Answer:
-3, -1, 1
Step-by-step explanation:
-18 divided by 6 is -3
now guess and check the 3 consecutive odd numbers that work
angle BCA should be the same as angle CAD -> 20°
The first option is correct.
Moving 1.5 units to the left (or -1.5 units to the right).
Moving 1 unit down (or -1 unit up).
Therefore you get the result of (-1.5, 1) as is the location of the rink.
.........................It is 40.
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.
