I don't know the rest but good luck.
Answer:

Step-by-step explanation:
We have to find the derivative of the following function:
Now, differentiating both sides with respect to x we get,
⇒
(Answer)
{Since, we know that,
and
}
From 2000 to 2011, there are 11 years. From the given function, we can calculate the profit for a small business at the end of 2011 by substituting 11 to the x of the given equation.
y = (30,000)(1.06)(11)
y = 349,800
Thus, the profit at the end of 2011 is approximately $349,800.
I'm not sure but I'm gonna guess that the answer is 50?
GCF = 3a^2b
Solution: A, u are correct :)
