Answer:
Triangle Proportionality Theorem is defined by a line parallel to one side of a triangle divides the other two sides proportionally.
Step-by-step explanation:
Triangular Proportionality Theorem states that:
- If a line parallel to one side of a triangle intersects the other two sides, then it divides those sides proportionally.
Let us consider the triangle ΔABC as shown in attached figure.
If
║
then
Therefore, Triangle Proportionality Theorem is defined by a line parallel to one side of a triangle divides the other two sides proportionally.

Answer:
a)
b) 54
Step-by-step explanation:
a)
If one quantity, A, is jointly proportional to other 2 quantities (B & C), we can write proportionality equation as:
Where
k is the proportionality constant
Now, for this problem, P is jointly proportional to A and CUBE OF V, so we can write:
b)
Now velocity, V, is triples, which means it becomes 3V
Also, cross sectional area, A, is doubled, which means it becomes 2A
Let's put these into formula and see the difference:
So, power is multiplied by a factor of 54. Power becomes 54 times if Area is doubled and velocity is tripled ( as seen ).
