See attached for a sketch of some of the cross sections.
Each cross section has area equal to the square of the side length, which in turn is the vertical distance between the curve y = √(x + 1) and the x-axis (i.e. the distance between them that is parallel to the y-axis). This distance will be √(x + 1).
If the thickness of each cross section is ∆x, then the volume of each cross section is
∆V = (√(x + 1))² ∆x = (x + 1) ∆x
As we let ∆x approach 0 and take infinitely many such cross sections, the total volume of the solid is given by the definite integral,
Answer: $80
Step-by-step explanation:
Given: The amount earned by Fadil on selling 14 televisions= $1400
Therefore, the amount he earned on selling 1 television=
Since, he sold televisions with extended warranty and he earns $20 additional for it.
Then, the fixed amount Fadil earns for each television=
Hence, Fadil earns $80 as the fixed amount for each televison.
