Let x = {1, 2} and let y = {3, 4}. define f : p(x) × p(y ) ? p(x ? y ) by f(a, b) = a ? b.
(a) find (a, b) ? p(x) × p(y ) such that f(a, b) = {2, 3}.
(b) find (a, b) ? p(x) × p(y ) such that f(a, b) = {2, 3, 4}.
(c) given c ? p(x ? y ), find (a, b) ? p(x) × p(y ) such that f(a, b) = c.

step-by-step explanation: the answer for wha if rt is 10 centimeters long, and wha is st? it’s 6

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)
