The function c(w)=0.013w^2-w-7 estimates the wind chill temperature c(w) at 0 degrees f for wind speeds w from 5 to 30 mile per hour. estimate the wind chill temperature at 0 degrees f if the wind speed is 20 miles per hour.

60 2(x + 2) in the diagram, gef and hef are congruent. what is the value of x?

In the diagram, points d and e are marked by drawing arcs of equal size centered at b such that the arcs intersect ba and bc. then, intersecting arcs of equal size are drawn centered at points d and e. point p is located at the intersection of these arcs. based on this construction, m , and m
