The general form of the quetion of a circle is ax^2+by^2+cx+dy+e=0 where a=b=0 if the circle has a radius of three units and the center lies on the y axis which set of values of a, b, c, d, and e might correspond to the circle

a =1 ,b =1 ,c =0 , d =-2k  and e =

Step-by-step explanation:

Equation of circle with radius 3 units and center on Y axis is always of the form

where  r = 3

on simplifying it we get

=0

on comparing it with given general equation we get

a =1 ,b =1 ,c =0 , d =-2k  and e =

where k can be any real number

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
