PLEASE HELP ME ASAP I HAVE A TEST DUE IN 30 MINS
I WILL DO BRAINLESIT TOO
please do all 3 questions

a) 9,12,15

b) 10.4

c) -3/2

Step-by-step explanation:

Step 1 :

a)

If the square of the highest length of line equals the sum of square of the other 2 length, then the 3 length can form a right triangle

Using this ,

1) 9,12,15

Hence this forms a right triangle

2)3,5,7

Hence this cannot form a right triangle

3)5,7,8.9

This cannot form a right triangle

4)2,9,11

Hence this cannot form a right triangle

Step 2 :

Length of the given line segment can be found using

So for the given points the length is

  = 10.4

Step 3 :

The slope of the given line is

m = (-7-(-4)/5-3 = -3/2

Let represent 1/6 of the course. Then the obstacles will appear as

{T} {T,C} {T,H} {T,C} {T} {T,C,H} [end of course]

A cone will appear with every other tire.
A hurdle will appear with every third tire.
