A right triangle has side lengths ,5 ,12 and 13 as shown below. Use these lengths to find cosL, sinL, tanL and .

Write a function that matches the description. a cosine function has a maximum of 5 and a minimum value of -5. f (r) =

What are the coordinates of the point that is 1/3 of the way from a to b? a (2,-3) b (2,6)

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?
