Lim [x + sin(x)] / [2x – 5sin(x)]
x→∞

I know what the answer is. I just want to know if L’Hopital’s rule can be used to find that limit. If not, why not; and if so, show me how.

1) If something is $11.00 and it has a 20% discount what would you get. Then the same thing is 11.00 and the sales tax on it is 8.5% what would you get? And finally, what would be the final cost of the item?

2) Please do the same thing but the item is $4.75. It is with the same 20% dicount and 8.5% sales tax.

3) Last one is $14.00 and the 20% discount and the sales tax is 8.5%. Thank you!

Find the derivative function of:
f(x) = (4x^2-5)^4

This is what I've done so far:

4(4x^2-5)(8x)=

f'(x)=4(32x^3-5)

Can someone check to see if I'm right?
