To estimate instanenous velocity you need to know the derivative or the slope at the given point. Is there more information on this question.
GIS (global informational system)
GPS (global positioning system)
VGA (Video graphic array)
Remote Sensing (The scanning of earth by satellite to obtain information about it)
So now that we have the definitions down, GIS,GPS,VGA, and Remote sensing provide a better understanding of what is happening at a local or global level by explaining the steps being taking to obtain the information. GIS gathers the information of the region, GPS creates the route of the region, VGA connects the information and routes gathered by GIS and GPS to your cellular device, and Remote sensing may seem like the same concept of GIS however remote sensing uses satellite images of a wider area.
Sorry if this explanation seems long, or seems to not make sense. I'm just learning about this stuff and thought I'd try to answer (:
The answers should be in the reading, that’s why it says, “read the..answer the following questions..answers are in the lesson.”
Take dual enrollment courses,, make sure you search what classes to take for the degree you want tho so you don’t have to waste time. but i think it’s only affective if you start early in your high school years
