Answer:
The answer is 19.20 inches
Step-by-step explanation:
Given is :
The tank is a 5-gallon cylindrical container with a height of 2 feet and a radius of 4 inches.
The inch measurement along the height of the tank is as 2 feet for 5 gallons, or 2.5 gallons per foot.
So, volume per inch is = gallons per inch.
Now the volume calculation according to the geometric cylinder shape is not necessary.
After the 1 gallon was removed, the water level will be at:
=
= inches.
Firstly, we will select three corner points
A=(2,3)
B=(6,8)
C=(7,4)
we are given
the transformation with the rule (x, y)→(x, −y)
y--->-y
so, it is reflected about x-axis
so, we will multiply y-value by -1
we get new points as
A=(2,-3)
B=(6,-8)
C=(7,-4)
now, we can locate these points and draw graph
we get
