Answer:
Plants are restrictive to flow of eroding agents, bind soil in their roots.
Step-by-step explanation:
Soil Erosion is the wearing away of the topmost fertile layer of soil. Topsoil gets eroded mainly due to wind, water agents.
Plants help to prevent soil from erosion in following ways :
- Plants act as restriction to the speed of air & water, which are the main soil erosion agents. It also lets rain water get soaked into the ground water.
- Plants roots also bind the soil tightly, & make soil stronger to be eroded by erosive agents - water, air. Eg : Shrubs , trees, grass & ground are important soil erosion preventive plants, because of their extensive root systems.
Answer:
BD = 8.8
Step-by-step explanation:
You have a right triangle.
The hypotenuse is BD
The side opposite the 27o angle is 4
Sin(27) = opposite / hypotenuse.
Sin(27) = 0.45399
opposite = 4
hypotenuse = ?
0.45399 = 4/hypotenuse
BD = 4/0.45399
BD = 8.811
The answer is 8.8
Answer:
The recursive formula for the given sequence
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given sequence is 8 , 16, 32, 64 ,.....
First term is a = 8
common ratio
and so on..
Given sequence of the common ratio 'r' is equal
The term of the sequence
This is recursive formula for the given sequence
<u><em>Verification</em></u>:-
put n=1 ⇒ t₁ = 8
put n=2 ⇒ t₂ = 16
put n=3 ⇒ t₃ = 32
put n=4 ⇒ t₄= 64
and so on..
The sequence 8 ,16 , 32 , 64 ....
Answer:
2 2/3 yd
Step-by-step explanation:
Let's convert from feet to yards. See how the feet cancel, because feet is in the denominator and the numerator?
8 ft x 1 yd/3 ft = 8/3 yd
As a mixed number:
8/3 = <u>2 2/3 yd of fabric</u>
