d=rt Distance=Rate (Speed) x Time This equation can be used to find Distance, Rate, and Time.
The half angle formula is used to calculate chord length in circles. This is particularly helpful in complex construction projects involving curves. It's not like you'll be doing this if you're in marketing, selling insurance, or are holding down the sous-chef de cuisine slot at a five star hotel. But it's real enough to those who work with this in engineering.

Parabolas are used in real life in light reflectors on cars to create a concentrated beam of intense light. Braking distance and stopping distance are quadratic formulas so their graphs are parabolas. A ball in motion in space has a path of a parabola.
Scale
Somewhere on a map there will be a scale. The scale will tell you the ratio of a distance on the map to the corresponding distance on the ground. eg 1cm = 10km
