An ellipse passes through the points 9 0 and 6 12 and is in
An ellipse passes through the points (9, 0) and (6, 12) and is in standard postion.
 
Assuming the equation of the ellipse is in the form
x^2/c^2 + y^2/d^2 = 1
then
c =
d =
Assuming the equation of the ellipse is in the form
x^2/c^2 + y^2/d^2 = 1
then
c =
d =
Solution
substituting (9, 0) in the given equation we get
 
 81/c^2 =1
 =>c= 9
 
 
 substituting (6, 12) in the given equation we get
 
 36/c^2 + 144/d^2 =1
 =>36/81 + 144/d^2 =1
 =>144/d^2= 45/81
 
 =>d^2 = 144*9/5
 =>d = 36/5
this is the correct answer pls rate A+
