Answer:
5
Step-by-step explanation:
5 amperes will produce the maximum power
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: Your paying 27 dollars. Your saving 33 dollars.
Step-by-step explanation: I used a calculator :)
i think it is A the first option
(-14) ÷ (-34)
14/34
= ⁷/17
7.2 gallons
2.25 x 3.2 = 7.2
