Ф = 3π/4. Transform it into Rectangular (or Cartesian) form .

The coordinates of Ф are x ,y  in rectangular form ==> so:

tan(Ф) = y/x and y=x . tan(Ф) ==> y= x. tan(3π/4). we know that tan(3π/4)= - 1

Hence y = - x

Answer:

Here,

Theta is Replaced by Angle A.

A=\frac{3\pi }{4}

Suppose any point on the two dimensional coordinate plane is (r,A).

Where A is angle made by line with positive direction of x axis and r is distance from Origin to that point.

Projection of point on X and Y axis  and then converting to Rectangular form

x=r Cos A, y=r Sin A\\\\ \frac{y}{x}=\frac{Sin A}{CosA}\\\\ y= x tan A\\\\ y=x* tan{\frac{3\pi}{4}

y=x \times (-1)\\\\ y=-x

→y= - x

is representation in Rectangular form of theta=\frac{3\pi }{4}

Afina-wow [57]

Answer:

B

Step-by-step explanation:

The first quartile of his data is 60.

The median of his data is 82.

The first quartile Q1 is the median of the lower half of the data set. This means that about 25% of the numbers in the data set lie below Q1 and about 75% lie above Q1.

The median Q2 is the median of  the data set. This means that about 50% of the numbers in the data set lie below Q2 and about 50% lie above Q2.

Between Q1 and Q2 lie exactly 25% of the numbers in the data set.

25% of 200 is exactly 50, so option B is true.

How to find root hair
dimulka [17.4K]
I'll proceed by evaluating total length and surface area by scanned images. For measurements, I suggest to use winrhizo or any similar software. In this case the most important thing to think about is to use the appropiate acquisition parameters, I mean, to set a good resolution during scanning. Pixels of the aquired image should be smaller than root hairs diameter. Therefore, let me try to suggest you a good acquisition resolution. Making a quick research, it seems that hair root diameters range between 0,012 and 0,017 mm, so I suggest a resolution that will give a pixel dimension of 0,002 mm. Root hair diameters should be composed by 6-8 pixels, that is enough for winrhizo measurements. Resolution is measured in dpi, so in "dots/pixel per inch". A inch is 25,4 mm. We need pixels with a diameter of 0,002 mm, so in 25,4 mm we found 12700 pixels. That means 12700 dpi. It's a very high resolution, you need a good scanner and much space in your computer.

0.135 written as a fraction is _____.<br><br><br><br> 5/37<br><br> 27/100<br><br> 27/200
sergij07 [2.7K]
First it would be 135/1000. Then you'd have to simplify.

Simplified, it would be 27/200.
