**Chemistry**

E is correct. As we have four bondings, and no one is in any way to be preferred, it is logical that they are sp³ hybridized.

**Chemistry 120**

You will have to calculate the numbers of oxidations in order to prove this to be a REDOX-reaction... The rest is simple algebra.
*Wednesday, February 10, 2010 at 10:06am by dongo*

**geometry**

Well, by a simple vector calculation in the plane, you can easily find the last verticle. However, I interpret the question just as MathMate did.

**trig**

Would also be a possibility, however, it does depend on the scale, as you surely know. If we set pi ^= 3, it is clear what is meant and the recipient can easily calculate how the function looks like in real.

**Math**

Pretty easy. Use the fact that the product of the first derivatives of linear functions and their perpendiculars respectively are always -1. This is: m'=-1/(1/2)=-2 Since we can choose an arbitrary function with the imposed properties, it suffices to take g(x)=-2*x q.e.d.

**Managerial Economics**

A so-called cubic function is nothing else than a polynomial function of degree 3. f(x)=ax^3+bx^2+cx+d, where a,b,c,d are fixed, but not determined constant coefficients, imposed the condition a != 0.
*Tuesday, February 9, 2010 at 8:01am by dongo*

**GEOLOGY**

Well, try to think logically? What is granite? A mineral, and when are minerals form chemically? Yes, when there is a big pressure and a big heat to catalyse the reactions. Hence it is self-evident that the necessary event needs to be the "volcano eruption".

**college math**

hello dongo. First of all thank you but I'm sorry I can't understand it because the question is from my older sister who has a Flu right now and she ask me to post it on the internet so somebody can answer it. Can you solve it for her? please? She will be very very thankful to...

**Algebra**

If inequality sign is referring to simply < or >, then the answer has to be no. This is even an axiom, i.e. one of the most fundamental concepts on which the whole building of math is built on. This implies our unability to prove the spoken-of axiom - it is a definition.

**Physics and Calculus**

Firstly, you are to use not the product rule, but the quotient rule, check out the related wikipedia article. Secondly, there is no necessity to "get rid" of R. Your solution can depend on R, for example. Just treat R as a constant (In fact it is, Radius (R) = 2.7 times 10^(-1...

**trig**

Plot the graphs. It is equal to sin(x). Proof: cot(x), tan(x) have period pi and no amplitude in the classical way. cos(0)=1, hence it cannot pass through the origin, whereas sin(0) = 0, yielding sin(x) to be the function-in-question.

There's absolutely no use in doing so. Even though she's ill, I am really convinced about her managing to solve this, supplied with the correct algorithms. (In fact, I do ot understand why it is always about calculating. Proving the applicability of this algorithm would be way...

**college physics**

A = a*(-1, 0)^T B = b*(cos(27°), sin(27°))^T C = 27*(cos(39°), -sin(29°))^T By using the identity imposed on us by the task, we immediately obtain the result by solving the emerging L.E.S..

**trig**

You have to calculae the limits. As x -> + infinity, we see that f(x) -> infinity as well. As x-> - infinity, one has f(x) -> 3. Hence, the asymptote is 3

**math**

O.K., this is a rather stupid question. A possible tuple of numbers would be (6;6;6;..;6), where there are 12 times this 6. However, this does not constitute a "set" concerning the rigorous mathematical definition of a set. Go and ask your math teacher to read a proper book on...

**11th grade economics**

When granting credits to enterprises, banks will want to have s.th. in return. This is called interest as well. Inflation might also be a trigger for an increasing interest rate, however, it is surely not the main attractor for banks. Banks themselves constitute enterprises as...

**algebra**

Let x denote the width of the rectangle, measured in ft.. The height h is by virtue of the assignment defined as h(x)= 2*x+3. Again, the measurement's unit is ft.. The area of a rectangle is calculated by: Area(h, x) = h*x Substituting h=h(x)=2*x+3, we obtain the final result...

**maths**

Well, I really do not get what precisely you're supposed to do. If you shall find a term of a function on whose graph the aforementioned points are located, you will have to make a LES (linear equation system). y = ax^4+bx^3+cx^2+dx+e Since 5 points are given, it is somewhat ...

Is this really college algebra? However, suppose you take a car and assign it the value x, for instance, beacuse of it being the xth car you encounter on the street. Suppose you've looked up any setting of its. It is called y (u), where the (u) shall denote the unit of the ...

**chemistry**

This is avery good question! This leads us directly into quantum mechanics, a branch of modern physics. It has been proven mathematically (very complex, so I will not bother you with the details!) that electrons can and must be assigned a number, either +1 or -1 denoting the ...

You know the value of expectation, 7.8h, you know the deviation, 0.75h and you know that the amount of students, sleeping more LESS than (or equal) 9 hours is: /bigPhi((9h-7.8h)/0.75h)= /bigPhi(1.6) Hence the required probability to find such a student (sleeping MORE than 9 ...

**11th grade economics**

dongo is right, but I thought I would add this to it: 1)Banks don't get interest; they give it to businesses and the general public because the infaltion rate exists. Banks can only get the interest payments that businesses make after they get loans. Besides that interest, ...

Well, even though I have no experience in this kind of math, i'd say it is not about factoring into prime numbers. To be honest that was actually the first thing I'v though as well. Besides, what is Incan basketball actually? I suppose it is about numbers written in the form: ...

**Maths**

This an easy deal when recalling the fundamental identity for traingles, namely that the sum of the three angles must be identically 180 degrees. (Why precisely 180°?) This means: (x-25) + (2x+40) + 30 = 180 This can be simplified to: 3x + 45 = 180 Subtracting 45 on both sides...

This is something I'd be interested in as well. What presicely energy is isn't clear so far. Scientists are argueing about this. So your science teacher is asking a rather ridiculous question, you can tell that. However, the idea supposed to be used here is the concept of heat...
