The postal service charges $2 to ship packages up to 5 ounces in weight, and $0.20 for each additional ounce up to 20 ounces. After that, they charge $0.15 for each additional ounce. What is the domain of this relation?

 x > 0   x = (0, ∞)

Step-by-step explanation:

The domain (x-values) are the number of ounces the package weighs.

The package must weigh greater than 0 but there doesn't appear to be a maximum weight. Therefore, x > 0

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368

answer: i believe it is c

step-by-step explanation:

because 5+4=9 so it would be 3^9
