Answer 1

Answer:

Dehydration can have causes that aren't due to underlying disease. Examples include heat, excessive activity, insufficient fluid consumption, excessive sweating or medication side effects.

Answer 2

Answer:

Using AM≥GM on p and q

2p2+q2≥pq

⇒pq≤21(∵p2+q2=1)

Now, (p+q)2=p2+q2+2pq

⇒(p+q)2=1+2pq

⇒(p+q)2≤1+1

⇒p+q≤2
