A contractor bought 8.2 ft2 of sheet metal. She has used 2.3 ft2 so far and has $106.20 worth of sheet metal remaining. The equation 8.2x - 2.3x = 106.2 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square foot?

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
