@please122 how would you get a circle ?

@please122 92 for pizza topping question because you just use the calculator and do (8 choose 3) + (8 choose 2) + (8 choose 1)

@CrimsonZa I guess I got that one wrong : /

I got circle and point and as for other that believe it’s just 2 I will argue why it is infinite. The slope can change in very small amounts from -.01 to -.02 and so on until a certain slope value which you can set so it never reaches creating infinitely many lines or possible lines that never intersect the function.

I agree with the 2 VA but also believe there could be another line such as y=-x that would not intersect.

@please122 I got 1005 and 48 for term 3

@introver yes I got only 3 for the symmetrical one, but 2 for the lines that do not intersect

@please122 the arithmetic sequence question I got 1001 because 5+ 4(249) = 1001

@goodstudent38 I agree I put 1001.

@goodstudent38 is correct it should be 1001 not 1005 my mistake

@goodstudent38 I think you’re right about that one actually

I got 92 as well. As for the infinite I still think it’s 2. Even a slight change in gradient wouldn’t cause it
To intersect …I think

@introver please explain why it was only 3 symmetrical

I got 1001 too

@introver how did you get a circle for the intersection question

What was the symmetrical question ?

it was (x+1)^3, sqrt(25-x^2), and 1/x

I put I and III

@Jetski123 after graphing one was symmetrical over y another was shifted left bc of the +1 so those were not symm over the origin but III was over the origin

@please122 I got 1001 for arithmetic sequence because n was 250
