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).

The first tern of an arithmetic sequence is -3 and the fifteenth term id 53. What is the common difference of the sequence?
arsen [322]
The common difference is 4. U know that the formula is the first term + d(n -1). N-1 is 14 so u know that 14 times a number needs to equal 56 because the first term is -3 and 56-3 is 53. 14 * 4 is 56. So the common difference is 4
