Ronch [10]3 years ago
6 0

Answer:

x = 15

Step-by-step explanation:

To find the x-intercept(s), substitute in  0  for  y  and solve for x.

0 = 1/3 x − 5

Solve the equation.

x  =  15

This is so it makes more sense for u

You have asked to design a rectangle box with a square base and an open top. The volume of the box must be620 cm to the 3rd powe
hammer [34]

Answer:

$69.21

Step-by-step explanation:

Since the box has a square base the length and breadth of the box will be equal. Let it be x

Let h be the height of the box

V = Volume of the box = 620\ \text{cm}^3

x^2h=620\\\Rightarrow h=\dfrac{620}{x^2}

Now surface area of the box with an open top is given

s=x^2+4xh\\\Rightarrow s=x^2+4x\dfrac{620}{x^2}\\\Rightarrow s=x^2+\dfrac{2480}{x}

Differentiating with respect to x we get

\dfrac{ds}{dx}=2x-\dfrac{2480}{x^2}

Equating with zero

0=2x-\dfrac{2480}{x^2}\\\Rightarrow 2x^3-2480=0\\\Rightarrow x^3=\dfrac{2480}{2}\\\Rightarrow x=(1240)^{\dfrac{1}{3}}\\\Rightarrow x=10.74

Double derivative of the function

\dfrac{d^2s}{ds^2}=2+\dfrac{4960}{x^3}=2+\dfrac{4960}{1240}\\\Rightarrow \dfrac{d^2s}{ds^2}=6>0

So, x at 10.74 is the minimum value of the function.

h=\dfrac{620}{x^2}\\\Rightarrow h=\dfrac{620}{10.74^2}\\\Rightarrow h=5.37

So, minimum length and breadth of the box is 10.74 cm while the height of the box is 5.37 cm.

The total area of the sides is 4xh=4\times 10.74\times 5.37=230.7\ \text{cm}^2

The area of the base is x^2=10.74^2=115.35\ \text{cm}^2

Cost of the base is $0.40 per square cm

Cost of the side is  $0.10 per square cm

Minimum cost would be

230.7\times 0.1+0.4\times 115.34=\$69.21

The minimum cost of the box is 69.21 dollars.
