Let us see

Let us see
It was
x^2 + y^2 = 5
3x + y= 7

had to find the two pints of intersection of the line.

No problem haha
10. i got a question i need help with

find: dV/dt

V=1/3t^6 - 2t^4 + 3t^2, for t is equal or greater than 0

All you have to do is differentiate like you did in core 1
12. thank you
13. i don't understand how this works?

express root63/3 + 14/root7 in the form of nroot7?

sorry is that meant to be 14 divided by root7? Or just 14root7?
15. (Original post by The H)
sorry is that meant to be 14 divided by root7? Or just root7?
yeah 14 divided by root7.

where have you been all that time? :P
16. (Original post by ..Bakhtawar..)
yeah 14 divided by root7.

where have you been all that time? :P
Haha sorry
root63 is the same as root(9x7), if you root the 9 then you get 3root7
(3root7)/3 = root7 so that's that part done

14/root7 is the same is (2*7)/root7, since 7/root7 is root7, then 14/root7 is 2root7

so root7 + 2root7 is 3root7
hope you followed that
