Hi, thank you for posting your question here at Brainly.
The general equation of a horizontal ellipse is
(x-h)2/a2 + (y-k)2/b2 = 1, at center (h,k) while a = semi-major axis, b = semi-minor axis. These are related through the distance of the focus from the center,c. a2 = b2 + c2.
If you draw the points on a coordinate plane, the center of the ellipse is at (0,0), so h and k equals 0. Then, the minor axis (2b) spans from 8 to -8 of the y-axis. This is equal to 16 units. Hence,
2b = 16
b = 8
b^2 = 64
The distance between the two foci is 2c. Thus,
2c = 12
c = 6
c^2 = 36
Then, a2 = 64 + 36 = 100. Substituting to the general equation:
x^2/100 + y^2/64 = 1
Answer:
A solid formed is described when its resistance is tightly secured, and when it refuses to change shapes. It is one of the four fundamental elements. The best answer would be: The atoms are packed together and cannot move around.

Step-by-step explanation:
Answer:
The minimum is -5
The range is 
f(14) = 2739
Step-by-step explanation:
Given
Solving (a): The minimum
A quadratic function is represented as:
If a > 0, then the function has a minimum
By comparison
--- the function has a minimum
To calculate the minimum, we first calculate the following is calculated as:
So, we have:
So, the minimum is at f(m)
We have:
Solving (b): The range
In (a), we have:
--- the minimum
This implies that the smallest value of y on the graph is -5.
So, the range is:
Solving (c): f(14)
We have:
So:
