Step-by-step explanation:

A 30 60 90 triangle tells us all the sides as long as we know one of the sides. (you can google it and it will show you). Looking at the picture added below, we can solve for j. The x in the picture is j and the 2x in the picture is 4. Thus we know that 2x=4 which means x=2

c. 1,233 miles

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)
