Answer:

Step-by-step explanation:

-1.5(4-R)=12 divide both sides by -1.5

4-R=12/-1.5 calculate

4-R= -8 subtract 4 from both sides

-R=-8-4 calculate

-R=-12 multiply by -1

R=12

A box is contructed out of two different types of metal. the metal for the top and bottom, which are both square, costs $3 per s
zysi [14]

Let x ft be the length of the base square and y ft be the height of the box.

The volume of the box is

V=x\cdot x\cdot y\ ft^3.

Since the box has a volume of 15 cubic feet, then

x^2y=15,\\ \\y=\dfrac{15}{x^2}.

You need to construct two squares from the metal that cost $3 per square foot.

The area of each square is x^2\ ft^2 and the total cost for these two squares is 2\cdot x^2\cdot 3=6x^2.

The area of each side face is x\cdot y=x\cdot \dfrac{15}{x^2}=\dfrac{15}{x}. Then the total cost for sides is 4\cdot \dfrac{15}{x}\cdot 10=\dfrac{600}{x}.

Let S(x) be the function that represents total cost of the box, then

S(x)=6x^2+\dfrac{600}{x}.

Find the derivative:

S'(x)=12x-\dfrac{600}{x^2}.

When S'(x)=0, then 12x-\dfrac{600}{x^2}=0,\\ \\12x^3=600,\\ \\x^3=50,\\ \\x=\sqrt[3]{50}\ ft.

The dimensions of the box are:

length and width - \sqrt[3]{50}\ ft

height - \dfrac{15}{\sqrt[3]{2500}}\ ft.
