Madeline is doing a presentation in class on the transportation systems of a plant. The plant she studied was small, so she used
a model to help describe the plant's systems. She explains that the plant's food, sugar, is produced in the leaves and is transported to the rest of the plant. Madeline also explains that water and minerals are absorbed by the roots. The diagram below shows the model she used for the presentation.
What is one disadvantage of using this model?
A.
The model does not show how the transportation systems interact with other parts of the plant.
B.
The model includes too much detail about the methods used to move resources in the plant.
C.
The model is too large to accurately represent the actual plant's transportation systems.
D.
The model cannot be used to describe the general direction that resources move.

Answer:
x^2+y^2+z^2-10x-6y-10z +50 =0
Step-by-step explanation:
Given that a sphere is contained in the first octant
Centre of the sphere is given as (5,3,5)
Since this is contained only in the first octant radius should be at most sufficient to touch any one of the three coordinate planes
When it touches we can get the maximum sphere
We find that y coordinate is the minimum of 3 thus radius can be atmost 3 so that then only it can touch y =0 plane i.e. zx plane without crossing to go to the other octants.
Hence radius =3
Equation of the sphere would be
