C is the midpoint of AB
Whereas D is the midpoint of AC
So AD + DC =CB is true
AD + DC = AC is true
and AD+DC+CB=AB is true
Therefore all statements apart from A are true.
I hope you understand.
Good luck
Answer:
I think it is D. Becuase you have to simplify the numarater then the demonater.
Given:
u varies directly with the square of p and inversely with d.
To find:
The equation for the given situation.
Solution:
If y is directly proportional to x, then
![y\propto x](https://tex.z-dn.net/?f=y%5Cpropto%20x)
If y is inversely proportional to x, then
![y\propto \dfrac{1}{x}](https://tex.z-dn.net/?f=y%5Cpropto%20%5Cdfrac%7B1%7D%7Bx%7D)
It is given that u varies directly with the square of p and inversely with d. So,
![u\propto \dfrac{p^2}{d}](https://tex.z-dn.net/?f=u%5Cpropto%20%5Cdfrac%7Bp%5E2%7D%7Bd%7D)
It can be written as:
![u=k\dfrac{p^2}{d}](https://tex.z-dn.net/?f=u%3Dk%5Cdfrac%7Bp%5E2%7D%7Bd%7D)
Where, k is the constant of proportionality.
Therefore, the required equation is
.
