Answer:
7.07
Step-by-step explanation:
<h2><u>Length</u></h2>a square has equal length on each side
hence is the perimeter is 20 it means that :
each side is 20/4 = 5
we can make a diagonal line which create 3 right angled triangles
2 sides of the triangle are 5 , this is the base and the height
to find the length we can make use of the Pythagoras theorem
c^2 = a^2 + b^2
c is the hypotenuse ( the diagonal;)
a and b are the opposite and adjacent
hence :
c^2 = 5 ^2 + 5^2
c^2 = 50
c =
c = 7.071

<h3><u>diagonal length = 7.07</u></h3>
Answer:
The midpoint M is (5,7)
Step-by-step explanation:
U(8,9)
V(2,5)
m = [(8+2)/2 , (9+5)/2]
= [(10/2) , (14/2)]
= (5,7)

For 
to be continuous at 
, we need to have
Note that
means that 
, but that 
is *approaching* 5. We're told that for , we have
We can write
and the limit would be
and so is discontinuous.
