To clarify : Consider the Matrix M = (2 0 (on top) and 0 2 (on bottom)) Calculate M^n for n=2,3,4,5,10,20,50. Describe in words any pattern you observe. Use this pattern to find a general expression for the matrix M^n in terms of n.

There are other questions but I would really appreciate it if I could just have help with this one because I don't even know where to begin.

Thank you so much! I didn't even think of using an indentity matrix. I also used the matlab - which was a great help! Thank you again!

595/60 can just be considered a fraction. So you have to simplify it by multiplying both the denominator and the numerator by 5/5. This gives you 119/12 which cannot be reduced anymore. Also 9.91 is 9 91/100 not 91/60.

we are not given the molar mass of the vit. C. how are we supposed to find the milligrams of vit C are in the orginal sample?

13 years ago

to find the total moles of iodine, do you just multiple 8.5x10^-4 by .00660 L?

13 years ago

to find the molarity of the original vit C do you just divide the moles found in 1 divided by 0.001 L or 1.0 mL?

13 years ago

Nevermind. i figure it out. Thank you so much for your help!

would 5.61x10^-5 make sense for the molarity for the original unknown sample of vit C solution prior to dilution?
