The starting point is 4 and the slope is 2/1 (up 2 to the right 1)
Answer:
5 feet
Step-by-step explanation:
We are given that
Width of rectangular pool=b=30 feet
Length of rectangular pool=l=40 feet
Area of rectangle=
Using the formula
Area of rectangular pool=
Total area enclosed within the perimeter of the deck=
Width of deck=x ft
Length of rectangular pool including wooden deck=40+2x ft
Width of rectangular pool including wooden deck=30+2x ft
Area of rectangular pool including wooden deck=
According to question
(Dividing by 4 on both sides)
It is not possible because width cannot be negative it is always natural number.
Hence, the width of the deck=5 ft
Answer:
x-axis =
y-axis =
Line x =3 :
Line x = 6 :
Step-by-step explanation:
Given lines : y = √x
y = 0
x = 3
To determine the volumes generated we will use the disk method for each of the lines,
attached below is the detailed solution for line x =3 , same procedure will be repeated for each value of x and y to obtain the given results
The volume generated ( x axis )
=
volume generated ( y _axis )
=
Volume about x = 3
=
Volume about x = 6
=
