Answer:

Step-by-step explanation:
Given an hyperbola with the following conditions:
- Foci at (-10,0) and (10,0)
- x-intercept +/- 6;
The following holds:
- The center is midway between the foci, so the center must be at (h, k) = (0, 0).
- The foci are 10 units to either side of the center, so c = 10 and

- The center lies on the origin, so the two x-intercepts must then also be the hyperbola's vertices.
Since the intercepts are 6 units to either side of the center, then a = 6 and 

Therefore, substituting
and
into the standard form

Answer:
-125
Step-by-step explanation:
sea level is zero so cant be above that and the answer has to be below -100 and the only option is -125
Answer:
29
Step-by-step explanation:
You need to find the average number of students
Add up all the students
27+31+28+33+26
145
Divide by the number of classes
145/5
29
The average is 29
The correct answer is the last one - It will not be spread out across the entire coordinate plane because in Step 4 and Step 5, Sharon selected incorrect scales on the axes
