A current of c = 5A will produce the maximum power. Step-by-step ... P(c) = -12c² + 120c is a function of c. we know that for ... Pmax = -12(5)² + 120 x 5 = -300 + 600 = 300 watt.
Answer:
x = 7, x = -3
Step-by-step explanation:
We can find the zeros by factoring the equation using the zero product property.
x^2-4x-21 = 0
(x-7)(x+3) = 0
<u>x-7 = 0</u>
x = 7
<u>x+3 = 0</u>
x = -3
Zeros are x=7 and x= -3.
