Given a circuit with a voltage source of 24 Volts and a resistor rated at 1.5k ohms. What is the necessary wattage required for the resistor?
Equations Needed Ohms Law: V=IR P=VI First find current I=V/R I=24/1500 I=0.016 Amps P=VI P=24(0.016) P=0.384Watts This means a 1/2 Watt resistor will be required
f(x)=6x^3 -9x+4 find f(x)'
f(x) =6x^3 -9x +4 f(x)'= (3)(6)(x^3-1) - (1)(9)(x^1-1) + (0)(4) f(x)'=16x^2 -9
x^2 +4x +x=0 Solve for x
x^2 +4x+4=0 (x+2)(x+2)=0 (x+2)^2=0 x+2=0 X=-2
needs and Sullivan will reply soon.
