“Extraneous solutions are not solutions at all. They arise from outside the problem, from the method of solution. They are extraneous because they are not solutions of the original problem. ... To tell if a "solution" is extraneous you need to go back to the original problem and check to see if it is actually a solution.”

Basically, they are an answer you get when you solve a problem, but they don’t actually make the equation true so you disregard it.

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.

the height in feet of an object projected upward is given by the polynomial -16t^2+60t+90 where t represents time, in seconds. F

Karolina [17]

<u>Given</u>:

The height of an object project upward is given by the polynomial

$h=-16t^2+60t+90$

where t represents the time, in seconds.

We need to determine the height after t = 2.5 seconds.

<u>Height of an object:</u>

The height of an object after 2.5 seconds can be determined by substituting t=2.5 in the polynomial, we get;

$h=-16(2.5)^2+60(2.5)+90$

Simplifying, we get;

$h=-16(6.25)+60(2.5)+90$

$h=-100+150+90$

$h=140$

Thus, the height of an object is 140 feet.
