Step-by-step explanation:
we know that
The standard form of a vertical parabola is equal to

where
(h,k) is the vertex
the focus is (h, k + p)
and
the directrix is y = k - p
Part 1) we have

Convert to standard form

The vertex is the point 


the directrix is equal to

Part 3) we have

Convert to standard form

The vertex is the point 


the directrix is equal to
----->
Part 4) we have

Convert to standard form

The vertex is the point 


the directrix is equal to

9 × n - 20 = 16
9n - 20 = 16
+ 20
9n = 36
÷ 9
n = 4

Answer:
8 + 5 = 13 apples
Step-by-step explanation:
The words "in all" mean addition. Therefore, 8 apples plus 5 apples equals 13 apples.
Answer:
For a green and a blue P1 = 8/11 * 3/10 = (80 * 33) / 110^2 = .218
For a blue and a green P2 = 3/11 * 8/10 = (30 * 88) / 110^2 = .218
The probabilities are the same
