PLEASE HELP AND DONT GUESS

Step-by-step explanation:

√12

Try putting it in your calculator. What digit comes next? Any number you pick from 0 to 9 is a guess. That's one of the ways you can tell if a number is irrational or not. You could get the answer from the calculator that came with windows. It gives the answer to 18 digits, but you'd still be guessing the 19th one.

The others are all well behaved in comparison.

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

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
