As a result, g(x) and h(x) have the following composition: f(x) = 2 as to determine the composition of g(x) and h(x) .

With the input (the x-value) drawn on the x plane and the output (the y-value) written on the vertical axis, functions can be represented graphically. Understanding a function's behaviour, for example, if it is going up or down, and locating significant characteristics like peaks and minima, can be done by looking at its graph. Many branches of arithmetic, as well as physics, construction, computer science, sociology, and a wide range of other disciplines, use functions. They are a crucial tool for problem-solving across a broad spectrum and for simulating real-world occurrences.

given

We may utilise the distributive property of multiplication to multiply the two functions:

\(g(x) * h(x) = (x - 2) * 4\)

= 4x - 8

Hence, f(x) = 4x - 8 is the result of the two functions' product.

Composition: To determine the composition of g(x) and h(x), we must replace every instance of x with h(x) in g(x):

\(g(h(x)) = g(4) (4)\)

= 4 - 2

= 2

This is true because a probability distribution is a mathematical function that provides the probabilities of occurrence of different possible outcomes in an experiment.

The area under the probability distribution is a measure of the probability of all the possible outcomes. Since the sum of all the probabilities of all the possible outcomes must be 1, the total area under the probability distribution must also be 1. This is because the probability of an event happening is the area under the curve of the probability distribution at that event. Thus, the total area under the probability distribution must always equal 1.

It will take approximately 3.33 hours for both persons working together to complete the job.

What is distance?

Distance is the measure of how far apart two objects or locations are from each other. It is usually measured in units such as meters, kilometers, miles, or feet.

To solve this problem, we can use the following formula:

1 / T = 1 / t1 + 1 / t2

Where T is the time it takes for both persons working together to complete the job, t1 is the time it takes for the first person to complete the job alone, and t2 is the time it takes for the second person to complete the job alone.

Plugging in the given values, we get:

1 / T = 1 / 5 + 1 / 10

Simplifying the right side, we get:

1 / T = 3 / 10

Multiplying both sides by 10T, we get:

10 = 3T

Dividing both sides by 3, we get:

T = 10 / 3 = 3.33 hours

Therefore, it will take approximately 3.33 hours for both persons working together to complete the job.

Answer:

this is true, I think so...

Answer: Yes.

Step-by-step explanation:

Two intersecting lines determine a plane. If you hold two pencils so that they cross each other, there’s only one place a flat plane can be placed so that it rests on both pencils. Which lines are always co planar? Two lines in three-dimensional space are coplanar if there is a plane that includes them both.

Answer:

In theory, yes.

Step-by-step explanation:

"If two lines intersect, then exactly one plane contains the lines." Now, each line contains two points, and according to another theorem in my book: "If two lines intersect, then they intersect in exactly one point." and three noncollinear points define a plane.

The solution to the given system of equations is x = 2, y = -1, and z = 1.

To solve the system of equations, we can use methods such as substitution or elimination. Here, we will use the method of elimination to find the values of x, y, and z.

First, let's eliminate the variable x by multiplying equation (1) by 2 and equation (3) by -1. This gives us:

2x + 4y - 2z = -6 (4)

-x + y - z = -4 (5)

Next, we can subtract equation (5) from equation (4) to eliminate the variable x:

5y - z = 2 (6)

Now, we have a system of two equations with two variables. Let's eliminate the variable z by multiplying equation (2) by 2 and equation (6) by 1. This gives us:

4x - 2y + 2z = 10 (7)

5y - z = 2 (8)

Adding equation (7) and equation (8), we can eliminate the variable z:

4x + 5y = 12 (9)

From equation (6), we can express z in terms of y:

z = 5y - 2 (10)

Now, we have a system of two equations with two variables again. Let's substitute equation (10) into equation (1):

x + 2y - (5y - 2) = -3

x - 3y + 2 = -3

x - 3y = -5 (11)

From equations (9) and (11), we can solve for x and y:

4x + 5y = 12 (9)

x - 3y = -5 (11)

By solving this system of equations, we find x = 2 and y = -1. Substituting these values into equation (10), we can solve for z:

z = 5(-1) - 2

z = -5 - 2

z = -7

Therefore, the solution to the given system of equations is x = 2, y = -1, and z = -7.

Step-by-step explanation:

There is approximately a 60.3% chance of losing one or more friends when distributing the candies under these conditions.

To calculate the probability of losing one or more friends when distributing the candies, we need to consider the distribution of the red candies among your friends.

Since the bag contains 64 candies and exactly 8 of them are red, the probability of picking a red candy at random from the bag is 8/64 = 1/8.

Now, let's consider the scenario where you give each friend 8 candies. The probability of a friend not receiving a red candy can be calculated by subtracting the probability of them receiving a red candy from 1.

For each friend, the probability of not receiving a red candy is (7/8), as there are 7 red candies left in the bag out of the remaining 56 candies (64 total - 8 red).

Since the candies are identically wrapped, the probabilities are the same for each friend.

To calculate the probability of losing one or more friends, we need to calculate the complement probability, which is the probability that no friend loses out on a red candy.

The probability of no friend losing out on a red candy is (7/8) for each friend.

As we have 8 friends, the overall probability is\((7/8)^8.\)

Finally, the probability of losing one or more friends is equal to 1 minus the probability of no friend losing out on a red candy:

Probability of losing one or more friends \(= 1 - (7/8)^8\)  

Calculating this, we find:

Probability of losing one or more friends ≈ 0.603

Answer:

We can use the formula for the length of an arc of a circle, which is:

length of arc = (angle/360) × 2πr

where angle is the angle subtended by the arc at the center of the circle, r is the radius of the circle, and π is approximately 3.14.

In this problem, the angle subtended by the arc at the circumference of the circle is 86 degrees. Since the radius of the circle is 8 cm, the diameter is 2 × 8 = 16 cm, and the circumference is 2πr = 2π(8) = 16π cm.

Using the hint given in the problem, we can find the angle subtended by the arc at the center of the circle:

angle at center = 2 × angle at circumference

= 2 × 86

= 172 degrees

Substituting into the formula, we have:

length of arc = (172/360) × 2π(8)

≈ 7.5 cm

Rounding to the nearest whole number, the length of the arc is 8 cm.

Saman's income needs to increase by $500.00 for her to continue purchasing 100 gallons of gasoline and running 10 loads of laundry each month.

To calculate how much Saman's income needs to increase, we need to determine the total cost of gasoline and laundry before and after the price changes.

Before the price increase:

Cost of gasoline: 100 gallons × $10.00/gallon = $1000.00

Cost of laundry: 10 loads × $0.50/load = $5.00

Total cost before the price increase: $1000.00 + $5.00 = $1005.00

After the price increase:

Cost of gasoline: 100 gallons × $15.00/gallon = $1500.00

Cost of laundry: 10 loads × $0.50/load = $5.00

Total cost after the price increase: $1500.00 + $5.00 = $1505.00

To maintain the same consumption level of gasoline and laundry, Saman's income needs to cover the increased cost of $1505.00 - $1005.00 = $500.00.

Therefore, Saman's income needs to increase by $500.00 for her to continue purchasing 100 gallons of gasoline and running 10 loads of laundry each month.

The points on the curve where the tangent line is horizontal or vertical for the equation r = cos(θ) are (1, 0) and (-1, 0) for horizontal tangents and (0, 6) and (0, -6) for vertical tangents.

To find the points on the curve where the tangent line is horizontal or vertical, we need to determine the values of θ that correspond to those points. For a horizontal tangent, the slope of the tangent line is zero. In the equation r = cos(θ), the value of r is constant, so the slope of the tangent line is determined by the derivative of cos(θ) with respect to θ. Taking the derivative, we get -sin(θ). Setting this equal to zero, we find that sin(θ) = 0, which occurs when θ is an integer multiple of π. Plugging these values back into the equation r = cos(θ), we get (1, 0) and (-1, 0) as the points on the curve with horizontal tangents.

For a vertical tangent, the slope of the tangent line is undefined, which occurs when the derivative of r with respect to θ is infinite. Taking the derivative of cos(θ) with respect to θ, we get -sin(θ). Setting this equal to infinity, we find that sin(θ) = ±1, which occurs when θ is an odd multiple of π/2. Plugging these values back into the equation r = cos(θ), we get (0, 6) and (0, -6) as the points on the curve with vertical tangents.

The standard deviation for a chi square distribution for given degree of freedom is 7.0711.

The chi-square distribution is parameterized by the number of degrees of freedom (df). As the number of degrees of freedom increases, the shape of the distribution becomes more symmetrical and approaches a normal distribution.

The standard deviation (σ) of a chi-square distribution with k degrees of freedom is given by the formula:

σ = sqrt(2k)

Therefore, for a chi-square distribution with 25 degrees of freedom:

σ = sqrt(2(25)) = sqrt(50) ≈ 7.0711
