Answer: ![x^{2} = 20y](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%20%3D%2020y)
Step-by-step explanation:
The directrix given is vertical , so we will use the formula :
![(x-h)^{2}=4p(y-k)](https://tex.z-dn.net/?f=%28x-h%29%5E%7B2%7D%3D4p%28y-k%29)
P is the distance between the focus , that is 5 - 0 = 5
Therefore : p = 5
(h,k) is the mid point between the focus and the directrix , that is
(h,k) =
=
= ![(0,0)](https://tex.z-dn.net/?f=%280%2C0%29)
Therefore:
h =0
k = 0
substituting into the formula : we have
![(x-h)^{2}=4p(y-k)](https://tex.z-dn.net/?f=%28x-h%29%5E%7B2%7D%3D4p%28y-k%29)
= 4(5)(![y-0)](https://tex.z-dn.net/?f=y-0%29)
![x^{2} = 20y](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%20%3D%2020y)
Therefore : the equation in vertex form is ![x^{2} = 20y](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%20%3D%2020y)
2.5*d+5= 65
subtract 65 by 5 and divide by 2.5 to get the number of days shes had the plant :)
