Answer:
a=9.4 b=12.0
Step-by-step explanation:
You need to use Pythagorus
So for a:
8²+5²=89 a=√89=9.4
And b:
17²-12²=145 b=√145=12.0
A point is set up like (x,y)
Since horizontal movement is movement in the x-axis, the x part of the point would change.
Since horizontal changes appear as the opposite inside the parentheses, 9 units right would be -9
-3-9= -12
A change up or down is a change in the y-axis. So, 10 units down would be 15-10=5
So, the new point is (-12,5)
All you are basically doing is making ratios.
Basketball to football would be 5 to 11 or 5:11 or 5/11.
What you do is in the order you said it (basketball to football) you find that info and make it a ratio. A ratio must be simplified and can be written 3 ways, as shown above.
Hockey to lacrosse would be 6 to 10 and simplified would be 3 to 5.
Try doing 3 and 4 and 5 on your own to help you understand it more:) if you have any questions tell me.
