The population density D (in people/mi2) in a large city is related to the distance x (in 5000x
miles) from the center of the city by D =
x2+36
a) What eventually happens to the density?
b) In what areas of the city does the population density exceed 400 people/mi??

people went from manufacturing one object at a time by hand to manufacturing many objects in factories

angle addition postulate

2x=56

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
