What is permutation and combination?A permutation is an act of arranging objects or numbers in order. Combinations are the way of selecting objects or numbers from a group of objects or collections, in such a way that the order of the objects does not matter.
For this, the easiest way is doing the complement. Calculate how many the 2 people are together and subtract from the total, so:
We can consider 2 people a block that will permutation, so, instead of 6 people we have 5 [a block of 2 people and 4 more):
5! = 5.4.3.2.1 = 120
The 2 people from the block will permutation as well:
2! = 2.1 = 2
Total: 5!.2! = 120.2 = 240.
For the case they are not following each other:
720 - 240 = 480

The maximum volume of the cylinder is 27147.355 cm² at the maximum point.
What is volume of cylinder?
The density of a cylinder is determined by its volume, which represents how much material may be immersed in it or carried inside of it. The formula r2h, where r is the radius of the circular base and h is the height of the cylinder, determines the volume of a cylinder. The substance could be a liquid amount or something else that can be evenly put into the cylinder.
The formula for the volume of the cylinder v = [tex]\pi r^2[/tex]h,
To find the maximum volume of the cylinder we apply the condition of maxima [tex]\frac{dv}{dr}[/tex] = 0.
Let r cm be the radius and h cm be the height of the closed cylinder.
Then, Total surface area of the cylinder = [tex]2\pi r(r+h)[/tex]
5000 = [tex]2\pi r^{2} +2\pi rh[/tex]
h = [tex]\frac{5000-2\pi r^{2} }{2\pi rh}[/tex]............(1)
Volume of the cylinder v = [tex]\pi r^2h[/tex]
Substitute the value of h in the above equation
= [tex]\pi r^2[/tex] × [tex]\frac{5000-2\pi r^{2} }{2\pi rh}\\[/tex]
= [tex]\frac{r}{2}[/tex] × [tex]5000-2\pi r^2[/tex]
v = [tex]2500r-\pi x^{3}[/tex] ..............(2)
Now, for the maximum volume of the cylinder dv/dr= 0
[tex]\frac{d(2500r-\pi x^{3})}{dr}[/tex] =0
[tex]3\pi r^{2} =2500[/tex]
[tex]r^{2} =\frac{2500}{3\pi }[/tex]
r=[tex]\frac{50}{\sqrt{3\pi } }[/tex]
r= 27147.355
Hence, The maximum volume of the cylinder is 27147.355 at the maximum point r= [tex]\frac{50}{\sqrt{3\pi } }[/tex].

What is derivative?
Differentiation refers to the method of determining the derivative. Anti-differentiation is the term for the opposite process. We'll calculate the derivative of the function y = f. (x). It represents the rate at which the value of y varies in relation to the change in the variable x. It is referred to as the "f" derivative with regard to the variable x.
Here the given expression is [tex]x^2y^2=10[/tex] then
=> f(x,y) = [tex]x^2y^2-10[/tex]
To find [tex]\frac{dy}{dx}[/tex] by using the formula [tex]\frac{dy}dx}=-\frac{f_x}{f_y}[/tex] and first find [tex]f_x , f_y[/tex]
Now ,
=> [tex]f_x =\frac{d}{dx}x^2y^2-10[/tex]
=> [tex]f_x=2xy^2[/tex]
Now,
=> [tex]f_y=\frac{d}{dy}x^2y^2-10[/tex]
=> [tex]f_y=2x^2y[/tex]
Now substitute into formula then
=> [tex]y' = -\frac{2xy^2}{2x^2y}[/tex]
=> y' = [tex]-\frac{-y}{x}[/tex]
Hence the derivative of the expression is y' = [tex]-\frac{-y}{x}[/tex].

the volume of the solid under the surface z = 9x + 5y² and above the region bounded by x = y² and x = y³ is: 89/210
What is volume of solid?Solid, liquid, and gas are the three different states of matter. Solids have a distinct volume and form. Although they have a specific capacity, liquids adopt the form of the container. Gases lack a distinct volume or form. Solids do not adapt to the shape of the container in which they are stored since they have a distinct shape, as well as mass and volume. In addition to having a high density, solids also feature closely packed particles. The volume of space that what a solid covers is assessed by its volume. It is calculated using the volume of unit cubes required to completely fill the solid.
Firstly, we will find bounds:
given that,
x = y²
x = y³
so, y² = y³
thus, y = 0, y = 1
now, we can set up integral for volume:
V= [tex]\int\limits^1_0 {x} \, dx \int\limits^{y_{2}}_{y_{3}} {9x + 5y^2} \, dx[/tex]
Firstly, we will solve innermost integral:
V = [tex]\int\limits^{y_{2}}_{y_{3}} {9x + 5y^2} \, dx[/tex]
V = [tex]\int\limits^{y_{2}}_{y_{3}} {5y^2} \, dx + \int\limits^{y_{2}}_{y_{3}} {9x } \, dx[/tex]
V = 5y⁴ - 5y⁵ + 9 (y⁴/2 - y⁶/2)
V = -9/2 y⁶ - 5y⁵ + 19y⁴/2
now, we can find outermost integral:
= [tex]\int\limits^1_0 {-9/2y^6 - 5y^5 + 19y^4/2} \, dx[/tex]
= -9/14 - 5/6 + 19/10
= 89/210

The price of a box of cereal under the price leadership model is 16 dollars.
The price of a box of cereal under the price leadership model can be calculated by finding the intersection of the marginal cost curve (MC) of the dominant firm and the marginal revenue curve (MR) of the dominant firm. The MR curve has twice the slope of the demand curve, so the equation for the MR curve is MR = 24 – 2Q, where Q is the quantity of boxes of cereal. The MC curve is horizontal, so the equation for the MC curve is MC = 12. The intersection of the two curves occurs at the quantity Q = 8 million boxes of cereal per year, and the corresponding price is P = 16 dollars per box of cereal.

Find the solution to the differential equation dy/dt=y2(6+t), y=8 when t=1 .
The solution of the differential equation is [tex]y = (48/t - 6t)^{-1/2}.[/tex]
A differential equation is a mathematical equation that describes the relationship between a function and its derivatives.
In this particular differential equation, the dependent variable is y and the independent variable is t. The equation states that the rate of change of y with respect to t is equal to
=> y²(6 + t).
To find the solution to this differential equation, we first need to separate the variables and integrate both sides.
This gives us an equation of the form
[tex]= > y = (C/t - 6t)^{-1/2}[/tex]
where C is an arbitrary constant.
To find the value of C, we use the initial condition y = 8 when t = 1. Plugging in these values, we find that
=> C = (8)² * 1 - 6 = 48.
So, the solution to the differential equation is
=> [tex]y = (48/t - 6t)^{-1/2}.[/tex]

Which equation is equivalent to 12 3/x + 15 = 36?
O 3x + 15 = 3
O x + 15 = 9
O x + 15 = -6
O 3/x+ 15 = 24
The correct answer is option 4. The equation that is equivalent to 12 3/x + 15 = 36 is 3/x + 15 = 24.
To isolate x in the equation, we need to subtract 15 from both sides, which gives us 3/x = 9. Then, we need to multiply both sides by x, which gives us 3 = 9x. Finally, we divide both sides by 9 to get x = 1/3. This means that the value of x that makes the equation true is 1/3. To verify, we can plug this value back into the original equation and see if both sides are equal.

Answer:
32 r26
Step-by-step explanation
First, you ask yourself if 27 can go into 8 and well it can't because 8 is smaller than 27 so you do 27 can go into 89! It can go into 89, 3 times.
27x3 is 81. 89-81 is 8 you bring down the 0.
27 can go into 80 which is 2 times. 27x2 is 54 and doesn't go over.
80-54 is 26. 27 can't go into 26 so your remainder is 26.

at which points is the tangent line to the curve 8x^2
By exploring the behavior of the tangent line at different intervals, the shape and behavior of the curve 8x², the slope is 16.
The tangent line to a curve is a straight line that just touches the curve at a single point, without crossing over it. The slope of the tangent line at that point is equal to the rate of change of the curve's slope at that point.
In the case of the curve 8x², we can find the tangent line at different points by using calculus. Calculus provides us with tools to find the slope of the curve, and from that, the equation of the tangent line.
So, to find the tangent line at a point on the curve
=> 8x²,
we need to find the derivative of the curve and evaluate it at the point of interest.
The derivative of
=> 8x² = 16x,
so the slope of the tangent line at any given point x is 16x.
To find the equation of the tangent line, we also need to know the y-coordinate of the point where the line touches the curve.
We can use this information to write the equation of the tangent line in the form y = mx + b, where m is the slope and b is the y-intercept.
Then the value of slope is 16.

The 11th term of an arithmetic sequence is 57 and the sum of the first and fourth terms is 29. A) Determine the first three terms of the sequence
Answer:
Step-by-step explanation:
Let's call the common difference of the arithmetic sequence "d", and the first term of the sequence "a". Then we can write two equations based on the information given:
a + 3d = 57 (the 11th term is 57)
a + a + 3d = 29 (the sum of the first and fourth terms is 29)
Solving for the first equation for "a", we get:
a = 57 - 3d
Substituting this expression for "a" into the second equation, we get:
57 - 3d + 3d = 29
57 = 29
So the first three terms of the arithmetic sequence are:
a = 57 - 3d
a + d = 57 - 2d
a + 2d = 57 - d
Solving for "d", we can find the value of "a", and then use the equations above to find the first three terms of the sequence

There exists two opposite sets of angles ( antipodal angles are equal).
What is meant by antipodal angles?The diametrically opposed points on a sphere are known as antipodal points in mathematics (the specific qualities of such a definition are that a line drawn from the one to the other passes through the center of the sphere so forms a true diameter).
If two separate points on a sphere lie along the same line passing through the center of the sphere, they are said to be diametrically opposed points. Antipodal points on the sphere are also known as diametrically opposed points.
We may determine from the image that the two triangles above are isosceles triangles ( the bottom angles one equal).
There are two sets of opposite angles ( antipodal angles are equal).
Let the equation be
[tex]$x & =180^{\circ}-\left(\frac{180^{\circ}-a}{2}+b\right) \\[/tex]
substitute the values in the above equation, we get
[tex]$& =180^{\circ}-\left(\frac{180^{\circ}-62^{\circ}}{2}+63^{\circ}\right) \\[/tex]
simplifying the equation, then
[tex]& =180^{\circ}-\left(59^{\circ}+63^{\circ}\right) \\[/tex]

The value of x in the following triangles is 59 degrees.
What is the sum of interior angles of triangle?One of the fundamental shapes in geometry is the triangle. The smallest polygon is a triangle. It has three vertices and three edges. The symbol for a triangle having the vertices P, Q, and R is PQR. The three sides and three angles that make up a triangle are referred to as its elements. The two crucial properties of a triangle are the external angle property and the angle sum property.
Given that,
a = 62 degree and
b = 62 degrees.
From the given figure we see that the two sides containing angle a are equal.
Thus, the value of the two angles containing angle a is:
a + x + x = 180
a + 2x = 180
62 + 2x = 180
2x = 180 - 62
2x = 118
x = 59
The value of x is 59. The angle x and the exterior angle of x form a straight line.
Thus,
x + y = 180
59 + y = 180
y = 121
The sum of angle y and the interior angle of triangle containing angle x is 180:
y + z = 180
121 + z = 180
z = 59
Now, for triangle containing angle b, the two sides are equal hence the angle corresponding to the side is b = 62.
The angle b and its exterior angle form a straight line. Thus,
b + c = 180
62 + c = 180
c = 118
The angle c and one interior angle of triangle form a straight line thus,
c + d = 180
118 + d = 180
d = 62
Now, the angles of the triangle containing angle x is:
z = 59 and d = 62
The sum of all the sides of triangle is 180, thus:
x + z + d = 180
x + 59 + 62 = 180
x = 59
Hence, the value of x is 59.

define a fruitful function to calculate the area of a triangle. the formula is:area of triangle = base * height /2
A function to define the area of the triangle is A(b,h) = (1/2)*b*h
A function is a process or a relation that associates each element 'a' of a non-empty set A , at least to a single element 'b' of another non-empty set B. A relation f from a set A (the domain of the function) to another set B (the co-domain of the function) is called a function in math. f = {(a,b)| for all a ∈ A, b ∈ B}.
1) A relation is said to be a function if every element of set A has one and only one image in set B.
2) A function is a relation from a non-empty set B such that the domain of a function is A and no two distinct ordered pairs in f have the same first element.
A function from A → B and (a,b) ∈ f, then f(a) = b, where 'b' is the image of 'a' under 'f' and 'a' is the preimage of 'b' under 'f'.
If there exists a function f: A → B, the set A is called the domain of the function f, and the set B is called its co-domain.
Let us assume that the base of the triangle is b and the height of the triangle is h.
So, a function to define the area of the triangle is
A(b,h) = (1/2)*b*h
This function is a function in two variables.
Thus, a function to define the area of the triangle is A(b,h) = (1/2)*b*h
