Answer: 14cm
Step-by-step explanation:
The diameter of a circle is twice the radius.
Therefore, the diameter = 2*7 cm = 14cm

The center of the hyperbola is the midpoint of its foci. The distance between the foci is 43-9=34. So they're 17 from the center.
We have coordinates
F1(0,17)
F2(0,-17)
Let's call the vertex of the hyperbola V. We have
V(0,13)
This is a vertical hyperbola so the equation is of the form
The vertices for a vertical hyperbola like this are (0, a) and (0,-a)
So we have a=13
The distance c from the foci to the center is given by
That says our hyperbola's equation is
That's our answer.

Answer:
B
Step-by-step explanation:
We require 2 equations in 2 variables
let x be the number of salads sold and y the number of drinks sold, then the 2 equations are
x + y = 209 → (1)
6.5x + 2y = 836.5 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate y
- 2x - 2y = - 418 → (3)
Add (2) and (3) term by term
(6.5x - 2x) + (2y - 2y) = (836.5 - 418) ← simplify
4.5x = 418.5 ( divide both sides by 4.5 )
x = 93
The number of salads sold was 93
