Answer:
$150
Step-by-step explanation:
Let the account earns 5% APR as simple interest for the invested principal.
Now, the formula of simple interest gives that,
, where A is the final amount, P is the principal amount invested, r is the % of interest and t is the number of years for which the principal is invested.
So, the interest earned will be given by,
Hence, in our case, $300 is invested for 10 years at a simple interest of 5%. So, dollars.
Therefore, the amount of interest earned will be $150. (Answer)
According to Remainder Theorem for the polynomials, for every polynomial P(x) there exist such polynomials G(x) and R(x), that .
When the polynomial in P(x) is divided by (x + a), then there exist such polynomials G(x) and R(x), that P(x)=(x+a)G(x)+R(x). Note that for x=-a:
This means that P(-a) is the remainder, not P(a). <span>
