Step-by-step explanation:
The equation is in the form ...
4p(y -k) = (x -h)^2 . . . . . (h, k) is the vertex; p is the focus-vertex distance
Comparing this to your equation, we see ...
p = 4, (h, k) = (3, 4)
p > 0, so the parabola opens upward. The vertex is on the axis of symmetry. That axis has the equation x=x-coordinate of vertex. This tells you ...
vertex: (3, 4)
axis of symmetry: x = 3
focus: (3, 8) . . . . . 4 units up from vertex
directrix: y = 0 . . . horizontal line 4 units down from vertex
Using the together rate, it is found that if Mrs Adams camps alone, she will use all the water in 24 hours.
<h3>What is the together rate?</h3>The together rate is the sum of each separate rate.
In this problem, the rates are:
- Together: 1/8.
- Mr Adam: 1/12.
- Mrs Adams: 1/x.
Hence:
If Mrs Adams camps alone, she will use all the water in 24 hours.
