Barry's deck of cards has 40 blue and 70 red. max has 40 blue cards, but the ratio of blue cards to red is 8: 9. how many total cards does max deck have?

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)
