Answer:

6! = 720

Step-by-step explanation:

In evaluating factorial functions, generally

n! = n(n-1)(n-2)(n-3)...× 1

We can see that as we are moving, the value keep decreasing by 1 until it reaches the least value which is 1.

6! = 6(6-1)(6-2)(6-3(6-4)(6-5)

6! = 6×5×4×3×2×1

6! = 720

A circle is a special form of an ellipse, occurring when both focal points of an ellipse coincide at one point, making its eccentricity zero.

A special form of the ellipse is called a circle. This occurs when the two focal points of an ellipse coincide at a single point, which is also the center of the circle. In mathematical terms, an ellipse whose equation is scaled down in one direction, transforming it into x² + y² = a², represents a circle with center at the origin and radius a.

Kepler's first law regarding planetary orbits also refers to this special case of an ellipse. It states that planets follow an elliptical path with the Sun at one of its focal points. When both focal points are at the same location, indicative of zero eccentricity, the orbit is not elliptical but circular.

The properties of an ellipse are crucial in understanding celestial mechanics and orbits, reflecting the significance of this special case in both mathematics and astronomy.

Answer: 0.6x = 87

Step-by-step explanation:

Hi, to answer this question we have to write en equation:

We have to multiply the variable x by the percentage given (60%) in decimal form (divided by 100). That expression must be equal to 87.

Mathematically speaking:

x (60/100) = 87

0.6x = 87

Feel free to ask for more if needed or if you did not understand something.

This equation states that 60% (or 0.60) of x is equal to 87.

To express the relationship between 60% of x and 87, we can set up an equation. Since 60% can be written as 0.60, we can write:

0.60x = 87

To solve for x, we divide both sides of the equation by 0.60:

x = 87 ÷ 0.60

So, x will be:

x = 145

This shows that 60% of 145 is equal to 87.

Step-by-step explanation:

Area of square = 2 triangles

Find the area of the square using s²

For area of the triangle, divide by 2

The area of Jens square and the area of the triangle is A = ( 1/2 )s²

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of sides of the triangle are

AB = AC = s

From the figure , we can see that

Now , area of the triangle = ( 1/2 ) x Length x Base

On simplifying , we get

A = ( 1/2 )s²

Hence , the area of the triangle is A = ( 1/2 )s²

Step-by-step explanation:

The angles is a triangle add up to 180 so

70+45+∠BCX=180 so

115+∠BCX=180 (subtract 115 from both sides)

∠BCX=65

A line adds up to 180

so 2x+15+65=180

so 2x+80=180 (subtract 80 from both sides)

Step-by-step explanation:

The expression could represent the dog kennel is (x + 2)(x + 6)²

What expression could represent the dog kennel

From the question, we have the following parameters that can be used in our computation:

Volume = x³ + 14x² + 60x + 72

Height = x + 2

Dividing the Volume by the Height , we have

            x² + 12x+ 36

x + 2  |  x³ + 14x² + 60x + 72

            x³ + 2x²

--------------------------------------------------------

                       12x² + 60x + 72

                       12x² + 24x

--------------------------------------------------------

                       36x + 72

                       36x + 72

--------------------------------------------------------

                                  0

So, we have

x³ + 14x² + 60x + 72 = (x + 2)(x² + 12x+ 36)

Expand

x³ + 14x² + 60x + 72 = (x + 2)(x + 6)²

Hence, the expression could represent the dog kennel is (x + 2)(x + 6)²

[tex]36\pi -18\sqrt{7}[/tex]

Step-by-step explanation:

Every inscribed right triangle has its hypotenuse as the same size of the Diameter. Assuming that, this is the case check the picture below.

So the hypotenuse= D=2R=12

[tex]A_{circle}=\pi (6)^{2}=36\pi[/tex]

Finding the Triangle base via the Pythagorean Theorem

[tex]a^2=b^2+c^2\\12^2=9^2+c^2\\144-81=c^2\\c=\sqrt{63}\\c=3\sqrt{7}\approx 7.94[/tex]

There are 5 faces of a given polyhedron.

A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminate in mathematics. Majorly used polynomials are binomial and trinomial.

Euler's formula states that for a polyhedron with V vertices, E edges, and F faces,

V - E + F = 2.

In this case, we know that the polyhedron has 12 edges and 9 vertices. Let's use Euler's formula to solve for the number of faces:

9 - 12 + F = 2

F = 2 + 12 - 9

F = 5

Therefore, the polyhedron has 5 faces.

Answer:

352.48

Step-by-step explanation:

The volume of a cylinder with a base diameter of 8ft and height of 20ft is approximately 1005.3 cubic feet.

The volume of a cylinder can be calculated using the formula Volume = πr²h where π represents approximately the number 3.14, 'r' signifies the radius of the cylinder, and 'h' denotes the height of the cylinder.

In this case, the diameter of the cylinder is given as 8 feet, so the radius will be half of that which is 4 feet. The height is specified as 20 feet.

Substitute these values into the equation:

Volume = π * (4 ft)² * 20 ft

This simplifies to:

Volume = 3.14 * 16ft² * 20ft

By multiplying these values, we get the volume equals the product of these numbers:

Volume ≈ 1005.3 cubic ft. Hence, the volume of this cylinder to the nearest tenths is 1005.3 cubic feet.

https://brainly.in/question/51115062

SPJ3

The volume of a cylinder with an 8ft diameter and 20ft height is approximately 1005.3 cubic feet, rounded to the nearest tenths place.

To calculate the volume of a cylinder, we use the formula V = πr²h, where V represents the volume, r is the radius of the cylinder's base, and h is the height of the cylinder. Given that the diameter of the cylinder is 8ft, the radius is half of the diameter, which is 4ft. Now, using the formula:

V = πr²h

V = π(4ft)² × 20ft

V = π16ft² × 20ft

V = π 320ft³

V = 1005.31ft³

Therefore, the volume of the cylinder is approximately 1005.3 cubic feet, rounded to the nearest tenths place.

Answer:

-2

Step-by-step explanation:

The value of  f(6) for the function f(x) = 1/2 x - 5 will be -2.

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

In other terms, a function is a relationship between variables, and the type of relationship that exists between the variables defines the function, such as y = sinx and y = x +6.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

Given the function

f(x) = 1/2 x - 5

value of function at x = 6

f(6) = (1/2)6 - 5

f(6) = 3 - 5 = -2

Hence, value of function f(x) at x = 6 will be -2.

Final answer:

Each container will have approximately 3.75 kilograms of rice, which can be expressed as 3.75 kg or 15/4 kg.

Explanation:

To find out how many kilograms of rice are in each container, we need to divide the total weight of the rice by the number of containers. In this case, we have 15 kilograms of rice and 4 containers, so we divide 15 by 4. The result is 3.75 kilograms.

So, each container will have 3.75 kilograms of rice.

As a decimal, this can be expressed as 3.75 kg. As a fraction, it can be written as 15/4 kg.

Answer:

The third one is correct, the others bend the truth as they can touch but not overlap. As the third one states 'They are organized in equal intervals.'  this means they share an equal growth opportunity within their own column, their own height and nominated place within the histogram. The bars are of equal width and correspond to the equal class intervals. But on rare occasions like size classes they can be shown as a wider variant within their groups. Example would be showing a wider column say on classes at a school as the width and data being achieved forces a true event of variant sizes in education upon the base of the graph, this rarely applies to staff graphs as planning for schools is a wider data share than say offices using these types of graphs. Work development would use just data percentages along with the frequencies is one example so group size are stated in the reports to support more specific data in the graphs instead.

Step-by-step explanation:

To display numerical data that has been organized into equal intervals. The bars should touch the adjacent bars but not overlap. These intervals allow you to see the frequency distribution of the data, or how many pieces of data are in each interval.
