supposed to be? Can't answer a/b without that information.
I'll come back to part (c) in a moment. If we can show
is conservative, this part will be a breeze.
For part (d), to show whether
is conservative, we have to show that there is a scalar function
such that
. It appears that you've written
I'm not sure what to make of the
that follows.
means that
Integrating the first PDE with respect to
gives
Differentiating with respect to
gives
But we assumed that
is a function of
alone, which means there is no solution for
, and therefore no solution for
. Hence
is not conservative.
Back to part (c).
is not conservative, so we have to compute the line integral the "long" way. Replacing
and
, we have
Answer:
88 deg
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary. That means that the sum of the measures of angles O and Q is 180 deg.
2x + 2x + 4 = 180
4x + 4 = 180
4x = 176
x = 44
m<O = 2x = 2(44) = 88
Answer: 88 deg
Divide by the greatest common factor.. The answer is 2/3
Answer:
False
Step-by-step explanation:
FalseFalseFalse
f(x)=(x+4) ^2 −25
to solve set equal to zero
0 =(x+4) ^2 −25
add 25 to each side
25 = (x+4) ^2
take the square root of each side
square root (25) =(x+4)
+- 5 = (x+4)
5 = x+4 -5 = x+4
subtract 4 from each side
1 =x -9 =x
