The volume of a sphere is 3052.08 units cubed what is its diameter?

Answer:

3456

Step-by-step explanation:

the given equation is: [tex](3^{2} 8) (4^{2} 3)[/tex]

= (9 × 8) (16 × 3)

= (72) (48)

= 3456

[tex]\bf \begin{cases} R(x)=58x-0.4x^2\\ C(x)=2x+14 \end{cases} \\\\[-0.35em] ~\dotfill\\\\ P(x)\implies \stackrel{revenue}{R(x)}-\stackrel{costs}{C(x)}\implies (58x-0.4x^2)-(2x+14) \\\\\\ (58x-0.4x^2)-2x-14\implies 58x-0.4x^2-2x-14 \\\\\\ 56x-0.4x^2-14\implies \boxed{-0.4x^2+56x-14} \\\\[-0.35em] ~\dotfill[/tex]

[tex]\bf R(80)\implies 58(80)-0.4(80)^2\implies R(80)=4640-2560\implies \boxed{R(80)=2080} \\\\[-0.35em] ~\dotfill\\\\ C(80)=2(80)+14\implies C(80)=160+14\implies \boxed{C(80)=174} \\\\[-0.35em] ~\dotfill\\\\ P(80)=-0.4(80)^2+56(80)-14 \\\\\\ P(80)=-2560+4480-14\implies \boxed{P(80)=1906}[/tex]

The profit function P(x) is 56x - 0.4x² - 14. When we plug x=80 into the equations, we find that R(80) = 3680, C(80) = 174, and P(80) = 3506.

To solve the student's question, firstly we use the provided data. The profit function P(x) can be expressed as the difference between the revenue function R(x) and the cost function C(x).

To find P(x), we subtract the equation for C(x) from the equation for R(x). So, P(x) = R(x) - C(x) = (58x - 0.4x²) - (2x + 14) = 56x - 0.4x² - 14.

To answer the second part of the question, we substitute x=80 into the equations for R, C, and P.
Therefore R(80) = 58×80 - 0.4×80² = 3680, C(80) = 2×80 + 14 = 174, and P(80) = 56×80 - 0.4×80² - 14 = 3506.

Final answer:

The function f(x) = 4(2)^(-x) - 3 approaches -3 as x approaches infinity and decreases without bound as x approaches negative infinity, with a horizontal asymptote at y = -3.

Explanation:

The end behavior of a function describes what happens to the function's values as x approaches infinity or negative infinity. For the function f(x) = 4(2)^(-x) - 3, as x approaches infinity, the term 2^(-x) approaches zero, because any non-zero base raised to the power of negative infinity is zero. Thus, the function approaches -3. Conversely, as x approaches negative infinity, the term 2^(-x) grows exponentially, and the function's values decrease without bound, heading towards negative infinity. However, since f(x) involves a negative exponential function, the graph ultimately will approach the horizontal asymptote y = -3.

Answer:

y = 3x² - 6x - 72

Step-by-step explanation:

Since the roots are x = - 4 and x = 6 then the factors are

(x + 4) and (x - 6) and the quadratic function is

y = a(x + 4)(x - 6) ← a is a multiplier, in this case 3, so

y = 3(x + 4)(x - 6) ← expand factors and distribute by 3

y = 3(x² - 2x - 24)

y = 3x² - 6x - 72

3x²-6x-72. The quadratic equation whose  roots are -4 and 6 with a leading coefficient of 3 is 3x²-6x-72.

The solutions of a quadratic equation are x = -4 and x = 6 with a leading coefficient of 3. The solutions are two real numbers which means that (x + 4) and (x - 6) are the factors of our unknown quadratic equation and the leading coefficient is 3.

Answer:

2.5

Step-by-step explanation:

lower quartile.

3, 4, 5, 5, 6, 6, 7, 7, 8

median = 6

lower quartile 1/4th position

(4+5)/2 = 4.5

Upper quartile 3/4th position

(7+7)/2 = 7

Interquartile range = upper quartile - lower quartile

                                = 7 - 4.5

                                 = 2.5

Answer:

Interquartile range = Q3 - Q1 = 7 - 4.5 = 2.5

Step-by-step explanation:

Before we calculate interquartile range, you should understand that:

Interquartile range is the range between Q3 and Q1 of a dataset i.e Q3 - Q1

Where,

Q1 is the middle value in the first half of the data set and

Q3 is the middle value in the second half of the data set.

So to calculate the interquartile range we find the Q3 and Q1

5, 6, 7, 3, 4, 5, 6, 8, 7

So in the data set to find Q1 and Q3, we rearrange the dataset and divide it into First half and second half.

3, 4, 5, 5, 6, 6, 7, 7, 8

First half = 3, 4, 5, 5

Second half = 6, 7, 7, 8

So

Q1 = (4+5)/2 = 4.5

Q3 = (7+7)/2 = 7

Interquartile range = Q3 - Q1 = 7 - 4.5 = 2.5

Given that the volume of a rectangular prism is length x width x height, this problem can be solved by setting up the equation 2w * w * 8 = 400, where w is the width and 2w is the length. Solving this equation, we find that the width is 5 feet and the length is 10 feet.

In mathematics, the volume of a rectangular prism is given by the formula length x width x height. We are given that the volume of the storage container is 400 cubic feet, its height is 8 feet, and the length is twice the width. Let us denote the width as w, then the length is 2w.

From the given volume formula, we have:

Length x Width x Height = Volume

Substituting the values, we get:

2w * w * 8 = 400

Solving this equation, we find:

w^2 = 25

Taking the square root of both sides, we get:

w = 5

Substituting w=5 into 2w, we find the length:

Length = 2*5 = 10

So the width of the container is 5 feet and the length is 10 feet.

Answer:

C

Step-by-step explanation:

Firstly, we know that the function must be negative due to its shape. This means that the answer cannot be B

Next we can use the equation [tex]x=\frac{-b}{2a}[/tex] that is used in order to find the vertex of the parabola.

A)

[tex]f(x)=-x^2+6x+7\\a=-1,b=6,c=7\\\\x=\frac{-6}{-2} \\x=3[/tex]

As the vertex is at x=3 on the graph, this one could be a contender.

C)

[tex]f(x)=-x^2+6x-7\\a=-1,b=6, c=-7\\\\x=\frac{-6}{-2} \\\\x=3[/tex]

This also could be the equation

D)

[tex]f(x)=-x^2-6x-7\\\\a=-1, b=-6, c=-7\\\\x=\frac{6}{-2} \\\\x=-3[/tex]

This rules option D out.

For this last step, we can look at where the zeroes would be for each equation. (These values are irrational, so we cannot look at specific number)

A)

[tex]f(x)=-(x^2-6x-7)[/tex]

As this equation has a negative value for c, this means that one zero must be positive and the other must be negative.

This means that option A can be ruled out

C)

[tex]f(x)=-(x^2-6x+7)[/tex]

As this equation has a positive value for c, this means that both of the zeroes must be positive. This means that it is the only one that fits all of the criteria.

Answer:

30 mph

Step-by-step explanation:

The average speed = Total distance / Total Time

Distance at 45 m/hr.

t = 20 minutes = 20/60 = 1/3 hour.

r = rate = 45 miles / hour

d = r * t

d = 45 * 1/3 = 15 miles.

Average Speed going home.

t =  30 minutes

t = 30 min / 60 min // hour = 1/2 hours

r = 15 miles / 1/2 = 15 * 2 =  30 miles / hr.

Answer: it will take 1.25 hours

Step-by-step explanation:

It

It will take the teacher 1.25 hours to print 6,000 pages.

To calculate how long it will take to print 6,000 pages with a copy machine that can print 80 sheets per minute, we need to divide the total number of pages by the rate of printing per minute to find out the time in minutes, and then convert that time into hours if necessary.

Step 1: Divide the total number of pages by the printing speed to find the time in minutes.

Total pages: 6,000

Printing speed: 80 pages/minute

Time calculation: 6,000 pages divided by 80 pages/minute = 75 minutes

Step 2: Convert minutes into hours by dividing by 60 since there are 60 minutes in an hour.

Conversion to hours: 75 minutes divided by 60 minutes/hour = 1.25 hours

Therefore, it will take the teacher 1.25 hours to print 6,000 pages.

Answer:

The sum of the angles that do not measure 22 degrees is equal to 316°

Step-by-step explanation:

The question in English is

A rhombus has a 22-degree angle. How much is the sum of its angles that do not measure 22 degrees worth?

we know that

The opposite internal angles of a rhombus are equal and the adjacent internal angles are supplementary

so

Let

x -----> the measure of an adjacent angle to 22 degrees in the rhombus

x+22°=180°

x=180°-22°=158°

therefore

The sum of the angles that do not measure 22 degrees is equal to

158°+158°=316°

Answer:

The linear inequality is [tex]y > \cfrac 23 x+3[/tex], which is the third option.

Step-by-step explanation:

In order to determine the inequality, we need to first identify the line equation associated to it, to do that we can identify a couple of points and get the slope then the line equation.

Identifying points and finding slope.

From the segmented line we can tell that it crosses the points (0,3) and (3, 5), thus we can find the slope using

[tex]m = \cfrac{y_2-y_1}{x_2-x_1}[/tex]

Replacing the points we get

[tex]m= \cfrac{5-3}{3-0}[/tex]

[tex]m = \cfrac 23[/tex]

Writing the line equation.

Now that we have the slope m, and a point (0,3) we can find the line equation using,

[tex]y-y_1 = m(x-x_1)[/tex]

Replacing the point and slope we get

[tex]y-3 = \cfrac 23 (x-0)[/tex]

Simplifying and solving for y we get

[tex]y = \cfrac 23 x+3[/tex]

Writing the inequality.

Notice that the associated line is a segmented line, so the linear inequality does not contain it that is why we only need to use greater than or less symbols.

Then we can tell that the shaded area is above the segmented line so we can conclude that the linear inequality is

[tex]y > \cfrac 23 x+3[/tex],

And that is the third option.
