Prove that if a graph g has 11 vertices, then either g or its complement g must be nonplanar. (hint: determine the total number n11 of edges in a complete graph on 11 vertices; if the result were false and g and its complement were each planar, how many of the n11 edges could be in each of these two graphs? )

the answer is c. hope this !

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
