Which pair of ratios from a proportion a.4/5 and 16/24 b.9/15 and 3/4 c.5/8 and 30/48 d.9/10 and 40/45

C because 6 x 5 is 30 and 6 x 8 is 48

So

6(5/8) = 30/48

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)
