" Q."8" Foreach real number "x" such that "-1

Write the negation of the following statement: i. p: for every positive real number x, the number x-1 is also positive. ii. q : All cats scratch. r: For every real number x, either x>1 or x iv. s : There exists a number x such that 0ltxlt1 .

If p and q are positive real numbers such that p^(2)+q^(2)=1 then find the maximum value of (p+q)

if p and q are positive real numbers such that p^(2)+q^(2)=1 then find the maximum value of (p+q)

If p and q are positive real numbers such that p^2+q^2=1 , then the maximum value of p+q is

If p and q are positive real number such that p^(2) + q^(2) = 1 , then the maximum value of (p + q) is :

If p and q are positive real numbers such that p^2+q^2=1 , then the maximum value of p+q is

If p and q are positive real numbers such that p^2+ q^2=1 , then the maximum value of (p +q) is :

If p and q are positive real numbers such that p^(2)+q^(2)=1 then the maximum value of (p+q) is

If p,q,r and s are real numbers such that pr=2(q+s), then show that at least one of the equations x^(2)+px+q=0 and x^(2)+rx+s=0 has real roots.
