Rajah 1 menunjukkan lengkung yang mempunyai fungsi kecerunan k - 2x
dengan keadaan k adalah pemalar. Garis lurus AB ialah tangen kepada lengkung itu di titik (1,3) dan persamaan AB ialah x+ y = 4.



Carikan
a) nilai k. . [2 markah]
b) persamaan lengkung itu. [4 markah]
c) luas kawasan berlorek . [2 markah]

does anyone have any tips or any links to tips for pendidkan islam? please do share

2lg2 - 2lg3 + lg21 + 2lg5 + lg21 + 2lg5 - lg7

= lg2^2 - lg3^2 + lg21 + lg5^2 + lg21 + lg5^2 - lg7

= lg4 - lg9 + lg21 + lg25 + lg21 + lg25 - lg7

*Berdasarkan Hukum Log (or something like that)

log A + log B = log AB

log A - log B = log A/B

maka

= lg [(4/9)(21)(25)(21)(25)]/7

= lg 17500

Don't know correct or not?

deleted: got wrong answer.
