Question 56292: Please can anyone please help?
Compounded semiannually
P dollars is invested at annual interest rate r for 1 year. If the interest is compounded semiannually, then the polynomial P (1 + r/2)^2 represented the value of the investment after 1 year. Rewrite this expression with out parentheses. Evaluate the polynomial if
p = $200. and r = 10 %

Compounded semiannually P dollars is invested at annual interest rate r for 1 year. If the interest is compounded semiannually, then the polynomial P (1 + r/2)^2 represented the value of the investment after 1 year. Rewrite this expression with out parentheses. Evaluate the polynomial if p = $200.
and r = 10 %
------------
P(1+r+(r/2)^2)
P+Pr+(Pr^2/4)
200+200*0.1+200*0.1^2/4
200+20+200*0.01/4
220+1/2
$220.50
