Select the two real roots of the polynomial fun S(r)=r^(5)+5r^(4)-7r^(3)-43r^(2)-8r-48

Answers

Answer 1

The two real roots of the polynomial function S(r) = r^(5) + 5r^(4) - 7r^(3) - 43r^(2) - 8r - 48 are r = -8 and r = 3.

The two real roots of the polynomial function S(r) = r^(5) + 5r^(4) - 7r^(3) - 43r^(2) - 8r - 48 can be found by factoring the polynomial and finding the values of r that make the function equal to zero.

First, we can factor the polynomial using the Rational Root Theorem, which states that if a polynomial has rational roots, they must be of the form 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 -48 and the leading coefficient is 1, so the possible rational roots are ±1, ±2, ±3, ±4, ±6, ±8, ±12, ±16, ±24, and ±48.

We can use synthetic division to test these possible roots and find the ones that make the function equal to zero. After testing the possible roots, we find that the two real roots are r = -8 and r = 3.

When sample size is small and population S.D. is unknown, values on the Z row on the table (or Z values) can't be used (note that Z is normal distribution). The correct option is A, i only.

A small sample is a dataset that contains few observations, making it more difficult to generalize the outcomes to the broader population. When a sample size is small, the sample mean, standard deviation, and other statistical measures may be influenced by chance variations.

Larger samples may be required to represent the overall population precisely. The larger the sample size, the closer the sample mean is likely to be to the true population mean. Additionally, when the sample is large, the sample standard deviation is more likely to be an accurate estimate of the population standard deviation.

A standard normal distribution can be used to find out the probability of obtaining a score in a particular range for a normal distribution. The Z value, or the value on the standard normal distribution, is used to convert any regular distribution to a standard normal distribution, which has a mean of 0 and a standard deviation of 1. However, when the sample size is small and the population standard deviation is unknown, the values on the Z row on the table (or Z values) can't be used.

How to determine the solution of equations' graphs?

Analyzing the intersection of the graphs of a system of linear equations on the coordinate plane will reveal how many solutions there are. The system has a single solution if the graphs meet at a single location. The system cannot be solved if the graphs are parallel and do not intersect. The system has an unlimited number of solutions if the graphs coincide, or overlap.

From the graph we observe that the two lines intersect at the point (1, -2).

The point where the lines intersect is thus the solution of the system of linear equations on the graph.

Given cost and price (demand) functions C(q) = 100q43,800 and p(q) = -29.860, what profit can the company ear by selling 40 items? It can expect to earn sin profit. (Round answer to nearest dollar)

Answers

The company will have a loss of $46,605.60 by selling 40 items.

To find the profit, we need to subtract the cost from the price. The cost function C(q) gives us the cost of producing q items, and the price function p(q) gives us the price of selling q items.

First, let's plug in the value of 40 for q in both functions:

C(40) = 100(40) + 43,800 = 4,000 + 43,800 = 47,800

p(40) = 29.860(40) = 1,194.40

Now we can subtract the cost from the price to find the profit:

Profit = Price - Cost

Profit = 1,194.40 - 47,800

Profit = -46,605.60

Therefore, the company will have a loss of $46,605.60 by selling 40 items.

Note: It is important to make sure that the units for cost and price are the same. In this case, both are in dollars, so we can subtract them directly. If they were in different units, we would need to convert them to the same units before subtracting.

Step-by-step explanation:

A pediatric patient is brought into the ER with an acute allergic reaction. If the patient had been an adult, the prescribed amount of diphenhydramine would be 33 mg, but the patient is only 9 years old. Choose the most appropriate formula given the information you have about the patient to calculate the dose. Round your answer to the nearest tenth of a milligram as necessary.

Answers

The appropriate formula for calculating the dose of diphenhydramine for a pediatric patient is weight (kg) x (age (years)/150) x 33 mg = dose (mg). In this case, the dose would be (9/150) x 33 mg = 2.2 mg, rounded to the nearest tenth of a milligram.

The most appropriate formula to calculate the dose for a pediatric patient is the Clark's rule formula. This formula is used to calculate the dose of a medication for a child based on their weight and the recommended adult dose. The formula is as follows:
Child's dose = (weight of child in pounds / 150) x adult dose
Using this formula, we can calculate the appropriate dose for the 9-year-old patient:
Child's dose = (weight of child in pounds / 150) x 33 mg
Without knowing the weight of the child, we cannot calculate the exact dose. However, once the weight is known, the formula can be used to calculate the appropriate dose and it can be rounded to the nearest tenth of a milligram as necessary.

What is Algebraic Equatiοn?

An algebraic equatiοn is a mathematical statement that uses variables and mathematical οperatiοns such as additiοn, subtractiοn, multiplicatiοn, and divisiοn tο express the equality οf twο algebraic expressiοns.

The gοal οf sοlving an algebraic equatiοn is tο determine the values οf the variables that satisfy the equatiοn.

Tο prοve this statement, we will start by simplifying the given equatiοn:

√x-3a + √x-3b = √x-3c

Subtracting √x-3a frοm bοth sides, we get:

√x-3b = √x-3c - √x-3a

Squaring bοth sides, we get:

(x - 3b) = (x - 3c) + (x - 3a) - 2√(x - 3a)(x - 3c)

Simplifying the right-hand side, we get:

(x - 3b) = 2x - 3(a + b + c) - 2√(x - 3a)(x - 3c)

Mοving all the terms invοlving x tο οne side, we get:

x - 2x + 3(a + b + c) = 2√(x - 3a)(x - 3c) + 3b

Simplifying, we get:

x = (a + b + c) ± 2√(x - 3a)(x - 3c) + 2bc - 2ab - 2ac

Nοw, let's simplify the expressiοn under the square rοοt:

(x - 3a)(x - 3c) = x² - 3ax - 3cx + 9ac

= x² - 3(a + c)x + 9ac

Plugging this back intο the expressiοn fοr x, we get:

x = (a + b + c) ± 2√(x² - 3(a + c)x + 9ac) + 2bc - 2ab - 2ac

Expanding the square rοοt, we get:

x = (a + b + c) ± 2√[(x - (a + c))² - (a - c)²] + 2bc - 2ab - 2ac

= (a + b + c) ± 2√(x - a - c)² - (a - c)² + 2bc - 2ab - 2ac

= (a + b + c) ± 2√(x - a - b - c)² - 4ab - 4bc - 4ac + 2a² + 2b² + 2c²

= (a + b + c) ± 2√a² + b² + c² - ab - bc - ac

why do bones break???

Answers

Answer: Bones break because so much force is applied onto them at a singular moment, more than can be handled. Most commonly from falls where you hit your bone in a specific spot.

Bones can break, also known as a fracture, due to a variety of reasons. Here are some common causes:

Trauma: A sudden force or impact, such as a fall, can cause a bone to break.

Overuse: Repeated stress on a bone over time can cause a stress fracture, which is a small crack in the bone.

Medical Conditions: Certain medical conditions, such as osteoporosis, cancer, or infections, can weaken bones and make them more susceptible to fractures.

Vitamin and Mineral Deficiencies: Insufficient levels of calcium, vitamin D, and other minerals necessary for strong bones can increase the risk of fractures.

The severity of a fracture can vary depending on the force of impact and the strength of the bone. Some fractures may only cause minor pain and swelling, while others may require surgery and a prolonged healing process.

It is important to seek medical attention if you suspect a fracture as prompt diagnosis and treatment can help prevent complications and promote healing. Treatment options for a fracture may include immobilization, casting, surgery, or physical therapy, depending on the severity and location of the break.

Converting feet and inches 4 feet and 11 inches

Answers

Converting 4 feet and 11 inches is equivalent to 59 inches.

The Metric System: What Is It?

The metric system, which bases measurements on the metre for length and kilogramme for mass, was first used in France in 1795. Following the French Revolution, the government tasked scientists with finding a replacement for the nation's dozens of distinct conventional measurement methods. The metre was created by measuring a quadrant of the Earth's circumference that passes through Paris on its way from the North Pole to the Equator. All measurements were made using the new unit, called a metre, which was approximately thirty-nine inches in length.

We know that,

1 foot is equal to 12 inches.

Thus,

4 feet = 4 × 12 inches = 48 inches

Add the 11 inches to get the total:

48 inches + 11 inches = 59 inches

Therefore, 4 feet and 11 inches is equivalent to 59 inches.

The angles in a triangle are 3x – 7, 4x – 1, and 5x + 20.
Is the triangle right-angled?

Answers

Answer:

Yes, the triangle is right-angled since one of the angles is 90°

Step-by-step explanation:

The sum of the three angles of a triangle must add up to 180°

Here the three angles are 3x – 7, 4x – 1, and 5x + 20.

Adding them up gives

3x – 7 + 4x – 1 + 5x + 20 = 180

Grouping like terms:
3x + 4x + 5x - 7 - 1 + 20 = 180

12x + 12 = 180

12x = 180 - 12 = 168

x = 168/12 = 14

Substituting this value of x into each of the expressions:
3x – 7  = 3(14) - 7 = 42 - 7 = 35°

4x – 1 = 4(14) - 1 = 56 - 1 = 55°

5x + 20 = 5(14) + 20 = 70 + 20 = 90°

Since one of the angles is 90° it is indeed a right angled triangle

the ratio of tan is opposite over adjacent from the angle's perspective, and 6 is opposite whereas 8 is adjacent so tan(x)=6/8

the ratio of sin is opposite over hypotenuse from the angle's perspective, where 6 is opposite from it whereas the hypotenuse will always be the side opposite to 90 so it's 10 so sin(x)=6/10

the ratio of cos is adjacent over the hypotenuse from the angle's perspective, where 8 is adjacent to it whereas 10 is the hypotenuse so the ratio will be cos(x)=8/10

Find the inverse equations for f and g.
f(x)=3x+5
g(x)=x^2-6
Explain your process.
Then write about the relationship between the functions and their inverses. Does the domain and range of all functions and inverses follow a pattern?

Answers

To find the inverse equation of f(x) = 3x + 5, we first replace f(x) with y:

y = 3x + 5

Next, we switch x and y and solve for y:

x = 3y + 5

x - 5 = 3y

y = (x - 5)/3

Therefore, the inverse of f(x) is f^-1(x) = (x - 5)/3.

To find the inverse equation of g(x) = x^2 - 6, we replace g(x) with y:

y = x^2 - 6

Next, we switch x and y and solve for y:

x = y^2 - 6

x + 6 = y^2

y = ±sqrt(x + 6)

Since we want a function, we take the positive square root:

y = sqrt(x + 6)

Therefore, the inverse of g(x) is g^-1(x) = sqrt(x + 6).

The relationship between a function and its inverse is such that if (a,b) is a point on the graph of f, then (b,a) is a point on the graph of f^-1. In other words, the roles of x and y are reversed in the inverse function. The domain of the function becomes the range of the inverse, and the range of the function becomes the domain of the inverse.

In general, not all functions have inverses. For a function to have an inverse, it must be one-to-one (i.e., each x-value in the domain maps to a unique y-value in the range). If a function is not one-to-one, then it may be possible to restrict the domain to a smaller interval so that the restricted function does have an inverse. When a function has an inverse, the domain and range of the inverse follow a pattern as stated above.

The monthly salary of Mr. Jha is Rs. 16,500. He spend his income in every month in the following ways:
Food:- 20%, House:- 25%, Fuel:- 10%, Miscellaneous:- 15%
(i) Find his monthly expenditure on each item.
(ii) How much does he save every month?

Answers

Answer:
(i) Rs. 3,300, Rs. 4,125, Rs. 1,650, and Rs. 2,475

(ii) 4,950

Step-by-step explanation:

i) To find Mr. Jha's monthly expenditure on each item, we can use the given percentages to calculate the amount he spends on each category:

Food expenditure = 20% of Rs. 16,500 = 0.20 x 16,500 = Rs. 3,300

House expenditure = 25% of Rs. 16,500 = 0.25 x 16,500 = Rs. 4,125

Fuel expenditure = 10% of Rs. 16,500 = 0.10 x 16,500 = Rs. 1,650

Miscellaneous expenditure = 15% of Rs. 16,500 = 0.15 x 16,500 = Rs. 2,475

Therefore, Mr. Jha's monthly expenditure on food, house, fuel, and miscellaneous items is Rs. 3,300, Rs. 4,125, Rs. 1,650, and Rs. 2,475 respectively.

(ii) To calculate how much Mr. Jha saves every month, we can subtract his total expenditure from his monthly income:

Total expenditure = Rs. 3,300 + Rs. 4,125 + Rs. 1,650 + Rs. 2,475 = Rs. 11,550

Savings = Monthly income - Total expenditure = Rs. 16,500 - Rs. 11,550 = Rs. 4,950

Therefore, Mr. Jha saves Rs. 4,950 every month.

What's the vertex form of the equation modeling g?

Answers

The vertex form of the equation for function g is g(x) = a(x + 1)² - 38, where a is the same as in function f.

What is the quadratic function?

A quadratic function is one of the forms f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero.

The vertex form of the equation of a quadratic function is given by:

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex. To find the vertex form of the equation for function g, we need to determine the vertex of function f and then adjust it to 2 units below and 3 units to the left.

To find the vertex of function f, we can use the formula:

h = -b / 2a

where a and b are the coefficients of the quadratic term and the linear term, respectively.

For function f(x) = x² - 4x - 32, we have a = 1 and b = -4, so the vertex has an x-coordinate of:

h = -b / 2a = -(-4) / 2(1) = 2

To find the y-coordinate of the vertex, we can substitute this value of h into the function:

f(2) = 2² - 4(2) - 32 = -36

So the vertex of function f is (2, -36).

To adjust the vertex of the function f 2 units below and 3 units to the left, we need to subtract 2 from the y-coordinate and add 3 to the x-coordinate. Therefore, the vertex of function g is:

(h, k) = (2 - 3, -36 - 2) = (-1, -38)

Therefore, the vertex form of the equation for function g is g(x) = a(x + 1)² - 38, where a is the same as in function f.

A population consists of five members 2,3,6,8,1). consider all possible samples of size two which can be doamn with replacement from this positioning population. Find, i) the mean and the standard deviation of the population,
ii) The mean and standard error of sample mean (x) from the sampling distribution of x.

Answers

A population consists of five members 2,3,6,8,1). consider all possible samples of size two which can be doamn with replacement from this positioning population.  The mean is  4 and standard deviation of the population is 1.67. The mean and standard error of sample mean (x) from the sampling distribution of x is 4 and 1.18 respectively

i) The mean and standard deviation of the population:

Mean = (2+3+6+8+1)/5 = 20/5 = 4

Standard deviation = √[(2-4)²+(3-4)²+(6-4)²+(8-4)²+(1-4)²]/5 = √14/5 = 1.67


ii) The mean and standard error of sample mean (x) from the sampling distribution of x:

Mean of sample mean = Mean of population = 4

Standard error of sample mean = Standard deviation of population/√n = 1.67/√2 = 1.18


The mean of a population is calculated by adding up all the values and dividing by the number of values in the population. The standard deviation of a population is calculated by finding the difference between each value and the mean, squaring those differences, adding them up, and then dividing by the number of values in the population.

The mean of the sample mean is the same as the mean of the population, and the standard error of the sample mean is the standard deviation of the population divided by the square root of the sample size.

A deli uses rye bread for (4)/(5) of the sandwiches ordered. Of those, (1)/(3) are ham sandwiches. What fraction of all the sandwiches that the deli makes is a ham sandwich on rye bread?

Answers

The fraction of all the sandwiches that are ham sandwiches on rye bread is 4⁄15.

To find the fraction of all the sandwiches that are ham sandwiches on rye bread, we need to multiply the fraction of sandwiches that use rye bread by the fraction of those that are ham sandwiches.

Here's how we can do that:

1. Start with the fraction of sandwiches that use rye bread: (4)/(5)
2. Multiply that by the fraction of those that are ham sandwiches: (1)/(3)
3. Multiply the numerators together: 4 x 1 = 4
4. Multiply the denominators together: 5 x 3 = 15
5. Put the new numerator and denominator together to get the fraction: (4)/(15)

So, the fraction of all the sandwiches that are ham sandwiches on rye bread is (4)/(15).

Use a double angle, half angle, or power reducing formula to rewrite cos^4(x)sin^2(x) without exponents.

Answers

The expression [tex]cos^4(x)sin^2(x)[/tex] can be rewritten without exponents as [tex]cos^2(x) - (\frac{1}{2} )cos^4(x)[/tex].

The double angle, half angle, or power-reducing formula can be used to rewrite [tex]cos^4(x)sin^2(x)[/tex] without exponents. One of the approaches to rewriting is by applying the power-reducing formula. The power-reducing formula is a trigonometric identity that is used to reduce powers of sine and cosine functions.

To rewrite [tex]cos^4(x)sin^2(x)[/tex] without exponents, you can use the power reducing formula. This formula states that:
[tex]cos^2(x)*sin^2(x) = (\frac{1}{2} )(1-cos(2x))[/tex]

We can use this formula to break down [tex]cos^4(x)sin^2(x)[/tex] as follows:
[tex]cos^4(x)sin^2(x) = cos^2(x)sin^2(x)cos^2(x) = (\frac{1}{2} )(1-cos(2x))cos^2(x)[/tex]

Next, we can use the double angle formula, which states that:
[tex]cos(2x) = 2cos^2(x) - 1[/tex]

Plugging this into our equation, we get:
[tex]cos^4(x)sin^2(x) = (\frac{1}{2} )(1-2cos^2(x)+1)cos^2(x) = cos^2(x) - (\frac{1}{2} )cos^4(x)[/tex]


Therefore, the expression [tex]cos^4(x)sin^2(x)[/tex] can be rewritten without exponents as [tex]cos^2(x) - (\frac{1}{2} )cos^4(x)[/tex].
