Which graph represents the hyperbola?

x^2/5^2 - y^2/4^2 = 1

Step-by-step explanation:

The given formula is

Notice that the negative variable is , that means the hyperbola is horizontal. Also, its focal poitns are on the x-axis and have the form and .

Remember that the parameter is always with the positive varible. So,

The asymptotes are

and , replacing parameters, we have

and

So, the hyperbola is shown in the image attached, there you can observe that the vertices are and , which matches the parameter .

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

your answer would be 12
