25 is wrong.

Answer 7

The rest of it looks fine.

Answer 8

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

Answer 9

ok how do i figure out 25?

Answer 10

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

Answer 11

Then you are correct ^_^ .

Answer 12

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

Answer 13

Yep :) . To me.

Answer 14

thank you soooooo much! :)

Answer 15

You are welcome! :) .

Answer 16

Don't you feel confident enough with your answers?

Question 4 looks incorrect - there aren't two real roots, there's two conjugate roots (the discriminant is sqrt(-11))

for standard form in Q18, you should divide the whole equation by 9 (standard form of an ellipse is = 1)

for 21, it looks like you only posted the coordinates of one of the foci. The other would be (-2, 3+2sqrt(2))

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)

27 should be ln12/ln5, how'd you get ln5/ln10?
