Answer:

(140, 30,072) and (380, 19608).

Step-by-step explanation:

We are given that the revenue function for selling the kitchen table given its price is:

[tex]R(x)=-0.68x^2+310x[/tex]

And the cost function is:

[tex]C(x)=-43.6x+36176[/tex]

At the breakeven point, the revenue equals the cost. Therefore:

[tex]R(x)=C(x)[/tex]

Substitute:

[tex]-0.68x^2+310x=-43.6x+36176[/tex]

We can solve for x.

Adding 0.68x² to both sides and subtracting 310x from both sides yields:

[tex]0.68x^2-353.6x+36176=0[/tex]

We can use the quadratic formula:

[tex]\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

In this case, a = 0.68, b = -353.6, and c = 36176. Substitute:

[tex]\displaystyle x=\frac{-(-353.6)\pm\sqrt{(-353.6)^2-4(0.68)(36176)}}{2(0.68)}[/tex]

Simplify:

[tex]\displaystyle x=\frac{353.6\pm\sqrt{26684.24}}{1.36}[/tex]

So, our two solutions are:

[tex]\displaystyle x=\frac{353.6+\sqrt{26684.24}}{1.36}\text{ or } x=\frac{353.6-\sqrt{26684.24}}{1.36}[/tex]

Use a calculator:

[tex]x\approx 380\text{ or } x\approx 140[/tex]

Our answers are:

(140, 30,072) and (380, 19608).

Answer:

[tex]\frac{x}{9}[/tex]

Step-by-step explanation:

Given

[tex]\frac{x^2 - 9}{9x + 27} \div \frac{x - 3}{x}[/tex]

Required

Solve

[tex]\frac{x^2 - 9}{9x + 27} \div \frac{x - 3}{x}[/tex]

Change the division to multiplication

[tex]\frac{x^2 - 9}{9x + 27} * \frac{x}{x - 3}[/tex]

Apply difference of 2 squares

[tex]\frac{(x - 3)(x+3)}{9x + 27} * \frac{x}{x - 3}[/tex]

Cancel out x - 3

[tex]\frac{x+3}{9x + 27} * \frac{x}{1}[/tex]

Factorize 9x + 27

[tex]\frac{x+3}{9(x + 3)} * \frac{x}{1}[/tex]

Cancel out x + 3

[tex]\frac{1}{9} * \frac{x}{1}[/tex]

Finally, this gives:

[tex]\frac{x}{9}[/tex]

Answer:

The cost of required steel is [tex]169.56 *27 = 4578.12[/tex] dollars

Step-by-step explanation:

The surface area of cylinder will be equivalent to the area of the steel sheet.

Surface area of cylinder [tex]= 2\pi rh+2\pi r^2[/tex]

Substituting the given values we get

Surface area of cylinder

[tex]= 2*3.14*3*6 + 2*3.14 *3^2\\= 169.56[/tex]square meter

Cost of 1 square meter of steel is  $27

Then, the cost of required steel is

[tex]169.56 *27 = 4578.12[/tex] dollars

Answer:

Step-by-step explanation:

Let the angle of elevation be \thetaθ

\begin{gathered} \therefore \tan \: \theta = \frac{height \: of \: mast}{height \: of \: shadow} \\ \\ \therefore \tan \: \theta = \frac{44}{14} \\ \\ \therefore \tan \: \theta = 3.14285714 \\ \\ \therefore \: \theta = {\tan}^{ - 1} (3.14285714) \\ \therefore \: \theta = 72.349875765 \degree \\ \\ \huge \red{ \boxed{\therefore \:\theta = 72.35 \degree}}\end{gathered}

∴tanθ=

∴tanθ=

∴tanθ=3.14285714

∴θ=tan

(3.14285714)

∴θ=72.349875765°

∴θ=72.35°

Hence, angle of elevation of the sun is 72.35°.

Answer:

4.Answer. -2 or 1. By using cross multiplication..Like this.

The number of yards fencing the homeowner need to surround the entire lot is 78.5 yards. Therefore, the option D is the correct answer.

The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its centre. A meridian is any great circle passing through a point designated a pole.

Given that, a house is located at the center of a circular lot, exactly 25 yards from the edge of the lot.

Here, d = 25 yards

Radius = 25/2 = 12.5 yards

We know that, the circumference of a circle = 2πr

= 2×3.14×12.5

= 78.5 yards

Therefore, the option D is the correct answer.

Step-by-step explanation:

pretty self explanatory

Answer:

As it says he is incorrect.

Step-by-step explanation:

To start, if you were to multiply something such as 5*1, then you would get the same number. Another example would be 8*0. Anything multiplied by 0 IS zero. He does give some valid answers, but there are also ones with smaller numbers. That is why Jackson is incorrect.

Complete question is;

The attached chart shows the (approximate) total number of subprime home mortgages in a state in November 2008, broken down into four categories.

What is the probability that a randomly selected subprime mortgage in the state during November 2008 was not current? (Round your answer to two decimal places.)

Answer:

Probability that the one randomly selected was not current = 0.36

Step-by-step explanation:

From the attached image, we can see that the four mortgage categories are mutually exclusive. This means that none of the 4 status depends on any other.

From the image attached;

Total number of subprime mortgages = 196,280

Number of current mortgages = 126,330

Thus;

Probability of a randomly selected subprime mortgage being current = 126330/196280 = 0.64

Then;

Probability that the one randomly selected was not current = 1 - 0.64

Probability that the one randomly selected was not current = 0.36

Step-by-step explanation:

Given:

Slanted Hight of cone = 15 unit

Radius of cone = 8 units

Find:

Total surface area of cone

Computation:

Total surface area of cone = πr[l + r]

Total surface area of cone = (22/7)(8)[15 + 8]

Total surface area of cone = (22/7)(8)[23]

Total surface area of cone = (22/7)(184)

Total surface area of cone = 4,048 / 7

Total surface area of cone = 578.28 unit²
