Can someone please prove that the expression (x-y)+(y-z)+(z-x) is equivalent to 0

see below

Step-by-step explanation:

Hence the nature of graph i.e the slope ,stiffness and nature will depend upon the number 3

Step-by-step explanation:

Given:

V(t)=2(3)t

To Find:

What number in function  3 indicates.

Solution:

This function is related to the  Growth of virus (population growth)

Population are generally exponential as follows:

Y=Y0e^(kt)

here

Y=present or on "t"year value.

Y0= value at that particular year

e is the  how graph is going to follows as per time period.

k= time constant .

t= time period.

Comparing given equation with the exponential growth,

Y=V(t)

Y0=2

e is represented  by 3

As e is irrational number  we cannot express in p/q form but we 3 can expressed in p/q.
