Quadratic Equation: Quadratic equations have many applications in the arts and sciences‚ business‚ economics‚ medicine and engineering. Quadratic Equation is a second-order polynomial equation in a single variable x. A general quadratic equation is: ax2 + bx + c = 0‚ Where‚ x is an unknown variable a‚ b‚ and c are constants (Not equal to zero) Special Forms: * x² = n if n < 0‚ then x has no real value * x² = n if n > 0‚ then x = ± n * ax² + bx = 0 x = 0‚ x = -b/a

Chapter 25 Electrical Power and Domestic Electricity Checkpoint (p.197) 1. The heating effect of current increases with the applied voltage across the wire. Microscopically‚ when a voltage is applied across the ends of a metal wire‚ an electric field is set up between the ends. The free electrons are accelerated by the field and collide frequently with the metal ions in the wire. Thus‚ some energy is transformed into the internal energy of the wire. When the applied voltage increases‚ the electric

Planning each table in this database will be a time consuming process. After you complete these two tables‚ challenge yourself to plan other tables. This requires reviewing what data is already being collected‚ what data is not being collected‚ and what outputs the stakeholders at 4Corners Pharmacy want to see. You must then brainstorm

Chapter 5 covers many examples of why the media treats children as a special audience. Potter first explains that children have a lack of experience and maturation with the media. He underlines the importance of a good elementary education for gaining more experience‚ being educated‚ and aware of certain media messages. Children have a lack of maturation which is why Potter clarifies that there are certain things a child can learn at certain ages in their lives. The author emphasizes that cognitive

The media equation is a theory developed by two professors of communication‚ Byron Reeves and Clifford Nass‚ at Stanford University. The theory is simple. They state that people treat the media as if they were real‚ hence the equation: media = real life. Basically Reeves and Nass are saying that people on an unconscious level perceive the media as real. People view objects of the media are talking to them personally. Reeves and Nass view things such as computers‚ televisions‚ radios‚ and other

to collect the data from the experiment‚ and then taking our data and presenting it and our results in a report. Method: For this experiment‚ the goal was to use a simple pendulum (shown to the left) to measure the period of the motion. For task 1‚ we just became familiar with DataStudio and learned how to use it to time each “swing” of the ball on the end of the pendulum. Then‚ in task 2‚ using the materials provided we decided that the variables that would have effect on the period are
