Awater balloon is thrown out of a window 96 feet above the ground. the balloon is traveling downward at 16 feet per second initially. if h is the balloon’s height in feet after t seconds, then h = -16t 2 -16t + 96, it will take the balloon blank seconds to hit the ground.

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?
