Answer:
$302,500
Step-by-step explanation:
If cost (C) = $7, then Sales (S) = 37,500 units
If cost (C) = $15, then Sales (S) = 17,500 units
The slope of the linear relationship between units sold and cost is:
The linear equation that describes this relationship is:
The revenue function is given by:
The cost at which the derivative of the revenue equals zero is the cost that yields the maximum revenue.
The optimal cost is $11, therefore, the maximum revenue is:
Answer:
Therefore and
are fundamental solution of the given differential equation.
Therefore and
are linearly independent, since
The general solution of the differential equation is
Step-by-step explanation:
Given differential equation is
y''-y'-20y =0
Here P(x)= -1, Q(x)= -20 and R(x)=0
Let trial solution be
Then, and
Therefore the complementary function is =
Therefore and
are fundamental solution of the given differential equation.
If and
are the fundamental solution of differential equation, then
Then and
are linearly independent.
Therefore and
are linearly independent, since
Let the the particular solution of the differential equation is
and
Here ,
,
,and
=0
and
=0
The the P.I = 0
