What is the domain of the function y = ln ((-x+3)/2)

The Domain is x < 3

Step-by-step explanation:

We know that ln(x) is defined for all real numbers that are greater than zero, or x > 0.

Knowing that we must make the inside of ln(x) greater than 0 so:

Multiply both sides by 2:

Add x to both sides:

or

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
