Asked by Jonathan

correction of previous question which I posted:
The power generated by an electrical circuit (in watts) as a functio of its current I (amperes) is modeled by: -4 I^2 + 152 I
check my work please,,,,thank you

-4 I^2 + 152 I
P= -8 I + 152 I
-8I + 152=0
-8I =-152
I=19
P(19)=4(19)^2 + 152(19) =`1444
P(19) = 1444 + 2888

P(19) = 4332 WATTS
Am i correct?
Thank you ...

I still don't understand the reasoning behind the first two lines, if they are related.

If power is the first line, then what is the P in the 2nd line?
Answered by Jonathan
Is 4332 WATTS correct though?
