Hugh transferred a balance of $3050 to a new credit card at the beginning of
the year. The card offered an introductory APR of 6.7% for the first 4 months
and a standard APR of 32.8% thereafter. If the card compounds interest
monthly, which of these expressions represents Hugh's balance at the end of
the year? (Assume that Hugh will make no payments or new purchases
during the year, and ignore any possible late payment fees.)

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
