How many silver coins ,2cm in diameter and of thickness 2mm,must be melted to form a showpiece in the form of frustum of a cone having height 9cm and radii of outer circular ends as5cm 3cm
Thewhat is the difference between the mean and median of the first four prime numbers that are more than 4? The mean=9 and the median =11.so the ans should be -2.but in the answer sheet the ans is 0..how?
Mean=9 Median=11 Is it right? Then the difference between them is -2. But here in the answer sheet the ans is 0!!im really confused
What is the difference between the mean and median of the first four prime numbers that are more than 4?
If a,b,c are integers and b²=4(ac+5d²), d N then roots of the eqn ax²+bx+c=0 are
Let a,b and c be real numbers such that 4a+2b+c =0 and ab>0. Then the eqn ax²+bx²+cx²=0 has-
Consider the eqn x²+2x-n =0 where nN and n[5,100]. Total no. Of different values of 'n' so that the given eqn has integral roots is-
If the roots of the eqn x²-2cx+ab=0 are real and unequal, then prove that the roots of x²-2(a+b)x+a²+b²+2c²=0 will be imaginary.
For what values of k the expression kx²+(k+1)x+2 will be a perfect square of a linear polynomial.
Show that if roots of eqn (a²-bc) x²+2(b²-ac)x +c²-ab=0 are equal then either b=0 or a³+b³+c³=3abc.
If a,b and c R, then prove that the roots of the eqn 1/(x-a) + 1/(x-b) + 1/(x-c) =0 are always real and cannot have roots if a=b=c.
If the roots of the eqn 1/(x+p) + 1/(x+p) = 1/r are equal in magnitude but opposite in sign, show that p+r=2r and that the product of the roots is equal to (-1/2) (p²+q²)
If 2+i√3 is a root of the eqn x²+px+q=0, where p,q belongs to R, then find the ordered pair (p,q)

What is the temperature when water freezes? I have one more question What is the temperature when it steams?
the role self-respect (in this context it means respect for one's own physical safety) play in an individual's response to injustice.
PLEASE ANSWER MY QUESTION! THANK YOU! WHAT IS A PLOT? A plot (in mathematics and engineering) is a graph. It geography, it is a piece of land. In a cemetery, it is a grave site. It can also be a covert plan of action or conspiracy. In English a "plot" can be the form...
