Given:
The power generated by an electrical circuit (in watts) as a function of its current x (in amperes) is modeled by
To find:
The current which will produce the maximum power.
Solution:
We have,
Differentiate with respect to x.
...(i)
To find the extreme point equate P'(x)=0.
Divide both sides by -30.
Differentiate (i) with respect to x.
(Maximum)
It means, the given function is maximum at x=4.
Therefore, the current of 4 amperes will produce the maximum power.
Answer:
$38.40
Step-by-step explanation:
to get your total you multiply
48 x 20% =9.60
then you subtract 48.00 - 9.60 = $38.40
Answer:
A, C
Step-by-step explanation:
16 blocks.
You drive 2 blocks west and 5 blocks North to get to school.
You then have to drive 8 blocks east and 1 block south to get to your friends house.
They’re all different directions so just add them all up. You get 16
Answer:
The last option y<4. Y is less than 4 since the shaded region is below 4 on the y Axis.
