Step-by-step explanation:
<em>The question is incomplete as the polygon A (and other possible polygons to select from) are not given. So, I will answer on a general term.</em>
<em></em>
Assume that Polygon A is a rectangle of dimension 2ft by 5ft.
Possible scaled copies can be gotten by multiplying the dimension of A by the same scale factor.
Take for instance, the scale factor k is:
A scaled copy of polygon A (say polygon B) is: 6ft by 15ft
This is gotten by:
The area of A is:
The area of B is:
<em>See attachment for polygons</em>
<u></u>
<u>Comparison</u>
The area of B is greater than the area of B.
<em>This method can be applied to scale factors</em>
The level of the curves are all the eclipses with the major axis.
100 50 1
a2 = ------ - 1 , b2 = ------- - -----
C C 2
Given that:
100
T(x, y) = ------------
1 + x2 + y2
This implies that the level curves of a function(f) of two variables relate to the curves with equation f(x, y) = c
where c is the constant.
100
C = ------------ ----- (1)
1 + x2 + y2
By cross multiply
C (1 + x2 + y2) = 100
1 + x2 + y2 = 100/C
100
x2 + y2= --------- - 1 -----(2)
C
From (2); let's assume that the values of c > 0 likewise c < 100, then the interval can be expressed as 0 < c <100.
Now,
(x)2 (y)2
------ + ---------------
100 50 1
------ - 1 ------- - -----
C C 2
This is the equation for the family of the eclipses centered at (0,0) is :
x2/a2 + y2/b2 = 1
100 50 1
a2 = ------ - 1 b2 = ------- - -----
C C 2
Therefore; the level of the curves are all the eclipses with the major axis:
100 50 1
a2 = ------ - 1 b2 = ------- - -----
C C 2
and a minor axis which satisfies the values for which 0< c < 100.
The sketch of the level curves can be see in the attached image below.
