First find the critical points of <em>f</em> :
so the point (1, 0) is the only critical point, at which we have
Next check for critical points along the boundary, which can be found by converting to polar coordinates:
Find the critical points of <em>g</em> :
where <em>n</em> is any integer. We get 4 critical points in the interval [0, 2π) at
So <em>f</em> has a minimum of -7 and a maximum of 299.
Answer:
The answer to your question is 20 feet
Step-by-step explanation:
Data
A = (-2, 1)
B = (4, 1)
C = (-2, -3)
D = (4, -3)
Process
1.- Calculate the distance from C and D
dCD =
dCD =
dCD = 6
2.- Calculate the distance from A to C
dAC =
dAC =
dAC = 4
3.- Calculate the perimeter
Perimeter = 2(dCD) + 2(dAC)
-Substitution
Perimeter = 2(6) + 2(4)
-Simplification
Perimeter = 12 + 8
-Result
Perimeter = 20 ft
