Three line segments can form a triangle if the length of the longest segment is greater than the sum of the lengths of the shorter segments.

They can form a triangle.
Now if c is the length of the longest side and a and b are the lengths of the shorter sides, then:
- if

, the triangle is right
- if

, the triangle is acute
- if

, the triangle is obtuse

The triangle is obtuse.
The answer is D.
Answer:
a) The vertex of the graph is
, b)
, c) The equation of the parabola is
.
Step-by-step explanation:
a) The tennis ball experiments a free fall, that is, an uniform accelerated motion due to gravity and in which effects from Earth's rotation and air viscocity are negligible. The height of the ball in time is represented by a second order polynomial. Hence, the vertex of the parabola is the initial point highlighted in graph.
The vertex of the graph is
.
b) If we know that
,
and
, then the value of
is:




c) The equation of the parabola is
.
18 divided by 30 equals .6
0.6=60%

For this case we must find the perimeter of the fence, in a circular way, knowing that the perimeter of a circle is given by:

Where "r" represents the radius of the circle, in this case 
Substituting in the perimeter equation we have:

Rationalizing we have:

Taking out common factor
