Answer:
240
Step-by-step explanation:
The circuit's power is modeled by a quadratic function, whose graph is a parabola.
The maximum power is reached at the vertex.
So in order to find the maximum power, we need to find the vertex's y-coordinate.
We will start by finding the vertex's x-coordinate, and then plug that into P(c).
The vertex's x-coordinate is the average of the two zeros, so let's find those first.
-15c(c-8)=0, so either -15c or c-8 equals 0, so c=0 or c=8.
Now let's take the zeros' average:
(0+8)/2=4.
The vertex's x-coordinate of this parabola is 4. Now let's find P(4).
P(4)=-15(4)(4-8)
240.
The maximum power of this circuit is 240 watts.
