To find the rational roots of the equation x^(4)-4x^(3)-5x^(2)+16x+4=0, we can use the Rational Roots Test. This test states that any rational root of the equation can be expressed as p/q, where p is a factor of the constant term and q is a factor of the leading coefficient.

In this case, the constant term is 4 and the leading coefficient is 1. The factors of 4 are 1, 2, and 4, and the factors of 1 are 1. Therefore, the possible rational roots are 1, 2, 4, -1, -2, and -4.

We can use synthetic division to test each of these possible roots. If the remainder is 0, then the root is a rational root of the equation. For example, let's test the root 1:

1 | 1 -4 -5 16 4
 |   1 -3 12 28
 ---------------
 | 1 -3 -8 28 32

The remainder is 32, which is not 0, so 1 is not a rational root of the equation.

We can continue to test the other possible roots in the same way until we find the rational roots of the equation. Once we have found the rational roots, we can use them to factor the equation and find the remaining roots.

The minimum total cost for the gas station to store, ship, and purchase 22,032 gallons of diesel for one year is $199,152.87.

The gas station has a steady annual demand for 22,032 gallons of diesel. The cost to store 1 gallon for 1 year is $9, the cost to ship each order of diesel is $34, and the cost to purchase each gallon is $19. To calculate the total cost of storing, shipping, and purchasing the diesel for one year, we can use the following formula:

Total cost = (storage cost per gallon x annual demand) + (shipping cost per order x number of orders) + (purchase cost per gallon x annual demand)

To find the number of orders, we can divide the annual demand by the number of gallons per order. In this case, the number of gallons per order is not given, so we will use the variable "x" to represent it:

Number of orders = 22,032 / x

Plugging this back into the formula, we get:

Total cost = (9 x 22,032) + (34 x 22,032 / x) + (19 x 22,032)

Simplifying, we get:

Total cost = 198,288 + (748,288 / x)

To minimize the total cost, we can take the derivative of the total cost with respect to x and set it equal to zero:

d(Total cost) / dx = -748,288 / x^2 = 0

Solving for x, we get:

x = sqrt(748,288 / 0) = 865.12

Therefore, the gas station should order 865.12 gallons of diesel per order to minimize the total cost. The minimum total cost is:

Total cost = 198,288 + (748,288 / 865.12) = $198,288 + $864.87 = $199,152.87

The minimum total cost for the gas station to store, ship, and purchase 22,032 gallons of diesel for one year is $199,152.87.

Answer:

Step-by-step explanation:

The farmer knows that the 5 camp division is an easier practical solution than the 9 camp division because it does not require dealing with fractions or decimals.

Both fractions and decimals are just two ways to represent numbers. Fractions are written in the form of p/q, where q≠0, while in decimals, the whole number part and fractional part are connected through a decimal point.

To understand why the 5 camp division is an easier practical solution than the 9 camp division, we need to consider the common factors of 8,085 and the numbers 9 and 15.

The prime factorization of 8,085 is:

8,085 = 3 x 3 x 3 x 5 x 5 x 6

The prime factorization of 9 is:

9 = 3 x 3

The prime factorization of 15 is:

15 = 3 x 5

From the prime factorizations, we can see that 9 has a common factor of 3 with 8,085, while 15 has two common factors of 3 and 5 with 8,085. This means that dividing 8,085 into 9 or 15 camps of equal size would require dealing with fractions or decimals, which can be impractical in a farming context.

On the other hand, the prime factorization of 5 is:

5 = 5

Since 5 is a prime number, it does not have any common factors with 8,085. This means that dividing 8,085 into 5 camps of equal size would not require dealing with fractions or decimals. The farmer can simply divide the grazing land into 5 equal parts, each with an area of 1,617 hectares, without needing to perform any division calculations or deal with any fractions or decimals.

Therefore, the farmer knows that the 5 camp division is an easier practical solution than the 9 camp division because it does not require dealing with fractions or decimals.

You will be able to pull out $30,956.52 each month if you want to make withdrawals for 25 years with $300,000 saved for retirement and 10% interest.

To find out how much you will be able to pull out each month if you want to make withdrawals for 25 years with $300,000 saved for retirement and 10% interest, we can use the formula:

Monthly withdrawal = (Starting balance * Interest rate) / (1 - (1 + Interest rate)^(-Number of withdrawals))

In this case, the starting balance is $300,000, the interest rate is 10% or 0.10, and the number of withdrawals is 25 years * 12 months = 300 withdrawals.

Plugging in the numbers, we get:

Monthly withdrawal = ($300,000 * 0.10) / (1 - (1 + 0.10)^(-300))

Monthly withdrawal = $30,000 / (1 - 0.031)

Monthly withdrawal = $30,000 / 0.969

Monthly withdrawal = $30,956.52

Therefore, you will be able to pull out $30,956.52 each month if you want to make withdrawals for 25 years with $300,000 saved for retirement and 10% interest.

The dimensions that would produce the maximum enclosed area are 350ft x 350ft, which will cut off 3 equal size rectangle regions in the yard.

To understand why this is the case, let's consider the problem step-by-step. If Alex wants to cut off three equal size rectangle regions in the yard, he will need to divide the lawn into four equal size rectangles. Let's call the dimensions of two of these rectangles "x" and "y".

To maximize the enclosed area, we want to maximize the area of the lawn that is left over after the three rectangles are cut out. This area can be represented by the equation A = (350-x)(350-y). We know that the total length of the piping is 1400 ft, so the perimeter of the enclosed area (the sum of all four sides) is 1400 ft. This means that 2x + 2y + 1400 = 1400, or 2x + 2y = 0.

Solving for y, we get y = -x + 700. Substituting this equation into the area equation, we get A = (350-x)(350-(-x+700)), which simplifies to A = x(350-x). To find the maximum area, we can take the derivative of this equation with respect to x, set it equal to 0, and solve for x. Doing this, we find that x = 175, which means that y = 525 - x = 350. Therefore, the dimensions that would produce the maximum enclosed area are 350ft x 350ft.

The combination that is produced contains 57.5% corn.. It is calculated by taking the weighted average of the corn content in the two bags, accounting for their respective weights.

(50% x 20 lbs) + (65% x 30 lbs)

= 1750 lbs + 1950 lbs

= 3700 lbs

3700 lbs/50 lbs

= 57.5%

The concentration of corn in the resulting mixture is 57.5%. This is calculated by taking the weighted average of the corn content in the two bags. The first bag, containing 20 pounds of calf starter mix, contains 50% corn. The second bag, containing 30 pounds, contains 65% corn. To calculate the concentration of corn in the mixture, the percentage of corn in each bag is multiplied by its respective weight, and the sums of these two products are then divided by the sum of the two weights. In this case, (50% x 20 lbs) + (65% x 30 lbs) = 1750 lbs + 1950 lbs = 3700 lbs. The resulting concentration of corn in the mixture is 3700 lbs/50 lbs = 57.5%.

To prove that the functions f(x)= (2)/(3)x-8 and g(x)=(3)/(2)x+12 are inverses, we can use composition of functions. We can do this by setting f(g(x)) = x and g(f(x)) = x and showing that they are equivalent.

First, let's look at f(g(x)). We can substitute g(x) into the equation for f(x), so we have: f(g(x)) = (2)/(3)((3)/(2)x+12)-8. Simplifying, we have: f(g(x)) = (4x+48)/6 - 8. Distributing the 4 and rearranging, we have: f(g(x)) = x.

Now let's look at g(f(x)). We can substitute f(x) into the equation for g(x), so we have: g(f(x)) = (3)/(2)((2)/(3)x-8)+12. Simplifying, we have: g(f(x)) = (2x-32)/3 + 12. Distributing the 2 and rearranging, we have: g(f(x)) = x.

The height of the ball launched in the air t seconds after it is launched is given by the equation F(t) = 16t^2 – 220t + 19. We need to find the time t when the ball is falling at 130 feet per second. To do this, we need to find the derivative of the function F(t) with respect to time t, which represents the velocity of the ball at any given time t.

The derivative of F(t) with respect to t is F'(t) = 32t - 220. We can set this equal to 130 to find the time when the ball is falling at 130 feet per second:

The answer of the question based on the probability  that The spinner shows has 4 equal sized sections. Jackson spins the spinner 32 times the answer is 8 times.

A event is any outcome or the set of outcomes of experiment or random process.

An event can be as like as a single outcome or as complex as a combination of the outcomes. For example, flipping a coin and getting heads is an event, as is rolling a die and getting a 6.

The spinner has 4 equal sized sections, then each section has a probability of 1/4 or 25% of being landed on when the spinner is spun.

If Jackson spins the spinner 32 times, we can find the expected number of times each section will be landed on by multiplying the probability of landing on each section by the total number of spins:

Expected number of times to land on each section = (Probability of landing on section) x (Total number of spins)

Expected number of times to land on each section = (1/4) x (32)

Expected number of times to land on each section = 8
