Answer:
I'm not 100% sure but it might be b
Step-by-step explanation:
The roots routine will return a column vector containing the roots of a polynomial. The general syntax is
z = roots(p)
where p is a vector containing the coefficients of the polynomial ordered in descending powers.
Given a vector
which describes a polynomial
we construct the companion matrix (which has a characteristic polynomial matching the polynomial described by p), and then find the eigenvalues of it (which are the roots of its characteristic polynomial)
Example
Here is an example of finding the roots to the polynomial
--> roots([1 -6 -72 -27])
ans =
12.1229
-5.7345
-0.3884
Answer:
Step-by-step explanation:
Let x is the total population of the world.
Therefore, by the condition given the population of North America is 
Again it is given that 
fraction of the world's population lives in the United States of America.
So, 
is the population of USA.
Therefore, the fraction of the population of North America that is the population of USA will be
