A circular hedge surrounds a sculpture on a square base. The radius of the hedge is 6x. The side length of the square sculpture

andrey2020 [161]

Hi, thank you for posting your question here at Brainly.

Since the hedge is surrounding the square base, the area of the base can be determined by subtracting the area of the base from the hedge.

A = pi*r^2 - (4x)^2
A = pi*(6x)^2 - (4x)^2
A = 2x^2*(3pi - 2)

I hope I was able to answer your question. Have a good day.

The graph of h(x) is a translation of f(x)=3 √x

Gnoma [55]

Answer:

$h(x)=\sqrt[3]{x+2}$

Step-by-step explanation:

we have

$f(x)=\sqrt[3]{x}$

The inflection point of f(x) is the point $(0,0)$

The inflection point of h(x) is the point $(-2,0)$ -----> see the given graph

so

the rule of the translation of f(x) to h(x) is

$(x,y)------> (x-2,y)$

That means------> The translation is $2$ units to the left

therefore

The equation of h(x) is equal to

$h(x)=\sqrt[3]{x+2}$
