Yeah I should know this ... anyway, it's in scientific notation.

1. (3.65 x 10^5 g.)(3.4 x 10^-3 g.) = ? (Don't forget significant figures ... yeah ... )

2. (4.9 x 10^3 g.)(1/3.5 x 10^-3 mL./g.) = ? (Remember it's grams times milliliters/grams.)

Number two, the second parantheses is one over three point five times ten to the negative three, if that makes sense. Thanks! :D

A company's revenue from car sales, C (in thousands of dollars), is a function of advetising expenditure, a, in thousands of dollars, so C=ƒ(a).

(a) What does the statement ƒ'(100)=2 mean in practical terms? How about ƒ'(100)=0.5?

(b) Suppose the company plans to spend about $100,000 on advertising. If ƒ'(100)=2, should the company spend more or less than $100,000 on advertising? What if ƒ'(100)=0.5?

Help, especially with (b)! Thank you!

Show that the equation of the line having x-intercept 'a' and y-intercept 'b' is 'bx + ay = ab'?

That's all it says, and its only a worksheet, not out of my textbook. So I really don't know what is being asked. Any help would be appreciated!
