Answer:
5 amperes will produce the maximum power
Step-by-step explanation:
The power generated by an electrical circuit (in watts) as a function of its current c (in amperes) is modeled by: P(c)= -12c^2 + 120c.
To find out the maximum power we need to find the vertex
formula to find x -coordinate of vertex is 
P(c)= -12c^2 + 120c is given in the form of y=ax^2+bx+c
a= -12, b = 120
c= 5 amperes will produce the maximum power
Answer:
I cant see your post...
Step-by-step explanation:
The first answer is 0.38(x^2)-2.45x+5.1. first, on a graphing calculator, you enter the data in the chart into stat edit. then you turn on stat plot 1 and press graph. press stat calc quadreg to find the equation. then, substitute 9 in for x to find that there will be 13.83 thousand bacteria after 9 hours
5814/27 = 215.33
215 x 27 = 5805
5814-5805 = 9
Answer is B 215 sections with 9 feet left over
<span>7.71(–0.02)
</span><span>0.23(–1.1)
</span><span>–5.09(8.1)
The reason is because a negative * positive will always give a negative answer. Negative * negative and positive * positive will always have a positive answer.</span>
