When I lived in Arizona, I found that the roads were set up much like a Cartesian Coordinate System. This made getting around town very easy, even if I was going to a place that I have never been. Please explain a real life situation in which a similar Cartesian Coordinate System exists, or could be developed. Include why it is or would be beneficial.

if you mean

then it's c. 8, -7/3

but if you mean

then it is

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.

step-by-step explanation:

copy and paste, put it in google

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

d) 48
