Is it possible for a composite number to have more than one prime factorization? Is it possible for a number to have no prime fa
Nitella [24]
Prime factors are factors of a composite number that are indivisible except by the number 1 or the number itself. The answers to your questions are the following:

1. Yes, it is possible especially for very large numbers. 
2&3. No, because as mentioned previously, the default prime factors of numbers are 1 and the number itself. For example, 2 is a prime number. Its factors are 1 and 2.
4. Prime factorization are useful in fields of encryption. They make use of the basic prime numbers for the arithmetic modulus with the general equation: n=pq.

calculate the unit rate of change for each linear function using the formula. (4,9) (8,12) (16,18) (32,30)
jenyasd209 [6]

Answer:

The unit rate of change is of \frac{3}{4}

Step-by-step explanation:

We are given a set of points (x,y).

To find the unit rate of change, we take two points, and divide the change in y by the change in x.

Points (4,9) and (8,12)

Change in y: 12 - 9 = 3

Change in x: 8 - 4 = 4

Unit rate of change: \frac{3}{4}
