Answer:
D: (0,3)
Step-by-step explanation:
The Lagrangian is

with critical points where the partial derivatives vanish.



Substitute
into the last equation and solve for
:

Then we get two critical points,

We get an absolute maximum of
at the second point, and an absolute minimum of
at the first point.
20% of x=6
20/100 of x=6
20x= 600
x=30
38% of 30=11.4
B is true

B. The product of two irrational numbers if rational
Example: The square root of 2 times the square root of 3, is the square root of 6, which is still irrational.
