Step-by-step explanation:

Answer: x⁴ + 14x³ + 51x² + 14x - 99 = 0

Step-by-step explanation:

First and foremost, open the brackets by multiplying the variables out.

( x - 1 )( x + 2 ) and  ( x + 8 )( x + 5 ) = 19

Now ( x -  1 )( x + 2 ) = ( x × x + x × 2 -1 × x -1 x 2 )

                                = x² + 2x - x - 2

                                = x² + x - 2 ..................................................... (1)

Again, ( x + 8 )( x + 5 ) = ( x × x + x × 5 + 8 × x + 8 × 5 )

                                    = x² + 5x + 8x + 40

                                    = x² + 13x + 40 ......................................... (2)

Now, Multiply  (1) and (2) and simplify hen equate the result to 19.

( x² + x - 2 )( x² + 13x + 40 )

( x²× x² + x² × 13x + x² × 40 )       =    x⁴ + 13x³ + 40x²

( x × x² + x × 13x + x × 40x )         =        +    x³  +  13x² + 40x

( -2 × x² -2 × 13x -2 × 40    )         =                    -    2x² -  26x - 80

                                                          _______________________

                                                     =     x⁴ + 14x³ +   51x² + 14x - 80

Just carry out the arrangement as follow for easy understanding bearing in mind the powers .

We now equate the result with 19

x⁴ + 14x³ + 51x² + 14x - 80 = 19

x⁴ + 14x³ + 51x² + 14x - 80 - 19 = 0

x⁴ + 14x³ + 51x² + 14 x - 99 = 0

The gravitational potential energy of the vacationers will decrease as they approach the end of the pier.

As the vacationers approach the end of the pier, their gravitational potential energy will decrease.

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field. It depends on the height of the object and the acceleration due to gravity.

In this scenario, as the vacationers walk out on the horizontal pier, their height above the ground remains constant. Since the height does not change, the gravitational potential energy also remains constant.

However, as they approach the end of the pier, their distance from the center of the Earth decreases. As a result, the gravitational potential energy decreases because it is directly proportional to the distance from the center of the Earth.

Using proportions, it is found that:

A proportion is a fraction of a total amount, and the measures in the context of a problem are found using basic arithmetic operations such as multiplication and division.

One application of proportions is for ratio problems, as fractions are built from the ratios to find the equivalent amounts.

Caleb noticed that for every 10 orders of cheese pizza there were 7 orders of pepperoni pizza, 5 orders of sausage pizza and 8 orders of mushroom pizza, hence the fraction of Pepperoni pizzas out of the total is given by:

Pepperoni = 7/(10 + 7 + 5 + 8) = 7/30 of the total.

If 35 pepperoni pizzas were ordered, the total number is found as follows:

7x/30 = 35

7x = 30 x 35

x = 30 x 5

x = 150 pizzas.

2 out of every 25 pizzas were burned, hence the number of burned pizzas is given by:

2/25 x 150 = 2 x 6 = 12 pizzas.

The cheese fraction is given by:

10/30.

Hence, out of 360 pizzas, the number is given by:

10/30 x 360 = 10 x 12 = 120 cheese pizzas

The mushroom fraction is given by:

8/30.

Hence, out of 360 pizzas, the number is given by:

8/30 x 360 = 8 x 12 = 96 mushroom pizzas

The DMM buys the stock from the floor broker who wants to sell; and then immediately sells that stock for $.01 more to the floor broker who wants to buy. This is an example of scalping or trading ahead.

Designated Market Maker (DMM) on the New York Stock Exchange (NYSE), the DMM has certain obligations and responsibilities to maintain fair and orderly markets for the stocks they oversee. They are expected to provide liquidity by facilitating trades and maintaining an orderly market.

However, in the scenario you provided, the DMM takes advantage of the situation by executing a trade with a floor broker who wants to sell ABC stock and immediately selling it to another floor broker who wants to buy at a slightly higher price. By doing so, the DMM profits from the price difference, earning an extra $.01 per share.

This practice goes against the principles of fair and orderly markets, as the DMM is essentially prioritizing their own profit over providing fair execution prices for buyers and sellers. It can be considered unethical and may be subject to regulatory scrutiny or penalties, as it undermines the integrity and fairness of the market.

Answer:

113.1 unit²

Step-by-step explanation:

A cylinder is a shape with two round ends and two parallel lines connecting the round ends.

Height=9  unit, Base=4 unit

The lateral surface area of a cylinder (A) is given by the equation:

\(A=2\pi rh\)

where r is the radius of the cylinder and h is the height of the cylinder.

Given that the base = 4 unit, therefore the diameter (d) = base = 4 unit. Also the height (h) = 9 unit.

Radius (r) = d/2 = 4/2 = 2 unit

Calculating the area of the cylinder is as follows

\(A=2\pi rh\\A=2\pi*2*9\\A=113.1\)

The area of the cylinder is 113.1 unit²

AnswerAnswer:

Step-by-step explanation:

To determine the materials cost for the brooch, we need to know the area of each material used in the brooch. Let's say that the brooch is made up of a 5 cm x 5 cm square of silver, a 2 cm x 2 cm square of copper, and a 3 cm x 1 cm rectangle of stone.

The area of the silver sheet is 5 cm x 5 cm = 25 cm^2, so the cost of the silver is 25 cm^2 x $9.75/cm^2 = $243.75.

The area of the copper sheet is 2 cm x 2 cm = 4 cm^2, so the cost of the copper is 4 cm^2 x $3.25/cm^2 = $13.

The area of the stone is 3 cm x 1 cm = 3 cm^2, so the cost of the stone is 3 cm^2 x $1.75/cm^2 = $5.25.

Therefore, the total materials cost for the brooch is $243.75 + $13 + $5.25 = $262.

Euclid receives 20 shares of common stock as a nontaxable stock dividend.The basis of the common stock remains the same as in scenario a, which is $96.15 per share.

To calculate the per share basis, we divide the original purchase cost by the total number of shares (including the dividend shares).  In scenario b, Euclid receives a nontaxable preferred stock dividend of 20 shares. The preferred stock has a fair market value of $5,000, and the common stock, on which the preferred is distributed, has a fair market value of $75,000.

The tax consequences involve determining the new basis of the preferred stock and the common stock after the dividend. a. To find the per share basis of Euclid's common stock after receiving the stock dividend, we divide the original purchase cost by the total number of shares. The original purchase cost was $50,000 for 500 shares, which means the per share basis was $50,000/500 = $100. After receiving 20 additional shares as a dividend, the total number of shares becomes 500 + 20 = 520.

Therefore, the new per share basis is $50,000/520 = $96.15. b. In this scenario, Euclid receives a preferred stock dividend of 20 shares. The preferred stock has a fair market value of $5,000, and the common stock has a fair market value of $75,000. To determine the new basis of the preferred stock, we consider its fair market value.

Since the preferred stock dividend is nontaxable, its basis is equal to the fair market value, which is $5,000.

Answer:

Ryan's cat will be 15 years old when he is 20.

Step-by-step explanation:

When Ryan is 10, his cat is 5. Therefore if you add ten more years to Ryan's life, the cat will be 15.

The product of the terms   \((d - 9)\)  and  \((2d^{2} + 11d -4)\)  will be \((2d^{3} - 7d^{2} - 103d + 36)\).

We have to find the product of two terms.

First term = (d - 9)

Second term = \((2d^{2} + 11d -4)\)

To find the product of these two terms, we will be using the distributive property. According to the distributive property, when we multiply the sum of two or more addends by a number, it will give the same result as when we multiply each addend individually by the number and then add the products together.

We have to find :  \((d - 9) (2d^2 + 11d -4)\)

Using the distributive property,

\(d * 2d^{2} + d * 11 + d * (-4) - 9 * 2d^2 - 9 * 11d - 9 * (-4)\)

After further multiplication, we get

\(2d^{3} + 11d^2 - 4d - 18d^{2} - 99d + 36\)

Now, combine all the like terms.

\(2d^{3} + 11d^{2} - 18d^{2} - 4d - 99d + 36\)

\(2d^{3} - 7d^{2} - 103d + 36\)

Therefore, the product of d-9 and 2d^2 + 11d -4 is \(2d^{3} - 7d^{2} - 103d + 36\)

We can conclude that the equation has exactly one real root (namely, x = 0) and two complex conjugate roots.

What is the quadratic equation?

The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

I can give an example to demonstrate how to use inspection and Descartes' rule to find a real root of an equation and show that there are no other real roots.

Consider the equation x³ - 3x² + 2x = 0. By inspection, we can see that x = 0 is a real root of the equation since the left-hand side of the equation evaluates to 0 when x = 0.

To use Descartes' rule, we need to count the number of sign changes in the coefficients of the polynomial f(x) = x³ - 3x²  + 2x.

There are two sign changes: from positive to negative in the coefficient of x² and from negative to positive in the constant term.

Therefore, according to Descartes' rule, the equation has either two or zero positive real roots.

Next, we need to count the number of sign changes in the coefficients of f(-x), which is obtained by replacing x with -x in f(x).

We have f(-x) = -x³ - 3x² - 2x, which has one sign change: from negative to positive in the coefficient of x².

Therefore, according to Descartes' rule, the equation has either one or three negative real roots.

Since the total number of positive and negative real roots must add up to the degree of the polynomial (which is 3 in this case),

Hence, we can conclude that the equation has exactly one real root (namely, x = 0) and two complex conjugate roots.

The percentage of Japanese-Americans under 35 in Santa Clara County, CA is approximately 11.3%.

Santa Clara County, CA is home to approximately 27,873 Japanese-Americans. To determine what percentage of this population is under age 35, it is necessary to first calculate the total number of Japanese-Americans under 35. To do this, we can subtract the estimated number of Japanese-Americans over age 35 from the total population of Japanese-Americans. We can then divide this number by the total population of Japanese-Americans to find the percentage of Japanese-Americans under age 35. In Santa Clara County, CA, the estimated number of Japanese-Americans over age 35 is 24,672, and the total population of Japanese-Americans is 27,873. Subtracting 24,672 from 27,873 yields 3,201 Japanese-Americans under age 35. We can then divide 3,201 by 27,873 to get a percentage of 11.3%. Therefore, approximately 11.3% of the Japanese-American population in Santa Clara County, CA is under age 35.

A reasonably simple rule to remember for secants outside the circle or chords inside the circle: the product of the lengths from the point of intersection of the lines to the points of intersection of the circle is the same for each line.

When the external line is tangent to the circle, the two points of intersection of the line with the circle are the same: the point of tangency. Effectively, this means the length is squared.
