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.
PLEASE MARK BRAINLIEST AND VERTIFIED ANSWER!! I spent a lot of time on this... :P thank you!!
<span>First, let’s check for the given:
Shirts on the rack = 240</span>
Medium size shirts = 40% of 240
<span>With the following given, we can now solve for the total
number of shirts on the rack that are size medium.
So, in order to solve for the problem, we multiply 40% to 240:</span>
<span>The decimal equivalent of 40% is 0.4.
240 shirts * .4 = 96 shirts</span>
Therefore, out of 240 shirts on the rack, there are 96 shirts
on the rack that are size medium.
To add, the number or ratio that represents a fraction
of 100 is called a percentage.

Correct option is B.
Answer:
2.5mg
Step-by-step explanation:
Since the half-life for the radioactive material is 3 hours, Therefore it will undergone two times of half-life process.
The first 3 hours 10mg will be decreased into 5mg. The final 3 hrs, it will decreased from 5mg to 2.5mg
