A stack of printer paper is 2 inches thick and contains 500 sheets. estimate the thickness of an individual sheet of the printer
Harrizon [31]

The thickness of an individual sheet of the printer paper is 101.6 micrometer.

<h3>What is unit conversion?</h3>

Unit conversion is a multi-step process that involves multiplying or dividing by a mathematical factor or, more specifically, a conversion factor.

  • The procedure may also necessitate selecting the appropriate number of critical digits and rounding.
  • Different conversion units are used to evaluate different parameters.

Now, according to the question.

The total number of sheets are 500.

The thickness of stack of sheets are 2 inch.

convert 2 inch in cm;

2 inch  = 2× 2.54 cm

2 inch = 5.08 cm.

Thickness of 1 sheet = Total thickness/Total sheets

Thickness of 1 sheet = 5.08/500

Thickness of 1 sheet = 0.01016 cm

Covert this thickness in micrometer.

1 micrometer = 1/1000 cm

1 cm = 10000 micrometer

Thus,

0.01016 cm = 0.01016×10000

0.01016 cm = 101.6 micrometer

Therefore, the thickness of an individual sheet of the printer paper is 101.6 micrometer.

Graph the function f(x) = x3 – 3x – 2. Based on the graph, which value for x is a double root of this function? a.–2 b.–1 c.1 d.
dalvyx [7]
To solve the problem shown above you must apply the following proccedure:

 1. You have the following function given in the problem:

 <span> f(x)=x3–3x–2

 2. When you give values to the x and plot each point obtained, you obtain the graph shown in the figure attached.

 3. Based on the graph and analizing the alternate form:

 f(x)=(x-2)(x+1)</span>²

 As you can see, there is two roots x=-1, then, you can conclude that the correct answer is the option b, which is:

 b) -1
