Answer with Step-by-step explanation:
The given differential equation is
Now the above differential equation can be re-written as
Checking for exactness we should have
As we see that the 2 values are equal thus we conclude that the given differential equation is exact
The solution of exact differential equation is given by
The value of can be obtained by differentiating u(x,y) partially with respect to 'y' and equating the result with P(x,y)
Answer:
total cost is $2444
Step-by-step explanation:
A company’s marginal cost function is where x is the number of units
Marginal cost function is the derivative of cost function
to find the total cost of producing units , take integral of marginal cost function
with intervals 144 to 625
now plug in the values
total cost is $2444
Simplify the ratio 8 to 2 to be 4 to 1
Now compare 4 to 1 and 10 to 1
4 is smaller than 10 so the ratio 8 to 2 is smaller.
