Which expression gives the length of the transverse axis of the hyperbola
1 answer:
Answer:
Option (B)
Step-by-step explanation:
From the picture attached,
F1 and F2 are the focii of the hyperbola.
Point P(x, y) is x units distant from F1 and y units distant from the other focus F2.
By the definition of a hyperbola,
"Difference between the distances of a point from the focii is always constant and equals to the measure of transverse axis."
Difference in the distances of point P from focii F1 and F2 = (x - y) units
This distance is equal to the length of the transverse axis = (x - y) units
Therefore, Option (B) will be the answer.

The percentage change from the number of park visitors on Saturday
to the number of park visitors on Sunday is 37.5%
Step-by-step explanation:
The percentage of change from A to B is:
The percentage of change = × 100%
The manager of an amusement park recorded the number of visitors
to the park
- There were 800 visitors on Saturday
- There were 1,100 visitors on Sunday
We need to find the percentage change from the number of park
visitors on Saturday to the number of park visitors on Sunday
∵ The number of park visitors on Saturday = 800
∵ The number of park visitors on Sunday = 1,100
- Use the rule of the percentage change above
∴ The percentage change from the number of park visitors on
Saturday to the number of park visitors on Sunday =
× 100%
∴ The percentage of change = 37.5%
The percentage change from the number of park visitors on Saturday
to the number of park visitors on Sunday is 37.5%
