<h2>
Part 1.</h2>
Answer: 
The limit of the difference quotient is simply the derivative, so we can express this as follows:

So our function is:

Taking the derivative, we have:

So the correct option is:

<h2>Part 2.</h2>
Answer: 
The equation of the line that passes through the same point can be found as:

Where
, so we need to find
. Plug in that x-value in the function we have:

And the slope is:

Then, the equation of the line is:

<h2 /><h2>Part 3.</h2>
Answer: Shown below
As you can see below, the graph of the function of
is continuous. This is so because we have plotted a polynomial function whose domain is the set of all real numbers. So the function is defined at the point
, so the derivative exists at this point, hence we can calculate a tangent line there. In conclusion, we get the graph shown below. The blue line is the tangent line while the red curve is the graph of 
Answer:
11
Step-by-step explanation:
H =V/(LxW)/3
H = 297/(9x9)/3
H = 297/(81)/3
H = 297/27
H = 11
Therefore, the height of the pyramid is 11ft square
Answer:
oh ok. So, first, you get the equation in the form y=ax2+bx+c. Next, you calculate -b / 2a. This is the x-coordinate of the vertex. Then finally, you plug in the value of -b / 2a into the equation into the x variable and solve for the y variable. This is the coordinate of the vertex.
Step-by-step explanation:
Hope this helps!
Answer:
Step-by-step explanation:
In the given trianle all sides are equal. So, it is equilateral triangle.
So,each angle is 60
Reason for x = 60,
Two lines are parallel. So alternate interior angle are equal.
Answer:
75.06239187
Step-by-step explanation:
1/2bh= Area of a Triangle
6^2+b^2=8.5^2 because we are missing a side we need to use the pythagorean theorem.
36+b^2=72.25
b^2=36.25
b=6.02
6.02+19= base
25.02
Now area
1/2bh
1/2 (25.02*6)
25.02*6= 150.1247
150.1247/2= 75.06239187 is Area
The above decimals before area are rounded.
