The population of the city after eight years is 35,125,731,743

Population growth is the increase in the number of people in a population or dispersed group. The expression P(t) = P(o)(1+r)^t can be used to determine the growth rate of a population.

Where P(t) is the population at a particular time

P(o) is the initial population , t is the time and r is the growth rate.

Here the growth rate has been given, but we are to find p(t).

P(t) = 330,000(1+3.25)⁸

P(t) = 330,000(4.25)⁸

P(t) = 330,000× 106441.61

P(t) = 35,125,731,743( nearest billion)

Therefore the population of the city after 8years is 35,125,731,743

The Equation of the Line in Standard form is 4x - y = 3

What is Slope of a Line?

The slope formula is used to compute the inclination or steepness of a line. The slope of the lines is calculated using the x and y coordinates of the lines. It is the ratio of the y-axis change to the x-axis change.

Solution:

Slope of the Line passing through the points (1, 1), (2, 5)

is

m = 5-1/2-1 = 4

Equation of the line = (y - y1) = m(x - x1)

y - 1 = 4(x - 1)

y - 1 = 4x - 4

The stated statement indicates that the takt time is 5.38 minutes for each section.

Takt time is calculated as the amount of manufacturing time that is available divided by the volume of orders. Takt time, for instance, is two minutes if a factory makes widgets for 480 minutes a day and clients need 240 widgets per day. Similar to this, the takt time is one week if clients desire two new goods per month.

Takt time depends on client demand and the amount of time that is available, and for many items, it is always changing as the demand from the market shifts. Takt time is unaffected by system changes, although cycle time is affected.

Available hours are 7 * 60 minutes, which is 420 minutes.

No. of parts = 78 units

Available time for work / No of parts = Takt time

               = 420/ 78

               = 5.38 minutes per part

Step-by-step explanation:

your question is strange.

first you tell us that 50 people like coffee, 25 like tea, and 13 like both.

and then you ask how many like coffee or tea or both.

is this a joke ? or do you rather mean how many like only coffee, or only tea, and how many don't like neither ?

since 13 people like coffee and tea, these 13 are also part of the group of 50 that like coffee, and of the group of 25 that like tea.

so, to get the number of people that like only one, we need to deduct the number of people, who like both from both groups.

the number of people that only like coffee is therefore

50 - 13 = 37

and the number of people that only like tea is

25 - 13 = 12

we know the number of people that like coffee and tea is 13.

together that are

37 + 12 + 13 = 62 people.

that means 70 - 62 = 8 people don't like neither coffee nor tea.

Answer: 62

Step-by-step explanation:

Those who like coffee only = 50 - 13 = 37. Those who like tea only = 25 - 13 = 12. Those who like either coffee, or tea, or both = 37 + 12 + 13 = 62.

In theory, the 70 people being surveyed could fall under any of the following four categories:

I have labelled the four categories 1, 2, 3 and 4 for convenient reference.

From the information provided in the question, category 1 contains 50 people, category 2 contains 25 people, while category 3 contains 13 people. We do not yet know how many people fall under category 4, but we shall calculate it.

We know from set theory that the four aforementioned categories are known formally as sets. A set is simply a group of objects or things that are similar in some way. Each of the objects in a set is called a member of that set. Two sets can intersect. The intersection of two sets is simply the collection of members that are in both of the two sets. Also, two sets can unite. The union of two sets is the collection of members that in either of the two sets.

For example, category 3 is the intersection of category 1 and 2. The question requires us to calculate the union of category 1 and 2.

The required values of x and y are x = 2 and y = 11.

We have been given that parallelogram PQRS which has:

PT = ​y, TR = 5x+​1, QT = 2​y, TS = 6x+10

We know that the diagonals of a parallelogram bisect each other.

So, PT = TR and QT = TS

Substitute the values and we have a system of equations:

y = 5x + ​1    ....(i)

2y = 6x + 10 ....(ii)

Substitute the value of the equation y = 5x + ​1 in equation (ii), and solve for x

2(5x + ​1) = 6x + 10

10x + 2 = 6x + 10

10x - 6x = 10 - 2

4x = 8

x = 8/4

x = 2

Substitute the value of x = 2 in equation (i), and solve for y

y = 5(2) + ​1

y = 10 + 1

y = 11

Therefore, the required values of x and y are x = 2 and y = 11.

What is system of equations?

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, also known as a system of equations or an equation system.

Let

Price of shirts = x

Price of slacks = y

Price of sports = z

From the given information,

3x + y = $13.46         ..(1)

7x + 3y + z = $43.39         ..(2)

5x + 2z = $28.43        ..(3)

From equation (1), y = 13.46 - 3x

From equation (3),  z = (28.43 - 5x) / 2

Plug the value of x and z in equation (2)

7x + 3(13.46 - 3x) +(28.43 - 5x)/2 = 43.39

7x + 40.38 - 9x + 14.22 - 2.5x = 43.39

-4.5x +54.6 = 43.39

4.5x = 54.6 - 43.39

4.5x = 11.21

x = 2.49

Plug x = 2.49 in equation (1)

3(2.49) + y = 13.46

2.47 + y = 13.46

y = 5.99

Plug x = 2.49 in equation (3),

5(2.49) + 2z = 28.43

12.45 + 2z = 28.43

2z = 15.98

z = 7.99

To evaluate the integral, you will need to define the limits of integration and use appropriate coordinate systems for the given area.

And the area is given as   [tex]I_{xy} =\int \limits \int \limits {(y^2 - x^2)} \,dm[/tex]

What is direct integration?

Direct integration is a method of finding the moment of inertia of a body or a region about a given axis by directly integrating the product of the mass of each infinitesimal element of the body or region and the square of its distance from the axis.

To determine the product of inertia of a given area with respect to the x and y axes, you will need to first define the area and its mass distribution. Then, you can use the following formula for the product of inertia:

[tex]I_{xy} =\int \limits \int \limits {(y^2 - x^2)} \,dm[/tex]

Where Ixy is the product of inertia, y is the distance from the y-axis, x is the distance from the x-axis, and dm is the mass of an infinitesimal element of the area.

Answer:

Slope is undefined. { Infinity }

Step-by-step explanation:

Formula we use,

→ Slope(m) = (y2 - y1)/(x2 - x1)

Now required slope will be,

→ m = (y2 - y1)/(x2 - x1)

→ m = (8 + 12)/(17 - 17)

→ m = 20/0

→ [ m = 0 ]

Hence, the slope is undefined.

The slope of the line passing through the points ( 17 , -12 ) and ( 17 , 8 ) is undefined

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P ( 17 , -12 )

Let the second point be Q ( 17 , 8 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 8 - ( -12 ) ) / ( 17 - 17 )

On simplifying the equation , we get

Slope m = ( 8 + 12 ) / 0

Slope m = 20 / 0

So , the slope is undefined

Hence , the slope of the line is m = undefined

The sum of the angles in a triangle is 180 degrees.

One triangle is an equilateral triangle.

All three angles are equal.
