I did what you said. I got this -> (2x+5)(4x-11)^6 + 24(x^2 + 5x)(4x-11)^5 Ok, how am I supposed to factorise this? Is it (4x-11)^5 {(2x+5) + 24 (x^2 + 5x)(4x-11)? Thx man

Ye thx, i did that one already :). Can you guys help me out with this? I did it, but what i got is a long as...equation which i think is wrong. y = (x^2+5x)(4x -11)^6

mhm thx man :)

Use the product rule to differentiate. y= x^2 (x^3 - 2x + 5) y = (7x^3 -1)(2x^2 + 6x + 5) THX

mhm ok, thanks man :)

A fruit bat uses echo location to navigate in the dark. A hovering bat emitted an ultrasonic sound wave of frequency 20 kHz. A return wave reflected from a large tree was detected by the bat 0.50 seconds after the original wave was sent. If the speed of sound in air is 340 m/s, how far away was...

Title... Also, if their is no answers/marking scheme...how can you be so sure that your answer..is like perfect/correct?

mhm...nice point.

Yo, can I just ask...when you do your practicals, do you actually have to set up the experiment yourself? or is the stuff already done up for you? Like setting up ammeters, voltmeters, transformers. wires etc? just asking...

Picking up :), but do you's find it weird if a guy randomly approached you on the streets? Like shopping centers, trains etc?

mhm ye that's the answer. Thx man :)

Describe the locus of a point which moves equidistant from the points (0,2) and (0,-2)? I've the answer, but i still don't get it. Working out will be nice THX

Lol ye I've seen that XD.

Yo, selling stuff from by BP if anyone is interested.... IGN: ZokunuZer0 ,

mhm ok thanks :) . What about Trichloromethane , CHCI3?

So...are my answers right?

Bump...Ok thx for answering but how is NCI3 polar? Nitrogen and Chloride both have 3.0 negativety, any difference from 0.0 - 0.2 are considered "non-polar" right? This is what I think it is: Nitrogen Trichloride (3.0,3.0 Electronegativety) No Polar Bonds < --- Since it doesn't have polar...
