Express the surface area of a cube as a function of its volume v state its domain

In this question , we have to express the surface area of a cube in terms of volume of the cube .

The formula of volume of cube with edge length s is

First we have to solve for s, by taking cube root to both sides. That is

And the formula of surface area of cube is

Substituting the value of s, we will get

THerefore,

Domain is related to Volume here.

And Volume cant be negative or 0. So the domain is all positive real numbers .

529 and 531

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
