Hyun Woo is riding a ferris wheel. H(t) models his height (in m) above the ground, t seconds after the

ride starts. Here, t is entered in radians.

H(t) = -10 cos(2Pi/150 t)+10

When does Hyun Woo first reach a height of 16 m?

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?
