So we have

-3 - 2(4) + 2.6/2

1st, perform the division

-3 - 2(4) + 1.3 =

-3 - 8 + 1.3 =

-11 + 1.3 =

-9.7

w - 2x + y / 2

PEMDAS: -3 - 2(4) + 2.6 / 2

-3 - 8 + 1.3

Now, left to right since we have only addition & subtraction left: -11 + 1.3 = -9.7.

Oh, it was a riddle! 

Well holidays and money means adventure time and exploration of all countries! Challenge: Visit every single spot on the Earth! By spot, I mean that it must have at least 100 inhabitants within a 5 mile radius!

You all have given the answers just by only thinking with your brain and not exceeding the limit of your thinking power becoz the answer of that when will u get the longest lasting holiday isnt your current or coming soon holidays the answer is something u might have never imgined!

the answer is that when u all get old then u all will get a holiday forever!now i hope u can find out the reasons for why this is the answer!

Sorry none of you could pass the riddle!

And now for what u wish everyday then mybe for Zegroes its super power and Aziz jobs!but let me tell u both that u dont wish for super power and jobs since u were a kid becoz im sure children arent interested in jobs and super power mu8ch when they are a kid!okay!i agree, in super powers maybe they wish but not that much than that of they wish for a holiday!becoz they really get tired with the school work or going to the play school and just want a holiday!

so with this we come to know the answer of the riddle that a human being since they are a child and all their life wish for a holiday the most!

And money is another thing that people also wish fot most as even children have thesekind of wishes when they come to know what is money ans its real meaning!

Thanx david .. you are amaizng 

now I want to ask about question 16 .. I saw that you have long discuss with alan .. and the English is not my mother language .. so I want some one explain to me the answer with simply .. why it is not specific heat capacity ... 

Thanx 

Let's take it from your third step, Stu

lnQ=1/5t + C

We don't really need to exponentiate both sides...just write this in exponential form....so we have...

e^[(t/5) + C] = Q

Ce^(t/5) = Q

And when t = 0, Q = 50....so C = 50   and we have

Q(t) = 50e^(t/5)

Oh i was there. Thanks.

Brackets were applied to the fraction because it could be read as Q = 50e^1/5t [Note 5t is in the denominator].

Your Welcome!

Because the initial condition gives P as some function of t. and we know that when t = 0, P = 20.

Think of P as being P(t)........kind of like  "f(x)" that you were used to dealing with in Algebra.

What makes you solve it as P= and move everything else?

Separating the variables and integrating, we have

∫1/P  dp  =  ∫.02 dt

ln P = .02t + C

This says that

e^(.02t + C) = P    .....or.....

(e^C)* e^(.02t) = P

And e^C is just a constant....we can just call it "C"

And we have P(0) = 20   .... so...

Ce^(.02(0)) = 20

 Therefore, C = 20

And our answer is

P = 20e^(.02t)

I hope this helps.....

Question 1 of my last post. I am not sure why it is positive answer from your post. That is that i should or shouldnt use signs when using Fe equations in front of proton charge or electron charge? As well i am unsure what is R^3 in your equation. We have gone through materials but resolved everything to Fe=kq1q2 / r2, F=q0E=kq/r2, v=kq1q2/r. Oh and here is (in my notes) q=Qr^3/R^3 WHICH IS THE DIFFERENCE OF A SHELL IN AN INSULATOR WHERE R IS the outter radius.  

 For question 2 of the avove post. what i did wrong which on posting last night i kind of figured OUT was: firstly I took e to be electron. I took F to be Fe which iM doing a lot. And the rest of my approach was ok but that my calculator is tempremental when solving for tan-1(3.3/6.9) which it cannot do in one step accurately. 

Convert the percentage to a decimal and add 1 to it. Then, multiply this by the number.

For example......suppose 4 is increased by 50%......convert 50% to decimal form = .50

Then, add 1 to this = 1.50

Now, mutiply this by 4 =

4*1.50 = 6

And this is true since 50% of 4 = 2.  And we've increased 4 by 2, or 50%

The top button is for the  numerator and the bottom button is for denominator.

If you are south of the equator then it is the other way aound.

3x + 5 = -11

3x = -16

x = -16/3 = -5.3333333.

No problem.

Oh ok, I forgot about moving the decimal. I knew it was .33% but I didn't know how I got the answer so I wasn't sure. Thank you very much :D

1/300 is the same as 0.003333.... --> Move the decimal place twice to the right and you get 0.33...% (repeating decimal).

All you have to do is divide 21 rad/s by 2pi --> 21 rad/s / 2pi = 3.342253805 rev/s.

1/4 of 400 = 0.25*400 = 100. You can think of this as dividing 400 in to 4 equal pieces --> 400/4 = 100.

$$\boxed{FV=Pe^{rt}}$$

t =   $${\mathtt{8}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{135}}}{{\mathtt{365}}}} = {\frac{{\mathtt{611}}}{{\mathtt{73}}}} = {\mathtt{8.369\: \!863\: \!013\: \!698\: \!630\: \!1}}$$   years

r=  0.0865

FV= 2250000

Plug the numbers in to get the present value P    

There are a couple of different ways of inserting a square root sign. 

1)    Under insert there are special characters and √ is on the 3rd row in the middle.

OR

2)   you can use the math formula button

 x*sqrt(2)+y=3+sqrt(18)  would look like 

$${\mathtt{x}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{2}}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{y}} = {\mathtt{3}}{\mathtt{\,\small\textbf+\,}}{\sqrt{{\mathtt{18}}}}$$

3)   I use the LaTex tab but the 2nd option is probably the best for you.

$$\\x\sqrt2+y=3+\sqrt{18}\\
y=-x\sqrt2 +3+\sqrt{18}\\
y=-\sqrt2 x +3+\sqrt{9*2}\\
y=-\sqrt2 x +3(1+\sqrt{2})\\$$

Now this is the equation of a straight line (linear equation) so there are an infinite number of solutions.

The gradient is $${\mathtt{\,-\,}}{\sqrt{{\mathtt{2}}}}$$   and the y intercept is  $${\mathtt{3}}{\mathtt{\,\times\,}}\left({\mathtt{1}}{\mathtt{\,\small\textbf+\,}}{\sqrt{{\mathtt{2}}}}\right)$$
