[tex]\pi[/tex]

Answers

Answer 1

Answer:

The volume of each cylinder is given by the formula: V = πr^2h, where r is the base radius and h is the height of the cylinder.

When 25 cylinders are put into the half-filled container, the water level rises to the top of the container, which means that the total volume of the 25 cylinders is equal to the volume of the container. Let's assume the volume of the container is V_container.

So, 25 * πr^2 * h = V_container

Dividing both sides by 25πh gives: r^2 = V_container / (25πh)

Taking the square root of both sides gives: r = √(V_container / (25πh))

Since h = 10 cm, we can substitute this value in the formula above: r = √(V_container / (25π * 10))

Since r is the base radius of the cylinder, it must be positive. So, the final equation becomes:

r = √(V_container / (25π * 10)) cm = 5√(5/π) cm. shown

By using 3.14 for the value of π, we can calculate the value of r:

r = 5√(5/π) = 5√(5/3.14) = 5 * √(5/3.14)

= 5 * √(1.5873) = 5 * 1.259 = 6.295 cm (rounded to the first decimal place)

So, the base radius of the cylinder is approximately 6.3 cm.

in a continuous probability distribution, the random variable: group of answer choices can take on an infinite number of values. may have a probability greater than 1.00. has a limited number of values. is discrete.

Answers

The correct answer is option 1. In a continuous probability distribution, the random variable can take on an infinite number of values within a given range.

This range is typically represented by the interval between two points on the number line, such as 0 and 100. The probability of a particular value occurring is defined as the area under the curve of the probability density function for that distribution, rather than a single value.

Option 2, "may have a probability greater than 1.00" is incorrect as probabilities are always between 0 and 1, inclusive.

Option 3, "has a limited number of values" is incorrect as, by definition, continuous random variables can take on an infinite number of values.

Option 4, "is discrete" is incorrect as a continuous random variable is not limited to a finite or countable number of values.

Here we work in the system of integer polynomials. Those are polynomials of the Form f(x)=rnxn+···+r1x+r0 where every coefficient is an integer. General question: When does some combination of the polynomials ax + b and cx + d equal 1 ? That is, when do there exist integer polynomials P(x) and Q(x) with P(x)·(ax + b) + Q(x)·(cx + d) = 1 ? We concentrate here on cases when c = 0. (a) Prove: No combination of 2x + 5 and 3 can equal 1. That is, no integer polynomials P (x), Q(x) can satisfy: P (x)·2x + 5 + Q(x)·3 = 1. (b) Find a combination of 2x + 5 and 4 that equals 1. (c) Does some combination of 15x+9 and 25 equal 1? How about 15x+9 and 20? Explain your reasoning. (d) Investigate further examples of ax + b and d, deciding in each case whether 1 is a combination. What patterns do you detect? Can you prove that some of your observed patterns always hold true?

Answers

It appears that for any ax + b, a combination of ax + b and 2a+d equals 1. This can be proven by setting P(x) = -ax - b and Q(x) = 2a+d.

(a) No combination of 2x + 5 and 3 can equal 1.

Let P(x) and Q(x) be two integer polynomials such that P(x)·(2x + 5) + Q(x)·3 = 1.

This can be written as P(x)·2x + P(x)·5 + Q(x)·3 = 1.

Rearranging, we get P(x)·2x + (P(x)·5 + Q(x)·3) = 0

This implies that P(x)·2x = -(P(x)·5 + Q(x)·3).

Since both P(x) and Q(x) are integer polynomials, it follows that P(x)·2x and (P(x)·5 + Q(x)·3) are both integers.

However, this is impossible since the left hand side is an even integer, while the right hand side is an odd integer.

Therefore, no combination of 2x + 5 and 3 can equal 1.

(b) A combination of 2x + 5 and 4 that equals 1 is P(x) = -2x - 5 and Q(x) = 4.

(c) No combination of 15x+9 and 25 equals 1. However, a combination of 15x+9 and 20 equals 1. This can be seen by setting P(x) = -15x - 9 and Q(x) = 20.

(d) Some examples of ax + b and d combinations that equal 1 are:

2x + 5 and 4

3x + 4 and 7

4x + 3 and 9

5x + 2 and 11

It appears that for any ax + b, a combination of ax + b and 2a+d equals 1. This can be proven by setting P(x) = -ax - b and Q(x) = 2a+d.

The scale factor of the dilation is given by the equation s = 2.5

What is Dilation?

Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent

Given data ,

Let the triangle be represented as RST

Let the dilated triangle be represented as R'S'T'

Now , the coordinates of ΔRST is

The coordinate of R = R ( 0 , 4 )

The coordinate of S = S ( 2 , 4 )

The coordinate of T = T ( 2 , 2 )

And , the coordinates of ΔR'S'T' is

The coordinate of R' = R' ( 0 , 10 )

The coordinate of S = S ( 5 , 10 )

The coordinate of T = T ( 5 , 5 )

So , the dilation scale factor is given by coordinate of R' / coordinate of R

A real estate agent has 17 properties that she shows,  the probability of selling no more than 3 properties in one week is 0.0464 or 4.64%.

There are only two possible outcomes for each attribute. Selling one home does not affect the likelihood of selling another. Therefore, to answer this query, we employ the binomial probability distribution.

Binomial probability distribution

The probability of precisely x successes on n repeated trials is known as a binomial probability, and X can only have two possible outcomes.

[tex]P(X=x) = C_{n} , x.P^x.(1-P)^{n-x}[/tex]

Given by the following formula.

[tex]C_{n} , x = \frac{n!}{x! (n-x)!}[/tex]

And p is the probability of X happening.

n = 17

P = 0.4

P(X≤3) = P(X=0) + P(X=1) + P(X=2) + P(X=3)

In which,

[tex]P(X=x) = C_{n} , x.P^x.(1-P)^{n-x}[/tex]

[tex]P(X=x) = C_{n} , x.P^x.(1-P)^{n-x}\\P(X=0) = C_{17} ,0.(0.4)^0.(0.6)^{17} = 0.0002\\P(X=1) = C_{17} ,1.(0.4)^1.(0.6)^{16}=0.0019\\P(X=2) = C_{17} ,2.(0.4)^2.(0.6)^{15}=0.0102\\P(X=3) = C_{17} ,3.(0.4)^3.(0.6)^{14}=0.0341[/tex]

P(X≤3) = P(X=0) + P(X=1) + P(X=2) + P(X=3) = 0.0002 + 0.0019 + 0.0102 + 0.0341  = 0.0464

What is equation?

An algebraic equation, also known as a polynomial equation, is a mathematical equation of the form P=0, where P is a polynomial with coefficients in some field, most commonly the field of rational numbers. In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign.

Here,

Let's call the original value of x as X. Then, we can write the following equation:

X - X/6 - X/13 = 1000

Expanding the first two terms on the left-hand side:

X - X/6 - X/13 = 1000

7X/78 = 1000

X = 78 * 1000 / 7

X = 11142.85714

if the system has a radius of 40 cm, what is the tangential acceleration (in m/s2) of a point on its outermost edge at t = 0.5 s?

Answers

The angular acceleration of the system times the system's radius, which is 40 cm, or 0.4 m, gives rise to the tangential acceleration at the system's farthest edge at time t = 0.5 s. Thus, 0.4 m/s2 is the tangential acceleration.

The radius of the system multiplied by the system's angular acceleration gives the tangential acceleration of a point at its furthest edge. The system's radius in this instance is 40 cm, or 0.4 metres, and the time is 0.5 seconds. As a result, the tangential acceleration at time t = 0.5 s is equal to the system's angular acceleration times its radius, which is 0.4 m. We multiply the angular acceleration by the system's radius, which is 0.4 m, to determine the tangential acceleration. Thus, 0.4 m/s2 is the tangential acceleration at time t = 0.5 s. This indicates that a point on the system's outermost edge accelerates by 0.4.

Find an equation of the tangent plane to the given surface at the specified point.
z =( ex − y 5), (3, 3, 6)
Please explain steps

Answers

This is an equation is e⁻¹³⁸ˣ - 5e⁻¹³⁹ × 81y + z = 6

What do you mean by tangent?

In mathematics, a tangent is a line that touches a curve at a single point and has the same slope as the curve at that point. The tangent can be thought of as an approximation of the curve at the point where it touches it.

The concept of the tangent is used in calculus and other branches of mathematics to study the properties of curves and to analyze their behavior. The derivative of a function at a point is defined as the slope of the tangent to the curve of the function at that point. The derivative is a fundamental concept in calculus and is used to study the rate of change of a function, the optimization of functions, and to solve problems in many different fields.

To find the equation of the tangent plane to the surface z = e^(x - y^5) at the point (3, 3, 6), we need to find the normal vector of the surface at that point, and use that to find the equation of the plane.

The normal vector can be found using the gradient of the surface, which is given by the partial derivatives of the function:

∇f = ∇(e^(x - y^5)) = (e^(x - y^5), -5e^(x - y^5)y^4, 1)

Evaluating this at the point (3, 3, 6), we get:

∇f(3, 3, 6) = (e^(3 - 3^5), -5e^(3 - 3^5)3^4, 1) = (e^-138, -5e^-138 * 81, 1)

So the normal vector of the surface at the point (3, 3, 6) is (e^-138, -5e^-138 * 81, 1).

To find the equation of the tangent plane, we need to find a point on the plane, and use that along with the normal vector. We already know that the point (3, 3, 6) is on the surface, so we can use that as a point on the plane.

Using the point-normal form of a plane, the equation of the tangent plane is given by:

ax + by + cz = d

Where (a, b, c) is the normal vector and (x⁰, y⁰, z⁰) is a point on the plane.

Substituting the values, we get:

e⁻¹³⁸ˣ - 5e⁻¹³⁹ × 81y + z = 6

This is the equation of the tangent plane to the surface z = e^(x - y^5) at the point (3, 3, 6).

Find the unit vectors that are parallel to the tangent line to the parabola y = x2 at the point (6, 36).

Answers

The tangent line to the parabola y = x² at the point (6, 36) is (0.141, 1.68)

How to find the unit vector parallel to the tangent line

The equation of the tangent line at the point (6, 36) can be found using the derivative of the function and the point-slope form of a line:

f(x) = x²

f'(x) = 2x

y = f'(x) * (x - 6) + 36

Substituting f'(x) = 2x,

y = 2x * (x - 6) + 36

Now, we can find a unit vector that is parallel to this line by finding a non-zero multiple of the direction vector of the line, which is (1, 2x), and normalizing it.

To normalize, we divide by the magnitude, which is sqrt(1^2 + (2x)^2) = sqrt(1 + 4x^2).

Let's use x = 6:

y = 2 * 6 * (x - 6) + 36

y = 72

So, the direction vector is (1, 12) and its magnitude is sqrt(1 + 144) = sqrt(145) = 7.07.

The unit vector that is parallel to the tangent line is (1/7.07, 12/7.07) = (0.141, 1.68).

Our constant (last term) is -27. The factors of -27 can be ±1, ±3, ±9, ±27

Our lead coefficient is 2. The factors of 2 can be ±1 and ±2.

Hence:

[tex]\displaystyle{\text{possible rational roots} = \dfrac{\pm 1, \pm 3, \pm 9, \pm 27}{\pm 1, \pm 2}}\\\\\displaystyle{\text{possible rational roots} = \pm 1, \pm \dfrac{1}{2}, \pm 3, \pm \dfrac{3}{2}, \pm 9, \pm \dfrac{9}{2}, \pm 27, \pm \dfrac{27}{2}}[/tex]

All of these are possible roots, meaning that not all of them are real roots of the equation, just a possibility.

What is the Greatest Common Factor?

The greatest common factor, which is the product of two or more numbers, is the largest number (GCF). A natural number is created by dividing them by the biggest number (factor). There are a few factors that both share once all the number's factors have been identified. The greatest common factor is the one with the largest number among the common factors. The highest common factor is another name for the GCF (HCF)

suppose that you pull out a toy at random, and you observe only the color, noting that it is red. conditional on just this information, what is the probability that the toy is not cool?

Answers

Without additional information, it is impossible to determine the probability that the toy is not cool.

Without additional information, it is impossible to determine the probability that the toy is not cool. This is because the color of the toy does not provide any information about its coolness. For example, a red toy could be a cool action figure or a boring stuffed animal. Therefore, the color of the toy does not provide any insight into its coolness, and thus any probability assigned to the toy being not cool would be purely speculative and not based on any information. In order to determine the probability that the toy is not cool, we would need additional information, such as what the toy is, what its features are, or who makes it.

Penny's parents have agreed to loan her $4500 to pay her tuition. They are charging her an interest rate of
3% per annum, compounded monthly. Penny has arranged to pay them $160 per month to pay off the loan.
a) how long it takes Penny to pay off the loan b) the amount of her final payment

Answers

Answer:

$157.92.

Step-by-step explanation:

a) To calculate how long it takes Penny to pay off the loan, we can use the formula:

n = log(P/A) / log(1 + r/12),

where n is the number of months, P is the initial loan amount ($4500), A is the monthly payment ($160), and r is the annual interest rate (3%).

n = log(4500/160) / log(1 + 0.03/12)

n = log(28.125) / log(1.0025)

n = 3.7062

Rounding up, it takes Penny 4 months to pay off the loan.

b) To calculate the amount of Penny's final payment, we can use the formula:

P = A * (1 - (1 + r/12)^-n),

where P is the remaining balance, A is the monthly payment ($160), n is the number of months (4), and r is the annual interest rate (3%).

P = 160 * (1 - (1 + 0.03/12)^-4)

P = 160 * (1 - (1.0025)^-4)

P = $157.92

Therefore, it takes Penny 4 months to pay off the loan and her final payment is $157.92.

A commission is a percentage of a sale. People who conduct sales earn a portion of their income based on how much they sell. Zachary earned 31% commission on a sale of $635. What is the amount of the commission?​

Answers

The amount of the commission earned by Zachary on the $635 sale is $196.85.

What is the amount of the commission earned by Zachary?

A commission is a percentage of a sale earned by a sales person.

Given that;

Commission = 31%Sale price = $635Commission amount = ?

Since commission is a percentage of a sale earned

Commission amount = sale price × commission

Plug in the given values and simplify

Commission amount = $635 × 31%

Note that; 31% is the same as 31/100

Commission amount = $635 × 31/100

Commission amount = $635 × 0.31

Multiply $635 and 0.31

Commission amount = $196.85

Therefore, the amount of commission is $196.85.

Answers

The size squares that should be cut from the cardboard is 0.692 inch

What size squares should be cut from the cardboard?

Represent the cut-out with x

So, we have the following volume equation:

V(x) = (12 - 2x)(15 - 2x)x

The volume is 100

So, we have

(12 - 2x)(15 - 2x)x = 100

Using a graphing calculator, we have

x = 0.692

Hence, the solution is 0.692

Use the graph of the function to determine the indicated limit, if it exists. lim f(x) Select the correct choice below and fill in any answer boxes in your choice. A. lim f(x) = B. The limit does not exist and is neither conor -

Answers

lim (x → a) f(x) = ∞ , The limit does not exist and is neither ∞ nor - ∞

What is function?

The vertical line test is used to verify function. That is, a graph must have a unique y value for it to be referred to as a function for a certain (unique) value of x. If for a particular x, and y values are coming it means it is not a function. If it crosses y-axis twice it means for a particular x value , two different value of y will exist. And that is not possible for a function

From the graph, we know that limit at point a is:

lim (x→a) f(x) exists if and only if

lim (x →a⁺) f(x) = lim (x→a⁻) f(x) and ≠ ∞

∴ right hand side limit = left hand side limit

lim (x →a⁺) f(x) = - ∞

lim (x →a⁻) f(x) = - ∞

∴ lim (x → a) f(x) = ∞

thus, option B is the correct answer.

The limit does not exist and is neither ∞ nor - ∞
