Also I needed help finding the electric field at the position of the test charge!

In the above equation(length=t^2 * g/(2PI)^2), what do the symbols ^ and * represent? (Sorry, but this is my first semester back at college after ten years of being a stay-at-home mom, so I'm VERY rusty on a lot of areas.)

Go to View, Header and Footer, there will be a box for Footer, type in what you want there, and press Apply, or Apply All if you want the footer on every sheet.

How did you get this answer I have been pondering over it for 2 days. You are a genius. Thanks

Net income is the difference between revenues and expenses when revenues exceed expenses for a specific time period.

My answer is domain(all real numbers) range(all real numbers) Is this right??????????????

I think I have an answer to both the first and second problem. Problem 1-It appears you are subtracting 8 each time. 64-8=56 56-8=48 48-8=40 40-8=32 64,56,48,40,32 Problem 2-It appears you are adding 5 each time. 61+5=66 66+6=71 71+5=76 76+5=81 61,66,71,76,81

I still don't quite get how you are explaining it. Can you explain in a different way?

An understood pronoun is when you talk to someone but leave out the word "you", because its obvious that you are talking to them. Example: "You pick that up" could be said as "Pick that up" In the second sentence the "you" is unserstood, so it doesnt need to be said.

I understand how you do it for T, but since there is more than one J, I don't understand how you make J the subject.

FYI: AS i mentioned before. I DID SEARCH THE INTERNET. i FOUND TWO DEFs. I WAS ASKING FOR CLARIFICATION =)

I am not sure about the equation either. Obviously if I2 was being produced in the titration then the end point could be tested with starch, but the compounds I have found seem to be right according to the percentages, so I'm not sure what else the equation could be.

Make a substitution. Let x = cos2t(theta) and you'll have 2x^2 + x-1 = 0 Then factor: (2x -1)(x +1)=0 x = 1/2 or x = -1 so cost = 1/2 or cost = -1 t = 60 degrees, 120 degrees or t = 180 degrees. In the second one, let cotx = 0 and cscx = 1/2 and now solve for the values that make those equations true.

Thank you GuruBlue and Ms. Sue!

So then the final answer is (m+4)(2a - 2)

In solution it would separate into ions. As this is a strong base it would be fully dissociated in solution i.e K+ ions and OH- ions.

Thanks!

ok based on that I would say the radius is 8 cause 8*8 = 64 and the center is (1,5)? Or do the signs change because of the equation (x-h)^2 + (y-k)^2 = r^2 making the center (-1,5)?

That is what I thought, so the standard form would be (x-(-1]^2 + (y-5)^2 = 64

Great! Thanks for the help! So R= 8 and the center is (-1,5) got it! Thanks again!

so based on this her sales would be $740.16 money earned from weekly sales +225.00 base pay $965.16 Amy’s Weekly Paycheck Earnings

Thank you for the help!

I think I got it! Are the slopes of the given and parallel lines = ?

f(-5)= 1^3 +5(1)^2-3(1)-15 = -12. f(sqrt3) = 1^3 +5(1)^2-3(1)-15 = -12 f(sqrt-3) = 1^3 +5(1)^2-3(1)-15 = -12 Are these correct?

What is r2 and r3 stand for? Not too sure how to check this. Can you show me please I got 10 more problems like this. Thanks!

Ok so the function is f(x)=k(x-r1)(x-r2)(x-r3) =k(x-(-5))(x-ã3)(x--ã3) Now to check this?

Thank you! I will check that out!

The question is what do they do not to feel guilty? They should feel guilty, but some people don't. Is there a logical answer to this question? Thanks!

So to keep from feeling guilty they use a scapegoat or excuse?

Ah well first of all the person who goes to prison is found guilty of a crime. The hitting someone occurence could happen for any stupid reason. Your thoughts? How can I logically answer this question? If people feel that they must hurt or harm a person, what do the people do to keep from feeling guilty about hurting that person?

Thanks for your insight to this question!

I believe the answer to part (B) can be found in your text in the chapter on Acid Rain. It that chapter, it states that Carbonic Acid acts in the environment to keep rainwater at a pH of between 5 and 7. It then goes on to dicuss the term acid rain as pertaining to precipitation that has a pH lower than 5. Sulfur dioxide contributes to acid rain, the result of pollutants, as it absorbed into the atmosphere and reacts with water, becoming sulfuric acid. Sulfuric acid, in the form of acid rain is responsible for the formation of large caves and other natural features but it is also responsible for billions of dollars of corrosive damage to metal, paint, stone and other exposed substances. It also causes a great deal of damage to the envorionment. So, without knowing anything about the chemical structure... if you've read about acid rain, you'd be able to answer the question.

yes it is just posted the class for it. HCR/230 - CLAIMS PREPARATION II: FOOTING THE BILLS (AXIA)

20.45 mph solution: 30ft X 1 mi X 60 S X 60 min = 108000 108000/ (1s X 5280 ft X 1 min X 1hr) = 20.45 mph

Do you think this would be an appropriate answer to the question? Specialist vocabulary is necessary under certain circumstances in order to communicate among people who understand and are expected to because of their profession.

Thanks for your help!

Count the sides.Or check the size

Alkanes have weaker intermolecular forces than alcohols because they have no hydrogen bonding, only dispersion forces.

The answer is D. The sqrt of 16 is 4. The sqrt of 4 is 2.And just keep the sqrt of (2) the same.(:

64.93 You do pythagorean theorem. a2+b2=c2

Thank you. On the second one I forgot to put an O--CH3 over the CH O--CH3 CH3--CH2--CH--CH2--CH3 ___________________ Does anyone know the functional group of the following? Thank you. OH CH3 CH3--C--CH2--CH--CH3 CH3

Ok, it looks good then? Thank you for looking it over. Do you know where I would be able to receive online assistance with drawing structures? Thank you.

yes, it is tetrahydrocannabinol. I had put because OH is acidic it would be an example of an aromatic alcohol.slightly acidic. also phenol and carbonic acid. Thank you for letting me know it is only an ether and a phenol.

I do not have any table of functional groups. I am out of the city w/o a textbook visiting an ill parent. I will look online. I think I have it though regarding functional group. Any OH-C bond is an alcohol. O would be ether due to C-0-C bond. C-SH bond would be thiol. But I still really need assistance with drawing structures.So no online help for that it looks like...

Ah, I see what you are talking about. OCH3 is above the CH ________________________ OH O is above the CH Also OH is under the CH ________________________ OH is under the C ___________________ CH3 O is above the CH ____________________ Br is above the C OH is under the C _____________________________________ any help is appreciated. If it is four groups, then wouldn't all be chiral carbons?

How did you get that?

not sure about the question but maybe 9990 1 and 9990 5 and 1998 10 and 999 sorry if this was the wrong idea

-243/20 there is nothing more simple than that unless it's a decimal

Thanks!I get it now. Getting 250 mL just confused me because it was more than I started with, but that's what I want, just in a weaker concentration, right?

No, I'm having trouble figuring the molecular weight of it so I can then figure the molarity.

I have not idea how to work this problem without the grams or the ML of the solution!

WOW, Great Explication!!!

thanks

Thank you for all your explanations-it really helped alot

THANKS:)

Oh ok, thanks!

nvm i got it thanks anyways:)

wait.. im now stumped on this one Calculate the pH of each of the following solutions. [OH - ] = 1.1 10-11 M

I don't understand how we can know the total moles of solution if the question doesn't specify what the aqueous solution is. Do we always assume its water??

Thanks :)

need derivative

Thank you!

Revolve the region bounded by y = 4x and y = x2 about the y-axis. In cubic units, the resulting volume is

A cricket produces 116 chirps per minute at 72 degrees Fahrenheit and 177 chirps per minute at 80 degrees Fahrenheit. Find a linear equation that models the temperature as a function of the number of chirps per minute .

The following system is at equilibrium with [N2O4] = 0.55 M and [NO2] = 0.25 M. If an additional 0.10 M NO2 is added to the reaction mixture with no change in volume, what will be the new equilibrium concentration of N2O4? N2O4(g) 2 NO2(g)

Molarity = mol/ L = 0.0025 / 0.00368 L = .679 M

Thank you so much for your help! I was able to follow your steps very well! Much appreciated DrBob222!

this is so helpful!

So 34.2/14.6?

Thank you. i sort of had to back track to get the answer you got but eventually got it. Thank you!!

Thanks It deffinatly helped some. I also realised I was downsizing the number to much.

Interesting. Im glad I wasn't to far off on the answer. Makes me feel a little better about everything. Thank you so much!!!

You were right, the answer was A, thank you!

Thanks :)

Yeah you're right! I got that as well Thanks!

Can you do other sentences for me as well?

1 Domini fili utit dare pecuniam 2 Laudabimus , enim (their) famae est magna. 3 Iuvabone aegrae feminam? 4 Nunti,(news) ad nautam nunc 5 Diu, regina non optabat dare regnam ad filiam 6 Orabunt deum magnae sapientiae et laetae vitae 7 Pueri et puella, tacete et vocabo populus fabulam novam

Just one but the I thought the I was for the genitive case or it would just be filius?

Thanks for the help :)

The other two parts are: 1) How many carbon atoms are there in one of these pills (due to the presence of ethinyl estradiol)? 2What mass of carbon is this? (Enter the answer in grams.)

Thanks :)

Is the answer Tropical Forests?

is my answer correct?

Pastoralism is the branch of agriculture concerned with the raising of livestock. It is animal husbandry: the care, tending and use of animals such as camels, goats, cattle, yaks, llamas, and sheep. so the answer is grasslands?

Mrs. Sue the answer should be deserts least likely

Thank you Ms. Sue

How?

Thank you, again.

Thank you for helping me FIND the answer, and not just giving it to me. That's very wise of you, and helpful to me as a student who needs to be capable of research.

Um.. Not sure.. It's not d, probably not a.. Is it b? That sounds most logical..

Who are the parties involved in this joint study? : It would be NASA and the International Space Station, right...?

thankssss

I need help with crossmatics puzzle 7

Yes, had just finished getting it! Thanks!

Take 9,850 and multiply it by 6.2% you will get 610.70. then multiply 9,850 by 1.45% you will get 142.825. Add together the 610.60 + 142.825= 753.53 is the total that is withheld from Dans check.

no i did not

I did sorry about that but I have found the answer since then. I got it wrong when I submitted it but time was running out. However, I know the answer now but I still don't understand it at all.

Yeahp rosco

B D A B B Just took the test. got 3/5
