Answer:
The correct option is;
1955 to 1970
Explanation:
In the two decades after 1950 the marine and inland fisheries growth rate was 6 % per year reaching 56 million tonnes in 1969 from 18 million tonnes in 1950. There was a reduction in growth rate to 2 million tonnes to 2 % per annum reducing further to about 0 % in the 1990s.
The above trend is consistent with most world's fishing areas, as they reached their captured fisheries production maximum potential.
On the other hand, aquaculture production growth rate has increased from 5% per annum between 1950 to 1969 to 10% per annum in 1990 forward.
Answer: p^2 + 4q^2 + r^2 + 4pq + 4qr + 2pr
Explanation:
We need to expand (p+2q+r)^2
We know that (x+y+z) ^2 = x^2 + y^2 + z^2 + 2xy + 2yz + 2xz
Here x = p,y = 2q and z = r
Therefore (p+2q+r)^2 = (p)^2 + (2q)^2 + (r)^2 + 2(p)(2q) + 2(2q)(r) + 2(p)(r)
= p^2 + 4q^2 + r^2 + 4pq + 4qr + 2pr
