Answer:
False
Step-by-step explanation:
The given statement is:
The coefficient of x^ky^n-k in the expression of (x+y)^n equals (n-k/k)
This is a false statement
Reason:
When we do expansion of (x+y)^n by binomial theorem we get the following solution:
(x+y)^n = nCk x^k y^n-k
This shows that the coefficient of x^ky^n-k is nCk which is equivalent to n!/(n-k)! k!
Therefore it is a false statement....

Answer:
The dimension of box=
Step-by-step explanation:
We are given that
Volume of box=4 cubic feet
Let x be the side of square base and h be the height of box
Volume of box=


Now, surface area of box,A=








Substitute x=2

Hence, the area of box is minimum at x=2
Therefore, side of square base,x=2 ft
Height of box,h=
Hence, the dimension of box=
