I got a fraction, like 21/1/3 something like that...What did people get for the Volume of the solid
Yeah, I got k>32. Took me a while to think of it though because I kept thinking about the discriminant but it wouldn't work.Lol I got 14a (iv) wrong -___-
I was like wth do I do?! so I started trying discriminant but the things to the power of 4... then I substituted x^2 = u but that didnt work cause I had x^3
Then after the exam my friend said its just k>32 so the min point wouldnt cut the x axis -________- fml
Sames. I hope thats rightI got a fraction, like 21/1/3 something like that...
The answer was k<-32 mate :LLol I got 14a (iv) wrong -___-

k>32 niceYeah, I got k>32. Took me a while to think of it though because I kept thinking about the discriminant but it wouldn't work.
Sames. I hope thats right
oh fffff should it have been -32?yes k less than -32
Thats what I got i'm assuming we are right , everyone else here is either trolling or genuinely failed this questionk>32 nice
My thinking was that if you added 32, and raised the curve up by 32, the minimum point would no longer cross the x axis, hence no solutions so k>32?????Thats what I got i'm assuming we are right , everyone else here is either trolling or genuinely failed this question
19pi/72 units cubed?What did everyone get for B?
Can you show your working? I forgot what I put! ffs.19pi/72 units cubed?
I did it now and got exactly that, in the exam I got something else. FML!Can you show your working? I forgot what I put! ffs.
Correct, same for me.My thinking was that if you added 32, and raised the curve up by 32, the minimum point would no longer cross the x axis, hence no solutions so k>32?????
