Oh! I see now, thanks very much.

Oh, okay. I got it. Thanks!

Ok, now I have to use the derivative and solve for P. So, the equation is: 4 = -200P^-3 I can get it down to: -50 = P^-3 But, I don't know how to get the -3 away from the P.

2.) Multiply the first equation by 4 and the second equation by -3. 4(2x - 3y = 8), so 8x - 12y = 32 -3(7x - 4y = 11), so -21x + 12y = -33 So, the first equation has -12y and the second equation has 12y, so the y variables cancel out.

What do u mean? ive been reading up on it and cant find anything that relates between them not the charge or anything so i don't get this questiong and plus how would I know how it arose historically. . .

Ok found the histroy but I don't see how it relates to the charge of an electron. . . or how ahhhhh.

-The ruling of “separate but equal” facilities being constitutional in America in the “Plessy vs. Ferguson” case was one of the worst rulings the Supreme Court’s could have made because it led the pathway for the Southern society to become economically unsound, morally unjust, and the decision still scars the American society of today.

Sorry about the grammar error above. Its from me changing it so many times.

i got 1. c 2. b 3. e 4. f 5. a 6. d

i got 1. c 2. b 3. e 4. f 5. a 6. d are these right?

i got 1.39 and -4.06 but i still got it wrong

The experiment is "analysis of a complex iron salt" . We had a previous lab in which we prepared a complex iron salt and then left it in a dark locker for a week to crystallize. For this upcoming lab, we are weighing .1 g of the complex iron salt and dissolving it and then heating it then titrating it.

thanks.

The Holy Sonnet was written by John Donne. On 6, I still don't see any of those being the answer.

5(2x-7)<-8 10x -25< -8 10x< 17 x<(17/10) x<1.7 I think you only change the sign when you move a negative by multiplication or division, so I think the sign is correct. You might want to reference your book though.

ah, typo, sorry. 5(2x-7)<-8 10x-35<-8 10x<27 x<2.7

no its that i am confused about the question and which part to focus on

thank you but i need help with the other question please

ok sorry but can someone please help me with the other question

should i have a body phargraph discussing how it can be accelerated evolution and how it can be a cataclysmic revolution or should but that in the other 4 body phargraphs

if i decide it is accelerated evolution do i have to mention how it could be considered cataclysmic revolution

i meant with other elements

how about this? I trust that this program will help me elaborate my ideas pertaining to the future of Washington. I wish to study Law and Political Science to eventually become some kind of activist, whether it is lobbying, or advocating in some small part-time organization that pertains to any of the topics discussed before: environmental, worldly, and philanthropic deeds.

Thanks! Can you help me out again? ...encouraged me to spread awareness about current issues especially to Washington high schools; students need to be informed about the issues in their own state. Presently, many of them are blatantly oblivious to current events, for example, when I asked one student who he wanted to be President, he replied “Obama, because McCain is too old.” Obviously, this student has no clue about the political platforms of both candidates; many other students are similar. I need help ending a paragraphh im on a word limit- so i need help condensing also (: thanks!!

Thank you very much for your help.

English is my second language.

Midpoint formula

The book has the correct answer at -4..how'd they arrive at that?

got all that need more

thanx

i don't get the first equation explain more please

should i be using the equation you wrote for finding the net EXTERNAL force??

i got 1366.8 N and i'm asked to round to SF would it be 1.3*10^2?

i corrected it and i got 683.4 N, does that sounds right? if yes, would it be 6.8E-1?

I was confused on the structure could someone write me the condensed formula for this compound thanks.

nvm i got it figured lol

DrBob222- I didn't get any answers from you? I looked but didn't see anything. Can you redo it maybe? Please and Thank You!

Thank you.

i do know that but i don't know what makes it possible for a stem to give rise to roots. I'm taking plant Biology

i think it wouldn't matter that they have different masses, both will have the same kinetic energy energy. and they will have the same height. and i think C) too is correct but i'm not sure could some one tell me if i'm right or wrong? i know it will not be A) or D)

Thanks that really cleared it up! :)

they are indeed both math questions. I know very strange! Can anyone else confirm they are both true? Thanks.

thanks!

thank you.

okay but how can i tell if the cost of living oversea(Europe) is less or more than the USA, how would that be fair to the employee?

Okay thanks, I will compare the cost of living for France & USA. Thank you

Thank you very much Ms. Sue

thanks Sra

I got the answer as 1E-7, but it wouldn't accept the answer, any ideas?

water will rush into the blood cells causing them to become hypotonic, swell, and possibly rupture.

i figured it out...nvm

4.32g C X (1/Molar Mass C)X (3 mol TiO2/ 4mol C) X (1 MOL/ Molar Mass TiO2)

whats the distance from the center of the earth?

this is correct

If one wants to know how the material well-being of the average person has changed over time in a given country, one should look at the? A. level of real GDP. B. growth rate of nominal GDP. C. growth rate of real GDP. D growth rate of real GDP per person?

thank you so much for the clear explanation. i really understand how to do the problem now! i appreciate it!

im not very clear on the steps of newton's method because my professor didn't explain it very well. Do you just take the second derivative of y and then plug in -1.25 to find x3. I don't quite understand the concept...thanks for the help in advance.

I am not sure what you are saying!What would the formula be! thanks

i think I got it. Thank you!

I think it would be a base because like you said it has no space to accept any electrons. As, for the other compounds is this correct: O2- is a lewis base Cu2+ is a lewis base AlCl3 is an acid SO3 is an acid ????

2.7 × 10-4

What did u you get as the answer.. i have a feeling mine is wrong

my answer was wrong.. I got 4048.47? What did you get?

I can't divide out the v's and I know you are solving for "v".. but I can't seem to finish it out.. I got... 8.1v^2=mg+mv^2/r Then 8.1v^2=g + v^2/.45 then I don't know what to do from there

1. I'm not sure 2. "no reaction" 3. 2HBr(aq)+Sn(s) --> SnBr2(aq)+H2(g) 4. "no reaction" 5. "no reaction"

thank you mr.pursley

Thanks For Nothing :)

How do you figure miles per hour?

I meant meters per second

Well I'm trying to figure out the chemical equation

I think it is looking for a vocab word but not sure What do you think

Melissa you should probably just ask Mr Earls because apparently anyone doing the question has no idea what to do

Oh I see thank you but the new bounds after you have changed the order shouldn't it be x= log(y)to 4 --> because I rearranged the bounds from y=e^x to x=log(y)?

PH= 4.56, PKa= 4.74 PH = pka +log(Base/Acid) -0.18 = log(Base/0.200) B = 0.1321 M >>>> o.1321 mol/L Molocular weight of acetic acid = 82.03 g (0.1321 mol/L)(0.4 l) 0.05284 mol (0.05284 mol)(82.03 g/ mol) = 4.33 g. I hope this helps!

Awesome thank you :)

2m*sin(45)= length of fall (LOF) this needs to be plugged into equation henry posted. The suitcase does not fall 2m unimpeded. It slides down the ramp at 45 degrees. Thus trig is needed to solve.

Thanks!

don't I need to put it in y= formula first?

Sorry didn't see Reiny's post

I'm not sure I will look over my notes to see what I come up with.

thanks for the help

Is the answer (x-2)^2+(y-1)^2=40

um i think u wrote H and/or J wrongly but its either H/J.. u wrote the answer wrongly fully hope it helps

log3 (x^2-4) -log3 (x+2)=2 log3 [(x^2-4)/x+2)] = 2 log3 [(x+2)(x-2)/(x+2)] = 2 log3 (x-2) = 2 x-2 = 3^2 x = 11

B= 180 - 87 B= 93 degrees.. :)

Ok daddy :)

11.54?

N*p/100 good luck mate

adjust ur scale and use E-ve numbers try using ln instead of logs dont be afriad to start ur graph later...instead of at 0 or 1

sXq 3.97 is lengith

x= 7

pay me 25$ and i will do it

10 times

I think its either A or B but im not sure cause when i multiply 1/6 and 567.00 and 4 i get 378.00 but when i multiply 567.00 and 4 and divide that by 1/6 i get 13,608.00

always true

Thank you, How would I calculate acceleration and magnitude once the ball is cut?
