This problem can be solved by manipulating the formula for power, which is: P = VI. Where:

P = Power in watts
V= Voltage in volts
I = Current in amperes

Since we are already given the power and voltage, simple substitution can be done.

P = VI
3.5 watts = 120 volts * I
I = 3.5 / 120
I = 0.0292 Amperes or 29.2 milliAmperes

Therefore, the current through the bulb is 29.2mA

Determine the line described by the given point and slope (0,0) and 2/3
AlekseyPX

Answer:

The  line is  y=\frac{2}{3} x.

Step-by-step explanation:

Given:

Point and slope (0,0) and 2/3.

Now, to determine the line.

Here the point is:

(x_{1},y_{1}) =(0,0)

And the slope is:

m=\frac{2}{3}

Now, putting the formula and substituting the value from above to determine the line:

y-y_{1} = m(x-x_{1})

y-0=\frac{2}{3}(x-0)

y=\frac{2}{3} x

Therefore, the  line is y=\frac{2}{3} x.

The area of a sector of a circle with a radius measuring 15 cm is 75(pi) cm2. What is the measure of the central angle that form
anyanavicka [17]

The sector of the circle is bounded by 2 radii, and the measure of the central angle that forms the sector is 120 degrees

<h3>How to determine the central angle?</h3>

The given parameters are:

  • Area = 75π cm^2
  • Radius, r = 15 cm

The area is calculated using

Area = α/360 * πr^2

So, we have:

α/360 * π * 15^2 = 75π

Evaluate the exponent

α/360 * π * 225 = 75π

Divide both sides by 75π

α/360 * 3 = 1

Multiply

α/120  = 1

Multiply both sides by 120

α = 120

Hence, the measure of the central angle that forms the sector is 120 degrees
