how many sides does a polygon have

One day when i had to solve some physics problem, i looking for a site which gives help with physics, came across many such sites. I was only aware of the math help online but had never heard of physics help ever before.

My teacher had given us a problem and asked us to solve this problem in the school in front of the class, and i was very much worried about this because i did not know the concept at all. I was worried and deep in my thoughts thinking of some plan for not attending school on the following day. Suddenly i heard two class mates discussing about the online help. I turned around and asked them to tell me the details as well and they opened up saying that there is online help we get even on physics.

I rushed back home and sat in front of the system and hunted for sites which will help me in physics help and i got it. I found the same tutor who once helped me in solving the problems on how many sides does a polygon have? I was so happy to see him back and thanked him a lot.

probability quiz

What if i start asking you probability quiz will you guys be able to answer the probability questions?

It sounds like fun guys, just imagine having questions on events, random experiment, sequence experiments or possible outcome and may be much more.

For example:-

James tosses two different coins simultaneously, what is the probability that he gets at least one head?

a) 2/3 b) 4/3 c) 3/4 d) 1/4

We can work on this example with probability right.

Guys, how about have quiz on triangle proofs in our next post. Give me your comments and if you want me to work on it.

identity property of addition

Do you remember working on identity property of addition earlier? We have also solved many problems on addition earlier, now lets work on it more with some simple examples of various property below...

Example: 1

Which of the following expression is the example of identity property of addition?

a) 9 × 1 = 9

Math enrich

Guys today we will discuss on enrich maths problems in simpler solving methods in maths. We have worked on many simple math problems which has worked helpful to you all.

Mathematics is the study of properties, capacity, sets, using numbers and symbols, right this is what we have learn t and the elementary maths operations are addition, subtraction, multiplication and division. Algebra, geometry, calculus are concept of mathematics.

Here below lets see a few example problems to learn math enrichment.

Example 1:

Solve for x: 15x-3 = 5x+67.

Solution:

Given expression is, 15x-3 = 5x+67.

Subtract 5x on both sides, 15x-3-5x = 67

10x-3 = 67

Then add 3 on both sides, 10x = 70

Now, divide both sides by 10,

x = 70/10

x = 7 (answer)

Are you aware of related rates problems and solutions, if no don't worry i will come back with the concept shortly.

Simplify sqare root

Good morning guys....happy to see you all again.. well friends, today i have come up with simplify square roots problem. I have observed many of you guys requesting to find the simplify square root of 40.


Simplify the square root of 40?

Solution:

The given number is 40

Square root of 40 can be expressed √40

Very smallest factors of 40 = 2 * 4 * 5

Square root of 40 = √40 = √2 * 4 * 5 we know √a * a = a

So, √2 * √4 * √5

we know √2 = 1.414 , √4 = 2 and √5 = 2.236

= 2 * 1.414 * 2.236

= 6.323

Answer: The Square root value of 40 is 6.323

9th Grade math help

Morning Folks!!! guys i am here with grade 9 math simple problems which will be as useful and full of information as you found my post which was for 7th grade math problems.

Problem No1:-

Adding the polynomial 3x4 – 4x2 + 5x + 3 and 4x + 7x3 – 6x2 – 1.

Solution:

Use the associative property and distributive properties we get the

(3x4 – 4x2 + 5x + 3) + (7x3 – 6x2 + 4x – 1) = 3x4 + 7x3 – 4x2 – 6x2 + 5x + 4x + 3 – 1

= 3x4 + 7x3 – (4+6)x2 + (5+4)x + 2

= 3x4 + 7x3 – 10x2 + 9x + 2.

Look at the following method which is very helpful when adding two polynomials

3x4 +0x3– 4x2 + 5x + 3

0x4 + 7x3 – 6x2 + 4x – 1

____________________
3x4 + 7x3– 10x2 + 9x + 2

Volume of a cube

Friends, as i mentioned earlier i am back with volume of a cube :-) now lets work on it. But how about the definition of a cube? Do we know that? I am sure some of us know it and some of us do not know it. Lets learn that...first...

Definition of cube:- It is a solid figure whose length, width and height are all equal. The side length of cube is called its volume.

The volume of the cube is given by the following formula.

V= a*a*a
V=a³ cubic units.

Here V is the volume of the cube, a is the side or the edge of the cube.

I will have many gk questions in my next post check on those post and improve your knowledge on math...

Circle Properties

Friends, i have a picture of a clock here towards your right...what do you see in it? What is the first thing which comes to your find when you see this clock? Yes you are right it is the shape of the clock i.e. circle......basics of geometry.

I have the definition of circle already discussed with you earlier.

Today i am here to discuss on circle and circle properties. Look below for the properties of circle.




* The arc of a circle contains two points on the circle and all of the points on the circle that lie between those two points.

* Chord is a segment and having end points which is on a circle.

* Diameter of circle: Length of the diameter = 2 × length of the radius.

* Circumference of a Circle: Circumference = 3 × diameter (approx.).

These are the properties of learning circles.

An easy concept right....Well friends i will come back again with some more interesting concept in my next post. Tangent circles would be a good topic right..well watch out for it.......

Geometrical Objects

Let Us Learn About Geometrical Objects

Point

A point is the most fundamental object in geometry. It is represented by a dot and named by a capital letter. A point represents position only; it has zero size

Line

A line can be thought of as connected set of infinitely many points. It extends infinitely far in two opposite directions. A line has infinite length, zero width, and zero height. Any two points on the line name it. The symbol ↔written on top of two letters is used to denote that line. A line may also be named by one small letter

Collinear points

Points that are lie on the same line are called collinear points. If there is no line on which all of the points lie, then they are non-collinear points.

Plane

A plane has an infinite set of points forming a connected flat surface extending infinitely far in all directions. A plane has infinite length, width, and zero height (or thickness). It is usually represented in drawings by a four-sided. A single capital letter is used to denote a plane. The word plane is written with the letter so as not to be confused with a point

Postulates:

Postulate 1: A line contains at least two points.

Postulate 2: A plane has at least three non-collinear points with it.

Postulate 3: If we cross through any two points, there is exactly one line.

Postulate 4: If we cross through any three non-collinear points, there is exactly one plane.

Postulate 5: If two points lie in a plane, then the line joining them lies in that plane.

Postulate 6: If two planes intersect with each other, then their intersection is a line.

Integers

I have discussed about what are integers in my post earlier also, but i wanted to discuss this in more details and know why is there a need of integers. There are many sites now a days who gives you complete online help to calculate integers. Visit these sites to improve your knowledge on this. Lets begin...

Introduction of integers:- Integers are set of positive numbers and negative numbers along with zero. They are also called as directed numbers, Each directed number is descreibed in terms of its numerical value an the direction. These numbers are used whenever opposites are involved.

On the number line, 0 is the origin or the starting point. All the natural numbers are to the right of 0. Have you looked at the number line. Look and observe it.

Need for Integers:- Why do you think integers are used? For example when you measure the height of a tree, it is always taken from ground level or the surface of the earth to its top. Here the ground level may be considered as 0, that is the origin. Same as the number line 0 is the origin(mentioned above). Therefore to measure them we need integers.

To distinguish numbers on the sides of 0(either above or below 0 and to the right and left of 0) opposite signs (+positive and -negative) are used. The positive numbers are mentioned in the right of the origin or zero and the negative numbers are mentioned to the left of the origin or zero.




To understand the concept better look at the image above, this gives you a clear picture on number line. Let me know you comments on this. Was this post useful? Feel free to put your views.
