What step in the construction of copying a line segment ensures that the new line segment has the same length as the original line segment?

Answers

Answer 1

Final answer:

To copy a line segment and ensure it has the same length as the original, use a compass to measure and create a duplicate line segment.

Explanation:

To copy a line segment and ensure that the new line segment has the same length as the original, we can use a compass. Here are the steps:

Place the compass needle on one endpoint of the original line segment.Open the compass to the length of the original line segment.Without changing the compass width, place the compass needle on the other endpoint of the original line segment and draw an arc.Use the compass to measure the same length on the arc and draw a line segment connecting the two marks.

By using this method, we can create a duplicate line segment with the same length as the original.

Which lines are parallel if m4 = m5? Justify your answer.

Answers

Answer:

r and s are parellel

Step-by-step explanation:

The correct answer is that lines 4 and 5 are parallel if [tex]$ m_4 = m_5 $.[/tex]

To justify this answer, we must understand the concept of slope in the context of lines in a plane. The slope of a line, denoted by m is a measure of its steepness and is defined as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line. Mathematically, if two points on a line have coordinates [tex]$ (x_1, y_1) $[/tex] and [tex]$ (x_2, y_2) $,[/tex] then the slope m is given by: [tex]\[ m = \frac{y_2 - y_1}{x_2 - x_1} \][/tex] For two lines to be parallel, they must have the same slope. This is because parallel lines have the same steepness and never intersect. Therefore, if the slope of line 4, [tex]$ m_4 $[/tex], is equal to the slope of line 5, [tex]$ m_5 $[/tex], then lines 4 and 5 are parallel. In mathematical notation, if [tex]$ m_4 = m_5 $,[/tex] then line 4 and line 5 are parallel, which can be written as: [tex]\[ m_4 = m_5 \Rightarrow \text{Line 4} \parallel \text{Line 5} \][/tex] This conclusion is based on the fundamental properties of slopes and parallel lines in Euclidean geometry. If the slopes of two lines are equal, it means that they rise and run at the same rate, and thus, they will maintain a constant distance from each other, never intersecting, which is the definition of parallel lines.

Answers

assuming the problems is |-5.75|, the absolute value is simply 5.75

absolute value measures how far away a value is from 0 on a number line. |1| and |-1| both have an absolute value of 1, because if you graphed them on a number line you'd see that they're both 1 unit away from 0. although -5.75 would be on the left, or negative side, of the 0 on a number line, it is still exactly 5.75 units away, and that's what absolute value measures.

B) 4.90
C) 5.10
D) 5.90

Answers

B) 4.90

Hope that helped :)

Answer: B) 4.90

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Katrina: 69.75 inches tall Allison: 64.85 inches tall.

Since Katrina is taller than Allison, to calculate the how many inches taller is Katrina than Allison, we have to subtract Allison’s height to Katrina’s height:

Mathematically speaking:

69.75 -64.85 = 4.9 inches.

The answer is: 22.4339811320566038 mi.
→ Consider rounding to 22.43 mi.
_______________________________________________________
(Note: Do not forget the units, in "miles", which can be abbreviated as: "mi.").
____________________________________________________________________
Explanation:
_____________________________________________________________________
Let us assume that, at the beginning, Joan is leaving her own house to pick up Kash, first.
_____________________________________________________________________
Then, the answer to our problem is the sum of the length of all sides of the triangle given, remember that each "unit" on the graph represents miles.
_____________________________________________________________________
We can solve this using the Pythagorean theorem:
_____________________________________________________________________
a² + b² = c² ; in which: c = the distance from Joan's house to Kash's house;
b = the distance from Kash's house to Gary's house;
a = the distance from Gary's house to Joan's house;
_____________________________________________________________________
Our answer is the sum of: "a + b + c".
_____________________________________________________________________
Using the graph, we can the determine the values for: "a" and "b";
Using the Pythagorean theorem, we can determine the value for "c";
then we can add: "a + b + c" to determine our answer.
_____________________________________________________________________
From inspecting the graph:
_____________________________________________________________________
b = the distance from Kash's house to Gary's house = 8 mi. [miles] ;
a = the distance from Gary's house to Joan's house = 5 mi. [miles] ;
__________________________________________________________
Using the Pythagorean theorem, we want to solve for "c":
__________________________________________________________
a² + b² = c² ; We substitute our known values for "a" and for "b" :
_____________________________________________________
5² + 8² = c² ; Simplify:
_____________________________________________________
25 + 64 = c² ;

89 = c² ; Take the positive square root of both sides to solve for "c";
_______________________________________________________
√89 = √(c²) ; c = √89 = 9.4339811320566038
_______________________________________________________
Now, we can find our answer:
_______________________________________________________________
a + b + c = 5 + 8 + (9.4339811320566038) = 22.4339811320566038 mi.
→ Consider rounding to 22.43 mi. ;
which is our answer.

Show that f is strictly monotonic on the given interval and therefore has an inverse function on that interval: f(x) = cot(x), (0,pi)

Answers

The derivative is always negative on (0, infinity), therefore , f is decreasing and thus has an inverse on this interval.

Hope This Helped!!! :)

Final answer:

To show that f(x) = cot(x) is strictly monotonic on the interval (0,pi), we need to show that the derivative of f(x) is either strictly positive or strictly negative on that interval.

Explanation:

To show that f(x) = cot(x) is strictly monotonic on the interval (0,pi), we need to show that the derivative of f(x) is either strictly positive or strictly negative on that interval.

The derivative of f(x) can be found using the chain rule as follows:

Find the derivative of cot(x): d(cot(x))/dx = -csc^2(x)Since f(x) = cot(x), the derivative of f(x) is -csc^2(x).

Now, let's consider the interval (0,pi). The function f(x) = cot(x) is defined on this interval, and its derivative -csc^2(x) is strictly negative for all x in (0,pi). Therefore, f(x) is strictly decreasing on the interval (0,pi), which means it is strictly monotonic.

Since f(x) is strictly monotonic on the interval (0,pi), it has an inverse function on that interval. The inverse function of f(x) is denoted as f^{-1}(x).

The answer is C. Solve it like you would a equation with b for the variable. You first, distribute the x into the problem in the parenthesis: R=Ax+Bx. Then, you realize that Ax is positive and the to remove it is to subtract Ax and will leave with Bx on the right side of this equation (remember, what you do on one side, you must do to the other in order to keep it balanced). That means you must subtract Ax from the left side of the equation also, leaving you with: R-Ax=Bx. Now, to get that B alone, you must realize that the right hand side of the equation is a multiplication problem so the only way to remove it is to divide right? So the right hand side now is only B. REMEMBER! You must do to both sides of the equation so you must divide the left hand side of the equation by X. And you are left with R - Ax/ X. Same as (R-Ax)/x. So choice c is the correct answer.

Describe how the graph of y=log (10 000x) is related to the graph of y=log x

Answers

Background: log (a . b) = log a + log b
hence log(10000x) = log 10000 + log x but we know that log 10000 = 4
= 4 + log x
therefore the graph of log(10000x) is just the graph of log x transposed by 4

graph of y=log (10 000x) is related to the graph of y=log x is transposed by 4 units.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given graphs of y=log (10 000x)

y equal to ten thousand of x

We know a property of log.

logab=loga+logb

Log ab equal to log a plus log b.

So log (10 000x) =log 10000+log x

=4+logx

Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph.

So the graph of log (10 000x) is transposed by 4 units.

If x > 1, then which of the following has the LEAST value?

Answers

Final answer:

If x > 1, then the expression (0.25 - x) will have the least value when x is equal to 1.

Explanation:

If x > 1, then the expression (0.25 - x) will be negative. When comparing negative values, the one with the least absolute value will have the least value. Therefore, to find the expression with the least value, we want to find the largest negative value for (0.25 - x). Since x > 1, the largest negative value for (0.25 - x) would occur when x is closest to its minimum value, which is 1. Therefore, the expression (0.25 - x) will have the least value when x is equal to 1.

First, you have to find the area of the rectangle. I guess, just now,
that means the one who has to do that is me.

We know that it's a rectangle, because they told us so.
The corners are located at
(1, 4)
(4, 7)
(8, 3)
and
(5, 0).

Do you remember how to find the distance between 2 points ?

   Distance = √ (difference-in-'x' ² + difference-in-'y' ²)

The distance between the first 2 points is √(3² + 3²) = √18

The distance between point-2 and point-3 is √(4² + 4²) = √32

The distance between point-3 and point-4 is √(3² + 3²) = √18

The distance between point-4 and point-1 is √(4² + 4²) = √32 .

Notice that it wasn't really necessary to find all four distances.
As soon as I found the first two distances, I knew that one is the length
of the rectangle and the other one is the width of the rectangle, so I didn't
have to bother finding the other two, because I knew that they would be
the same as the first two. I just did it anyway, to make SURE that they
were the same. That helped me be sure that I didn't make any mistakes.

So here we are, outstanding in our field. (Actually, in Ms. Stone's field.)
We have a rectangle with a length of √32 units and a width of √18 units.

The area of any rectangle is (length) · (width)

   = (√32 units) · (√18 units)

   = √(32 · 18)    units²

   =   √ (576)    units²

   = 24 units² .

We also know that each square unit on the map indicates 16 acres.
So the actual area of the field is

(24 units²) · (16 acres/unit²) = 384 acres .

Ms. Stone sold the field for $858,240 .

The unit sale price was

($858,240) / (384 acres) = $2,235 / acre .

Ms. Stone can now move into the city and live the life of a rich lady.
