Answer:
Option d. (-2,-5)
Step-by-step explanation:
we know that
The equation of a vertical parabola in vertex form is equal to
where
a is a coefficient
(h,k) is the vertex of the parabola
In this problem we have
This is the equation of a vertical parabola open up
The vertex is minimum
Convert the equation in vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
-----> equation in vertex form
therefore
The vertex is (-2,-5)

Answer:
8
Step-by-step explanation:
SW and UW are equal because they are at the midpoint . A midpoint is a point on a line segment that divides it into two congruent segments.
The area of regular polygon with 5 sides is 689.65m²
<u>Explanation:</u>
All sides of a regular polygon are equal in length. If you know the length of one of the sides, the area is given by the formula:
where
s is the length of any side
n is the number of sides
tan is the tangent function calculated in degrees
Let the number of side of a polygon be 5. So, putting the values in equation
Therefore, the area of regular polygon with 5 sides is 689.65m²
