The perimeter may not be small enough to measure with just a ruler. For example, if a side of a rectangle was 30 inches, how would you use a 12 inch ruler to accurately measure that side? Also, if you were measuring a shape like a circle or oval, a tape measure is flexible.
Answer:
The answer would be -4.36.
By first principles, the derivative is
Use the binomial theorem to expand the numerator:
where
The first term is eliminated, and the limit is
A power of 
in every term of the numerator cancels with in the denominator:
Finally, each term containing approaches 0 as 
, and the derivative is
Answer:
Degree
Step-by-step explanation:
Answer:
3 vertices
Step-by-step explanation:
Vertices are the "points" of a 2D figure. In this case, we see the 2D figure as a triangle. There are 3 points on the triangle, so there are 3 vertices.
