1.18. A fish tank has a base, B, with an area, in square inches, modeled by B(x) = 2x + 6x + 4.
Alekssandra [29.7K]

Answer:

The volume of fish tank is V(x)=2x^3+12x^2+22x+12

Step-by-step explanation:

Area of Base of fish tank = Length \times Breadth

We are given that A fish tank has a base, B, with an area, in square inches, modeled byB(x) = 2x^2 + 6x + 4.

So,  Length \times Breadth =2x^2 + 6x + 4.

Height of tank = x+3

Volume of tank = Length \times Breadth \times Height

So, Volume of tank =(2x^2 + 6x + 4)(x+3)

Volume of Tank =2x^3+6x^2+4x+6x^2+18x+12=2x^3+12x^2+22x+12

Hence The volume of fish tank is V(x)=2x^3+12x^2+22x+12

Find the area of the regular polygon.
ad-work [718]

The area (A) of a regular hexagon in terms of its side length s is

... A = (3√3)/2·s²

For a regular hexagon, its side length is equal to the radius of its circumcircle, given here as 10√3 cm. Putting this value in the formula gives

... A = (3√3)/2·(10√3 cm)² = 450√3 cm²

... A ≈ 779.4 cm² . . . . area of the hexagon
