Answer:
The absolute change in the height of the water is 9.5 inches
Step-by-step explanation:
Given
--- length
--- width
--- height
--- the volume removed
Required
The absolute change in the height of the water
First, calculate the base area (b):



The height of the water that was removed is:
<em />
<em> i.e. the volume of the water removed divided by the base area</em>



The absolute change in height is:




Find the perimeter of the garden find out what kind of triangle the garden is for example if it is a right triangle it has to equal up to 90.
To find the area remember that A=b•h2 as a=area
Answer:
Step-by-step explanation:
The directrix is a vertical line, so the parabola is horizontal. The focus lies to the left of the directrix, so the parabola opens to the left.
For a left-opening parabola:
x = a(y-k)²+h,
a < 0,
vertex (h,k)
focal length p = 1/|4a|
focus (h-p, k)
directrix: x=h+p
Apply your data
focus (1,-4)
directrix x=2
vertex (1.5,-4).
focal length p = 0.5
a = -1/|4p| = -½
x = -½(y-2)²+ ½
