Write an inequality to describe the region. The solid upper hemisphere of the sphere of radius 5 centered at the origin
dusya [7]

Answer:

x^2 + y^2 + z^2 \le 25 for z \ge 0

Step-by-step explanation:

Given

r = 5 --- radius

Required

Determine the inequality of the region

The inequality of a region of a sphere is determined using:

x^2 + y^2 + z^2 \le r^2

Substitute 5 for r

x^2 + y^2 + z^2 \le 5^2

x^2 + y^2 + z^2 \le 25

Solving further: <em>The question says only the upper hemisphere is considered.</em>

This implies that:

z \ge 0

<em>So, the equation is:</em>

x^2 + y^2 + z^2 \le 25

z \ge 0

A redundant constraint is one which Group of answer choices is added after the problem is already formulated. can only increase
Xelga [282]

Answer:

Plays no role in determining the feasible region of the problem.

Step-by-step explanation:

A Constraints

These are refered to as the restrictions that hinders or reduces the extent to which the/an objective can be worked on/pursued.

A redundant constraint

These are constraints that can be ignored from a system of linear constraints. It is often refered to as an Implied constraints. That is, they are implied by the constraints that surrounds (totality of) the problem.

This is a type of constraint that is not influenced or affected by the feasible region.

Its qualities includes

1. It does not hinders the optimal solution.

2. It also do not hinders the feasible region.

3. It is easily known with the use of graphical solution method
