A cardboard box without a lid is to have a volume of 19,652 cm3. Find the dimensions that minimize the amount of cardboard used.
Effectus [21]

Answer:

The dimension of the cardboard is 34 cm by 34 cm by 17 cm.

Step-by-step explanation:

Let the dimension of the cardboard box be x cm by y cm by z cm.

The surface area of the cardboard box without lid is

f(x,y,z)= xy+2xz+2yz.....(1)

Given that the volume of the cardboard is 19,652 cm³.

Therefore xyz =19,652

\Rightarrow z=\frac{19652}{xy}......(2)

putting the value of z in the equation (1)

f(x,y)=xy+2x(\frac{19652}{xy})+2y(\frac{19652}{xy})

\Rightarrow f(x,y)=xy+\frac{39304}{y})+\frac{39304}{x}

The partial derivatives are

f_x=y-\frac{39304}{x^2}

f_y=x-\frac{39304}{y^2}

To find the dimension of the box set the partial derivatives f_x=0 and f_y=0.Therefore y-\frac{39304}{x^2}=0

\Rightarrow y=\frac{39304}{x^2}.......(3)

and   x-\frac{39304}{y^2}=0

\Rightarrow x=\frac{39304}{y^2}.......(4)

Now putting the x in equation (3)

y =\frac {39304}{(\frac{39304}{y^2})^2}

\Rightarrow y=\frac{y^4}{39304}

\Rightarrow y^3= 39304

⇒y=34 cm

Then \Rightarrow x=\frac{39304}{34^2} =34 cm.

Putting the value of x and y in the equation (2)

z=\frac{19652}{34 \times 24}

  =17 cm.

The dimension of the cardboard is 34 cm by 34 cm by 17 cm.

The parent function f(x) = log3x has been transformed by reflecting it over the x-axis, stretching it vertically by a factor of
artcher [175]

Answer:

Third option.

Step-by-step explanation:

Some transformations for a function f(x), are:

If f(x)+k, the function is shifted down "k" units.

If f(x)-k, the function is shifted up "k" units.

If bf(x), and b>1, the functio is stretch vertically by a factor of "b".

If  -f(x), the function is reflected over the x-axis.

Therefore, knowing that the parent function f(x) = log_3(x)  was transformated by reflecting it over the x-axis, stretching vertically by a factor of 2 and shifting it down 3 units, we can determine that the following function represents the transformation:

f(x) = -2log_3(x)-3

What is the value of the rational expression x^2-2x-3/4x^2-12 when x = 3?
kotykmax [81]

Answer:

b

Step-by-step explanation:

Given

\frac{x^2-2x-3}{4x^2-12}

Substitute x = 3 into the expression

= \frac{3^2-2(3)-3}{4(3)^2-12}

= \frac{9-6-3}{36-12}

= \frac{0}{24} = 0 → b
