Question

If √p - √q = 20 then what is the maximum value of (p - 5q)/100​

Answer 1

Answer:

5

Step-by-step explanation:

$\sqrt{p } - \sqrt{q} = 20$

squaring both sides we got

p = 400 + q + 40(q)^1/2 put in second equation

400 + q + 40(q)^1/2 - 5q = let x = q^1/2 therefore previous

100 eq. is a quadratic in x

formula for maximum value of quadratic is -D ------ D is discremenent

4a and is coffecient of q

HERE THE QUADRATIC IS IN NUMERATOR PART AND DENOMINATOR IS JUST A CONSTANT NO.

after solving , 500 ÷ 100 = 5

hope it helps to clear ur concept ☺☺✌✌✌✌
