  2. Should we do the survey for Grade 6-8 because it doesn't give you the option of ninth grade algebra. Which one should we do?

  9. Well, #15 is

    Evaluate:
    g(t)= 2*(.4)^t where t=-2

    So, YOU should know that
    .4=2/5

    (2/5)^(-2)=(5/2)^2, right??

    I think you can solve it from here, with or without help from Elmo (the mystical, magical, and righteous math god), yes??

  10. #17 was a little unfair... they should have specified that they wanted the answer in SciNot rounded to two decimal points. I would not be that cruel (well, at least on purpose)

    Calculator giving you problems with -0.5*4^18

    well 4^9=262155 which=2.62144 x 10^5 right?

    so 4^18 = (4^9)^2 right?

    so (4^9)^2 = 2.62144 x 10^5 * 2.62144 x 10^5 right?

    so, -0.5*4^18 must =

    -0.5 * 2.62144^2 * 10^10 right?

    so, scientific notation gives you

    -3.4359 x 10^10

    rounded
    -3.44 x 10^10
