Suppose the demand function for a product is given by p = 1/3 ln(5000-q/q+1)
where p is in hundreds of dollars and q is the number of tons.
(a)
What is the elasticity of demand when the quantity demanded is 5 tons and the price is $224? (Round your answer to one decimal place.)

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number?

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
