Write the equation g(x) = -2x^2+8x-11 in the form f(x)=a(x-h)^2+k

The quadratic function h(t)=-16.1t^2+150 choose the graph representation

What is the simplified form of (3.25x10^3)(7.8x10^6) written in scientific notation?

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?
