A company is constructing an open-top, square-based, rectangular metal tank that will have a volume of 64 ft3. what dimensions y

Doss [256]

To solve this problem you must apply the proccedure shown below:

1. You must use the formula for calculate the surface area and the volume of the tank:

$1) SA=x^{2} +4xy\\ 2) V=x^{2} y\\ 64=x^{2} y$

2. Solve for $y$ in the second equation and substitute it into the first one.Then, you have:

$y=\frac{64}{x^{2}} \\ SA=x^{2} +4x(\frac{64}{x^{2}})$

3. Now, derivate:

$SA'=2x-256x^{-2} \\ 2x-256x^{-2}=0$

4. When you solve for $x$ , you obtain:

$2x^{3}-256=0\\ x=\sqrt[3]{\frac{256}{2}} \\ x=5.03$

5. Now, you must calculate $y$ :

$y=\frac{64}{(5.03)^{2}} \\ y=2.52$

Therefore, the dimensions are:

The sides of the base of the tank: $5.03 feet$

The height of the tank: $2.52 feet$

(2 to the power -1 ÷ 5 to the power- 1)2 × -5/8 to the power -1

Luba_88 [7]

Answer:

-8

Step-by-step explanation

2 to the power of -1 = 0.5

5 to the power of -1 = 0.2

0.5/0.2 = 2.5

So,

(2.5)2 x -5/8 to the power of -1

-5/8 = -0.625

-0.625 to the power of -1 = -1.6

So,

(2.5)2 x -0.625

5 x -0.625

= -8

Use the rational root theorem to list all possible rational roots for the equation.

Alik [6]

Answer:

The possible rational roots are

$\pm 1, \pm 2,\pm3,\pm6,\pm \frac{1}{3},\pm \frac{2}{3}$

Step-by-step explanation:

We have been given the equation 3x^3+9x-6=0 and we have to list all possible rational roots by rational root theorem.

The factors of constant term are $1, 2, 3,6$

The factors of leading coefficient are $1,3,$

From ration root theorem, the possible roots are the ratio of the factors of the constant term and the factors of the leading coefficient. We include both positive as well as negative, hence we must include plus minus.

$\pm\frac{1,2,3,6}{1,3}\\\\ =\pm 1, \pm 2,\pm3,\pm6,\pm \frac{1}{3},\pm \frac{2}{3}$

This property says that n + 0 = n (for addition) and that 1*n = n (for multiplication). It is the ___ Property.

Artist 52 [7]

The property which states that multiplying a number by 1 does not change the number's value is the identity property. <span>Adding zero to a number does not change the number's value is the zero property, but some people do also call it the identity property of addition. Hope this helped!</span>
