Tell how you know when you have found the prime factorization of a number

Answers

When you come to a number that you can't divide any more
When you end up with prime numbers for example
If you factored out 12 you could say 3x4. Now 3 is a prime number so it cant be broken down any more. You can break down 4 into 2x2. 2 is a prime number so cant be broken down any further. When 12 is factored out it is 2x2x3

Percent of change 25 points to 50 points

Answers

percent change
first find change
then find as a percent out of original

percent mean parts out of 100 so x%=x/100

find change first

25 to 50 is a change of 25

now we do
change/original=x%
change/original=x/100
25/25=x/100
1=x/100
x=100


answer is 100% change

25 points to 50 points is a 100% change

100% of 25 = 25

25 + 25 = 50

100% is your answer

The function C(x) = 29x + 54.5 represents the cost (in dollars) of cable for x months, including the $54.50 installation fee. a. How much would you have spent on cable after 6 months?

b. How many months of cable service can you have for $344.50?

Answers

Answer:

a. \$228.5

b. 10 months.

Step-by-step explanation:

a. Given the function the following function:

C(x) = 29x + 54.5

 You can calculate the amount of money (in dollars) you would spent on cable after 6 months through this procedure:

- Substitute x=6 into the function:

C(6) = 29(6) + 54.5

- Evaluating, you get:

C(6) =228.5

b. The steps to calculate the number of months of cable service that you can you have for $344.50, are:

- Rewrite the function in this form:

y = 29x + 54.5

- Substitute y=344.50 into the function and then solve for "x":

344.50= 29x + 54.5\n\n290=29x\n\n(290)/(29)=x\n\nx=10
