We're looking for a scalar function
such that its gradient is equal to the given vector-valued function
:
That is, we require
Integrating the first equation with respect to
gives
Differentiating with respect to
gives
but from this step we can see that it's not possible for
to be a function of
and
, independent of
. So there is no such function
.
Not quite 11/2 does equal 5.5 but you have to move the decimal point to the right twice
550% is the answer
Hello!
First we have to find out how much each copy cost
240 / 60 = 4
Since each magazine cost $4 the answer is y = 4x; (1,4), (2,8), (3,12)
Hope this helps!
Answer:
C and D

Once we do that, it becomes
2 1
1 2
2 1
or C
