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.
The axis of symmetry for this parabola is the x-axis. The general form of the equation is:
4p(x-h) = (y-k)^2
where the focus has the coordinates of (h+p,k)
Manipulating the given equation to the general form:
4(1/3)(x-7)^2 = (y - 0)^2
Therefore the coordinates of the focus is:
(7+(1/3),0)
The answer is A.) (71/3,0)
I thin the answer is 8,9785
Equations can be solved in several ways; one of these ways is the graphical method.
The number of commercials, x, and the number of movies, y, on which Naomi's songs were played are 5 and 2, respectively.
Let:
<em />
<em> commercials</em>
<em />
<em> movies</em>
<em />
She earned a total of $300.
This is represented as:

Her songs were played on 3 more commercials than movies.
This is represented as:

See attachment for the graphs of


From the graph, the lines of both equations intersect at:


This means that:
- <em>The number of movies is 2</em>
- <em>The number of commercials is 5</em>
