Answer:
a. k = 27
b. k = 216
c. k = 0.216
Step-by-step explanation:
The value of the scale factor can be given by the following formula:
where,
Initial Volume = 8 cubic units
a.
Final Volume = 216 cubic units
Therefore,
<u>k = 27</u>
<u></u>
b.
Final Volume = 1 cubic units
Therefore,
<u>k = 216</u>
<u></u>
c.
Final Volume = 1000 cubic units
Therefore,
<u>k = 0.216</u>
Equation of an ellipse
→having center (0,0) , vertex ( and covertex
and focus
is given by:
As definition of an ellipse is that locus of all the points in a plane such that it's distance from two fixed points called focii remains constant.
Consider two points (a,0) and (-a,0) on Horizontal axis of an ellipse:
Distance from (a,0) to (c,0) is = a-c =
Distance from (-a,0) to (c,0) is = a + c =
a -c + a +c
= a + a
= 2 a →(Option A )
