8.) Tina climbed up a ladder to the high-dive diving board at her community pool which is feet high. She dove off and when she landed in the pool, she was able to touch the very bottom which is   feet deep. Find the difference between the highest and lowest places Tina was throughout the dive.

I just want someone to help me understand better "Mapping". for exammple how should i map say this *see attachment* how exaclty should i write my mapping/ (x,y)-->(xsqrty) ? or like a table? idk why but maybe im just over thinking things

Determine how the following lines interact.

1. (x, y, z) = (-2, 1, 3) + t(1, -1, 5) ; (x, y, z) = (-3, 0, 2) + s(-1, 2, -3)

Can someone do this step by step? I'm confused how to do this, thank you!
