there is one more software ,i.e, HIDE IP EASY to hide your IP address.
But then the ultimate truth is that it is nearly impossible to really make our connections 100% secure.

well, search engines sell our information for there profit but this way they also get to know our preferences.For ex. each time we click on a link,the results we get the next time is somewhat based on that(if you notice it closely you will find it).Also now many search engines like Google use https which prevents  our privacy a lot. Even in the adds that appear on various websites, you will find that if you click on one,the next time you open that website there will be adds on similar products.This is all based on the browser-server interaction.So that means we are nowhere safe as per perfect privacy is concerned!!!!!

this reminds me of something gandhiji said, "power doesn't corrupt,fear corrupts.Perhaps the fear of loosing power".

thnk u so much for making it so simple and easy to understand.
i was really confused between aldehyde and ketone that why they have same formula inspite of different functional groups and you cleared it all.
thnx again. smile

Well, L+y is the slant height of the whole cone, right?

as per bob's diagram, YES.

#421 Re: Help Me ! » slant height of cone » 2013-10-12 00:53:44

i completely agree with u bob , i think the options printed there are wrong.
thnk u for helping smile

#422 Re: Help Me ! » slant height of cone » 2013-10-11 17:18:09

thnx bob and anonimystefy but there is nothing extra info. given apart frm what i mentioned above . And i tried but couldn't figure it out.
all i can say is that in the book the answer is given as option b). pls see if you can bring it out using some methods .

this ques. is based upon vol. and surface area.
the ques is an MCQ one.

Q.slant height of the cone of which the frustum is a part ,is equal to

options:-

a) hr1/(r1-r2)

b) lr1/(r1-r2)

c) (h+l)r1/(r1-r2)

d) h(r1+r2)/(r1-r2)


please help me out along with the process to solve this.

well i have 3 questions here which are prove based

Q.1.if the roots of the equation (x+a)(x+b)+(x+b)(x+c)+(x+c)(x+a)=0 be equal,prove that 2/b=1/a+1/c .

Q.2. prove that the equation x^2(a^2+b^2)+2x(ac +bd)+(c^2+d^2)=0 has no real roots,if 'ad' is not equal to 'bc'.

Q.3. if p , q, r and s are real numbers such that pr=2(q+s), then show that atleast one of the equations x^2+px+q=0 and x^2+rx+s=0 has real roots.


these questions are given in srijan mathematics for class 10.please help me solve these!
