Which of the following are roots of the polynomial function?

Answers

Answer 1

The roots f the following polynomial function F(x) = x3 - x2 - 5x - 3 are (A) -1 and (B) 3.

What is a polynomial function?

In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only uses non-negative integer powers or only positive integer exponents of a variable.

For instance, the polynomial 2x+5 has an exponent of 1.

f(x) = anxn + anxn+1 +... + a2x2 + a1x + a0 is the formula for a polynomial. The greatest power of x in an expression is the polynomial's degree.

Polynomials of degrees 0, 1, 2, 3, and 4 are constant (non-zero) polynomials, linear polynomials, quadratics, cubics, and quartics, respectively.

So, there is only one true, positive root, according to Descartes' rule of signs. On the list, 3 is the only real number that is positive.

When dividing x3-x2-5x-3 by (x-3), we may use synthetic division to get the quotient and discover that it is x2+2x+1, which we know as (x+1)2.

As a result, 3 is a root and -1 is a root with multiplicity 2.

A and B are the options that need to be checked.

Therefore, the roots f the following polynomial function F(x) = x3 - x2 - 5x - 3 are (A) -1 and (B) 3.

Who invented the number zero?​

Answers

The concept of zero as a number was likely developed in multiple cultures over thousands of years, so it's difficult to pinpoint a single inventor of zero. However, the use of zero as a placeholder in positional notation systems is attributed to Indian mathematicians, particularly Aryabhata, who introduced the symbol for zero as a dot in the 5th century CE. The concept of zero was then transmitted to the Islamic world, where it was further developed and eventually introduced to Europe during the Middle Ages. Today, the number zero is an essential part of our numerical system and is used in mathematics, science, and technology in various ways.

Aryabhata, the famous Indian mathematician discovered 0.

What is an Integer?

Integers include all whole numbers and negative numbers. This means if we include negative numbers along with whole numbers, we form a set of integers.

The concept of zero was first developed by ancient Indian mathematicians as early as the 5th or 6th century CE. However, the actual symbol for zero (a small circle) was invented by the Indian astronomer and mathematician Brahmagupta in 628 CE.

Determine the value of k such that the points whose coordinates are given lie on the same line. (k, 2), (0, −2), (10, −7)

Answers

The value of k that makes the three points lie on the same line is -8.

To determine the value of k such that the given points lie on the same line, we can use the slope-intercept form of the equation of a line, which is:

y = mx + b

where m is the slope of the line, and b is the y-intercept.

First, we can find the slope of the line passing through the two points (0, -2) and (10, -7):

m = (y2 - y1) / (x2 - x1)

m = (-7 - (-2)) / (10 - 0)

m = -5 / 10

m = -1/2

Now, we can use the slope-intercept form with the point (0, -2) to find the value of b:

-2 = (-1/2)(0) + b

b = -2

So the equation of the line passing through the two points (0, -2) and (10, -7) is:

y = (-1/2)x - 2

To check if the point (k, 2) lies on this line, we can substitute k for x and 2 for y in the equation:

2 = (-1/2)k - 2

4 = (-1/2)k

k = -8

Define perimeter and area

Perimeter and area are two important measurements used in geometry to describe the size and shape of two-dimensional figures.

Perimeter is the measurement of the distance around the outside of a two-dimensional shape. It is the sum of the lengths of all the sides of the shape.

Area is the measurement of the space inside a two-dimensional shape. It is the amount of surface that the shape covers. For example, the area of a rectangle can be calculated by multiplying the length of the rectangle by its width.

Perimeter of the figure=sum of all sides of the figure

Therefore, the derivative of y = 7x⁴ with respect to x is dy/dx = 28x³.

What is differentiation?

Differentiation is a mathematical concept that refers to the process of finding the derivative of a function. The derivative of a function is the rate at which the function changes with respect to its independent variable. In other words, it measures how quickly the output of the function is changing as the input value is changing.

The derivative of a function can be used to determine many properties of the function, such as its slope, maximum and minimum values, and whether it is increasing or decreasing. It is an important tool in calculus and is used in many fields, including physics, engineering, economics, and finance.

The process of differentiation involves applying specific rules to a given function to determine its derivative. The most common method of differentiation is using the power rule, which states that the derivative of a function raised to a power is equal to the product of the power and the function raised to the power minus one. Other rules include the product rule, the quotient rule, and the chain rule, which are used to differentiate more complex functions.

Consider the following square pyramid:
Calculate the Volume of the pyramid.
Volume = _____ m3

Answers

The Volume of the pyramid.

Volume = 288.67

As the volume of the pyramid is the amount of space enclosed inside the pyramid, the formula to find the volume of a square pyramid is given as;

Volume = (1/3) × base area × height.

Where: Base area (B) = s²

Where; s = length of the square pyramid side

And, Height (h) = perpendicular height to the base.

Substituting the given values in the formula we get;

Volume = (1/3) × s² × h

Given, s = 8.5m and h = 12m

Therefore, Volume = (1/3) × 8.5² × 12

= (1/3) × 72.25 × 12

= 288.67 m³

Thus, the volume of the given square pyramid is 288.67 m³, to the nearest hundredth of a cubic meter.

The volume of any pyramid is a measure of the total amount of space enclosed within the pyramid. If you have a pyramid of a specific shape and size, you can calculate its volume by using an appropriate formula. In this case, we have been given the length of the square pyramid side (s) and the perpendicular height (h) of the pyramid to the base. We can use the formula to calculate the volume of the pyramid.

The formula is Volume = (1/3) × base area × height.

For a square pyramid, the base area is the area of the square that forms the base. Since all four sides of the square are of equal length, the area is given as the square of the length of one of the sides. Thus, Base area (B) = s².

a right conical tank with the point oriented down, a height of 14 feet, and a radius of 6 feet has sprung a leak. how fast does the depth of water change when the water is 2 feet high if the cone leaks water at a rate of 13 cubic feet per minute?

Answers

The depth of water changes at a rate of -13/72π feet per minute when the water is 2 feet high.

To begin, we must use the formula for the volume of a cone, which is given as:

V = 1/3πr2hwhere V represents the volume, π represents the constant pi, r represents the radius, and h represents the height.

Substituting the given values into the formula, we get:

V = 1/3π (6 ft)2(14 ft)V = 1/3π (36 ft2) (14 ft)V = 1/3π (504 ft3)V = 168π ft^3

Now, we must determine the rate at which water is leaking. It is given that the cone leaks water at a rate of 13 cubic feet per minute. This implies that the volume of the water reduces by 13 cubic feet every minute. Therefore, the rate of change of the volume of water is -13 cubic feet per minute. Here, the negative sign indicates a decrease in the volume of water.

Now, we must find how fast the depth of water changes when the water is 2 feet high. Let d represent the depth of water. Then, the volume of water is given as:

V = 1/3πr^2d

We know that when d = 2 ft, V = 1/3π(6 ft)2(2 ft)

V = 8π ft^3

Now, we must determine how fast the volume of water is changing with respect to time when d = 2 ft. We differentiate the expression for V with respect to time to get:

dV/dt = (d/dt)[1/3πr2d]

dV/dt = 1/3πr^2(d/dt)[d]

dV/dt = 1/3πr^2(d/dt)[2]

dV/dt = 2/3πr^2

The rate of change of the volume of water with respect to time is given as -13 cubic feet per minute. Therefore, substituting this into the expression above, we get:

-13 = 2/3π(6 ft)2(d/dt)

When we simplify the above equation, we get:

d/dt = -13/72π

Therefore, when the water is 2 feet high, the depth of the water changes at a rate of -13/72π feet per minute.

Write a recursive sequence that represents the sequence defined by the following
explicit formula:

an = -2-4(n − 1)

Answers

The explicit formula for the sequence is:

an = -2-4(n-1)

To write a recursive sequence that represents this sequence, we need to find a formula for the nth term in terms of the (n-1)th term. We can do this by substituting (n-1) for n in the explicit formula:

a(n-1) = -2-4((n-1)-1)
a(n-1) = -2-4(n-2)

We can simplify this expression to get:

a(n-1) = -2-4n+8
a(n-1) = 6-4n

Therefore, the recursive formula for the sequence is:

a1 = -2 (the first term is given)
an = 6-4(n-1) for n > 1

We can check that this recursive formula generates the same sequence as the explicit formula by calculating the first few terms:

a1 = -2
a2 = 6-4(2-1) = 2
a3 = 6-4(3-1) = -2
a4 = 6-4(4-1) = -6
a5 = 6-4(5-1) = -10

We can see that these are the same values as we would get from the explicit formula.

using diagonals from a common vertex, how many triangles could be formed from a 14-gon?

To see why, we can apply the formula for the number of triangles formed by drawing all the diagonals from a single vertex of a polygon, which is (number of sides - 2). For a 14-gon, the formula gives us:

number of triangles = (14 - 2) = 12

However, we need to subtract one from the total because the vertex where the diagonals are drawn from is not included in any of the triangles. Therefore, the number of triangles formed by drawing diagonals from a common vertex of a 14-gon is:

What is Regression Equation?

A regression equation is a mathematical formula that is used to describe the relationship between two or more variables. It is typically used in statistical analysis to model the relationship between a dependent variable and one or more independent variables.In simple linear regression, there is only one independent variable, and the regression equation takes the form of a straight line. In multiple regression, there are two or more independent variables, and the regression equation takes the form of a more complex mathematical function.

Using a calculator, we can input the data points into a regression equation to find the line of best fit. Using the given data, we get the regression equation:

y = -1357.4x + 18003.8

where y represents the retail price of a car and x corresponds to the year, with x = 1 representing 1998.

To predict the average retail price of a car in 2003, we need to substitute x = 6 (since 2003 corresponds to x = 6) into the regression equation:

y = -1357.4(6) + 18003.8

y = -8144.4 + 18003.8

y = 9860.4

So, the predicted average retail price of a car in 2003 is $9860.40.

To determine the year when the car will be worth $814, we need to substitute y = 814 into the regression equation and solve for x:

814 = -1357.4x + 18003.8

Simplifying, we get:

-1357.4x = -17189.8

x = 12.65

Rounding up to the nearest whole number, we get x = 13, which corresponds to the year 2010. Therefore, the car will be worth $814 in the year 2010.

Proportionality is a mathematical relationship between two variables, where one variable is a constant multiple of the other. In other words, two quantities are proportional if they maintain a constant ratio to each other, meaning that as one quantity increases or decreases, the other quantity changes in the same proportion.

We are given that the time it takes to print a batch of newspapers, m, is inversely proportional to the number of printers used, n, and the equation of proportionality is:

m = k/n

where k is a constant of proportionality. We are also given that when k = 100, the equation is satisfied. So we can substitute k = 100 into the equation to get:

m = 100/n

To find the time it will take to print a batch of newspapers if 20 printers are used, we can substitute n = 20 into the equation:

m = 100/20 = 5

consider the sample of 1,400 past negligence cases. suppose you are willing to let the 67% estimate be within .025 (2.5%) of the true proportion. you are willing to assume 95% confidence. is 1,400 an adequate sample size for the estimate of 67%? show why or why not

Answers

We can be reasonably confident that our estimate of 67% is within 2.5% of the true proportion.

What is percentage?

A percentage is a way to describe a part of a whole. such as the fraction  1/4 can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

To determine if a sample size of 1,400 is adequate for estimating a proportion of 67%, we need to calculate the margin of error and compare it to the given tolerance level of 0.025.

We can use the following formula to calculate the margin of error:

E = z x √(p x (1-p)/n)

where:

E is the margin of errorz is the z-score corresponding to the desired confidence level (95% corresponds to a z-score of 1.96)p is the estimated proportion (67% or 0.67 as a decimal)n is the sample size (1,400)

Plugging in the values, we get:

E = 1.96 x √(0.67 x (1-0.67)/1400) ≈ 0.025

So, the margin of error is approximately 0.025. This means that we can expect the true proportion to be within 0.025 of the estimated proportion with 95% confidence.

Since the calculated margin of error is equal to the desired tolerance level, we can conclude that a sample size of 1,400 is adequate for estimating a proportion of 67% with the given level of confidence and tolerance. Therefore, we can be reasonably confident that our estimate of 67% is within 2.5% of the true proportion.
