08H Region

38. What is the distance between the points of intersectoin of the parabola y+6x^2+2 and circle x^2+(y-2)^2=29?

49. is a geo problem. if u guys have the test, i cant exactly figure out the picture. it says there are "cones" but i only see one?

59. is also a geo problem.

thanx!

38. Try using the sum/product of roots formulas to get everything you need for distance.

49. The other cone is pointing upward, sharing the base of the other cone, vertex at the antipodal point from the other vertex. Can you get it?

59. Solve [unparseable or potentially dangerous latex formula] and subtract the [unparseable or potentially dangerous latex formula]-values.

Ohhhh I didn't know they shared a base...no wonder lol.

59.Its becuz dervivative is slop right? So turning points is when y' is 0?

[AuSmith]

59. Mostly true. [unparseable or potentially dangerous latex formula] is a necessary condition for a turning point. So, if you find all the solutions to [unparseable or potentially dangerous latex formula], then you only need to decide the correct values, possibly by the second derivative which tells the curvature ([unparseable or potentially dangerous latex formula] is concave up is minimum, [unparseable or potentially dangerous latex formula] is concave down is maximum)... an example of when [unparseable or potentially dangerous latex formula], but is not a turning point is [unparseable or potentially dangerous latex formula] at [unparseable or potentially dangerous latex formula].

Be sure to subtract [unparseable or potentially dangerous latex formula]-values, not [unparseable or potentially dangerous latex formula].

hey ausmith, i found the study list. thanx! but, do they just take problems from different years and post it or something? or is it a preview of what is going to be on the 09 tests? because someone said the 65-70 problems are identical...but they have #77's?

[stupidityismygam]

the study list is a compilation of previous year's problems that the dude man likes and feels like we should know or something. So, the numbers are referencing where the problem originally came from. The study list problems will be the only problems that appear on 66-70, so if you become beastly and know how to do every problem in like -4 seconds, it is a free 25 points. yay?!

[B3ndythumbs]

err all of them? or just the ones that are numbers 67 or 77. btw, why do they go up to 80?

and btw, my coach kinda got mad at me for going into a pissing war with you. lols.

[B3ndythumbs]

so all of the geo and stated problems on the study guide pertains only to the last page? okay thanx!

umm i dunno? dont be surprised if he "talks" to you at elkins next week, if you're going.

[stupidityismygam]

I'm not...so I guess I dodged a bullet there!
