Tangent to circle was that you find the point's coordinates, and use trig.

    No there's 60 questions in 60 minutes. I finished all of them.

    I put 2-sqrt(2) also, but that's a complete guess.

    I can't remember if I put 4 or 16 for the last one, but I solved it by multiplying the first equation by 3 and then adding the two equations together. The first system of equations where x and y were NOT under radicals had nothing to do with the question I think.

    for the pentagon one with the diagonals I got 72 but I kinda guessed; does anyone know how to actually do it?

    That ***** was hard for me

    Hoping for a 36... What did you guys get for the angle of the line that was tangent to the circle on the graph?
  • christiano241525christiano241525 Posts: 73Registered User Junior Member
    The angle question was easy once you realized the triangle shortcut; the angle divides into two 30 60 90 triangles, leaving the angle to be 30 + 30 = 60. Anybody know how to work last two questions? Scaling predictions

    what were the last 2 q's christiano?
  • wcclirl444wcclirl444 Posts: 543- Member
    ya, I realized that after about a minute or two. how about we just start a list of all of the Qs and As like usual so everyone can check their answers without having to ask individually.

    last question: it gave you one system of equations and then ask you to solve another. I ran out of time and guessed C/H.

    second to last one, I forgot what the question asked. also guessed.

    last one was 4, right??
  • wcclirl444wcclirl444 Posts: 543- Member
    What was the question??
  • christiano241525christiano241525 Posts: 73Registered User Junior Member
    I think you're right; it was 4 (I only know because I talked to someone else and that is what they got). I'm assuming 4 wasn't answer choice C, so I think I got that wrong.

    Yes. We should definately compile a list of questions and answers to give us ccers some peace of mind.

    What was the answer to the question that showed a graph with several sections labeled with letters? Also, I remember that the question had to do with soil and a planting business.
  • wcclirl444wcclirl444 Posts: 543- Member
    Toma, the answer for that was quadrants 1 and 4. But, ***WHAT WAS THE QUESTION WITH THE ANSWER OF 4???***
  • karatekid666karatekid666 Posts: 986Registered User Member
    @wcclirl The last one with the 2 sets of systems of equations..
  • Toma019Toma019 Posts: 30Registered User Junior Member
    Wcclirl, I remember the answer choices to be T only and so on... But not quadrants.
