    need help verifying answer ...




    so constant = h/w = 25/10

    constant = 2.5 , w = 10

    2.5 x 10 = 25

    would that be the answer ? or just 2.5?

    Dear bringash,

    I think this is one of your online exam questions. Therefore you are to do this yourself and I hope that the moderators of this forum will look into this matter.

    Dear bringash,

    In that case (thinking my assumption is incorrect!!) I shall give you my ideas about the question. The answer 2.5 is correct.

    Constant=\frac{H(w)}{w}=\frac{25.00}{10.0}=2.50 ; (using the rules of significant figures.)

    Since it is given that the answer could be rounded to first decimal place 2.5 is also correct.

    Hope this will help you.

    P.S: If you felt angry about my previous post I am really sorry about it. But MHF does not encourage any of it's members to give exam help.

    It can't be (d), try it with x = 2.

    Generally \sqrt{a}\sqrt{b} = \sqrt{ab}...

    Use \sqrt{a}\sqrt{b} = \sqrt{ab} to slit it up into \sqrt{2}\sqrt{x^2}\sqrt{4}\sqrt{x}, simplify, and then put the remaining radicals back together.

    according to that the answer would be (d) ?
