Savannah is going to invest $220 and leave it in an account for 12 years. Assuming the interest is compounded continuously, what interest rate, to the nearest tenth of a
percent, would be required in order for Savannah to end up
with $430

5.7%

Step-by-step explanation:

The formla for calculating compound interest is expressed as;

A = P(1+r)^t

A is the amount = $430

P is the principal = $220

r is the rate

t is the time = 12 years

Substitute and get r;

430 = 220(1+r)^12

430/220 =  (1+r)^12

1.955 = (1+r)^12

1.057 = 1+r

r = 1-1.057

r = 0.057

r = 5.7%

The interest rate is 5.7%

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
