Okay so my teacher gave me this homework assignment.
I HAVE NO CLUE HOW TO DO IT.
So mind helping mee?
Here's the question.

The table below shows temperature at various heights above omaha,Nebraska.The measurements were made on a January day when the temperature at ground levek was 32 degress F.Reminder: 1 mile=5,280 ft.(if you have a everyday mathematics student math journal for grade sixth its on page 21.)Also, f below this message means degrees fareinheight.

Here's the table,
Height above ground(miles):
0(ground level)temp:32F
1 temp:25F
2 temp:15F
3 temp:-5F
4 temp:-25F
4.5 temp:-40F
5.5 temp:-60F
10 temp:-75F

Then it told me I had to make a broken line graph.
Then there were these following questions:

2.At about what height above the ground was temp. 0F?
3;What was the approximate temp. 8 miles above omaha?
4.Suppose an airplane was about 26,000 feet above omaha on the day recorded in the table.
a.What was the approximate temp. at 26,000 ft above ground level?


I'm really confused!
Help!:confused: :confused:

If you draw a graph connecting the data points that you were given, you'll get a series of straight lines connecting the points. To estimate the temp for an altitude that isn't listed in the table, you interpolate between the points that you know on either side. For example, to find the altitude whet T = 0, you know it falls somewhere between 2 and 3 miles. Since the temp drop between 2 and 3 miles is a total of 20 degrees (15 minus -5 = 20), that means that the point you'relooking for that corresponds to 0 degrees is 15/20 of the way between 2 miles and 3 miles. Does that make sense? You can handle the other problems in a similar way.
