Linear Equation Lesson Plan Linear equations are used in everyday life without much thought. However, when students are first learning to set up and solve a linear equations, it seems to be a difficult task for most. There are three main formulas a student needs to keep in mind when solving a linear equation. Beyond the formulas, the most important aspect of a linear equation is the slope. In the State of West Virginia, Math 1, which is usually comprised of ninth graders, is where these standards
better prepared for life after high school no matter what field they pursue in life. Upon completion of this task, the students will have photographs of different types of lines, the same lines reproduced on graph paper, the slope of the line, and the equation of the line. They will have at least one page of graphing paper for each line so they can make copies for their entire group and bind them together to use as a resource later in the unit. This task should be fun and interesting for the students
be very inaccurate therefore causing Barbie to go too far or not far enough. Next, we found out how many rubber bands were needed by using the calculator’s equation. Our group took the height of Barbie, added the centimeters we wanted her away from the ground, subtracted that amount from the quad height and plugged that number into the equation for the “y” value. Making the correct math choices greatly affected our outcome; if we had not re-examined our work our Barbie would have not gone very far
different graphs in the program. After data collection, a linear fit and a quadratic curve was tested upon the graph of distance vs. time. It was found out that a quadratic curve would fit better for the distance vs. time graph rather than a linear fit. This shows that the distance follows a parabolic curve as time progress during a free fall. This is shown by the equation X = X0 + V0t – 1/2gt2, or D= V0t – 1/2gt2 .A quadratic equation has a form ax2 + bx + c = 0, where ax2 is –1/2gt2 , bx is
given equation is given below (Fig 1.1) 1. ‘Find the four Intersections made my the parabola x2-6x+11 and the lines y=x and y=2x’ The co-ordinates for the intersections of the parabola and the two given lines are Ans 1. To find the co-ordinates using technology graph the parabola and the two lines required, and note the points of intersection. Alternatively solve the quadratic equation but substituting the value of y = x and y = 2x Giving the two equations To find
To understand angular momentum easier it is wise to compare it to the less complex linear momentum because they are similar in many ways. "Linear momentum is the product of an object's mass and its instantaneous velocity. The angular momentum of a rotating object is given by the product of its angular velocity and its moment of inertia. Just as a moving object's inertial mass is a measure of its resistance to linear acceleration, a rotating object's moment of inertia is a measure of its resistance
Eigenvalues and eigenvectors is one of the important topics in linear algebra. The purpose of this assignment is to study the application of eigenvalues and eigenvectors in our daily life. They are widely applicable in physical sciences and hence play a prominent role in the study of ordinary differential equations. Therefore, this assignment will provide explanations on how eigenvalues and eigenvectors will be functional in a prey-predator system. This will include background, history of the concept
Gradient Function For this investigation, I have to find the relationship between a point of any non-linear graph and the gradient of the tangent, which is the gradient function. First of all, I have to define the word, 'Gradient'. Gradient means the slope of a line or a tangent at any point on a curve. A tangent is basically a line, curve, or surface that touches another curve but does not cross or intersect it. To find a gradient, observe the graph below: [IMAGE][IMAGE] All you
17th century. The simplest forms of equations in algebra were actually discovered 2,200 years before Mohamed was born. Ahmes wrote the Rhind Papyrus that described the Egyptian mathematic system of division and multiplication. Pythagoras, Euclid, Archimedes, Erasasth, and other great mathematicians followed Ahmes (“Letters”). Although not very important to the development of algebra, Archimedes (212BC – 281BC), a Greek mathematician, worked on calculus equations and used geometric proofs to prove

so proved to be the foundation of more high powered mathematical development. Number problems such as that of the Pythagorean triples (a,b,c) with a2+b2 = c2 were studied from at least 1700 BC. Systems of linear equations were studied in the context of solving number problems. Quadratic equations were also studied and these examples led to a type of numerical algebra. Geometric problems relating to similar figures, area and volume were also studied and values obtained for p.The Babylonian basis of
scatterplot of the 12 universities data is on the following page (page 2) The linear regression equation is: ACCEPTANCE = 212.5 + -.134 * SAT_SCORE R= -.632 R^2=.399 I plugged in the data into my calculator, and did the various regressions. I saw that the power regression had the best correlation of the non-linear transformations. A scatterplot of the transformation can be seen on page 4. The Power Regression Equation is ACCEPTANCE RATE=(2.475x10^23)(SAT SCORE)^-7.002 R= -.683 R^2=.466 The power
Three Methods to Find Roots of Equations There are many different kind of methods which can be used to find the roots of equations which can not be sold algebraically. In this coursework we are going to analyse the use of three of these methods which are called the: change of sign, Newton-Raphson and the rearrangement method and are going to use them to find roots of different equations. Change of sign method A root of an equation (where the graph crosses the x-axis) can be detected
happen in its equations, but chaos theory is really about finding the similarities between these seemingly random events in an equation. Edward Lorenz, a meteorologist, discovered this theory when he was working on a calculation for weather prediction on his computer. He set his computer to use 12 different equations to model the weather. The computer didn’t necessarily predict the weather. It just gave a guess at where the weather might be. Using these twelve different equations he tried running
and temperature. Boyle discovered that for a fixed mass of gas at constant temperature, the pressure is inversely proportional to its volume. So in equation form this is: pV = constant if T is constant Amontons discovered that for a fixed mass of gas at constant volume, the pressure is proportional to the Kelvin temperature. So in equation form this is: p µ T if V is constant Shown below this is represented on graphs in (oC) and (K). [IMAGE] P [IMAGE] [IMAGE] q/oC
Current Technology on Winding Linear Generators Abstract This paper is an overview of the materials and winding technology that is currently used on today’s linear generators. It contains information on the types of wire used as well as the epoxy used to hold the coil windings in place. Furthermore, it contains information on the possible orientations that the coils can have with respect to the permanent magnets. Introduction Linear generators/motors have been around since the early
Imagine spending twenty-four years in prison for a crime you did not commit. Furthermore, imagine that conviction is based on witness testimony and no valid forensic evidence. This is the case for Texas resident Steven Phillips and countless others whose unfortunate circumstances stem from the fallacious nature of human memory. Phillips was wrongly convicted in 1982 based on a few of the many inadequacies of human memory (“Know the Cases”). Unfortunately, this is an all-too-common occurrence due
I believe that time is a gift from God and it is up to individuals to make wise decisions regarding how they will invest the time that God has granted them. My perception of time dictates, to a degree, how I chose to use it. I believe that time is linear - there is a beginning and an end - God, the creator of time. For this reason, I strive to use my time wisely. One day I will be unable to live like I do now, so I believe that it is important to make the most of what time I have. However, I also
One Hundred Years of Solitude: Linear and Circular Time Cien Anos de Soledad Style in Gabriel Garcia Marquez's One Hundred Years of Solitude is closely linked to myth. Marquez chooses magic realism over the literal, thereby placing the novel's emphasis on the surreal. To complement this style, time in One Hundred Years of Solitude is also mythical, simultaneously incorporating circular and linear structure (McMurray 76). Most novels are structured linearly. Events occur chronologically, and
Systemic Change What Is It To fully understand Systemic Change, one must first be able to distinguish systemic from systematic. The term systematic often is associated with images of a linear, generalizable model of how to do something. Systemic on the other hand implies a global conception of the problem and an understanding of the interrelationships and interconnections. (Carr 1996). The systemic perspective in instructional design is traditionally limited to feedback via needs assessment
