How to find root hair

Mathematics
1 answer:
dimulka [17.4K]3 years ago

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.

How much much interest is on earned on an account if... Principal= $1,250 Rate= 5.7% Time= 4 year
Free_Kalibri [48]

Alright, lets gets started.

I suppose , we are asked to find simple interest for above question.

Principal P = $1,250

Rate r = 5.7 %

Time t = 4 years

The formula for simple interest = \frac{P*r*t}{100}

Hence simple interest = \frac{1250*5.7*4}{100}

Simple interest = \frac{28500}{100}

Simple interest = 285 $

Hence interest earned is $ 285. : Answer

Hope it will help :)
