Why is Mrs. Chisholm certain of her decision?   <---- what decision?

anonymous · Answer

Mr. Hewitt, Mrs. Hoffman, and Mrs. Chisholm are engaged in a laser tag battle.  Their lasers have a maximum range of 16 feet.  This is the final showdown and whoever takes Mr. Hewitt out this round will forever be “The Victor” (a great honor among laser tag playing teachers)!  Because Mr. Hewitt can’t lose unless he is tagged, he finds solid cover and sits tight while Mrs. Chisholm and Mrs. Hoffman seek him out.  

The laser tag arena has green laser lines that, the teachers notice, create a coordinate grid of the playing field.  It has come down to the final moments and Mr. Hewitt is caught unaware that Mrs. Hoffman and Mrs. Chisholm each have a direct line to where he stands, but for Mrs. Chisholm to take the shot, she will have to give up her cover.  Mrs. Hoffman has not yet seen her, but the moment she steps out to get Mr. Hewitt, that Mrs. Hoffman will try to eliminate her from the field, so she must carefully weigh her next move.  She thinks for a moment and then BOLDLY steps forth to take the shot!

Perhaps you should try contacting your teacher.  Why do you feel the need to cheat?

Seriously though.  You've been waiting for 5 days for someone to give you the answer.  Why don't you just call you teacher to get help and maybe learn something while you are at it?

Since the maximum range of the lasers is 16 feet we simply need to discover if the lovely Mrs. Hoffman is within range or not. 
By using the formula, (x1-x2)<r<(y1-y2) and plugging in the values we will see:
(8--3)<r<(13-1)
11<r<12
Since 16 is not between 11 and 12, Mrs. Chisholm is not actually safe and she should NOT blow her cover! This question was tricky.
