ANYONE? please :( A certain company manufactures three types of shade cloth. The product with code SC50 cuts out 50% of harmful UV rays, SC75 cuts out 75% and SC90 cuts out 90% of UV rays. In the following questions, you will need to consider the amount of UV light let through. (a)...

Hi, how would i sketch the graph any of these graphs? Is there a method i can use a) Y = cosx + sinx? and b) Sin2x-sinx ? Thank you :)

oh nvm i understand now.. lol

Ok thanks guys.. Still a working progress , marks are pretty close between ranks so I can still improve I think Question tho.. I'm not sure how realistic it is, but is it possible to get an Atar of 97 if improve ranks even more if so do I have to be like top 5 for everything or?

Yeah it's advanced eng

School rank is around early 300's Maths 11/34 Legal 1/21 Religion 1 unit 8/58 Mths ext 7/19 Va 9/36 Eng 13/16 (difference between ranks are all pretty close but still my weakest subject) What rank should I get as a minimum to get 90 or above? :(

Jane's mother puts $300 into an account at the beginning of each year to pay for Jane's education in 5 years time. If 6% p.a. interest is paid quarterly, how much money will jane's mother have at the end of the 5 years? Answer is $1788.79

My jaw just sorta locked on the right side only, so I couldn't open all the way but then doing the same thing it unlocked . Though now everytime I my mouth open and closed i can hear all sorts of cracking sounds :( I'm freaked out and I don't want to wake anyone up

Yeah, what do you mean it's wrong? :/

bare with me, its my first time attempting induction...I'm having problem with q2 . 1. Prove 3+10+17+...+(7n-4)=n/2(7n-1) for all n is equal or above 1. I could do that question, since the difference was 7, and i could do step 2. Assume. Though in this other question, 2...

Hey thanks for your help, but what i'm stuck with is before i get to the simultaneous part, how do i add the like terms? if none of them are? Sorry if this may be a stupid question :// Cause don't you get ax^2+4ax+4a+bx^2+6bx+9b+cx^2 etc..? Thanks

I've been able to get the answers right by guessing the number and checking them for questions as such: Find the values of a,b, and c if: a(x-1)^2 +b(x-1)+c = x^2 etc But i can't guess this one, so is there an actually way to do this without guessing? A method or something d)...

what would the changes be to a 2012 published version of the Cambridge mathematics 3unit book compared to a 2009 version? Does it matter, if i just use the 2009 version ?

I have another question... if anyone could please help me, idk how to approach the question at all? Use the identity cos2theta = 1-2sin^2theta to find sin^2 15 How do i start this?

oooohhh. Thanks, my bad

yeh cosAcosB + SinAsinB - CosAcosB - SinAsinB ------------------------------------------------- SinAcosB+CosAsinB + SinAcosB-CosAsinB Top line, don't they just all cancel out? then im left with the bottom of 2sinAcosB then how do i get to tanB

show me please?

How do i prove this identity? cos(A-B)-cos(A+B) / Sin(A+B) +Sin(A-B) = TanB
