9.74 because if you do 604 divided by 62 you will get 9.74 and if you do 9.74 and multiply it by 62 you will get 604<span />
Answer:
its a
Step-by-step explanation:
The Lagrangian,

has critical points where its partial derivatives vanish:





tells us
, so that


Then with
, we get

and
tells us

Then there are two critical points,
. The critical point with the negative
-coordinates gives the maximum value,
.
