we know that
The vertex of the function is the point
The vertex of the function is the point
The x-coordinate of the vertex is equal to h
the y-coordinate of the vertex is equal to k
so
the value of h is
the value of k is
the equation is
therefore
<u>the answer is the option a</u>
Invested amount (P) = $300.
Time in years (t) = 2 years.
Balance after 2 years (A) = $329.49.
Let us assume rate of interest = r % compounds annually.
We know, formula for compound interest
Plugging values in formula, we get
Taking square root on both sides, we get
r=0.048.
Converting it into percentage by multiplying by 100.
r=0.048 × 100
r = 4.8 %
Therefore, the rate of interest on the account is 4.8% compounds annually.
