You buy a used car for $12,000. It depreciates at a rate of 15% per year. If this trend continues a) Write an exponential decay function that models the profit in dollars over time.
b) What is the value of the car after 1 year? Write only the number with no comma.
c) What is the value of the car after 5 years? Write only the number with no comma.

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

ask the math teacher she or he would know lol.

step-by-step explanation:

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
