So when Helmholtz recognized that thought moves at a finite rate, faster than a bird but slower than sound, he missed a fundamental difference between the brain and a telegraph. In our heads, speed is not always the most important thing. Sometimes what really matters is timing.
A solution of a quadratic equation is a value of the variable that makes the equation true. Many quadratic equations. can be solved by factoring and using the zero-factor property. The Zero-Factor Property: When the product of two real numbers is 0, at least one of them is 0.
Another term that is useful in this discussion is power factor (PF). The power factor is defined as the ratio of W to VA: Power factor = PF = W/VA (5) Power factor is always a number between zero and one because the watts drawn by a device are always less than or equal to the volt-amperes.
