Answer:
Only option A is correct.
Step-by-step explanation:
From the given figure it is noticed that the vertices of hyperbola are (0,8) and (0,-8). It is a vertical hyperbola.
It means a=8.
From the rectangle we can say that the value of b is 6.
The focus of a vertical hyperbola are (0,c) and (0,-c). So, the focus of hyperbola are (0,10) and (0,-10).
Therefore option A is correct.
Asymptotes of a vertical hyperbola are
Directrix of a vertical hyperbola are
Only option A is correct.
Answer:
10m
Step-by-step explanation:
Recall that the perimeter of a rectangle
= (2 x Long Side) + (2 x Short Side)
we are given that each of the long side = 20m and the perimeter is 60m
substituting these into the equation,
60 = (2 x 20) + (2 x Short Side)
60 = 40 + (2 x Short Side) (subtract 40 from both sides)
60-40 = (2 x Short Side)
(2 x Short Side) = 20 (divide both sides by 2)
Short Side = 20 / 2 = 10m
The answer to the question is .55. The line is a division sign, so all you need to do is divide the top number by the bottom number.
