If no digit appears more than once, how many 3-digit numbers can be formed from the digits 2, 3, 4, 6, and 7? ? how did you receive that answer? ?

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)

step-by-step explanation:

yes, i think so although i am not sure. this is a very strange question.
