2. 13, 28, 43, and 58
3. 1, 3, 5, and 7
4. -2, -18, -50, and -98

answer is more than one

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)

step-by-step explanation:

(x) - (y) = (1 + 4i)
