Show that the sum of the reciprocals of three different positive integers is greater than 6 times the reciprocal of their produc
Montano1993 [528]
If a,b,c are the 3 positive integers
1/a +1/b +1/c > 6/abc
(bc+ac+ab)/abc >6/abc so
(bc+ac+ab)>6
The lowest positive integers that are different are 1,2,3 so the lowest value that (bc+ac+ab) could have is 1•2+2•3+1•3=2+6+3= 11 therefore
1/a +1/b +1/c > 6/abc is true

The height of a cylinder is equal to the diameter of the base What expression represents the volume of the cylinder, in cubic un
Sveta_85 [38]

Answer: 3 units

Step-by-step explanation:

the volume of a cone C = πr²h/3

C = 18π, h =2x, r = diameter/2 = 2x/2 =x

18π = π* x²* 2x/3

divide through by π

18 = x² * 2x/3

multiply through by 3

54 = 2x³

divide through by 2

27 = x³

x =∛27 = 3

x = 3 units = radius

Solve for x. 0=65892.56*x^(-1.67)
scoundrel [369]
0=65892.56\cdot x^{-1.67}

It would seem the only solution is 0, but x^{-1.67}=\frac{1}{x^{1.67}} and the denominator of the fraction can't be equal zero, therefore there's no solution.
