AB Review Treasure 13

Did anyone get Treasure 13 with the equal areas under the curve? When I integrate I end up with a quartic equation that I can't solve by hand, and I don't see how it can be simplified down. Does anyone know how to solve the equation?
Sorry about the previous post. I meant Treasure 13 instead of Location 13 and don't notice until Priya responded.

I need help!!!!

Did anyone do the suspect problem for Set#19. I did it a couple times but I can't get an answer that makes sense. Can someone help me?

AB Review Location 13

Does any one know how to solve location 13? I can't solve the quartic equation I end up with for k. There's no use of graphing calculators and it doesn't seem like the equation can be factored. I don't see any way to simplify the equation and so far the rest of my work seems right. Did any one get an answer?

Calc AB Review Question

Did any one else get a negative answer for any of the review questions? I seem to get a negative answer for Location #4. I think I've done something wrong since I haven't used the interval on this problem, but right now I don't see any other way to approach this problem. I'm pretty sure none of the answers are supposed to be negative. Did anyone else have this problem?

FR SET #5 1990 AB3

Hi, I am Michael Cupino from period 3. In FR Set #5 1990 AB3, I understand all the concepts of finding area and finding volume. Only thing that I couldn't do was solve for x, which is probably an Algebra thing, but I'm having a hard time finding x without using a calculator.

y=e^x, y=(x-1)^2
I'm having trouble solving for x.

e^x=(x-1)^2

"ln"ing both side did not help. I can find out where they intersect on the calculator, but this is the no calculator part. So it'd be great if someone could go over this little algebra problem.

Openers

Is there going to be an opener tomorrow for the AB review? If so, what kind of material is going to be on it because the AB was a mix of things. Please let me know.
And also, Mrs. Carlson, is there any source of extra credit possible for first semester to help those in need?
Thank-You

Need Help on Chapter 8 review

On the Chapter 8 review, can someone explain number 21 for me. The part where they make x into (1/x). It's toward the end. It would be very helpful.
Thank-you. Jennifer Oh

8-1b Notes Hospitals Rule

Hi I just wanted to share today's notes. It's typed and in a pdf file.

The download will only be available for 7 days.

My apologies!!

This time truly check the EDLINE page for the correct HW assignment. Omit #3, 7, 13 until tomorrow. Add in #31 (from tomorrow's HW). It's just a little switcheroo.

I will go over all that "Ln" stuff tomorrow, don't worry!

Can someone explain #7?
I don't understand how to get the right answer.
