Mains electricity is an ac supply. Explain the difference between direct and alternating potential difference.

1 answer:

5 0

Direct current (DC) is the flow of electric charge in only one direction. It is the steady state of a constant-voltage circuit. Most well-known applications, however, use a time-varying voltage source. Alternating current (AC) is the flow of electric charge that periodically reverses direction.

F(x) = 3x^2+5x-14 Find f(-9)

Llana [10]

Answer:

f(-9) = 184

Explanation:

f(x)=3x²+5x-14

f(-9)= 3(-9)² +5(-9)-14 Order of Operations : Exponents

= 3(81)+5(-9)-14

= 243+5(-9)-14

= 243-45-14

= 198-14

f(-9)= 184
