- anonymous

The rest of it looks fine.

- anonymous

I CANNOT help you on the polar coordinates though as I have not learnt them.

- anonymous

ok how do i figure out 25?

- anonymous

Ohh it's 5^0 ! I thought it said 9 :P .

- anonymous

Then you are correct ^_^ .

- anonymous

ok...soo everything else (besides polar coordinates) are correct??

- anonymous

Yep :) . To me.

- anonymous

thank you soooooo much! :)

- anonymous

You are welcome! :) .

- Ledah

Don't you feel confident enough with your answers?

- Ledah

seems like you've answered them to the best of your ability.

- anonymous

Yes.. but its not about just being confident..I want to be correct

- anonymous

Aren't you going to submit it? :P .

@Dido525 question 14 looks correct for the graph of 1+3i http://assets.openstudy.com/updates/attachments/50ca22a9e4b0a14e43695095-coolaidd-1355424646452-screenshot20121213at1.40.18pm.png

The other would be (-2, 3+2sqrt(2)) http://assets.openstudy.com/updates/attachments/50ca22a9e4b0a14e43695095-coolaidd-1355424828452-screenshot20121213at1.45.38pm.png 24, asks for the minor axis vertices, and you've given the major axis vertices. Minor axis vertices should be (-3, 3) and (-1,3) http://assets.openstudy.com/updates/attachments/50ca22a9e4b0a14e43695095-coolaidd-1355424827838-screenshot20121213at1.45.51pm.png 27 should be ln12/ln5, how'd you get ln5/ln10?
