MODELING REAL LIFE An obstacle course
needs :
new piece made
in the shape
of a triangular prism
with an equilateral triangle for base. The side length
x (in feet) of the base and
prism are related by
the height y (in feet) of the
the inequality y > 1/2x^2+ 1. The
piece has the following additional constraints.
The height must be no more than 7 feet greater than
the side length of the base.
The side length of the base must be at least foot.
Write and graph a system that represents the situation.
Give one example of a height and side length that the
obstacle course can use.
