    I have 2 questions about the free response…
    for the one where you had to simplify an expression by factoring, how many points would you get if you only factored a number out and forgot to use the “diff of two perfect squares” thing to break it down again?

    and for the last question, I solved it and got my x values but forgot to write the y values….I mean 5.5 and .5 are on my paper but I only wrote it on my check area and didn’t say y=5.5, y=.5….i just wrote 5.5=5.5 and .5=.5 to make sure that the equations were equal….i think the question was 6 points, how many did this cost me?

    thanks!

      You got 5 out of 6 points for two x values, two y values or one x and one y value.

    19. I had no idea that arccos was defined that way. I love New York and its silly ways. You guys ….

      They sort of conceded, but then insisted (correctly) that there is a best answer, even if there is not a right answer. It is essentially the same mistake as on #32 – whoever was working on proofing this thing never really understood inverses.

    Only got three wrong. Stupid mistakes!

    Some minor thoughts:
    8. The graph is missing a visual illustration of the asymptote.
    9. What is considered the “first term” of the sequence? It would be better to ask “In a geometric sequence, a_1 = blah, a_2 = blah, a_3 = blah. Compute a_15.”
    10. I assume calculators are allowed? I was able to guess at the answer, knowing that a 13-14-15 triangle breaks down into 5-12-13 and 9-12-15 right triangles, but I assume that’s not common knowledge…
    14. Kate already commented on this one…
    16. OTL
    19. O_o
    26. The problem assumes an ordering of terms. Should the answer be the same if the question were written as (-4b + a)^9? If the idea is to calculate the coefficient of the a^6 b^3 term, then that’s what the question should ask!
    27. Rather than “appropriate”, the question is asking which regression would fit the data the best. One might also make the argument that an exponential and logarithmic regression are equivalent depending on which variable is independent, and which variable is dependent.

    Do you think you could post the answers or just questions to/of the Geometry Regents June 2011?

    What did they decide for 16? Rationalize the denominator as the “only” correct choice if they’d asked for simplified or did they allow (1) as a correct answer to the question? It is equivalent, after all.
