Solving the provided question, we can say that the highest number bouquets she can make without having any flowers left is calculated by Highest Common Factor so, HCF of 56, 48 and 16 is 8

In mathematics, the highest positive integer that divides the corresponding integers is known as the greatest common divisor of two or more non-zero integers. The greatest common factor (HCF) of two or more numbers is the sum of those two or more numbers. As a result, it is frequently referred to as the largest common divisor (GCF). Take the prime factors of the two (or more) integers and determine the shared prime factors to determine the greatest common divisor. Following that, the sum of common prime factors is the greatest common divisor. A specified number divided by the biggest integer results in the greatest common divisor.

In the preceding equation the measure of the smallest angle is 52° in length.

Internal angles 2 and 3 are alternate options. Two angles that share a vertex and a side but no interior points in common. two angles that don't have any shared interior points but do have a common vertex and side.

We know that a triangle has 180 angles altogether.

So, 2x + 3x - 11 + 2x + 9 = 180

7x - 2 = 180

7x = 180 + 2

x = 182 / 7

x = 26

Now, magnitude of angles = 2x = 2(26) = 52  [ Smallest ]

3x - 11 = 3(26) - 11 = 78 - 11 = 67  [ Largest ]

2x +9 = 2(26) + 9 = 52 + 9 = 61

The cost of one package of tulips bulbs = $10

And, The cost of one package of crocus bulbs = $14

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Perry sold 7 packages of tulip bulbs and 6 packages of crocus bulbs for a total of $166.

And, Scott sold 3 packages of tulip bulbs and 6 packages of crocus bulbs for a total of $126.

Now, Let the cost of one package of tulips bulbs = x

And, The cost of one package of crocus bulbs = y

Hence, We can formulate;

7x + 6y = 166  .. (i)

3x + 6y = 126  .. (ii)

Now, Find value of 6y from (i) and substitute in (ii);

From (i)

6y = 166 - 7x

From (ii),

3x + (166 - 7x) = 126

166 - 126 = 4x

40 = 4x

x = 10

From (i);

6y = 166 - 7 × 10

6y = 166 - 70

6y = 84

y = 14

Thus, the cost of one package of tulips bulbs = $10

Particle moves with its position given by x= cos(2t) and y= sin (t), where positions are given in feet from the origin and time t is in seconds. The speed of the particle at any time t is v = \(\sqrt\)(4sin²(2t) + cos²(t)).

For the speed of the particle, we can calculate the magnitude of its velocity vector.

The velocity vector can be obtained by differentiating the position vector with respect to time.

We have the position of the particle as x = cos(2t) and y = sin(t), we can differentiate these equations to find the corresponding velocity components:

vx = dx/dt = -2sin(2t)

vy = dy/dt = cos(t)

The magnitude of the velocity vector (v) is given by the square root of the sum of the squares of its components:

\(\sqrt\)(vx² + vy²) = \(\sqrt\)((-2sin(2t))² + (cos(t))²)

Simplifying this expression:

v = \(\sqrt\)(4sin²(2t) + cos²(t))

This is the speed of the particle at any given time t.

Note that the speed is not constant but varies with time due to the periodic nature of the sine and cosine functions.

The rate of change of radius of the circle when the radius of the circle is 44 feet is 0.64 ft/s.

The area of the circle with radius R us given by,

A = πR²

It is given that the area is increasing at a constant rate of 178 square feet per second.

dA/dt = 178 ft²/s

Also, A = πR²

Differentiating A with respect to time,

dA/dt = 2πR.dR/dt

The rate of change of the radius is asked when the radius is 44 feet.

So, putting R = 44 ft.

dA/dt = 2π(44)dR/dt

178 = 2π(44)dR/dt

dR/dt = 0.64 ft/s

So, the rate of change of radius is 0.64 ft/s.

Answer:

Step-by-step explanation:

The ones digit in the number 22011 is 8.

To find the ones digit in the number 22011, we can observe a pattern by looking at the ones digits of powers of the number.

Let's start by calculating the powers of 2, starting from smaller exponents:

2^1 = 2

2^2 = 4

2^3 = 8

2^4 = 16

2^5 = 32

2^6 = 64

2^7 = 128

2^8 = 256

2^9 = 512

2^10 = 1024

2^11 = 2048

Now, if we analyze the ones digit of each power of 2, we can see a repeating pattern:

2^1 = 2

2^2 = 4

2^3 = 8

2^4 = 6

2^5 = 2

2^6 = 4

2^7 = 8

2^8 = 6

2^9 = 2

2^10 = 4

2^11 = 8

From the pattern above, we can notice that the ones digit repeats every four powers: 2, 4, 8, 6. Therefore, to find the ones digit of 2^11 (22011), we need to determine the remainder when 11 is divided by 4.

11 divided by 4 gives a remainder of 3. This means that we need to look at the third position in the repeating pattern, which is 8.

Hence, the ones digit in the number 22011 is 8.

Answer:

x = 68°

Step-by-step explanation:

Let us solve the question

In the given figure

∵ The ray WD bisects ∠ZWN

→ That means it divides the angle into two equal angles, ∠ZWD and ∠DWN

∴ m∠ZWD = m∠DWN

∵ m∠ZWD = 5v - 7

∵ m∠DWN = 4v + 8

→ Equate the measures of the two angles

∴ 5v - 7 = 4v + 8

→ Add 7 to both sides

∵ 5v - 7 + 7 = 4v + 8 + 7

∴ 5v = 4v + 15

→ Subtract 4v from both sides

∵ 5v - 4v = 4v - 4v + 15

∴ v = 15

∵ x = m∠ZWD

∴ x = 5v - 7

→ Substitute v by 15

∵ x = 5(15) - 7

∴ x = 75 - 7

∴ x = 68°

You’ve studied and now you’re geared up for the ACT math section (whoo!). But are you ready to take on the most challenging math questions the ACT has to offer? Do you want to know exactly why these questions are so hard and how best to go about solving them? If you’ve got your heart set on that perfect score (or you’re just really curious to see what the most difficult questions will be), then this is the guide for you.

We’ve put together what we believe to be the most 21 most difficult questions the ACT has given to students in the past 10 years, with strategies and answer explanations for each. These are all real ACT math questions, so understanding and studying them is one of the best ways to improve your current ACT score and knock it out of the park on test day.

Brief Overview of the ACT Math Section

Like all topic sections on the ACT, the ACT math section is one complete section that you will take all at once. It will always be the second section on the test and you will have 60 minutes to completed 60 questions.

The ACT arranges its questions in order of ascending difficulty. As a general rule of thumb, questions 1-20 will be considered “easy,” questions 21-40 will be considered “medium-difficulty,” and questions 41-60 will be considered “difficult.”

The way the ACT classifies “easy” and “difficult” is by how long it takes the average student to solve a problem as well as the percentage of students who answer the question correctly. The faster and more accurately the average student solves a problem, the “easier” it is. The longer it takes to solve a problem and the fewer people who answer it correctly, the more “difficult” the problem.

(Note: we put the words “easy” and “difficult” in quotes for a reason—everyone has different areas of math strength and weakness, so not everyone will consider an “easy” question easy or a “difficult” question difficult. These categories are averaged across many students for a reason and not every student will fit into this exact mold.)

All that being said, with very few exceptions, the most difficult ACT math problems will be clustered in the far end of the test. Besides just their placement on the test, these questions share a few other commonalities. We'll take a look at example questions and how to solve them and at what these types of questions have in common, in just a moment.

But First: Should You Be Focusing on the Hardest Math Questions Right Now?

If you’re just getting started in your study prep, definitely stop and make some time to take a full practice test to gauge your current score level and percentile. The absolute best way to assess your current level is to simply take the ACT as if it were real, keeping strict timing and working straight through (we know—not the most thrilling way to spend four hours, but it will help tremendously in the long run). So print off one of the free ACT practice tests available online and then sit down to take it all at once.

Once you’ve got a good idea of your current level and percentile ranking, you can set milestones and goals for your ultimate ACT score. If you’re currently scoring in the 0-16 or 17-24 range, your best best is to first check out our guides on using the key math strategies of plugging in numbers and plugging in answers to help get your score up to where you want it to. Only once you've practiced and successfully improved your scores on questions 1-40 should you start in trying to tackle the most difficult math problems on the test.

If, however, you are already scoring a 25 or above and want to test your mettle for the real ACT, then definitely proceed to the rest of this guide. If you’re aiming for perfect (or close to), then you’ll need to know what the most difficult ACT math questions look like and how to solve them. And luckily, that’s exactly what we’re here for.Step-by-step explanation:

In Mathematics and Geometry, the rotation of a point 180° about the origin in a clockwise or counterclockwise direction would produce a point that has these coordinates (-x, -y).

Furthermore, the mapping rule for the rotation of a geometric figure about the origin is given by this mathematical expression:

(x, y)                                            →            (-x, -y)

Coordinates of point A (2, 1)  →  Coordinates of point A' = (-2, -1)

Coordinates of point B (4, -5)  →  Coordinates of point B' = (-4, 5)

In conclusion, this transformation rule (x, y) → (-x, -y) is used for the rotation of a geometric figure about the origin in a clockwise or counterclockwise (anticlockwise) direction.

Y_1, Y_2, ..., Y_n are a random sample from a Laplace distribution with density function f(y|θ) = (1/2θ)e^(-|y|/θ) for -∞ < y < ∞, where θ > 0. The first two moments of the distribution are E(Y) = 0 and E(Y^2) = 2θ^2. The likelihood function of the sample is L(θ|y) = (1/2^nθ^n)e^(-∑|y_i|/θ).

a) The likelihood function is the product of the individual probability density functions for each observation. So, for a sample of size n, the likelihood function can be expressed as L(θ|y) = ∏(1/2θ)e^(-|y_i|/θ), i=1 to n. Simplifying this expression, we get L(θ|y) = (1/2^nθ^n)e^(-∑|y_i|/θ).

b) The sum of absolute values of the observations, ∑|y_i|, is a sufficient statistic for θ.

c) To find the maximum likelihood estimator (MLE) of θ, we differentiate the likelihood function with respect to θ and set it equal to zero. Solving for θ, we get the MLE as θ = ∑|y_i|/n.

d) The standard deviation of the Laplace distribution is given by σ = √(2)θ. Therefore, the MLE of the standard deviation is √(2)(∑|y_i|/n).

e) The method of moments estimator of θ is obtained by equating the sample mean absolute deviation to the population mean absolute deviation, which gives θ = ∑|y_i|/n.

f) To show that the MLE of θ is a minimum variance unbiased estimator, we can use the Fisher information. The Fisher information for θ is given by I(θ) = n/θ^2. The variance of the MLE is then given by Var(θ) = 1/I(θ) = θ^2/n. Therefore, the MLE is unbiased and has minimum variance. The variance of Y is Var(Y) = 4θ^2, so Var(X) = Var(Y)/n = 4θ^2/n.

To fully define a vector quantity, you must specify Magnitude, Direction and Reference Point

1. Magnitude: The magnitude of a vector represents the size or length of the vector. It is typically denoted by a scalar value and can be expressed in appropriate units. For example, if you're describing a velocity vector, the magnitude might be 10 meters per second.

2. Direction: The direction of a vector indicates the orientation or angle at which the vector is pointed. It can be specified using various methods, such as angles measured relative to a reference axis or using directional descriptors like north, south, east, or west. For example, a velocity vector might be pointing at an angle of 30 degrees east of north.

3. Reference Point or Origin: A vector is typically defined with respect to a reference point or origin. This point serves as a starting point for measuring the vector's position or displacement. It helps establish a frame of reference for interpreting the vector's direction and magnitude. For example, if you're describing a displacement vector, you would need to specify the reference point from which the displacement is measured.

By specifying these three components—magnitude, direction, and reference point—you can fully define a vector quantity and convey all the necessary information about its properties and characteristics.

Step-by-step explanation:

To find the points on the curve where the tangent line has the largest slope, we need to determine the critical points of the curve, which are the points where the derivative of the function is equal to zero or undefined. The largest slope corresponds to the steepest tangent line on the curve.

To find the largest slope, we need to find the maximum or minimum value of the derivative. This can be done by evaluating the derivative of the curve and finding its critical points. The critical points where the derivative is equal to zero or undefined represent the points on the curve where the tangent line has the largest slope.

By analyzing the critical points and evaluating the derivative, we can determine the specific points on the curve where the tangent line has the largest slope and calculate the corresponding value of the largest slope.
