The power generated by an electrical circuit(in watts )as a function of its current c in s'mores is modeled by P(c)=-12c2+120c what current will produce the maximum power

5

Step-by-step explanation:

The maximum or minimum of a quadratic function occurs at x= −b/2a. If a is negative, the maximum value of the function is f(−b/2a). If a is positive, the minimum value of the function is f(−b/2a)

fmax

c=ac²+bc+c occurs at c=−b/2a

Find the value of c

equal to −b/2a

c=−b/2a

Substitute in the values of a

and b

c=−120/2(−12)

Remove parentheses.

c=−120/2(−12)

c=−60/−12

c= 5

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
