a rectangular container with a square base, an open top, and a volume of 4,000 cm3 is to be made. what is the minimum surface area for the container? enter only the minimum surface area, and do not include units in your answer.

Answers

A rectangular container with a square base, an open top, and a volume of 4,000 cm³. The minimum surface for the container is 1,200 cm².

The result is obtained by using the derivative.

Determine the minimum surface area

These are the specified parameters:

Volume container is 4,000 cm³.

Let side of square base = a, and height of the container = h, so:

Volume = a × a × h

4,000 = a² h

       h = [tex]\displaystyle \frac{4000}{a^2}[/tex]     ... (1)

Surface area with a square base, an open top is area of a square + 4 times the vertical side.

Surface area (A) = a² + 4ah

Substitute the value of h = [tex]\displaystyle \frac{4000}{a^2}[/tex] into surface area.

A = a² + 4ah

A = a² + 4a ([tex]\displaystyle \frac{4000}{a^2}[/tex])

A = a² + [tex]\displaystyle \frac{16000}{a}[/tex]

So that the surface area is minimal, when the derivative and equate to 0.

A = a² + 16000 a⁻¹

A' = 0

2 a²⁻¹ + (-1) 16000 a⁻¹⁻¹

2a - 16000 a⁻²  = 0

2a - [tex]\displaystyle \frac{16000}{a^2}[/tex] = 0

2a = [tex]\displaystyle \frac{16000}{a^2}[/tex]

2a³ = 16000

 a³ = [tex]\displaystyle \frac{16000}{2}[/tex]

 a³ = 8000

 a = ∛8000

 a = 20

Surface area with a square base, an open top.

Substitute the value of a = 20

A = a² + [tex]\displaystyle \frac{16000}{a}[/tex]

A = 20² + [tex]\displaystyle \frac{16000}{20}[/tex]

A = 400 + 800

A = 1200

The minimum surface for the container is 1,200 cm².

The new coordinate after the given composite translation (x,y) → (x-5,y+5) will be (x+3,y+12).

What is the transformation of a graph?

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

Reflection is a mirror image of a graph about any axis.

If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).

As per the given translation rule,

(x,y) → (x+8,y+7)

The next translation is (x,y) → (x-5,y+5)

The resultant translation will be,

(x,y) → (x+8,y+7) to (x+8-5,y+7+5)

⇒ (x+3,y+12)

Hence "The new coordinate after the given composite translation (x,y) → (x-5,y+5) will be (x+3,y+12)".

Samantha is a salesperson who sells computers at an electronics store. She makes a base pay amount each day and then is paid a commission for every computer sale she makes. The equation P=6.25x+75 represents Samantha's total pay on a day on which she sells x computers. What is the slope of the equation and what is its interpretation in the context of the problem?

Answers

The slope is 6.25, it means that her day pay increases by $6.25 for each computer sold

What is the slope of the equation?

A general linear equation in the point-slope form is written as:

y = a*x + b

Where y and x are the two variables, a is the slope, and b is the y-intercept.

In this case, the linear equation is:

P(x) = 6.25*x + 75

We know that P(x) represents her pay, and x represents the amount of computers she sold.

Here we can see that the slope is 6.25, it means says how much her pay increases per computer sold.

modeling real life an animal shelter director is planning to build a rectangular playpen. the playpen must have a perimeter of 150 feet and an area of at least 1000 square feet. describe the possible lengths of the playpen. the length must be at least feet and at most feet.

Answers

For the given rectangular playpen, the perimeter of rectangular playpen is 150 feet and its area is at least 1000 square feet. then the length of the rectangular playpen is equal to at least 17.35 feet and at most 57.66 feet.

As given in the question,

For the given rectangular playpen,

Perimeter of rectangular playpen is equal to 150 feet .

Area of the rectangular playpen is equal to at least 1,000 squared feet .

Area = length × width

Let x be the length of the rectangular playpen .

Then its width is equal to 1000 / x.

Substitute the value of length and width in perimeter we get,

Perimeter of rectangular playpen = 2 ( length + width )

⇒ 150 = 2 [ x + (1,000/x)]

⇒ 150 / 2 = ( x² + 1,000 ) / x

⇒ x² + 1000 = 75x

⇒ x² -75x + 1,000 =0

Simplify quadratic equation using discriminant we get,

x = [ -( -75) ± √(-75)² - 4(1) (1,000) ] / 2(1)

⇒ x = (  75 ± √5625 - 4000) /2

⇒ x = (75 ± 40.31) / 2

⇒ x = 57.66 or 17.35

Therefore, for the given rectangular playpen, the perimeter of rectangular playpen is 150 feet and its area is at least 1000 square feet. then the length of the rectangular playpen is equal to at least 17.35 feet and at most 57.66 feet.

Answers

Answer:

The amount of cholesterol in 11 ounces of lobster is 220 mg

Step-by-step explanation:

The amount of cholesterol in 11 ounces of lobster can be calculated as follows

The first step is to convert all units of measure from ounce to mg

1 gram = 0.0352 ounce

Divide both sides by 0.0352 to get the value of 1 ounce

[tex]\frac{1}{0.0352}[/tex] gram = [tex]\frac{0.0352}{0.0352}[/tex] ounce

28.35 gram = 1 ounce

Since 1 gram equals 1000 milligrams, then multiply the left side by 1000 and change the unit of measure to milligram

28.35 [tex]\times[/tex] 1000 mg = 1 ounce

28350 mg = 1 ounce

Convert 3.6 ounces to milligrams

3.6 ounces = 3.6 [tex]\times[/tex] 28350 mg

3.6 ounces = 102060 mg

Convert 11 ounces to milligrams

11 ounces = 11 [tex]\times[/tex] 28350 mg

11 ounces = 311850 mg

Since there are 72 mg of cholesterol in a 3.6 ounces serving of lobster, then the ratio equation to follow is

[tex]\frac{72}{102060}=\frac{x}{311850}[/tex]

Where x is the amount of cholesterol in 11 ounces of lobster

Multiply both sides by 311850 to isolate x

[tex]\frac{72}{102060}\times 311850=\frac{x}{311850}\times 311850[/tex]

[tex]\frac{22453200}{102060} =x[/tex]

Simplify the left side of the equation

220 = x

Since the value of x is 220, then the amount of cholesterol in  11 ounces of lobster is 220 mg

Answers

Annual nominal rate compounded monthly has the account earned is 0.84% .

In the question ,

it is given that ,

An employee opened a credit union account ,

amount deposited each month (PMT) = $90

number of period (n) = 2 years = 24 months

Future value after 2 years (FV) = $2177.48

let the rate of interest  compounded monthly has the account earned be "r"

we know that the future value formula is

Future Value = PMT× [tex](\frac{(1+\frac{r}{12})^{n} -1 }{\frac{r}{12} } )[/tex]

Substituting the value of n = 24 , PMT = 90 and FV = 2177.48 in the Future Value Formula ,

we get ,

2177.48 = 90 × [tex](\frac{(1+\frac{r}{12})^{24} -1 }{\frac{r}{12} } )[/tex]

[tex](\frac{(1+\frac{r}{12})^{24} -1 }{\frac{r}{12} } )[/tex] = 2177.48/90

( 1 + r/12 )²⁴ -1 = (r/12) × 24.194

What are consecutive integers?

Whole numbers that follow each other without gaps are known as consecutive integers.

For example, the numbers 15, 16, and 17 are all consecutive integers.

If 'n' is an integer, then the following consecutive integers begin at n, n+1, n+2, n+3, and so on.

Let x be the 1st of the four consecutive integers.

the other three consecutive integers could be

(x + 1) , (x + 2), and (x + 3).

By using the given conditions, we get

From the question,

(x + 1) = (5 * (x + 2)) - (x + 3)

Expand, and subtract like terms:

x + 1 = 5x + 10 - x - 3.

x + 1 = 4x + 7.

Answers

The measure of one of its angle is 150°

A Polygon is a two-dimensional closed figure made up of line segments (not curves). Polygon is a combination of two words, poly (which means many) and gon (which means shape) (means sides). To create a closed figure, at least three line segments must be connected end to end.

Given that

[Where n = number of sides]

(12−2)⋅180

(10)⋅180

=1800

So a 12-sided polygon has 1800 degrees. To calculate the measure of one angle, divide the total number of degrees (1800) by the number of sides, n.
