I=w/12.6r^2 where I is the intensity of light, w is the wattage of the light bulb and r is the distance to the light bulb. Let w
Alenkinab [10]

Answer:

2.0491 watt per meter square

Step-by-step explanation:

We are given the following in the question:

The intensity of light is given by:

I = \dfrac{W}{12.6r^2}

where W is the wattage of the light bulb and r is the distance to the light bulb.

We have to evaluate the intensity of bulb with W = 100 watts and r = 2 meters.

Putting values, we get,

I = \dfrac{100}{12.2(2)^2} = 2.0491\text{ watt per meter square}

Thus, the intensity of light bulb is 2.0491 watt per meter square.

Valentin [98]

Answer:

\frac{31}{50}

Step-by-step explanation:

First, find how many have an Atlantic or Pacific coastline:

14 + 5

= 19

Then, subtract this from 50:

50 - 19

= 31

This means 31 out of the 50 states have neither coastlines:

This is \frac{31}{50} as a fraction

Which of the following equations represents a line that is parallel to the line 3x - 2y = 12
sveticcg [70]

Answer:

Step-by-step explanation:

12=3x-2y

2y+12=3x

2y=3x-12

y=(3x-12)/2

y=mx+b

To be parallel to the line above our line must have the same slope or m. The above line has a slope of 3/2 or 1.5 so the parallel line will be

y=1.5x+b, using point (7,10) we can solve for the y intercept or b

10=1.5(7)+b

10=10.5+b

b=-0.5 so our line is

y=1.5x-0.5
