Answer:
The polynomial is:
Step-by-step explanation:
Zeros of a function:
Given a polynomial f(x), this polynomial has roots such that it can be written as:
, in which a is the leading coefficient.
Zeros of −3, −1, and 2
This means that . Thus
Passes through the point (1,12).
This means that when . We use this to find a.
Thus
Answer:
∴73,563 calls are made between two cities with populations of 100,000 and 160,000 that are 435 miles apart.
Step-by-step explanation:
Given that,
The number of phone calls between two cities (N )
Given that,
N=18,000, d=310 miles, =15,500 and
=180,000
Now,
N=? , d=435 miles, =100,500 and
=160,000
∴73,563 calls are made between two cities with populations of 100,000 and 160,000 that are 435 miles apart.
