3) Find x and XY if Y is between X and Z, XY = x - x inches, XZ = 12 inches, and YZ = 8x - 6 inches. X=
XY =

x = 2.25

XY = 0

Step-by-step explanation:

Since Y lies between X and Z

XY + YZ = XZ (whole part axiom)

x - x + 8x - 6 = 12

8x = 12 + 6

x = 18 / 8

x = 2.25

XY = x - x

= 2.25 - 2.25

= 0

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)
