No thay said some of these i have to look up their names since i don't konw really SO3 means i think Sulfuric Oxide

i don't get it what do you mean not science it is please find a website for me

can you also help me out on the other ones please i don't have a clue on a website

it only has a few

Well look were suppose to classyfy chemical equations which is the main point were doing then she wants us to name their name which that part im having a hard time and im not getting a tutor since i get straight A on all my classes

1) N=8 / I%=28 / PV=1.25 therefore FV = 9.008 2) 9.008 x 1.06 = 9.54848 3) 9.54848 / (.13-.06) = 136.41 4) N=8 / I%=13 / FV= 136.41 therefore PV = 51.31

5) PV of Growing Annuity (From t=0 to infinity) = 18.25 6) 51.31 + 18.25 = 69.56

B) it would be 26P4 (the number of permutations for the letters) x 9P3 (number of permutations for the digits) You times because for each letter permutation the can be 9P3 digit permutations.

Is posible that you put all the procedure step by step?, thank!!!!

shut up ms sue your no help at all all we want is answers

can you guys stop fighting i am the one is right

Well I calculate for my self but I don't sure???? They give me a formula Fdrad= 1/2PxV^2xCdxA and P=FdragxV for converting that in HP = Px(1hp/550 ft lbf/sec) ok. Fdrag=1/2 (0.0019)×(587)^2×0.398×26.72 Fdrag= 3,481.12272 slugft/sec^2 P=Fdrag×V P=2,043,418...

If that is the answer I hop help some body!!!!!!

Well 1. transform to angular velocity w=(3.75/11)=0.34.... because (w=velocity/radious) For definition of centripetal acceleration is like: a=r*w^2 replacing we have a=(11)*(0.34)^2=1.27m/s^2

Thank u key girl I got 100

Give us all the answers

SO MF'S HOW YA DOIN?
