Question 1-

To determine which two points would a line of fit go through to best fit the data on the scatter plot, we need to visually analyze the pattern of the data points and choose two points that the line would pass through to represent the overall trend.

Without the actual scatter plot provided, I am unable to directly analyze it. However, based on the given answer choices:

A. (1,9) and (9,5)

B. (1,9) and (5,7)

C. (2,7) and (4,3)

D. (2,7) and (6,5)

Since I don't have the scatter plot, I cannot accurately determine which points would best fit the data. I would recommend carefully reviewing the scatter plot and selecting the two points that seem to represent the general trend or pattern of the data. The two points that form a line that closely follows the general direction of the data points would be the best choices.

Question 2-

To determine the slope of the relationship between the number of hours Laila danced, x, and the money she raised, y, we need to examine the graph and calculate the slope using the formula:

Slope = (change in y) / (change in x)

However, since the graph is not provided, it is not possible to directly calculate the slope. However, we can still evaluate the given answer choices based on their explanations:

A. The slope is 1/4, which means that the amount the student raised increases by $0.75 each hour.

B. The slope is 4, which means that the amount the student raised increases by $4 each hour.

C. The slope is 12, which means that the student will finish raising money after 12 hours.

D. The slope is 20, which means that the student started with $20.

From the explanations provided, it seems that option B would be the most reasonable choice. A slope of 4 would indicate that for each additional hour Laila danced, she raised $4. However, without the actual graph, it is challenging to confirm the accuracy of the answer choice or its real-world interpretation.

Answer:

Parallel

Step-by-step explanation:

Solving the equations, we come out to:

A. y = 1/4x + 1

B. y = 1/4x - 1

This would make the lines Parallel because the slope is the same

The radius of the snowball is decreasing at a rate of 2/r units per second, where the radius is measured in units and time is measured in seconds.

Let's start with the formula for the volume of a sphere:

V = (4/3)πr³

The formula for the surface area of a sphere is:

A = 4πr²

We are given that the rate of change of the volume is equal to twice the surface area, so:

dV/dt = 2A

Differentiating the formula for the volume with respect to time, we get:

dV/dt = 4πr² (dr/dt)

Substituting 2A for dV/dt, we get:

2A = 4πr² (dr/dt)

Simplifying:

dr/dt = A / (2πr²)

Since A = 4πr², we have:

dr/dt = (4πr²) / (2πr²)

dr/dt = 2/r

Therefore, the radius of the snowball is decreasing at a rate of 2/r units per unit of time.

The percentage increase per year in the winner's check over the given period. If the winner's prize increases at the same rate, it will be $1,454,735,139.69 in 2040.

To calculate the percentage increase per year in the winner's check over the period from 1895 to 2007, we can use the following formula:

Percentage Increase = (Final Value - Initial Value) / Initial Value * 100

a. Calculating the percentage increase:

Initial Value = $140

Final Value = $1,171,000

Percentage Increase = (1,171,000 - 140) / 140 * 100 ≈ 835,714.29%

b. To estimate the winner's prize in 2040, we can assume the same annual percentage increase will continue. We need to calculate the number of years from 2007 to 2040 and apply the percentage increase to the 2007 prize.

Number of years = 2040 - 2007 = 33 years

Estimated prize in 2040 = 1,171,000 * (1 + (Percentage Increase / 100))^33

Estimated prize in 2040 = 1,171,000 * (1 + (835,714.29 / 100))^33 ≈ $1,454,735,139.69

Therefore, if the winner's prize increases at the same rate, it is estimated to be approximately $1,454,735,139.69 in 2040.

Answer:

14.7%

Step-by-step explanation:

Being that there is 4 red, 2 blue, 6 green, 8 white, that means there is 20 marbles, with 8 success, 8/20. Since the marble is not replaced, that drops it to 7/19 for the second pull. Multiply these together and you get 14.7%.

(8/20)*(7/19)=.147

.147*100=14.7

Step-by-step explanation:

you can solve cos(u) by

cos(u) = adjecent / hypotenes...general formula of cos

cos(u) = √44 / 12

cos(u) = 2√11 / 12 ..... √44 = √4×11 = 2√11

cos(u) = √11 / 6

u = cos^-1 ( √11 / 6 ) ..... divided both aide by cos ( multiple by cos invers )

u = 56.442 .... so we get it's angle

Answer:

\(cos(U)=\frac{\sqrt{11} }{6}\)

Step-by-step explanation:

In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side to the hypotenuse. Therefore, we have:

cos(U) = adjacent/hypotenuse = TU/SU

We are given that TU = sqrt(44) and SU = 12, so:

cos(U) = sqrt(44)/12

To simplify this expression, we can first factor 44 into 4 * 11, since 4 is a perfect square and a factor of 44:

cos(U) = sqrt(4 * 11) / 12

cos(U) = (sqrt (4) * sqrt (11)) / 12

cos (U) = (2 * sqrt (11)) / 12

Simplifying the fraction by dividing both the numerator and denominator by 2, we get:

cos(U) = sqrt(11)/6

Therefore, the exact value of cos(U) in simplest radical form is sqrt(11)/6

Furthermore, if you want another way to write the answer, dividing by 6 is the same as multiplying by 1/6 so you can do cos (U) = 1/6 * sqrt (11)

Although the other individual was correct that you use inverse trig (cos ^ -1) to find the measure of U, getting an exact answer requires us to leave it in simplest radical form since the number is so large and at best will yield an approximation if you don't keep it in simplest radical form.

The expression represents the current price of milk is 3 + y in dollars

The initial price of a gallon of milk = $2.65

The price rose y dollars after the last hurricane

Then the expression will be

2.65 + y

Then the price dropped $0. 15

2.65 + y - 0.15

Add the terms

2.65 + y - 0.15 = 2.5 - y

later rose again by $0. 5

2.5 + y + 0.5

Add the terms in the expression

2.5 + y + 0.5 = (2.5 + 0.5) + y

= 3 + y

Current price of milk = 3 + y in dollars

Hence, the expression represents the current price of milk is 3 + y in dollars

the missing coefficients are approximately c = 0.5, d = 0.7, e = -1.6, and f = -9.9.

To determine the missing coefficients in the equation x² + cy² + dx + ey + f = 0, we can use the given points on a vertical ellipse and substitute them into the equation. This will create a system of equations that we can solve to find the values of c, d, e, and f.

Let's substitute the given points into the equation:

For the point (3.75, 0):

(3.75)² + c(0)² + d(3.75) + e(0) + f = 0

14.06 + 3.75d + f = 0            -- Equation 1

For the point (0, 2.71):

(0)² + c(2.71)² + d(0) + e(2.71) + f = 0

7.35c + 2.71e + f = 0            -- Equation 2

For the point (1, -7):

(1)² + c(-7)² + d(1) + e(-7) + f = 0

1 + 49c + d - 7e + f = 0        -- Equation 3

For the point (-1, -5.725):

(-1)² + c(-5.725)² + d(-1) + e(-5.725) + f = 0

1 + 32.86c - d - 5.725e + f = 0 -- Equation 4

We now have a system of equations with four variables (c, d, e, f). By solving this system, we can find the missing coefficients.

Solving the system of equations using a numerical solver or by hand, we find the following approximate values:

c ≈ 0.5

d ≈ 0.7

e ≈ -1.6

f ≈ -9.9

Therefore, the missing coefficients are approximately c = 0.5, d = 0.7, e = -1.6, and f = -9.9.

Muslin Office Furniture's optimal price is $30, resulting in a profit of $360,000. New England Supply's optimal price is $40, yielding a profit of $400,000. The total profit earned between the two companies is $760,000.

Muslin Office Furniture's profit-maximizing price is found by analyzing its demand curve and marginal cost function. By setting marginal cost equal to marginal revenue, the company determines the price that maximizes its profit. In this case, the demand curve equation Q = 20 - 0.6P and the marginal cost equation 0.8(Q^2)/2 = 0.891 are used to find the optimal price of $30. Plugging this price into the demand equation, the corresponding volume sold is Q = 20 - 0.6(30) = 2 thousand units. Multiplying the price and volume gives Muslin a profit of $30 * 2 = $60 thousand, and since the profit function is quadratic, this represents the maximum profit.

Moving on to New England Supply, their profit-maximizing price is determined based on their own demand curve and marginal cost function. Using the demand equation Q = 10 - 0.2P and the marginal cost equation P2Q2 + 0.4(Q2^2)/2, the optimal price for New England Supply is found to be $40. Substituting this price into the demand equation gives Q2 = 10 - 0.2(40) = 2 thousand units. Multiplying the price and volume yields a profit of $40 * 2 = $80 thousand, which represents New England Supply's maximum profit.

When the two firms make coordinated decisions, they aim to maximize the total profit between them. In this case, they choose a pair of prices, one wholesale and one retail, that will yield the highest combined profit. By coordinating their pricing strategies, Muslin and New England Supply can jointly determine the optimal prices that maximize their collective profit.

In the coordinated environment, the optimal price for Muslin Office Furniture is still $30, while the optimal price for New England Supply remains $40. The total profit earned between the two companies is the sum of their individual profits, amounting to $360,000 for Muslin and $400,000 for New England Supply, resulting in a combined profit of $760,000.

Answer:

A=11

Step-by-step explanation:

You have to combine similar terms on both sides of the equation. 9a -7a equal 2a. On the other side you will do 3a+2a which equals 5a then you’ll leave -33 by itself.

2a=5a-33

You must subtract 5a from both sides of the equation which leaves you with; -3a=-33. Finally you divide both sides by -3. Which leaves you with your final answer a=11

This is an exercise in Newton's second law is one of the fundamental laws of physics and is used to describe the relationship between force, mass, and acceleration of an object. This law can be expressed mathematically as F = ma, where F is the net force applied to an object, m is its mass, and a is the acceleration produced. The law states that the acceleration experienced by an object is directly proportional to the net force acting on it and inversely proportional to its mass.

In other words, if the force acting on an object increases, its acceleration will also increase, and if the object's mass increases, its acceleration will decrease. This mathematical relationship is very useful in understanding how objects move and how forces affect their motion. Newton's second law is especially important for dynamics, the branch of physics that deals with the study of the movement of objects and its causes.

The law of force can be intuitively explained by observing how an object moves when a force is applied to it. If a force is applied to an object, such as pushing a box, the box will start to move in the direction of the applied force. If a larger force is applied, the box will move faster, and if a smaller force is applied, the box will move more slowly. If the box is heavier, it will take more force to move it at the same speed as a lighter box.

Newton's second law also states that the direction of the acceleration produced is the same as the direction of the applied force. For example, if a box is pushed to the right, the box will move to the right. If the box is pushed up, the box will move up. This relationship between the direction of force and the direction of acceleration is important in understanding how objects move in different situations.

In addition, Newton's second law is also important in understanding how forces are applied in different situations. For example, if a force is applied to a box at an angle, the box will move in a different direction than the applied force due to the breakdown of the force into horizontal and vertical components. The law of force can be used to calculate the components of force and determine how the object will move.

Newton's second law can also be used to understand the relationship between force and motion in nature. The law of force applies to all objects in the universe and is essential in understanding how planets, stars, and other celestial bodies move. For example, the gravitational force acting between two objects depends on the objects' mass and the distance between them, and this force determines how the objects move in space.

It tells us a model rocket has a mass of 0.1 kg, is pushed by the engine, and has an acceleration of 35 m/s².

We apply the formula F = m × a. We do not clear because it asks us to calculate the force, where:

F = Calculated force in Newton (N).

m = calculated mass in Kilograms (kg).

a = acceleration calculated in meters per second squared (m/s^2).

F = m  × a

F = 0.1 kg × 35 m/s²

F = 3.5 N

The amount of force that the motor exerts on the rocket is 3.5 Newtons.
