Apostal delivery service charges $3.40 per package and then an additional $0.50 per ounce the package weighs. the function can be modeled by f(x)= 0.5 +3.4. tom ships 4 packages with the following weights: 2 ounces, 3.5 ounces, 15 ounces, and 21.3 ounces. write four statements using function notation that evaluate the function given each of these weights. interpret the results in terms of the context of the function.

The function you're to evaluate is

... f(x) = 0.5x +3.40

Using function notation, the value for x = 2 is ...

... f(2)

For x = 3.5, the value is ...

... f(3.5)

and so on.

To actually evaluate the function, you need to put the value where x is in the function definition and do the arithmetic:

... f(2) = 0.5·2 + 3.40 = 1.00 +3.40 = 4.40

The function gives the charge for a package based on its weight in ounces. The result of evaluating the function for the given weights is that you find the charges for delivery of those packages.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
