Answer: A. Line segment
Step-by-step explanation:
A line is a one-dimensional geometric straight -undefined figure which has no thickness or depth . It extends infinitely in both directions.
A line segment is a part of a line having end-points on both the sides.
It has only length therefore, it is one dimensional.
Thus , the objects is considered to be one-dimensional because it has length but no width or height is a line segment.
The triangle is 2-dimensional , point has no-dimensions, and cube is 3-dimensional.
A line segment is the correct answer, as in mathematics it is considered one-dimensional because it only has length but no width or height. It extends in one direction, unlike a triangle and a cube, which have more dimensions. The point does not have length.
Explanation:In mathematics, a line segment is considered to be one-dimensional as it only possesses a property of length but no width or height. This means it only extends in one direction, often represented on a number line. In comparison, other options presented such as a triangle, point or cube have other dimensions involved. Specifically, a triangle falls in two dimensions as it has both length and width; a cube is a three-dimensional object possessing length, width, and height; and a point, though it lacks all three dimensions, is not accurate as it doesn't have length, which is the key criterion in the question.

In two or more complete sentences, explain how to solve the cube root equation, .^3√x-1+2=0
Answer:
[tex]x= -7[/tex]
Step-by-step explanation:
We need to solve the following root equation:
[tex]\sqrt[3]{x-1} + 2 = 0[/tex]
1. First, we need to add minus two to both sides of the equation:
[tex]\sqrt[3]{x-1}= -2[/tex]
2. Elevate each side of the equation to the power of 3:

Given: m∠AOC = 120°, m∠BOD = 150°. Find: m∠FOE.
In the finding of m<FOE, I think it would be 70°.
Answer:
∠FOE = 90°
Step-by-step explanation:
In this question given is m∠AOC = 120°, m∠BOD = 150°.
We have to calculate ∠FOE.
Since ∠AOB + ∠COD + ∠BOC = 180° [ Angle at a point on a straight line ]
∠AOB + ∠COD = 180° - ∠BOC ---(1)
It is given ∠AOC = 120° = ∠AOB + ∠BOC -----(2)
and ∠BOD = 150° = ∠BOC + ∠COD ------(3)
By adding equation (2) and (3)
150 + 120 = ∠ BOC + ∠COD + ∠AOB + BOC
270 = 2∠BOC + ∠COD + ∠ AOB
Now from equation (1)
270 = 2∠BOC + (180 - ∠BOC)
270 = 180 + ∠BOC
270 -180 = ∠BOC
∠BOC = 90°
Since ∠ BOC ≅ ∠FOE (opposite angles)
Therefore, ∠FOE = 90° is the answer.
Use only the digits 0 - 9 and the decimal and the negative sign, if needed, to fill in the blank. If f(x) = 2x + 9, then f(-1) =
Answer:
7
Step-by-step explanation:
Replace both instances of x in f(x) = 2x + 9 with -1:
f(-1) = 2(-1) + 9 = 7
Thus, f(-1) = 7
The value of the function f(x) = 2x + 9 at x = - 1 Or f(-1) is 7.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, A function f(x) = 2x + 9.
We know, Substitution in mathematics is when we replace some specific numerical values to variables according to our wants or given in the problem.
Therefore, f(-1) = 2(-1) + 9.
f(-1) = - 2 + 9.
f(-1) = 7.

What is the vertex of the quadratic function f(x)=(x-6)(x+2)
Answer:
vertex = (2, - 16)
Step-by-step explanation:
given
f(x) = (x - 6)(x + 2) ← equate to zero to find the zeros
(x - 6)(x + 2) = 0
Equate each factor to zero and solve for x
x - 6 = 0 ⇒ x = 6
x + 2 = 0 ⇒ x = - 2
The vertex lies on the axis of symmetry which is situated at the midpoint of the zeros, hence
[tex]x_{vertex}[/tex] = [tex]\frac{6-2}{2}[/tex] = [tex]\frac{4}{2}[/tex] = 2
Substitute x = 2 into f(x) for corresponding y- coordinate of vertex
f(2) = (2 - 6)(2 + 2) = - 4 × 4 = - 16
vertex = (2, - 16)

294.36
Step-by-step explanation:
Find the area of the entire circle.
Subtract out the area of a sector with 130 degrees for the central angle.
Add the area of the isosceles triangle with an apex angle of 130 degrees.
Area of The entire circle
Area = pi * r^2
Area = 3.14 * 11.1^2
Area = 386.88 m^2
Area of the sector with 130 degrees for a central angle
Area_130 = (130/360) * pi * r^2
Area_130 = (130/360) * 3.14* 11.1^2
Area_130 = 139.71
Area of the triangle
1/2 central angle = 130/2 = 65
Bisect the apex angle so that each half = 65 degrees.
Sin(65) = opposite / hypotenuse
Sin(65) = Opposite / 11.1
11.1 * sin(65) = opposite
opposite = 10.06
This is 1/2 the base so the base = 2*10.06 = 20.12
The height of the triangle is found by cos(65) = adjacent/hypotenuse
hypotenuse = 11.1
Cos(65) = adjacent / hypotenuse
adjacent = hypotenuse * cos(65)
adjacent = 4.69 This is the height of the triangle.
Area of the triangle = 1/2 * 20.12 * 4.69
Area of the triangle = 47.19 m^2
Area of the Shaded Area
Area of entire circle - area of sector + area of triangle
=386.88 - 139.71 + 47.19
=294.36
Note
The area of the triangle could be done using Area = 1/2 * 11.1^2 * (2*sin(65)*cos(65) = 1/2 * 11.1^2 * sin(130) = 47.2 but you may not know all the math to do the area this way.
Find the quartiles for these data values of 5, 7, 7, 8, 10, 11, 12, 15, 17
The median {Q2} is 10
Q1 is 7+7/2 which is 7
Q3 is 15+12/2 which is 13.5
Final answer:
The quartiles for the data set (5, 7, 7, 8, 10, 11, 12, 15, 17) are found by arranging the data in order and then finding the medians of the lower and upper halves. The first quartile (Q1) is 7, the median (Q2) is 10, and the third quartile (Q3) is 13.5.
Explanation:
To find the quartiles for the data set (5, 7, 7, 8, 10, 11, 12, 15, 17), you first arrange the data in ascending order, which is already done. The median (Q2) is the middle value when the data set is in order, so since there are 9 data points, the median is the fifth value, which is 10.
The first quartile (Q1) is the median of the lower half of the data. For our data set, the lower half is (5, 7, 7, 8), so the median of this set is the average of the middle two values because we have an even number of data points in the lower half. Thus, Q1 is (7 + 7)/2 = 7.
The third quartile (Q3) is the median of the upper half of the data. For our dataset, the upper half is (11, 12, 15, 17). Similarly, since this is an even set, Q3 is the average of the middle two values, (12 + 15)/2 = 13.5.
Therefore, the quartiles for this data set are:
First quartile (Q1): 7Median (Q2): 10Third quartile (Q3): 13.5Eight travelers sleeping in a hostel are snoring The hostel has 15 sleeping travelers. How many travelers are not snoring?
Answer:7
Step-by-step explanation:
There are 15 sleeping and only 8 snoring you subtract 8 from 15 which leave you with 7 and that's how many people
By subtracting the number of travelers snoring (8) from the total number of travelers (15), we determine that there are 7 travelers not snoring.
To find out how many travelers in the hostel are not snoring, we will subtract the number of travelers who are snoring from the total number of travelers. The problem states that 8 travelers are snoring, and there are 15 travelers in total. So, we perform the following calculation:
Total travelers - Travelers snoring = Travelers not snoring
15 - 8 = 7
Thus, there are 7 travelers who are not snoring.
