ANSWER
The vertex of the graph of
is
EXPLANATION
The vertex form of a parabola is given by
where
is the vertex of the parabola.
The function given to us is
This is already in the vertex form.
When we compare this to the general vertex form, we have,
and
Therefore the vertex of the parabola is
Hence the correct answer is option A.

Answer:
A = 374.123 ft^2
Step-by-step explanation:
First, lets calculate the perimeter:
Perimeter (p) = side length (s) * number of sides (n)
Next, lets find the apothem, which is the shortest length from any side to the middle. It's like the radius in a circle, but more complicated.
Apothem (a) = side length (s) / ( 2 * tan(180/number of sides (n)) )
Now, finally, to find the area of a regular polygon, we use the following equation:
Area (A) = ( apothem (a) * perimeter (p) ) / 2
Turning into a decimal:
Answer:
She will be charged $180 once lets the account go past 6 months before making a payment.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
In this question:
If she pays within 6 months, she is not charged any interest.
However, if after 6 months she has not paid the balance, she is charged 20% interest for this period.
Barbara financed a new bedroom set at the furniture store for $1,800.
This means that
20 percent interest
This means that
How much interest will she be charged once she lets the account go past 6 months?
6 months is half a year, so this is E when
She will be charged $180 once lets the account go past 6 months before making a payment.
