I will give the Brainliest answer! PLEASE HELP! The vertices of a triangle are located at the points A (1,1) , B (2,3), C (5,0). The triangle is translated 4 units down, then reflected across the x-axis to obtain triangle A'B'C'. What are the coordinates of the vertices of triangle A'B'C'?

Answers

Answer 1
Final answer:

To find the coordinates of the vertices A'B'C' of the new triangle after translation and reflection, subtract 4 from the y-coordinate of each vertex and change the sign of the y-coordinate.

Explanation:

To find the coordinates of the vertices A'B'C' of the new triangle, we first translate the original triangle 4 units down. This means we subtract 4 from the y-coordinate of each vertex. So, the new coordinates of A', B', and C' are: A' (1, -3), B' (2, -1), and C' (5, -4).

Next, we reflect the translated triangle across the x-axis. To do this, we change the sign of the y-coordinate of each vertex. So, the final coordinates of A'B'C' are: A' (-1, 3), B' (-2, 1), and C' (-5, 4).

Solution of this equation

Answers

2.5y + 3x = 27
5x - 2.5y = 5

Align the variables to make solving this easier.

2.5y + 3x = 27
-2.5y + 5x = 5

You can see that the 2.5y and -2.5y cancel each other out. Then add the 3x and 5x, and 27 + 5.

3x = 27
5x = 5

8x = 32

Divide both sides by 8.

x = 4

Now input that x into one of the equations to get y. 

2.5y + 3(4) = 27
2.5y + 12 = 27
2.5y = 15
y = 6

The answer to this system of equations is x = 4, y = 6. (4, 6)

Answer:A

Step-by-step explanation:

A man can run a mile in 4 minutes. calculate his average speed in kilometers per hour. show your work. (1 mile = 1.61 km)

Answers

1 mile =1.61km

60 minutes per hour

60/4 = 15 ( he can run 15 miles in one hour)

15 x 1.61 = 24.15 km per hour

round your answer if needed

Final answer:

The man's average speed in kilometers per hour is calculated by first converting the distance the man runs to kilometers, based on the 1 mile equals 1.61 kilometers conversion factor, and then converting time to hours, based on the 60 minutes in 1 hour conversion factor. The calculated speed is approximately 24.04 kilometers per hour.

Explanation:

The man runs a mile in 4 minutes. Given that 1 mile equals 1.61 kilometers, we can first change the distance the man runs into kilometers: 1 mile * 1.61 km/mile = 1.61 km. Thus, the man's speed is 1.61 km per 4 minutes.

To convert this speed into kilometers per hour, we need to convert the time from minutes to hours. We know that 1 hour is equivalent to 60 minutes, so 4 minutes is equivalent to 4/60 = 0.067 hours. Therefore, the man's average speed in kilometers per hour is 1.61 km divided by 0.067 hours, which equals about 24.04 km/hr.

If GH is the angle bisector of FGI, which statement about the angle is true

Answers

Final answer:

The angle bisector of a given angle divides it into two equal parts. If GH is the angle bisector of FGI, angle FGH and angle HGI will be equal.

Explanation:

If GH is the angle bisector of FGI, it means that it splits the angle FGI into two equal parts. Hence the angles FGH and HGI are equal.

For example, if angle FGI is 60 degrees, then the angle FGH and HGI (formed as a result of the bisector) would each be 30 degrees because the bisector divides the 60 degrees into two equal parts. This is the fundamental concept of an angle bisector in geometry.

Answers

The given equation is:

4/(x + 2) = 2/x

First we get the value of x by doing cross multiplication so that all variables are in the numerator side:

4 x = 2 (x + 2)

4 x = 2 x + 4

2 x = 4

x = 2

An extraneous solution is one in which if we plug in the value of x back into the equation, the resulting values would be wrong.

Plug x = 2 back into the original equation:

4 / (2 + 2) = 2 / 2

4 / 4 = 2 / 2

The annual Gross Domestic Product (GDP) of a country is the value of all of the goods and services produced in the country during a year. During the period 1985-1999, the Gross Domestic Product of the United States grew about 3.2% per year, measured in 1996 dollars. In 1985, the GDP was $577 billion. I what year did/or will the GDP equal $1.6 trillion?

Answers

The increase indicates a compound growth of 3.2% per year.
The multiplier is given by 100%+3.2% = 103.2% = 1.032

The initial amount of GDP is 577 billion

We are looking to find in how many years since 1985 that the GDP equals to 1.6 trillion, this is  1.6×10³ billion

The formula for a compound growth/decay is given as
[tex] A_{n}= A_{o} (Multiplier)^{n} [/tex], where [tex] A_{n} [/tex] is the final value and  [tex] A_{o} [/tex] is the intial value.

We are looking to find 'n'

1.6×10³ = 577(1.032)ⁿ
(1.6×10³) ÷ 577 = 1.032ⁿ
1060/577 = 1.032ⁿ ⇒ take log both sides
log( 1060/577 ) = log (1.032)ⁿ
log (1060/577) ÷ log (1.032) = n
n = 19.31 ≈ 19 years

The year when GDP achieves 1.6 trillion is 19 years from 1985, which will be in 2004, providing the increase rates stays the same.

Solve 4a+3=11 plz step by step

Answers

Hi,

Again, we want to work on isolating the variable a. Let's start doing this by first getting rid of the 3.

We must do the inverse of the operation, which in this case will be subtraction since the 3 is positive. Also, always remember that when we do something on one side of the equation, we must do it on the other.

4a + 3 - 3 = 11 - 3

4a = 8

Since the 4 is multiplying our variable a, this means the inverse of the operation will be division. To fully isolate a by getting rid of the 4, we will divide by 4 on both sides.

4a / 4 = 8 / 4

a = 2

Hopefully, this helps.

The value of solution of expression is, a = 2

We have to give that,

An expression to simplify,

4a + 3 = 11

Now, Simplify the expression by combining like terms as,

4a + 3 = 11

Subtract 3 on both sides,

4a + 3 - 3 = 11 - 3

4a = 8

Divide 4 into both sides,

a = 8/4

a = 2

Therefore, the solution is, a = 2

The area of a book cover is 63.8 in². The width of the book is the difference of the length and 3 inches. Let x represent the book's length. Which quadratic equation represents the area of the book cover?
x(x - 3) = 63.8
x(3 - x) = 63.8
2x - 3 = 63.8
x + x - 3 = 63.8

Answers

In this item, we are already given that the length of the rectangular book can be represented by the variable x. In this way, the width, which was described to be the difference of the length and 3 inches, can be expressed as x - 3. 

The area of the triangle is rectangle is calculated by multiplying the length, x, and the width, which was derived to be x - 3.

                 Area = Length x width
                 Area = (x)( x - 3)

Putting in the value of the area, we have the final answer as,
               x(x - 3) = 63.8 in²

Hence, the final answer is the first answer. 

The correct quadratic equation representing the area of the book cover is [tex]\( x(x - 3) = 63.8 \)[/tex].

To understand why this is the correct equation, let's break down the information given in the question:

1. The area of the book cover is given as 63.8 square inches.

2. The width of the book is the difference between the length and 3 inches. If we let [tex]\( x \)[/tex] represent the length of the book, then the width can be represented as [tex]\( x - 3 \)[/tex].

3. The area of a rectangle (which is the shape of the book cover) is calculated by multiplying its length by its width.

Using the information above, we can set up the equation for the area of the book cover as follows:

[tex]\[ \text{Area} = \text{length} \times \text{width} \][/tex]

[tex]\[ 63.8 = x \times (x - 3) \][/tex]

Expanding the right side of the equation, we get:

[tex]\[ 63.8 = x^2 - 3x \][/tex]

This is a quadratic equation in standard form. The other options given do not correctly represent the relationship between the length, width, and area of the book cover:

[tex]- \( x(3 - x) = 63.8 \)[/tex] incorrectly represents the width as [tex]\( 3 - x \)[/tex] instead of [tex]\( x - 3 \)[/tex].

[tex]- \( 2x - 3 = 63.8 \)[/tex] is a linear equation, not a quadratic one, and does not represent the area calculation.

[tex]- \( x + x - 3 = 63.8 \)[/tex] simplifies to [tex]\( 2x - 3 = 63.8 \)[/tex], which is also a linear equation and does not represent the area calculation.

When it comes to probability, the answer is always expressed as part of a whole. With that being said, your answer for this problem can be a ratio, fraction or in percentage. Probability is the study of finding the chances or odds of an event happening with the use of statistics. You are already given the statistics of baby girls and baby boys. Note that you are asked to find the probability of the baby being a girl. So, the part here includes the 248, while the whole is 248+13 = 261. Therefore, the probability is 248/261 or 0.95 or 95%. That means that the likelihood of having a girl baby using this technique is very high.
