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?
• Registered User Posts: 73 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?
• - 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.
• Registered User Posts: 73 Junior Member
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.
• Registered User Posts: 986 Member
last one was 4, right??
• - Posts: 543 Member
What was the question??
• Registered User Posts: 73 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.
• - Posts: 543 Member
Toma, the answer for that was quadrants 1 and 4. But, ***WHAT WAS THE QUESTION WITH THE ANSWER OF 4???***
• Registered User Posts: 986 Member
@wcclirl The last one with the 2 sets of systems of equations..
• Registered User Posts: 30 Junior Member
Wcclirl, I remember the answer choices to be T only and so on... But not quadrants.
