By "slope" I assume you mean slope of the tangent line to the parabola.
For any given value of <em>x</em>, the slope of the tangent to the parabola is equal to the derivative of <em>y</em> :
The slope at <em>x</em> = 1 is 5:
The slope at <em>x</em> = -1 is -11:
We can already solve for <em>a</em> and <em>b</em> :
Finally, the parabola passes through the point (2, 18); that is, the quadratic takes on a value of 18 when <em>x</em> = 2:
So the parabola has equation
The negative sign shows that they still owed $5000 to the creditors which shows a loss of money between June and December.
Step-by-step explanation:
Amount owed at the end of June = $3765
Amount owed at the end of December = $8765
As Hightop Roofing owed creditors the amount, therefore, we will consider the amount as negative, therefore,
Amount in June = -3765
Amount in December = -8765
To see the difference, we will subtract the amount owed in June from the amount owed in December.
The negative sign shows that they still owed $5000 to the creditors which shows a loss of money between June and December.

Answer: Option 'B' is correct.
Step-by-step explanation:
Since we have given that
Amount Josh earn each summer = $2700
Rate of simple interest = 4.5%
According to question, he deposits the same amount each year.
First summer, he deposited = $2700
In Second summer, he deposited = $2700×2= $5400
In Third summer, he deposited = $2700 × 3=$8100
At the end of his third summer, his money becomes,
As we know the formula for "Amount" that it becomes at the end of his third summer:
Hence, Option 'B' is correct.
