What is enriched uranium? a. U-238 b. U-235 c. U-235 + Radium d. U-235 + U-238

If U + V = 80 and U : V = 5 : 3, then what is the value of U-V ?

Let U be the universal set B, C are sub-sets of U. If A = B cup C , then U -(U - ((U-A')))) is equal to

Q. which of the following is the derivative of f(u) = (2u+1)/(u-2) ? A. f'(u)=2 B. f'(u)=5/(u-2)^2 C. f'(u)=(4u-5)/(u-2)^2 D. f'(u)=5/(u-2) E. f'(u)=(4u-5)/(u-2)

Find the point of discontinuity of y=f(u) where f(u)=(3)/(2u^(2)+5u-3) and u=(1)/(x+2)
