We have all read about evolution, but how does something that is not living pop into existence having a fairly complex strand of DNA or RNA in it for no other purpose but being a transport device to infect another individual? Is it possible that they were created by someone?

Problem: Last year, Kirsten read one fourth as many biographies as mysteries and eighteen more science fiction books than biographies. The number of Nature books that she read was one less than the difference between the number of mysteries and the number of biographies. If Kirsten read four times as many science fiction books as Nature books, how many books did she read in all?

Suppose that you are in the vacuum very far from everything, so gravity doesn't affects you so much. You are with a friend, and both of you has a digital clock. Both of you decide to coordinate the clocks. Then both of you decide to "travel" with a constant velocity and then come back to were you were, to compare the clocks. In your point of view, your friend's cloks is late compared to yours, and your friend has the same feeling, in his case it's your clock that is late. So when you come back to see the clocks, which is really late?

The cost in dollars to print n copies of a magazine is given by the formula, C=-0.000025n^2 + 0.325n

a) Find the average rate of the cost of printing the magazine using the interval from 100 copies to 200 copies.

i try this for part a -

C(100)= -0.000025(100)^2 + 0.325(100)
= -0.25+32.5
= 32.25

c(200) = -0.000025(200)^2 + 0.325(200)
= -1 + 65= 64

so then I try this

64- 32.25/ 200-100

but the answers says---- $.25/copy how do they get this

b) Find the average rate of the cot of rnting the magazine using the interval from 200 copies to 300 copies.

answer = $.20/copy

What is the marginal cost( the cost of printing one extra copy)
after 100 papers have been printed? ( the cost of printing the 101 st copy. answer= $.27

Wondering why is it harder for females to be clone. Also wondering after 5 years of a clone life it dies. Has anyone hear of a clone living longer than 5years? I know that we eat clone meat,and the FDA hides it from the public. Could that be the reason for most of the health problems of today? Thank you. Take care.
