4th grade math
Hi! This question says Joe is thinking of o function machine.He says that the output is 12 if the input is 4.what are 2 rules that he could be thinking of for his function machine?( I would really be grateful if you helped me) ;)thanks
Physics
Five forces act on an object. (1) 63 N at 90° (2) 40 N at 0° (3) 83 N at 270° (4) 40 N at 180° (5) 50 N at 60° What are the magnitude and direction of a sixth force that would produce equilibrium?

how do u find the standard numeral for 9.3x10^-4
Chemistry
how would you sent up aluminum carbonate --> aluminum oxide + carbon dioxide. im guessing AlCo3 --> AlO3+Co2 but i dont think thats right
Chemistry
Write skeleton equations for these reactions. a. butane(l) + oxygen (g) --> carbon dioxide(g) + water(l). b. aluminum carbonate(s)--> aluminum oxide(s) + carbon dioxide(g) c. silver nitrate(aq) + sodium sulfide(aq) --> silver sulfide(s) + sodium nitrate(aq) d. iron(s)...
Chemistry
okay im getting closer(: so would nicket(II) oxide be NiO2 and dichlrine pentoxide be Cl2O5
Chemistry
okay im sure i can get one right soon. now if it has a polyatomic in the equation like Tin(IV) nitrate would it be SnNO3? and if it produces iron(III)nitrate would it be Fe(NO3)3
Chemistry
sorry but i want to make sure im doing this right. for lithium+gold(III chloride-->lithium chloride+gold would it be Li+AuCl2-->LiCl2+Au?
