y=4x+35
Step-by-step explanation:
Answer:
Step-by-step explanation:
This is a homogeneous linear equation. So, assume a solution will be proportional to:
Now, substitute into the differential equation:
Using the characteristic equation:
Factor out
Where:
Therefore the zeros must come from the polynomial:
Solving for :
These roots give the next solutions:
Where and are arbitrary constants. Now, the general solution is the sum of the previous solutions:
Using Euler's identity:
Redefine:
Since these are arbitrary constants
Now, let's find its derivative in order to find and
Evaluating :
Evaluating :
Finally, the solution is given by:
$1.32 per bottle because you would divide $5.28 into 4 and get $1.32
