what ia meant by green revolution​

Answers

Answer:

Green revolution, great increase in production of food grains (especially wheat and rice) that resulted in large part from the introduction into developing countries of new, high-yielding varieties, beginning in the mid-20th century. Its early dramatic successes were in Mexico and the Indian subcontinent. The new varieties require large amounts of chemical fertilizers and pesticides to produce their high yields, raising concerns about cost and potentially harmful environmental effects. Poor farmers, unable to afford the fertilizers and pesticides, have often reaped even lower yields with these grains than with the older strains, which were better adapted to local conditions and had some resistance to pests and diseases. See also Norman Borlaug

Answer: The introduction of High Yielding Varieties (HYV) of seeds and the increased use of chemical fertilisers and irrigation are known collectively as Green Revolution. It provided the increase in production needed to make India self-sufficient in foodgrains, thus improved the agricultural sector in India.

well, x = V1156 = 34

and hence the side lengths form a pythagorean triplet

Answer:

[tex] {x}^{2} = {16}^{2} + {30 }^{2} \\ {x}^{2} = 256 + 900 \\ {x}^{2} = 1156 \\ x = \sqrt{1156} \\ x = 34[/tex]

Is (x - 1) a factor of (x4 - 2x3 + x2 - x + 1)?
Factor?
Why? [Select]​

Answers

Answer:

here's the proof

Explanation:

x-1=0

x=1

so

f(x)=x⁴-2x³+x²-x+1

f(1)=1⁴-2.1³+1²-1+1

f(1)1-2+1-1+1

f(1)=2-2

f(1)=0

as we know When f(c)=0 then x−c is a factor of f(x)

hence x-1 is a factor of x⁴-2x³+x²-x+1
