Let

The curl is

where
denotes the partial derivative operator with respect to
. Recall that



and that for any two vectors
and
,
, and
.
The cross product reduces to

When you compute the partial derivatives, you'll find that all the components reduce to 0 and

which means
is indeed conservative and we can find
.
Integrate both sides of

with respect to
and

Differentiate both sides with respect to
and




Now

and differentiating with respect to
gives




for some constant
. So

Answer:
12.5%
Step-by-step explanation:
1 dozen=12
5 dozen= 60
Earnings= 9x60= rs 540
Profit= 540-480= rs 60
Percentage profit= 60/480×100%=12.5%

Step-by-step explanation:
3:5= 1.5:2.5
Each number is divided or multiplyed by the same number.
Ex. 3/2=1.5 and 5/2=2.5
Hope that helps idk if its right though lol
Solution here,
dimentions of is 20 in. by 10 in. by 12 in.
i.e. volume of tank=20×10×12=2400 cu. in.
Again,
the tank holds 10 gallons of water
i.e. 10 gallons of water occupies 2400 cu. in.
so, 1 gallon of water occupies 2400/10 cu.in.
=240 cu.in
