By the polynomial remainder theorem, because <em>x</em> = 2<em>i</em> is a zero of <em>f(x)</em>, we have no remainder upon dividing <em>f(x)</em> by <em>x</em> - 2<em>i</em>.
Computing the quotient yields
Then if the remainder term is 0, follows that <em>a</em> = -12.
Answer:
The formula for an exponential decay problem is: y = x (1 - r)^x
Where x = initial amount, r = rate of decay and x = # time periods
So, x = $258, r = 8% = .08 and x = 11 years
y = 258 (1 - 0.08)^11 = 258 (0.92)^11 = 258 * 0.3996 = $103.10
