Identify a chord in the diagram shown.
A) DE
B) DC
C) BF
D) BC

DE

Step-by-step explanation:

A chord is a random line connecting from one end of the circle to another, but not from the center.

BC aren't even connected.

DC aren't connected either.

BF is what we call radius. From one end of the circle to the center.

Only DE makes sense.  

what are you trying to solve here

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)
