Answer:
TS, SR, and TR are all co-linear
Step-by-step explanation:
Regardless of where the points lie, you can connect a line segment from point T to point S, so TS are co-linear
The same goes for point S to point R
The same goes for point T to point R
The definition of a line is the shortest distance through 2 points in space, so you can make a line between any 2 points.
Answer:
deepest part of dive is 2.5 feets below sea level ;
-2.5 feets
Step-by-step explanation:
Given :
Initial Position = 5.8 feets above sea level = +5.8
Deepest part of dive = x
Change in elevation between initial position and deepest part of dive = 8.3 feets
Position relative to sea level at deepest part of dive :
x = change in elevation - Initial position
x = 8.3 feets - 5.8 feets
x = 2.5 feets
Hence, deepest part of dive is 2.5 feets below sea level

You always do the estimating first. That way, you'll know
if your answer makes sense. If not, you know right away that
you made a mistake in adding.
When I look at these numbers, I make the first one about 365 thousand
and the second one about 6 thousand.
I add those in my head, and I estimate that the sum is going to be
about 371 thousand.
Now I pick up my pencil and add the numbers. I get 358,643 .
This is not good. Something went wrong. That's nowhere near my estimate.
I must have made a mistake. I'll have to try again.
This time I put the numbers into my calculator and add them.
I get 371,109 . This is very near my estimate, so I accept it.
I look back at my work on paper, to see if I can spot my mistake there.
Yep ... there it is. On paper, I subtracted the numbers instead of adding.
The estimate ... which I did FIRST ... told me when my answer was
wrong, and when it was right.
