Which autocad command can we use to quickly calculate the area and perimeter of a closed region defined by a polyline?
polet [3.4K]

The answer is: The Area command.

The explanation is shown below:

1. The Area command is a very useful command in AutoCad, and you can use it to calculate  the area and the perimeter of a closed region draw with a polyline.

2. To use this command, you only need to type AREA and press the enter button. Then, you must select the points of the closed region and press enter again. Once you do this, the software will show you the perimeter and the area.

Michael plays 1/5 of a song in 1/15 pf a minute. How many minutes will it take to play whole song
mr Goodwill [35]
Well, a whole will be five fifths or 5/5.

now, he only plays 1/5 in 1/15, how many minutes will it take to play the whole 5/5 of the song?

\bf \begin{array}{ccll}
\stackrel{part}{song}&\stackrel{part}{minutes}\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
\frac{1}{5}&\frac{1}{15}\\\\
\frac{5}{5}&m
\end{array}\implies \cfrac{\frac{1}{5}}{\frac{5}{5}}=\cfrac{\frac{1}{15}}{m}\implies \cfrac{\frac{1}{5}}{\frac{5}{5}}=\cfrac{\frac{1}{15}}{\frac{m}{1}}\implies \cfrac{1}{5}\cdot \cfrac{5}{5}=\cfrac{1}{15}\cdot \cfrac{1}{m}

\bf \cfrac{1}{5}=\cfrac{1}{15m}\implies 15m=5\implies m=\cfrac{5}{15}\implies m=\stackrel{\textit{minutes}}{\cfrac{1}{3}}

What is the Pythagorean Theorem?

The PyTheorem states that -- actually, why not just simplify things and make it a formula?

a^{2} + b^{2} = c^{2}
where a and b are legs of a triangle and c is the hypotenuse of a triangle.

It is only true applying to right triangles.
Now what are the legs of a triangle? 
The sides that are NOT opposite the 90 degree angle! 

Now, all you have to do is find the LENGTHS of the three triangles!
Rise over run, remember?

Let's take the triangle in the top right of the coordinate plane for example.

A=(1,1)
B=(4,4)
unnamed point=(4,1)

Rise, or length of unnamed point to B?
(4,1) to (4,4)
(x,y), remember!
So? 4-1=3!

Run, or length of unnamed point to A?
(1,1) to (4,1)
Remember (x,y)?
So, 4-1=3!

The triangle has legs of 3 and 3.
Square em and add!
9+9=18
\sqrt{18}
\sqrt{3*6}
\sqrt{ 3^{2} *2}
3 \sqrt{2}

That's for length of AB!!
Now do the same for the remaining lengths!

Hope this helps!

Which table does not represent a linear function?
maks197457 [2]

Answer:

D . . . (it represents a quadratic function)

Step-by-step explanation:

The x-values are 1 unit apart for all values in all tables, making the problem much simpler. All you need to do is find the table where the y-value differences are not the same from one line to the next.

In table A, y-values decrease by 3.

In table B, y-values increase by 5.

In table C, y-values increase by 1.

In table D, y-values increase by 3, 2, 1—numbers that are not constant. (These differences decrease by 1, a number that *is* constant. Since the 2nd differences are constant, the table represents a 2nd degree function.)
