So for the first one I am guessing it is a type of dog, like a long dog. Maybe an Duchsand dog. Thats my guess.

For the second I have no idea.

The third I am thinking that the man did not want to die so there was a reason he had to run 15 feet then jump. Maybe there was some way out he could only get to if he ran those 15 feet. Maybe a door. Or he was in a tunnel or a bridge. If it was a tunnel and the quickest way to get out was the way in then that might be it. Or maybe it was a brigde plus a tunnel. Idk.

Am I wrong?

First one

Avg rate of change from 0 to 2

We have the points at x = 0 and x = 2 of (0, 2) and ( 2, 1)

The average rate of change is just the slope between these points =

[ 1 - 2 ] / [ 2 - 0 ] = -1 /2

Second one

Avg rate of change on [ 3, 5 ]

We have the points ( 3,59) and (5,53)

The avg rate of change is just the slope between the points =

[ 53 - 59 ] / [ 5 - 3 ] = -6 / 2 = -3

Last one

We have the points ( 1, 484) and ( 4,244)

Avg rate of change = [ 244 - 484 ] / [ 4 - 1 ] = -240 / 3 = -80

Imagine the angle between the two sides to be 1^o - the 9" side would extend 3" past the 6" side. Since the answers are rounded, the third side could be 3"

Now consider that angle to be 179^o - the third side would be 9" plus 6" which is 15"

Mentally view the 9" side swinging in an arc from the 1^o position to the 179^o position. The third side can be any length between the extremes.

so the answers are between 3" and 15" - therefore 10, 7, 4, 15, and 12.

There is a specific theorem thats could help, its called the triangle inequality therom. So you cannot have the third side of your triangle must be greater than the difference of the two other sides. And also smaller than the sum of the two sides so.

If you subtract 9 and 6 you get 3. So E.2 Is off the table. Since it is lower.

If you add 9 and 6 you get 15. So D.15 is off the table. Since it is equal to or greater than the combination of 9 and 6.

So the answers you have left are A.10, B.7, C.4, F.12. Since they are in between the diference of (9-6) and the addition of (9+6).

Hope this helps ;P

This must pass the Triangle Inequality....thus....

6 + missing side > 9

missing side > 3
