Answer:
Diagram A
Step-by-step explanation:
Diagram A shows the ''converging lines.''
What is Line segment?
Line segment is a part of the line which have two endpoints and bounded by two distinct end points and contain every point on the line which is between its endpoint.
Given that;
The diagram is shown in figure.
Now,
We know that;
Two or more lines that get closer and closer towards the end are called the Converging lines.
Thus, Diagram A shows the ''converging lines.''
Therefore, Diagram A shows the ''converging lines.''

8. The logo for a company is a regular hexagon inscribed inside a circle. The logo will
be painted on the side of the company's office building. The radius of the circle will be
8 ft. Find the area of the hexagon to the nearest whole foot.
Divide the hexagon into 6 equal streak triangles which would have side length equal to the radius of the circle.
the area of an equal lateral triangle = sqrt(3)/4 x radius^2
the area of the hexagon would be 6 x sqrt(3)/4 x radius^2
Area = 6 x sqrt(3)/4 x 8^2 = 166.2768 square feet
rounded to the nearest whole foot = 166 square feet.

What is the linear system?It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Two less than the quotient of a number and four, increased by ten.
That can be written as in the form of m will be
[tex]\rm 2 - \dfrac{m}{4} + 10[/tex]
If the value of m is 12, then we have

Answer:
x 8 -5
9 72 -45
-6 -48 30
Step-by-step explanation:
We have to complete the multiplication grid, where each cell is the result of multiplying the column lable by the row label.
For the blank in the first column, we have to multiply:
8×(-6)=-48
We now have to find the column label for the second column.
If we call this label x, we know that -6 times x is equal to 30.
Then, we can find x as:
(-6)×x=30
[tex]x=\frac{30}{-6}[/tex]
x=-5
Then, we can complete the first row by multiplying -5 times 9:
-5×9=-45
Then, the table becomes:
x 8 -5
9 72 -45
-6 -48 30

What is the missing number? Find the missing number
Answer:
1/4
Step-by-step explanation:
Dividing a number by something is the same thing as multiplying it by the reciprocal. To find the reciprocal, you flip the number.
In this case, you are dividing 83 by 4. The reciprocal of 4 is 1/4. So the missing number is 1/4.

pls tell me if im wrong
can someone tell me if these is Linear or Quadratic
Answer:
both are Quadratic
Step-by-step explanation:
To determine if a table of function values represents a linear function or a quadratic function, you can often look at first- and second-differences of the dependent variable.
The x-values are evenly spaced in each case, so the question can be answered by looking at differences in y-values. The set of first differences is the result of subtracting a given column from the next. The set of second differences is found by doing the same, using the first differences.
Table 1First differences; 21 -11 = 10, 35 -21 = 14, 53 -35 = 18, 75 -53 = 22
Second differences: 14 -10 = 4, 18 -14 = 4, 22 -18 = 4
The second differences all have the same value: 4. That means the function is 2nd degree, quadratic.
__
Table 2First differences: 10 -12 = -2, 9 -10 = -1, 9 -9 = 0, 10 -9 = 1
Second differences: -1 -(-2) = 1, 0 -(-1) = 1, 1 -0 = 1
The second differences all have the same value: 1. That means the function is 2nd degree, quadratic.
__
Additional comment
The level at which differences are the same tells you the degree of the polynomial that will match the given function points. If first differences are constant, then the function is 1st degree: linear. Here, second differences are constant, so the functions are 2nd degree: quadratic. If you have to go to 4th differences to get constant values, then the table will require a 4th-degree polynomial to match its values. This presumes the x-values are all evenly-spaced.
If the x-values are not evenly spaced, then determining the degree of the function can be done by graphing and/or using regression formulas. Various interpolation polynomials are available for matching the points exactly.
Cindy is baking a 2-layer cake. The top layer has a diameter of 8 inches and the bottom layer has a diameter of 10 inches. What is the difference in area between the top
surfaces of the two cakes?
Answer:
28.72
Step-by-step explanation:
The area for the 8 inch diameter cake is 50.27
1/4·π·8^2
but the area for the 10 inch diameter cake is 78.54
1/4·π·10^2 = 78.54
All you do to find the difference is

Type the correct answer in the box. Express your answer to three significant figures. An air mattress is filled with 0. 55 moles of air. The air inside the mattress has a temperature of 295 K and an absolute pressure of 3. 5 kilopascals. What is the volume of the air mattress? The volume of the air mattress is liters.
The volume of the air mattress in liters is 385.43 liters approx.
What is ideal gas law?For an ideal gas(or a gas that behaves sufficiently like an ideal gas), we have the following relation:
[tex]\rm PV = nRT[/tex]
where, the symbol denotes:
P = Pressure of the gasV = volume of the gasT = temperature of the gasn = count of moles of the gasR = universal gas constant = 8314.46261815324 [tex]L.Pa.K^{-1}.mol^{-1}[/tex]For the given case, the gas in the air mattress has following properties:
P = 3.5 kilopascals =3500 pascals
T =295 K
n = 0.55 moles
V = volume of gas in air mattress = volume of mattress (to evaluate).
Thus, using the ideal gas law, we get:
[tex]V = \dfrac{nRT}{P} = \dfrac{0.55 \times 8314.46261815324 \times 295}{3500} \approx 385.43 \: \rm liters[/tex]
Thus, the volume of the air mattress in liters is 385.43 liters approx.

Beatriz went on a road trip. By the end of the first day, she was 200\text{ km}200 km200, end text from the starting point of her trip, in a direction that is a °300, degree rotation from east. By the end of the second day, she was 150\text{ km}150 km150, start text, space, k, m, end text from where she was at the beginning of that day, in a direction that is a 250\degree250°250, degree rotation from east. What is Beatriz's direction, relative to the starting point of her trip, by the end of the second day?
The direction of Beatriz relative to the starting point of her trip is approximately [tex]278.806^{\circ}[/tex].
How to find the position of Beatriz relative to the starting point of her tripAfter a careful reading of the statement, we find that final position ([tex]\vec r[/tex]) by the end of the second day is found by means of this vector sum:
[tex]\vec r = \vec r_{1} + \vec r_{2}[/tex] (1)
Where:
[tex]\vec r_{1}[/tex] - Vector distance of the first day relative to starting point, in kilometers. [tex]\vec r_{2}[/tex] - Vector distance of the second day relative to the final point of [tex]\vec r_{1}[/tex], in kilometers.If we know that [tex]\vec r_{1} = (200\,km \cdot \cos 300^{\circ}, 200\,km\cdot \sin 300^{\circ})[/tex] and [tex]\vec r_{2} = (150\,km\cdot \cos 250^{\circ}, 150\,km\cdot \sin 250^{\circ})[/tex], then final position of Beatriz relative to origin is:
[tex]\vec r = (200\,km\cdot \cos 300^{\circ}, 200\,km\cdot \sin 300^{\circ})+(150\,km \cdot \cos 250^{\circ}, 150\,km\cdot \sin 250^{\circ})[/tex]
[tex]\vec r = (48.670, -314.159)\,[km][/tex]
And the direction relative to the starting point ([tex]\theta[/tex]), in degrees, is found by following inverse trigonometric relation:
[tex]\theta = \tan^{-1} \frac{r_{y}}{r_{x}}[/tex] (2)
If we know that [tex]r_{x} = 48.670\,km[/tex] and [tex]r_{y} = -314.159\,km[/tex], then the direction of Beatriz relative to the starting point of her trip is:
[tex]\theta = \tan^{-1} \left(\frac{-314.159\,km}{48.670\,km} \right)[/tex]
[tex]\theta \approx 278.806^{\circ}[/tex]
The direction of Beatriz relative to the starting point of her trip is approximately [tex]278.806^{\circ}[/tex]. [tex]\blacksquare[/tex]

Answer:
A. x = -7, B. x = -8, C. x = 9, D. x = 2, E. x = -3
Step-by-step explanation:
A. 4x= -28
Divide both sides by 4.
[tex]\frac{4x}{4\\}[/tex]=[tex]\frac{-28}{4}[/tex]. x= -7
B. x- -6= -2 -> x+6= -2
Subtraction 6 to both sides.
x- +6-6= -2-6, x= -8
C. -x+= -9 -> x= 9
D. -3x+7=1
Subtraction 7 to both sides.
-3x+7-7 =1-7 , -3x=-6
Divide both sides by -3.
[tex]\frac{-3x}{-3}[/tex] = [tex]\frac{-6}{-3}[/tex], x= 2
E. 25x+-11= -86 -> 25x-11= -86
Add 11 to both sides.
25x-11+11= -86+11, 25x= -75
Divide both sides by 25.
[tex]\frac{25x}{25}[/tex] = [tex]\frac{-75}{25}[/tex], x= -3
2. 2x+9= -15
Subtraction 9 to both sides.
2x+9-9= -15-9, 2x= -24
Divide both sides by 2.
[tex]\frac{2x}{2}[/tex] = [tex]\frac{24}{2}[/tex] , x= 12
