Find and identify the traces of the quadric surface x2 + y2 − z2 = 36 given the plane. x = k Find the trace. Incorrect: Your ans
AlekseyPX

Answer:

Hyperbola.

Step-by-step explanation:

We start from the function:

x^{2} +y^{2} -z^{2} =36

We may get the traces if we cut the surface in planes x=k. This is equivalent to replace x for k:

k^{2}+y^{2} -z^{2}=36\\y^{2} -z^{2}=36-k^{2}

The last equation is the equation of an hyperbola, which varies its characteristics depending on K (the plane cut).

E = {10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23}
Nata [24]

Answer:

A=11,13,17,19 B=12,18 None=10,14,16,19 Both=15

Step-by-step explanation:

11,13,15,17,19 are all odd so they go in A

12,15,18 Are all multiples of 3 so they go in B

10,14,16,19 Are not classified so they go outside of the diagram but inside E

15 is odd and a multiple of 3 so put it in the center and not with A and B
