S= 4000x + 53000

Where S is measured in dollars, and x is measured in years and x=0corresponds to the year 1998. Find the predicted sales in 2006,assuming this trend continues.

Parametrize the surface S. S is the portion of the cone (x^2/25)+(y^2/25)=(z^2/25) that lies between z=5 and z=7

5.33 Each of the following reactions has been described in the chemical literature and involves an organic reactant somewhat more complex than those we have encountered so far. Nevertheless, on the basis of the topics covered in this chapter, you should be able to write the structure of the principal organic product of each reaction.

I need help with this problem. Can you help me set it up? Suppose you want to make a scale model of a hydrogen atom. For the nucleus you choose a small ball bearing with a radius of 1.4 mm. The radius of the hydrogen atom is 0.529�10^(?10) m and the radius of the nucleus is 1.2�10^(?15) m. What would be the radius of the model in m units?

Roughly speaking, the radius of an atom is about  10,000 times greater than that of its nucleus. If an atom were magnified so that the radius of its nucleus  became 2.0 cm, about the size of a marble, what would  be the radius of the atom in miles? (1 mi 5 1609 m.)
