The spinner of the compass is two congruent isosceles triangles connected by their bases as shown in the diagram. the base of each of these triangles is 2 centimeters and the legs are 5 centimeters.
if the metal used to construct the spinner costs $13.25 per square centimeter, how much will it cost to make this part of the compass? round to the nearest cent.
cost =

Write the equation for the parabola that has x− intercepts (−2,0) and (4,0) and y− intercept (0,4).

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?
