Starks sculpture 30 cubed is a cube with sides 30 inches long. Whats its volume​
Zolol [24]

Answer: 27000\text{ cubic inches}

Step-by-step explanation:

Given : Starks sculpture 30 cubed is a cube with sides 30 inches long.

We know that the volume of a cube is given by :-

\text{Volume}=(side)^3

Then , the volume of Starks sculpture 30 cubed will be :

\text{Volume}=(30)^3\text{ cubic inches}

\text{Volume}=30\times30\times30\text{ cubic inches}

\text{Volume}=27000\text{ cubic inches}

Hence, the required volume = 27000\text{ cubic inches}

HELP PLEASE, Domain and range problem
pentagon [3]

Answer:

Range is number of copies produced and set of values is; 1 ≤ N ≤ 200

Domain; Cost of publishing book in dollars; set of values are; $710 ≤ N ≤ $2700

Step-by-step explanation:

Range is a set of all the possible output values in a function while domain is the set of all possible input values.

Now, the function is given as;

C = 10N + 700

Where;

C is the cost of publishing the book in dollars

N is the number of copies of books produced

Thus, the domain will be a set of N values while Range will be a set of C values.

We are told that the first printing can produce up to 200 copies of the book.

That means a maximum of 200 books and a minimum of 1.

Thus;

Range is; 1 ≤ N ≤ 200

Maximum possible cost of the 200 books is;

C = 10(200) + 700

C = $2700

Minimum cost which will be for 1 book will be;

C = 10(1) + 700

C = $710

Thus,domain is;

$710 ≤ N ≤ $2700
