Answer:
No, it is NOT a function. 
Step-by-step explanation:
A functions' inputs are assigned to exactly one output.
We are given the points:
{(8,2) (4,-3) (6,4) (8,1)}
The input of 8 is repeating. 
The given relation is not a function.  
Hope this helps!

Altitude- Makes a right  angle
1. Splits the side. Median
2. Makes a right angle. Altitude
3.  Makes a right angle. Altitude

Answer:
80 mm
Step-by-step explanation:
Pythagorean theorm can be applied here to solve for the length of the last leg, 
 + 
 = 
, where (a) and (b) are the legs of the triangle and (c) is the hypotenuse. We can rearrange the pythagorean theorm for our purposes like the following: 
b = √c^2 - √a^2
   = √(82)^2 - √(18)^2
   = √6724 - √324
   = √6400
   = 80 mm
