Use strong mathematical induction to prove the existence part of the unique factorization of integers theorem (Theorem 4.4.5). I
valentina_108 [34]

Answer:

Lets say that P(n) is true if n is a prime or a product of prime numbers. We want to show that P(n) is true for all n > 1.

The base case is n=2. P(2) is true because 2 is prime.

Now lets use the inductive hypothesis. Lets take a number n > 2, and we will assume that P(k) is true for any integer k such that 1 < k < n. We want to show that P(n) is true. We may assume that n is not prime, otherwise, P(n) would be trivially true. Since n is not prime, there exist positive integers a,b greater than 1 such that a*b = n. Note that 1 < a < n and 1 < b < n, thus P(a) and P(b) are true. Therefore there exists primes p1, ...., pj and pj+1, ..., pl such that

p1*p2*...*pj = a

pj+1*pj+2*...*pl = b

As a result

n = a*b = (p1*......*pj)*(pj+1*....*pl) = p1*....*pj*....pl

Since we could write n as a product of primes, then P(n) is also true. For strong induction, we conclude than P(n) is true for all integers greater than 1.

in a Recipe, 125 ml of milk is used for every half litre of water what is the ratio of milk to water​
yanalaym [24]

Answer:

1 : 4

Step-by-step explanation:

half litre = 500 ml

Milk : water = 125 : 500

                   = 125 ÷ 25  : 500÷25

                   = 5 : 20

                    = 1 : 4

3 folders cost $2.91 which equation would help determine the cost of 2 folders
eimsori [14]

Answer:

The equation that will determine the cost of two folders is;  3x = 2× $2.91

and  the cost of  the 2 folders is $1.94

Step-by-step explanation:

To solve this problem, we will follow the steps below;

Using proportion;

Let x be the cost of 2 folders

3 folders = $2.91

2 folders  =  x

Cross-multiply

3x = 2× $2.91

The equation that will determine the cost of two folders is

3x = 2× $2.91

We can go ahead and solve

3x = $5.82

Divide both-side of the equation by 3

\frac{3x}{3}  =  \frac{5.82}{3}

x = $ 1.94

The cost of 2 folders is $1.94
