Answer:
How do I keep falling for this trick!???

is conservative if we can find a scalar function
such that
. This would require



Integrating both sides of the first equation wrt
gives

Differentiating both sides of this wrt
gives

but we assumed
was a function of
and
, independent of
. So there is no such
and
is not conservative.
To find the work, first parameterize the path (call it
) by

for
. Then

and the work is given by the line integral,


C = 5/9(F - 32)
F = 62
C = 5/9(62 - 32)
C = 5/9(30)
C = 150/9
C = 16.7 <===
Answer:
80
Step-by-step explanation
250% is 2.5 so 200 divided by 2.5 is 80
