Use L'Hopital's Rule.
Since substituting pi into the equation renders 0/0, we need to take the derivative of both, the numerator and denominator and then using the limits again.

\lim_{x \to \pi} (\frac{-sinx + 2cos(2x)}{2x})
Now, substituting pi into the equation renders \frac{0 + 2}{2\pi}

So, our limit becomes \frac{1}{\pi} (ie B)

marin [14]

Answer:


No, This is not reasonable estimate.  

Step-by-step explanation:


Charles wants to take out a 5 year loan on car that cost $15000.  

He make rough estimate to make payment. He can afford to pay up to $200 per month.  

First we find total number of months in 5 years.  

Total months = 5x12= 60 months

Total estimate to pay = 60\times 200 =$12000

we can see cost of a car $15,000 is greater than his estimation $12,000.  

Therefore, Charles estimation will not work.  

No, This is not reasonable estimate.
