Thank you so much Reiny!

wouldn't it be past 1981 instead of in the 6th month of 1951?

Does the .477 years mean the 6th month (June) you were talking about?

I just reposted this again a couple seconds ago. Didn't see you helped me with this. Thanks for you help...

Thank you for your help!!

ok, so i got e^-7 and e^2 does that mean i reject e^-7 because its less than or equal to 0?

So i got g(x)= (4x^2-16x+12)/(x^2-4) is this correct?

Thank you for your help! For the second part I thought it would be -(9+6h-h^2)-6+2h?

(f(3+h)-(f(3-h))/2h I put a minus sign because it has a negative in front of the f(3-h) so it's -(f(3-h))

Oh I just replied again.

I got the following, but I'm not sure if I did it correctly: 2Fe(OH)3 + 3OCl- ->2FeO4-2 + 3Cl- + 4H+ + H2O If someone could let me know whether I solved it correctly or not, that'd be nice. :)

Factor x^2+x+12 now

Thank you so much bobpursley!!!

If your asking the answer to this problem you multiply 6*5=? then divide that by 3

ok here's what my workbook says Circle the letter of the best synonym for the word(s) in bold-faced type. INCUMBENT UPON all officials (incumbent upon is bold-faced.. these are the options a) the parameters of b) the duty of c) the term of office of d) the puissance of e) the demagoguery of i narrowed it down to B and C

THANK YOU SO MUCH!

You can do this on a calculator. for y put x-11 and see if its linear. To evaluate just plug 4 for x so it would read f(4)=4-11=-7

Thank you so much! It makes perfect sense and when I calculated it, it matched up.

Is 3 True? or is the answer 9.80?

i know that the derivative of that is 1/2x^(-1/2) i still don't know what to do

oh wow thank you so much!! that makes sense!!

Thanks for help on 1. on 2. if i do u=sqrt(x) my du is 1/2x^(-1/2) and that means my du is in the denominator. So it would read 2integral of sin(u)/du

Thank you so much!

The options are: 3.549 g 35.49 g 35.49 mg 0.1 g 0.1 mg

It actually depends on account instructions on dropping the 's. Both are correct.

(23kg)(9.8m/s^2)(cos(38)) = 177.6N

There are 144 perfect pumpkins.

These are the calculations I can up with for experiment 1: a:mass of water in the hydrate sample (g) 1.804g b:number of moles of water in the sample 0.100g c:mass of pure salt in the sample (g) 3.196g d:number of moles of salt in the sample .0214g e:molar ratio of water to salt in the sample 4.673g For Experiment 2: a:mass of water in the hydrate sample (g) 2.658g b:number of moles of water in the sample 0.148g c:mass of pure salt in the sample (g) 2.342g d:number of moles of salt in the sample 0.016g e:molar ratio of water to salt in the sample 9.25g I really just need it checked and help with the formulas please!

Formulas for experiment 1: CuSO4*5H2O CuSO4.XH2O --------> CuSO4 + XH2O Formulas for experiment 2: MgCl2·6H2O MgCl2 * X H2O = MgCl2 + X H2O I just need someone to check my answers please :)

idk man

Tylin is right
