The fifth term of the geometric sequence would be 0.972
Sang grew more. and by 17/40 ( I could be wrong)
Answer:
It is c = kt.
Step-by-step explanation:
This is direct variation . As the time increases the number of cranes increases.
The equation is c = kt where k is the constant of variation. In this case it will be a positive value because c is increasing with time.
If they make 20 cranes in 10 minutes then we can find the value of k by plugging in these values;
20 = k * 10
g = 20/10
k = 2.
So they make 2 cranes per minute.
We have been given two polynomials 
Let us first multiply these polynomials.

Now, we know that polynomials follows closure property of multiplication.
It means that when we multiply two polynomials, the result will be a polynomial.
Since, when we multiplied the given polynomials, we got
which is a polynomial.
Therefore, the correct option is
The result
is a polynomial.
