Hope this helped :)
Using the method of Lagrange multipliers, we have the Lagrangian

with partial derivatives (set equal to 0)





From

and

, we find that

. Then substituting into

, we find

and substituting these into

, we get

So we have two possible critical points,

, which give extreme values of

and

, respectively.
Answer:D
Step-by-step explanation:
The equation is y=mx+b. Here the slope is 1/5 and b is 5
Answer:
a=41.8 BC=2.8
Step-by-step explanation:
sin30/6=sinx/8
8*sin30=6sinx
4=6sinx
sin^-1(4/6)
angle a
cosine rule
bc^2=3^2 +5^2-2(3)(5)*cos30
BC^2=
BC=2.83
2.8
