    Moving to maths for you

    Posted from TSR Mobile

    9 (a) Try to put both sides of the equation in terms of a single log, as in, make the equation of the form

    \log_a (x+4) = \log_a (blah) by combining the two log terms together using a well-known log rule.

    Once you've done that, you can simply say that x+4 = blah since the logs are the same bases.

    (b) Do the same thing as above. Except note the use of a subtraction of logs instead of addition, combining the logs leads to...?

    (c) Once you've found both x and y, this shouldn't be hard.

    10. (a) The initial number of fish is just the amount of fish there was at the beginning, or at t=.... At the beginning, t is equal to what? Substitute that in to find how many fish there was.

    (b) You know that n=3600, t=3. Sub those into the equation given and re-arrange and manipulate to get c.

    (c) For the fish to double in size, how would you interpret this mathematically, using your previous answers.

    Ask if anything is still unclear.
