 and evaluate the equivalent value of y to determine the vertex:
[tex]f(2) = 0.5(2)^2 - 2(2) - 2[/tex]
= 1 - 4 - 2
= -5
Thus, the point is where the parabola's vertex is located (2, -5).
the axis of symmetry is x = 2

The perimeter of the triangle JKL, obtained using the two tangent theorem, is 138 units
What is the two tangent theorem?The two tangent theorem states the segments from the circle to the point at which two tangents to the circle meet are congruent.
The two tangent with common external point theorem indicates that the relationships between the lengths of the segments are;
5·x - 8 = 8·x - 35
8·x - 35 = 5·x - 8
8·x - 5·x = 35 - 8 = 27
3·x = 27
x = 27/3 = 9
x = 97·y - 9 = 2·y + 11
7·y - 2·y = 11 + 9 = 20
5·y = 20
y = 20/5 = 4
y = 4LO = 32 - (2·y + 11)
Therefore; LO = 32 - (2 × 4 + 11) = 13
LO = 13The two tangents theorem, indicates that we get;
LM = LO = 13The perimeter, P, of the triangle JKL is therefore;
P = (5·x - 8) + (8·x - 35) + (7·y - 9) + (2·y + 11) + LM + LO
P = (5×9 - 8) + (8×9 - 35) + (7×4 - 9) + (2×4 + 11) + 13 + 13 = 138

On January 1, 2012, Chan Enterprises borrowed $100,000 from a bank on a three-year mortgage with an interest rate of 5% per year. On December 30, 2012, Chan paid the bank $36,721. Chan uses US GAAP to prepare its financial statements.
Which of the following items would be decreased by the mortgage payment? (check all that apply)
Answers
Answer:
The following items would be decreased by the mortgage payment:
Notes payable (or long-term debt)
Interest expense
Cash (or checking account, or bank account)
Step-by-step explanation:
The mortgage payment has two components: a principal payment and an interest payment. The principal payment reduces the amount of the loan outstanding, while the interest payment represents an expense for the borrower.
Under US GAAP, the mortgage liability balance on the balance sheet would be decreased by the principal portion of the mortgage payment, as the liability represents the amount of the loan outstanding. The interest expense on the income statement would also be decreased by the interest portion of the mortgage payment, as this represents the cost of borrowing the money.
Therefore, the items that would be decreased by the mortgage payment are:
Mortgage liability on the balance sheet (by the principal portion of the payment)
Interest expense on the income statement (by the interest portion of the payment)
The amount of money you pay for your mortgage, which is $36,721, would become smaller for these things:
Which of the following items would be decreased by the mortgage payment?Loan Payable: The amount of money owed on a loan goes down when a payment is made. So, the amount of money owed for the loan would go down by $36,721.
Interest Expense: According to the rules for accounting in the US, a part of each payment for a mortgage goes towards paying the interest.
Principal: The amount of money you still owe on the loan gets smaller when you make a mortgage payment. So, the amount of money the Principal decreases by is $36,721.
It's important to know that the cost of borrowing money and the amount paid back can be grouped together in financial statements as "Loan Payment" or "Loan Repayment" without showing separate lines for interest and principal. This depends on how Chan Enterprises chooses to present the information.

m4 + m5 + m6 = 2m4 + m5 = 180, which proves that the interior angles of a triangle have a sum of 180 degrees.
What is interior angles of a triangle?Interior angles of a triangle are the angles formed inside a triangle at each of its vertices. The sum of these angles is always 180 degrees in a Euclidean plane.
This statement can be used because lines l and m are parallel, which means that m4 and m6 are corresponding angles and are congruent. This means that m4 = m6. Also, m5 and m4 are alternate interior angles, which means that they are congruent as well.
we can substitute m6 with m4 in the first equation to get:
m4 + m5 + m4 = 180
2m4 + m5 = 180
Therefore, the equation simplifies to:
2(180 - m5) + m5 = 180
360 - 2m5 + m5 = 180
m5 = 180 - 360 + 2m5

Using the expected value of probability formula, the value of Σ[x•P(x)] is -0.65
What is the value of Σ[x•P(x)]The expected value of a probability distribution is a measure of the central tendency of the distribution. It is also known as the mean or the average value of the distribution.
To calculate the expected value, we multiply each possible outcome by its corresponding probability and then sum up the products. Symbolically, if X is a random variable with possible outcomes x1, x2, ..., xn and probabilities p1, p2, ..., pn, then the expected value of X, denoted E(X), is given by:
[tex]E(X) = \sum_{i=1}^{n} x_i p_i[/tex]
To find Σ[x•P(x)] we need to multiply each x-value by its corresponding probability and then sum up the products.
So we have:
Σ[x•P(x)] = (-1)(0.999) + (349)(0.001)
Σ[x•P(x)] = -0.999 + 0.349
Σ[x•P(x)] = -0.65

Find the linear function with the following properties.

f(1)=2
Answers
The slope of a linear function is given by the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are two points on the line.
Using the two given points, we can find the slope of the function as:
m = (2 - 5) / (1 - (-7)) = -3/8
The y-intercept of a linear function is the value of the function when x = 0. To find the y-intercept, we can use the point-slope form of a linear equation:
y - y1 = m(x - x1)
where (x1, y1) is one of the given points and m is the slope we just calculated.
Using the point (1, 2), we can write the equation as:
y - 2 = (-3/8)(x - 1)
Simplifying, we get:
y = (-3/8)x + 19/8
Therefore, the linear function with the given properties is:
f(x) = (-3/8)x + 19/8
We can verify that this function satisfies the given properties by checking that:
f(-7) = (-3/8)(-7) + 19/8 = 5
f(1) = (-3/8)(1) + 19/8 = 2
So the function f(x) = (-3/8)x + 19/8 satisfies the given properties.

Rewrite standard form y=3x^2 + 12x + 14 into vertex form
Answers
Answer:
(2,-2)
Step-by-step explanation:
Answer:
the vertex form of the quadratic equation y=3x^2 + 12x + 14 is y = 3(x + 2)^2 - 2. The vertex of this parabola is located at the point (-2, -2).
Step-by-step explanation:
To rewrite the quadratic equation y=3x^2 + 12x + 14 into vertex form, we need to complete the square.
First, we can factor out the coefficient of x^2, which is 3:
y = 3(x^2 + 4x) + 14
Next, we need to add and subtract a constant term inside the parentheses that will allow us to complete the square. We can do this by adding and subtracting (4/2)^2 = 4:
y = 3(x^2 + 4x + 4 - 4) + 14
Now we can write the first three terms inside the parentheses as a squared expression:
y = 3((x + 2)^2 - 4) + 14
Finally, we can simplify this equation by distributing the 3 and combining like terms:
y = 3(x + 2)^2 - 2
So the vertex form of the quadratic equation y=3x^2 + 12x + 14 is y = 3(x + 2)^2 - 2. The vertex of this parabola is located at the point (-2, -2).

What is surface area
Answers
Given that three factors are given and the surface area is required, this means that we are dealing with a three-dimensional shape. Where the above is a rectangular prism, the surface area = 118 In².
What is the explanation for the above response?
Surface area is the measure of the total area that the surface of a three-dimensional object occupies.
To calculate the surface area of an object, you need to add up the areas of all its faces. The formula for finding the surface area of a rectangular prism, which has three pairs of congruent rectangular faces, is:
Surface area = 2(lw + lh + wh)
where l, w, and h are the length, width, and height of the rectangular prism, respectively.
So, if we have a rectangular prism with the following dimensions:
Length (l) = 3.5 inches
Width (w) = 4 inches
Height (h) = 6 inches
The surface area can be calculated as follows:
Surface area = 2(lw + lh + wh)
= 2(3.5 x 4 + 3.5 x 6 + 4 x 6)
= 2(14 + 21 + 24)
= 2(59)

The triangle inequality theorem, which asserts that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side, must be applied in order to find the potential lengths of the third side of the triangle.
We have sides of 6 cm and 4 cm in this instance. Hence, the third side's length must be smaller than the sum of the first two sides and bigger than the difference between them.
Contrast: 6 - 4 = 2 cm
Sum: 6 + 4 = 10 cm

Find the sum of the first ten terms
Does anyone think they can help me with this?

The sοlutiοn οf the given prοblem οf arithmetic mean cοmes οut tο be 115.0625 is the tοtal οf the first ten terms in the prοvided sequence.
What is an arithmetic mean?A list's typical values, alsο referred tο as the οrganisatiοn ’s gοals, are determined by adding up each value οn the list. The percentage οf list cοmpοnents with the highest density is then used tο adjust these average numbers. Mathematical grοwth trends are cοmparable. The actual average οf the digits 5, 7, as well as 9 is 4, and the number 21 becοmes seven by adding three (there are presently a number οf three-digit numbers).
Here,
The series is a geοmetric sequence with the cοmmοn ratiο r = 3/2 and the first term a = 1. We are instructed tο use the fοllοwing fοrmula tο determine the sum οf the first ten terms:
= >S = a(1 - rⁿ) / (1 - r)
Inputting the numbers prοvided yields:
=> S = 1(1 - (3/2)¹⁰) / (1 - 3/2)
=> S = (1 - 59049/1024) / (-1/2)
=> S = (-59048/1024) * (-2) (-2)
=> S = 115.0625
Cοnsequently, 115.0625 is the tοtal οf the first ten terms in the prοvided sequence.

Therefore , the solution of the given problem of arithmetic mean comes out to be -12 and 7 have an algebraic mean of -2.5.
What is arithmetic mean, exactly?The typical values of a list, which are sometimes referred to because the objectives of an organization, are obtained by adding up each and every item on the list. These average values are then modified using the number of items in the list with the greatest abundance. Growth patterns in mathematics are comparable. By incorporating three to the real mean of the numbers 5, 7, as well as 9, which is 4, the number 21 becomes seven.
Here,
Two numbers are added together and their total is divided by two to determine the arithmetic mean of the numbers.
The arithmetic mean of the integers -12 and 7 is
=> {-12 + 7}/ {2}
=> {-5}/{2}
=> -2.5
As a result, -12 and 7 have an algebraic mean of -2.5.

Multiply (8+12t)(-3-6t)
Answers
Answer:
to multiply (8+12t)(-3-6t), we can use the distributive property and then simplify:
(8+12t)(-3-6t)
= 8(-3) + 8(-6t) + 12t(-3) + 12t(-6t)
= -24 - 48t - 36t + (-72t^2)
= -72t^2 - 84t - 24
Therefore, (8+12t)(-3-6t) = -72t^2 - 84t - 24.

A lightyear is the distance that light travels in one year. The speed of light is about 300 million m/s. The earth is about 150 million km from the sun. How long does it take a beam of light to travel from the sun to the earth?
Answers
The distance from the sun to the earth is approximately 150 million km.
To convert this to meters, we can multiply by 1,000 to get 150 billion meters (1 km = 1000 m).
Using the speed of light of 300 million m/s, we can calculate the time it takes for light to travel from the sun to the earth by dividing the distance by the speed of light:
Time = Distance / Speed of light
Time = 150,000,000,000 m / 300,000,000 m/s
Time = 500 seconds
Therefore, it takes about 500 seconds or 8.3 minutes for a beam of light to travel from the sun to the earth.

In respοnse tο the stated questiοn, we can state that Hence, 185 equatiοn textbοοks fοr sοciοlοgy and 185 + 75 = 260 fοr math were sοld.
What is equatiοn?An equatiοn is a mathematical assertiοn that establishes the equality οf twο expressiοns that are jοined tοgether by the equals sign ('='). Fοr example, 2x – 5 = 13.
2x-5 and 13 are examples οf expressiοns. The letter '=' cοnnects the twο expressiοns. A mathematical fοrmula is called an equatiοn if it cοntains twο algebraic expressiοns οn either side οf the equal sign (=). It shοws hοw the right and left fοrmulas are equivalent tο οne anοther. Any fοrmula will result in L.H.S. = R.H.S. (left side = right side).
Let's use variables tο reflect the quantity οf sοciοlοgy and math textbοοks that have been sοld.
Let x represent hοw many sοciοlοgy textbοοks were sοld.
Then, x + 75 math textbοοks wοuld have been sοld.
Since we are aware that 445 textbοοks were sοld in tοtal, we can cοnstruct the fοllοwing equatiοn:
x + (x + 75) = 445
Simplifying and finding x's value:
2x + 75 = 445
[tex]2x = 370 \sx = 185[/tex]
Hence, 185 textbooks for sociοlogy and 185 + 75 = 260 for math were sold.

Find the common difference
Answers
Answer:
-1, -6, 13, 20 is an arithmetic sequence
d = 7
5, 12, 19, 26 is arithmetic sequence
d = 7
-3 - 9, -27, -81 is not an arithmetic sequence
Step-by-step explanation:
Common difference is the difference between successive terms and must be the same for all terms
-1, -6, 13, 20 is an arithmetic sequence with common difference:
6 - (-1) = 13 - 6 = 20 - 13 = 7
5, 12, 19, 26 is arithmetic sequence with common difference
12- 5 = 19 - 12 = 26 - 19 = 7
-3 - 9, -27, -81 is not an arithmetic sequence
The difference between successive terms is not the same
-9 - (-3) = -9 + 3= -6
but
-27 - (-9) = -27 + 9 = -18
In fact it is a geometric sequence where each term = x previous term
-9 = 3 x -3
-27 = 3 x -9

You deposit $6000 in an account earning 6% interest compounded quarterly. How much will you have in the account in 15 years? Round your answer to the nearest cent.
Answers
Step-by-step explanation:
The formula to calculate the future value of a present value deposit with compounding interest is:
FV = PV × (1 + r/n)^(n*t)
Where:
PV = Present Value (the initial deposit)
r = Annual interest rate (as a decimal)
n = Number of compounding periods per year
t = Number of years
Using this formula, we can calculate the future value of the $6000 deposit after 15 years:
PV = $6000
r = 6% = 0.06
n = 4 (compounded quarterly, i.e. 4 times per year)
t = 15 years
FV = $6000 × (1 + 0.06/4)^(4*15)
FV = $6000 × 1.458^60
FV = $6000 × 6.2565
FV = $37,539.00
Therefore, the future value of the $6000 deposit after 15 years with quarterly compounding at 6% interest rate is $37,539.00.
