The required equation of the hyperbola is expressed as
The standard form for calculating the equation of a parabola along the x-axis is expressed as:
where:
(h, k) is the center
(k±c, h) are the foci
is the directrix
From the question given, we can see that foci = (±5, 0)
k±c, h = ±5, 0
k = 0
h = 0
c = 5
From the directrix,
Also, we need to know that;
a²+b² = c²
10 + b² = 5²
b² = 25 - 10
b² = 15
Substituting the gotten values into the equation of a hyperbola;
This gives the required equation of the hyperbola

Answer:A General Note: Rate of Change
The average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.
Step-by-step explanation:
<span>Without the diagram, there are 6 possible arrangements for points E, D, H. Let's see if we can reduce that to something smaller. HD can not be parallel to either TV or UV since it would have to be half of either of those sides in length. So HD has to be parallel to side TU. This means that point E has to be the midpoint of side TU. However, it's indeterminate about which point is H, or which point is D. Therefore there's 2 possible answers to this question. Without the diagram, it's impossible to determine which of the two possibilities is correct, so you'll have to choose the correct one yourself.
Option 1. D is midpoint of TV, H is midpoint of UV.
Triangle TUV is similar to triangle DHV. Since the ratio of the corresponding sides is 2:1, the length of HE is half of the length of TV. So 100/2 = 50. And because of that 2:1 ratio, the length of TU is twice that of HD, so 2 * 80 = 160. In summary:
HE = 50
TU = 160
Option 2. H is midpoint of TV, D is midpoint of UV.
We still have a similar triangle, but H&D are swapped. The length of TU will be the same as in option 1 above. And the length of HE will be half that of UV instead of TV. So 80/2 = 40. So in summary:
HE = 40
TU = 160</span>
