Answer:
The bottom one. The side with the 12 x 5 side.
Step-by-step explanation:
12 x 5 =60. That is bigger than the other sides
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:
i dunno
Step-by-step explanation:
You subtract the % that the sale is and take it away from 100%. You get 75% then take the original price and divide it by .75
