Q:I'm an aspiring artist and think that cutting gemstones would be really cool and fun. Are there any non-expensive tools that I could use to get a feel for the art? I looked online for awhile, and it seems the only way is to grind gems is on a grinding wheel, and that freaks me out somewhat ;-) . Also, what gems would you recommend for my first try? Any help is appreciated! Thanks!

You could, in theory, get carborundum grit (or diamond grit for some stones) and a steel or iron plate and mount the raw stone on a handle (dap stick with dapping wax) and push it back and forth to facet it. You might get one done in a year or so. Go and learn about lapidary and the tools for handling precious and semi-precious minerals.

I believe you have to get the machinery past customs and you have to get import paperwork done.

Q:A certain piece of machinery was purchased 5 yr ago by Garland Mills for $470,000. Its present resale value is $280,000. Assuming that the machine's resale value decreases exponentially, what will it be 3 yr from now? $___________.thanks

Sine the price decreases exponentially, we can model this with: A = P*e^(kt). Since the initial value is $470k, we have P = 470000 and so the equation becomes: A = 470000e^(kt). Since the value 5 years after purchasing it is $280k, we have: 280000 = 470000*e^(5k) == e^(5k) = 28/47 == 5k = ln(28/47) == k = ln(28/47)/5 ≈ -0.1035886. Thus, the price after t years is 470000e^(-0.1035886t) and so the price 3 years later (8 years after buying) is: A = 470000e^[(-0.1035886)(8)] ≈ $205,208. I hope this helps!

Q:I have an assignement where I have to explain how ribosomes in plant cells are equivalent to a machinery in a city.I understand the concept and the general idea, but I don't know how to word it out and explain it clearly.Any ideas?Thanks!

ribos keep the body moving and working, just like machinery in a city. it takes the garbage truck picking up the trash, delivery trucks bringing in fresh produce, police cars keeping the peace, construction machinery building new structures and so on so the city continues to function as a whole. when one piece of machinery breaks down it causes a chain reaction that affects thru out the city. same goes for your mind and body. good luck
