<u>Vertex form of the quadratic equation</u>
The vertex form of the quadratic function has the following equation:
Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.
The parabola is given as:
Comparing with the equation:
a=2, Vertex: (3,4)

Answer:
- The other leg is 82 units
------------------------
Given:
- a = 19,
- c =
,
- b = ?
Find the missing leg, using Pythagorean:
- a² + b² = c²
- 19² + b² = 7085
- 361 + b² = 7085
- b² = 7085 - 361
- b² = 6724
- b =
- b = 82
