Slope is a better term. You can call it incline as well if you want.
 
Its fine, unless you want to go in details.

In terms of ranking;

1) Slope

2) gradient

3) incline
 
Anyone who says gradient rather than slope is just trying to show off. When you see a hill you say "thats a steep slope" you dont say "the gradient of the hill is quite large"

/case over
 


The way I use it is if the line is sloping from left to right, then it's a negative gradient and positive gradient for the converse.
 
Major what kind of a formulae was that :s To work out the area of a triangle you just do half of (base x height).

A person has a book, a ruler and a balance. How can he find the density of the book with the tools he has?

My answer is:
Density = Mass/Volume
We can find out the mass of the book by weighing it on the balance and we can find the volume of the book by measuring it with the ruler. Then, we can divide the numbers and find the density.

Am I right? If not, please provide the correct answer.
 
You are quite right, but this is not my field of expertise. :najam
 
96* is that you yh helping people with their hw B)

And yh that sounds right.
 
You need to mention more detail, as in you need to measure length, width and the height of the book and multiply these 3 to get the volume. You can't get the volume off the ruler straight. :amir

How is a mineral different from an ore?

I don't have it in my textbook and I can't find a suitable answer on internet.

Ok let's try again...

Minerals are naturally occurring substances present in the earth's crust. And what I remember from my miserable chemistry days, it will have a fixed definite chemical formula. In even more simpler terms, it means it will have the same substance throughout and not like a rock which may have different combination of elements/metals/minerals.

Ore is basically a mineral or an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined or extracted. So for your easy understanding, you can assume ore is a business end product extracted from minerals. So if I'm a businessman, then I would go: Jab bhi koi mineral dekhun, mera dil deewana bole ore ore ore... ore ore ore:P

Instructions for the above output

Write a program that computes and prints the quiz average, homework average, test average, and final average of the nine weeks for a student. Enter 2 quiz scores, 5 homework scores, and 3 test scores and a student’s name. The homework is worth 20%, the quiz is worth 30%, and the test is worth 50%. hint: find the average of each and take the appropriate percentage.

For this assignment you are required to document (comment) and leave appropriate spacing in the source code for three program blocks. They are:

[1] Enter Data Section [2] Process Data Section [3] Display Data Section

Controlling Output Format

Numbers are normally displayed with right justification. This program requires output formatting. We can control the appearance of numerical output in C++ by using several features. At this stage the output will only be mentioned and practiced very superficially.

First, you will need to add the header file: #include <iomanip.h> which stands for Input Output manipulation.

Second, use the following two, odd looking, program statements before doing any output formatting. Do not be concerned how the program statements work right now.

cout << setiosflags(ios::fixed);

Use setw to control right justification output.

Use setprecision to control the number of digits displayed after the decimal point.

Format the Quiz, Homework, and Test averages to the hundredths and format the Nine weeks average to the nearest integer.

Okay guys I need help in Microeconomics (yet another stupid core eco course for my degree).

It's pretty basic stuff, but I'm a dumb dodo when it comes to math and eco.

Inverse demand curve is => p = 1000 − 4QD(p)
Inverse supply curve is => p = 50 + QS(p)

Solve for equilibirum.

I know we solve by putting them equal to each other, get the equilibrium quantity, plug it into the function again, and get the equilibrium price.

But what the hell are those 4Qd(p) and Qs(p) stuff? Do I take this (p) to the other side and square it? God, I hate this. Please help. I want to punch myself.

Is this a trick question cuz honestly it looks too simple so I'm baffled as to why you're struggling.

It's been a good five or so years since I was taking an micro course though so maybe I'm just missing out on sth

I don't know anything about economics, but the QD(p) and QS(p) are probably Demand and Supply of p. So when p appears inside parentheses, it indicates the usage of p in the Demand and Supply functions, and you wouldn't use (p) in any mathematical operation, like taking it to the other side and squaring it.

The 4 next to the QD(p) in the first equation is a product though, so 4QD(p) is 4 times QD(p).

So if p = 1000 - 4DQ(p) and p = 50 + QS(p), then
1000 - 4DQ(p) = 50 + QS(p), so
950 = QS(p) + 4DQ(p)

I wouldn't know what to do beyond this.

I told you, I hate math and it hates me back. Equally. But if you've studied micro, then you'd prolly know this.

That's the thing, I don't know if it's a trick question or not. I don't know if this uses calculus or not (and the prof said it might use that)..

The topic itself is super simple (Demand and Supply, Price Elasticity). I know them very well in O levels, soe courses in undergrad -- but I never had to use math to solve them, hence the freaking out.

Even for this question, I know the intuition behind it (like I said, put them equal, solve and get the quantity, substitute it back in the equation and get the price). If I do that, my quantity comes to 190, and price 240. But that (p) part at the end is just bugging me. It could just be me being stupid too. Math does that to me.

Have a heart. Don't judge. just halp okay. :mv:mv

Is there any other pertinent information in the question? It seems like with the two equations, you're left with a relation that wouldn't allow you to solve for either QS(p) or QD(p) or p for that matter. I would think the functions QS() and QP() would be provided.

Nope, nothing else required for this part.

We're solving for equilibrium. That's where demand and supply intersect, and become equal, so we assume QD = QS.

So assuming QD = QS = QE (quantity at equilibrium), we put the two equations equal to each other.

I'm sorry I'm bugging you with this at this hour.. It's been a really tough past few weeks.

Oh, so if QD = QS, that's a third equation. So if,

950 = QS(p) + 4QD(p), and
QS(p) = QD(p), then
950 = 5QD(p), and
QD(p) = QS(p) = 190

and if we plug that into either of the first two equations, p = 240

But I guess you're concerned that this seems too easy... maybe it isn't, and those really are the answers?

Guys its an Inverse demand function

its slightly different from the normal demand and supply from what i recall

so you cant do Qd = Qs

just have a refresher on that and youll be fine

i havent done this myself in eons and have a ton of other work to do so sorry cant be of direct help atm as i dont wanna give you a wrong answer but dont follow Nostalgics calculation lol where Qd=Qs

It is introductory level Micro! My Masters program is in International Relations, not Economics - and most people are studying this for the first time! Hence the basic introductory course --

I totally get the whole inverse demand thing. Inverse demand function basically makes price the subject. All I wanted to know was that since the question SAYS that the inverse demand function is => p = 1000 - 4QD(p), what the )**&@^$@_ hell that stupid (p) next to 4QD means here.. :bhatti

And if that dang thing is calculus or not! :bhatti :bhatti :bhatti

Haha, thank god I opted for Macroeconomics as opposed to micro for my basic education elective course. Though, I've heard both are easy. Only thing is, I'm taking Macro online so the slacking is through the roof.

And if that dang thing is calculus or not! :bhatti :bhatti :bhatti

I've asked some people. Let's see what they get. Meanwhile, I'll just go bang my head on the book again :sree 4 more pages of problem sums to go - weee :danish



Don't worry.. It's as good as any.. Thanks still tho.




Next week! This is due Monday :P

Thanks still for all your help - although I gotta wonder how come your life became so boring as to worry about an econ problem like that - one you don't even have to submit? :srt

Dang. I missed these smileys :zia

As far as I know, there shouldn't be any Calculus involved. My younger brother's doing micro and he hasn't even learned Pre-cal let alone Calculus. Have you tried WikiAnswers? Like copy paste the question in Google's search engine? lol.

There's supposedly calculus involved at some point but man, I don't even know.. I honestly just hope I pass (after a whirlwind of craziness in undergrad, I'm done stressing over grades.)

I tried that. Nada :/

Have you learned Calculus at all? Pretty unfair to be asking you to use it if you didn't.

Nope :/

It's a pass/fail thing tho. Let's see how it goes.

Thanks I already knew that :P

Most people I know are solving it exactly as how Nostalgic and I did it here.. so I'm sticking with that :P

Okay guys I need help in Microeconomics (yet another stupid core eco course for my degree).

It's pretty basic stuff, but I'm a dumb dodo when it comes to math and eco.

Inverse demand curve is => p = 1000 − 4QD(p)
Inverse supply curve is => p = 50 + QS(p)

Solve for equilibirum.

I know we solve by putting them equal to each other, get the equilibrium quantity, plug it into the function again, and get the equilibrium price.

But what the hell are those 4Qd(p) and Qs(p) stuff? Do I take this (p) to the other side and square it? God, I hate this. Please help. I want to punch myself.

Inverse demand curve => Demand curve
P = 1000 - 4Qd => Qd = 250 - P/4

Inverse supply curve => Supply curve
P = 50 + Qs => Qs = P - 50

Equilibrium
Qs = Qd
P - 50 = 250 - P/4
P = 240

Qs = 240 - 50 or Qd = 250 - 240/4 = 250 - 60
Qs = 190

Equilibrium occurs at P = 240 and Q = 190
