Final answer:
The expression −(1/4· 1/4· 1/4· 1/4) is written using exponents as −(1/4)⁴.
Explanation:
The expression −(1/4· 1/4· 1/4· 1/4) can be rewritten using exponents by recognizing that we are multiplying 1/4 by itself four times. Converting a repeated multiplication into exponential form means we use a base (which is 1/4 in this case) and an exponent (the number of times we multiply the base by itself). Thus, we write the expression as −(1/4)⁴. The negative sign just indicates that the result should be taken as the opposite (negative) value of (1/4)⁴.

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:

Eight 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.

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)
Can you conclude that this parallelogram is a rectangle? Explain.
To conclude if a parallelogram is a rectangle, we need to check if its opposite sides are congruent and if its angles are right angles.
Explanation:To determine if a parallelogram is a rectangle, we need to check if its opposite sides are congruent and if its angles are right angles.
In a rectangle, opposite sides are congruent and all angles are right angles (90 degrees).
So, if we can prove that the given parallelogram has congruent opposite sides and right angles, then we can conclude that it is a rectangle.
Alternatively, we can also look for other properties of rectangles such as diagonals being congruent or the presence of perpendicular bisectors.
A conclusion that be drawn based on the parallelogram include the following: C. No; the diagonals may not be congruent.
In Mathematics and Euclidean Geometry, a rectangle is a type of quadrilateral or polygon in which its opposite sides are equal and all the angles that are formed are right angles.
Generally speaking, the diagonals of a rectangle divide it into two equal parts and this implies that, the two diagonals of any rectangle are congruent.
In this scenario, we can logically deduce that this parallelogram is not a rectangle because its diagonals may not be congruent, as no congruence symbols were shown.

A cylinder has a radius of 10 cm and a height of 9 cm. A cone has a radius of 10 cm and a height of 9 cm. Show that the volume of a cylinder is three times the volume of the cone. someone help me out
Step-by-step explanation:
We start with the formulas for the volumes of a cylinder and a cone.
Cylinder:
[tex] V_{cylinder} = \pi r^2 h [/tex]
Cone:
[tex] V_{cone} = \dfrac{1}{3} \pi r^2 h [/tex]
Now we calculate the two volumes.
Cylinder:
[tex] V_{cylinder} = \pi r^2 h [/tex]
[tex] V_{cylinder} = \pi \times (10~cm)^2 \times 9~cm [/tex]
[tex] V_{cylinder} = \pi \times 100~cm^2 \times 9~cm [/tex]
[tex] V_{cylinder} = 900 \pi~cm^3 [/tex]
Cone:
[tex] V_{cone} = \dfrac{1}{3} \pi \times (10~cm)^2 \times 9~cm [/tex]
[tex] V_{cone} = \dfrac{1}{3} \pi \times 100~cm^2 \times 9~cm [/tex]
[tex] V_{cone} = 300 \pi~cm^3 [/tex]
The volume of the cylinder is 900pi cm^3, and the volume of the cone is 300pi cm^3.
Now we divide the volume of the cylinder by the volume of the cone.
[tex] \dfrac{900 \pi~cm^3}{300 \pi~cm^3} = 3 [/tex]
Dividing the volume of the cylinder by the volume of the cone gives us 3, showing that the volume of the cylinder is 3 times the volume of the cone.
The volume of a cylinder is three times the volume of a cone.
Explanation:To show that the volume of a cylinder is three times the volume of a cone, we need to compare their formulas. The volume of a cylinder is given by the formula V = πr²h, where r is the radius and h is the height. The volume of a cone is given by the formula V = (1/3)πr²h, where r is the radius and h is the height.
Let's calculate the volume of the cylinder first. Given that the radius (r) is 10 cm and the height (h) is 9 cm, we can substitute these values into the formula: V = π(10 cm)²(9 cm) = 900π cm³.
Now let's calculate the volume of the cone. Again, substituting the values for r and h, we have V = (1/3)π(10 cm)²(9 cm) = 300π cm³.
Comparing the volumes, we have 900π cm³ for the cylinder and 300π cm³ for the cone. Dividing the volume of the cylinder by the volume of the cone, we get (900π cm³) / (300π cm³) = 3. This shows that the volume of the cylinder is three times the volume of the cone

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.

Answer:
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.
When the following quadratic equation is written in standard form, what is the value of c?-3/4 x^2+2=0
When the quadratic equation is written in standard form the value of c is 8
To find the value of c when the quadratic equation -3/4 x² + 2 = 0 is written in standard form (ax² + bx + c = 0), follow these steps:
Move the constant term to the right side:
-3/4 x² = -2
Multiply both sides by -4/3 to get the standard form:
4x² = 8
Identify the coefficient of x² (a) and the constant term (c):
In this case, a = 4 and c = 8.
Therefore, when the equation is written in standard form, c = 8.

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.
