Answer:
(x -2)^2 +(y +4)^2 = 16
Step-by-step explanation:
The equation of a circle with center (h, k) and radius r is ...
(x -h)^2 +(y -k)^2 = r^2
You have (h, k) = (2, -4) and r = 4, so your equation is ...
(x -2)^2 +(y -(-4))^2 = 4^2
(x -2)^2 +(y +4)^2 = 16
Inequalities are used to compare unequal expressions.
The actual comparison is:
or 
The temperatures are given as:

From the above list, we have:


By comparison,
or 
Using absolute values, the inequalities are:
or 
Hence, the actual comparison is:

Answer:
Hence, the equation of a sphere with one of its diameters with endpoints (-9, -12, -6) and (11, 8, 14) is
.
Step-by-step explanation:
There are two kew parameters for a sphere: Center (
,
,
) and Radius (
). The radius is the midpoint of the line segment between endpoints. That is:


The radius can be found by halving the length of diameter, which can be determined by knowning location of endpoints and using Pythagorean Theorem:


The general formula of a sphere centered at (h, k, s) and with a radius r is:

Hence, the equation of a sphere with one of its diameters with endpoints (-9, -12, -6) and (11, 8, 14) is
