By Oswaldo Montalvo Elizabeth Gallo Nelson Reyes **__ QUADRATIC FORMULA __** A quadratic equation (second grade) with one incognito, it is an equation in the suitable way, where //a//, //b// and //c// are real numbers given, with //a// different to zero. They can solve themselves using the quadratic formula. If b2>4ac there are two different real solutions; if b2=4ac there is only one real solution; if b2<4ac there are not real solutions, but there are two conjugated complex solutions. If the solutions for are and when we apply the formula below: For example: a = 5 b = -6 c = 1 ;   **__ GEOMETRICAL THEOREM __** Over 2,500 years ago, a Greek mathematician named Pythagoras proved that the relationship between the hypotenuse and the legs is true for all straight triangles. He said: “In any straight triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs” This relationship can be stated as: and it’s known as the “Pythagorean Theorem” For Example: Find x x = c  **__ WHICH ARE NEWTON LAWS? __** We can enunciate the three laws of Newton in the following way: Call also principle of inertia; all continuous body in rest or constant speed if there are not external forces that act on the, this is been worth when one works from inertial marks of reference. This explains that an object remains in rest or a billiard ball moves with constant speed. This you can express this way: Fundamental law of the dynamics that settles down that the relationship between the force applied to a body and their acceleration is a constant. = k  where k is the mass of the body. We can say that: F = ma Where it is observed that if F = 0 then a = 0 and you arrived to the first law or principle of inertia. Called action law and reaction; to all action it corresponds a reaction, this expert in terms of forces. When we are stopped in the floor our body exercises a same force but of sense contrary to the one that the floor makes to support us, equally when we push a door, the force that we exercise on the door is same but of sense contrary to the one that the door exercises on us, alone that our mass makes that the friction with the floor doesn't allow to move, the door on the other hand moves easily. It is good to clarify that this couple of forces is applied on different bodies, if it was on the same body a sum of forces similar to zero it would be given and there would not be movement.

**HOMEWORK** Proaño Marco For the common person mathematics are like the most boring subject of all, and that is because all that they think about math is that it only has numbers. And so we think that a way to make math more interesting would be in a certain way to leave almost all the responsibility to the books editors. How is that?. Well by making more didactic books or maybe trying to write or edit the books with more understandable words. Also the books could have some pictures for the kids. Other important way to make math more interesting would be by giving the responsibility to the teachers of the subject in schools, they could teach math in a different way, maybe making the subject more participative or make it more funny for kids like a learning through games or something like that.

**ASSIGNMENT**

 * Realized by:** Santiago S. Ortiz G. y Edison G. Caiza A.


 * Give examples of statistics misused by journalist, politicians, etc.**

- The politicians misused the statistics because they changed the resoults. - When Statistics are use to give an interested interpretation. - Journalist almost always manipulate the statistics for the own interest. - Sometimes journalists make surveys in a bad part on the population. - Politicians in some cases hide the results of statistics when showing in public.

 * NAMES:**


 * TITLE:**
 * -** HOW THE PEOPLE USE STADISTIC

1) Most of people use stadistics to rate some important events, be sides stadistics is very useful to know and to get a feedback of situations that happened a long time ago. Doctors, teachers, lawyers and so on, everybody uses statistics........

2) The stadistics is used too to know about the different topics and how to find the solutions for the problems, but principaly the stadistics give or discover the exactly number of the investigations using the % ( percent ) and with it the people could know the maximun or the minimun percent of the investigation in order to give their own opinion about it........

3) The stadistics is used in different aspects such as: education, business, poblation and so on, the estadistics set us knowing some facts, real numbers about something, nowadays it is very important, in order to manage all facts, numbers in order. The stadistics can be presented in tables, graphic, line graphics and so on and all people must use the stadistics in our lifes........
