Jerimoth Hill is the highest point of elevation in Rhode Island. It is 812 feet above sea level and lies at about 42° north latitude and 72° west longitude. What ordered triple represents the location of Jerimoth Hill?
A.

B.

(42°, –72°, 812)

C.

(–72°, 42°, 812)

D.

(–72°, 42°, –812)

Answer 1

A point (x, y, z)
x represents the latitude in degrees
y represents the longitude in degrees
z represents the elevation in feet above or below sea level
now we have :
Jerimoth Hill
42° north latitude
72° west longitude
812 feet above sea level
so the coordinate may be written
( +42, +72, +812)
the (x,y,z) referential may be a "direct" referential
using the three first finger of the right hand
thumb for x positive towards the north
y positive towards the west and z positive upwards.
