The domain of ( g o f o g ) ( x ), where "o" denotes composition of functions is ____.​

Answers

The domain of (g o f o g)(x),  where "o" denotes composition of functions is the set of all x in F such that f(x) is in the domain of g, and g(f(x)) is in the domain of g.

To determine the domain of the function (g o f o g)(x), we need to consider the domains of the functions g(x) and f(x), as well as the composition of these functions.

Let's assume that the domain of g(x) is G and the domain of f(x) is F.

Since (g o f o g)(x) means that we apply the function g to f(x), and then apply g to the result again, we need to ensure that the output of f(x) is a valid input for g(x).

Therefore, the domain of (g o f o g)(x) is the set of all values of x in F such that g(f(x)) is in G, and g(y) is in G for all y in the range of g(f(x)).

In other words, the domain of (g o f o g)(x) is the set of all x in F such that f(x) is in the domain of g, and g(f(x)) is in the domain of g.

Thus, the domain of (g o f o g)(x) is the set of all x in F such that f(x) is in the domain of g, and g(f(x)) is in the domain of g.

if you increase your reading speed so that each page takes you 30 seconds less than it did before, and you begin reading 20 minutes per day, how many 200 page books can you now read in a year

Answers

We can read 91 books in a year if you increase your reading speed so that each page takes you 30 seconds less than it did before.

How is the number of books calculated?

Now If each page now takes 30 seconds less to read than before,

then you will save 30*200 = 6000 seconds (or 100 minutes) on each book.

So, the time it will take you to read a 200-page book will be

20 minutes - 100 minutes = -80 minutes,

which means you will finish a 200-page book in 80 minutes (or 1 hour and 20 minutes).

In a year, there are 365 days. If you read for 20 minutes per day, then you will read for a total of

365 * 20 = 7300 minutes (or 121.67 hours) in a year.

Since you can finish a 200-page book in 80 minutes, you can read 7300/80 = 91.25 books in a year.

However, since you cannot read a fraction of a book, the maximum number of 200-page books you can read in a year is 91 books.

If the minimum perimeter of a quadrilateral is 200cm, what is the maximum area of the quadrilateral
guesses will be reported
first correct answer gets brainliest <3

Answers

The maximum area of the quadrilateral is achieved when it is a square with a side length of 50cm, resulting in an area of 2500cm².

This is because a square has equal sides and equal angles,

resulting in the most efficient use of the perimeter to enclose the maximum area.

To see why, consider a rectangle with a perimeter of 200cm.

If the rectangle is long and thin, with one side much longer than the others,

then it will have a smaller area than a square with the same perimeter.

This is because the longer sides of the rectangle will be less effective at enclosing area than the shorter sides.

Hence, The maximum area of a quadrilateral with a minimum perimeter of 200cm is achieved when the quadrilateral is a square.

After an antibiotic is taken, the concentration of the antibiotic in the bloodstream is modeled by the function C(t) = 4te-397, where t is measured in hours and C is measured in ag Use the closed interval methods to mg detremine the maximum concentration of the antibiotic between hours 1 and 7. Write a setence stating your result, round answer to two decimal places, and include units.

Answers

To find the maximum concentration of an antibiotic between hours 1 and 7, first find the critical points of the function C(t), then evaluate C(t) at the critical points and endpoints to choose the highest value.

To determine the maximum concentration of the antibiotic between hours 1 and 7, follow these steps:
1. Find the critical points of the function C(t) = 4te^(-397). To do this, find the first derivative of the function, C'(t), and set it equal to 0.
2. Check the value of C(t) at the critical points and the endpoints of the interval, t=1 and t=7.
3. Choose the highest value of C(t) among the critical points and the endpoints.
1: Find the first derivative, C'(t).
C(t) = 4te^(-397)
C'(t) = 4e^(-397)(1-397t)
2: Set the first derivative equal to 0 and solve for t.
4e^(-397)(1-397t) = 0
1 - 397t = 0
t = 1/397
3: Evaluate C(t) at the critical point t = 1/397 and the interval endpoints t = 1 and t = 7.
C(1/397) = 4(1/397)e^(-397(1/397)) ≈ 0.01 ag/mg
C(1) = 4(1)e^(-397(1)) ≈ 0.00 ag/mg
C(7) = 4(7)e^(-397(7)) ≈ 0.00 ag/mg
The maximum concentration of the antibiotic occurs at t = 1/397 hours, with a concentration of approximately 0.01 ag/mg. What is Titration: Titration is a technique by which we know the concentration of unknown solution using titration of this solution with solution whose concentration is known.

Find the following derivative:

Answers

The derivative of the given function with respect to x is:
f'(x) = e^(x^2 + 1) * (1 + 2x^2)

To find the derivative of the given function. Let's first rewrite the function for clarity: f(x) = x * e^(x^2 + 1).

To find the derivative f'(x) with respect to x, we'll apply the product rule since we have a product of two functions: x and e^(x^2 + 1). The product rule states that if you have a function f(x) = g(x) * h(x), then f'(x) = g'(x) * h(x) + g(x) * h'(x).

In this case, g(x) = x and h(x) = e^(x^2 + 1). First, let's find the derivatives g'(x) and h'(x):

g'(x) = d/dx (x) = 1
h'(x) = d/dx (e^(x^2 + 1)) = e^(x^2 + 1) * d/dx (x^2 + 1) = e^(x^2 + 1) * (2x)

Now, we can apply the product rule:



f'(x) = g'(x) * h(x) + g(x) * h'(x) = 1 * e^(x^2 + 1) + x * (e^(x^2 + 1) * 2x)

Simplifying the expression, we get:

Given ⊙E with diameter AC, m∠CED=(3x)°, (m∠BEC=3x+2)°, and m∠AEB=(6x+7)°. Find x and mBD⌢

Answers

The following is the value of x and mBD: x = 83/6 and mBD⌢ = 83°.

Given circle E (⊙E) with diameter AC, we have the following information:

1. m∠CED = (3x)°
2. m∠BEC = (3x + 2)°
3. m∠AEB = (6x + 7)°

Since AC is the diameter of the circle, the inscribed angle ∠AEB is subtended by the diameter and thus forms a semicircle. In a semicircle, the inscribed angle is always a right angle. Therefore, m∠AEB = 90°. We can now set up the equation:

(6x + 7)° = 90°

Solving for x:
6x = 83
x = 83/6

Now, we need to find the measure of arc BD (mBD⌢). We can do this by finding the measure of angle BEC, as the measure of an inscribed angle is half the measure of its intercepted arc.

m∠BEC = (3x + 2)° = (3(83/6) + 2)° = (83/2)°

Since the measure of an inscribed angle is half the measure of its intercepted arc:

mBD⌢ = 2(m∠BEC) = 2(83/2)° = 83°

So, x = 83/6 and mBD⌢ = 83°.

Answer this following question
y = sin x + cos x / csc x

Answers

The expression equation y = sin x + cos x / csc x can be simplified to y = cos x sin^2 x + cos^2 x.

To simplify the expression, we can first replace csc x with 1/sin x. This gives us y = sin x cos x + cos^2 x / sin x.

Next, we can factor out cos x from the numerator of the second term to get y = cos x (sin x + cos x) / sin x.

Using the identity sin^2 x + cos^2 x = 1, we can replace sin^2 x with 1 - cos^2 x in the numerator of the first term. This gives us y = cos x (1 - cos^2 x) / sin x + cos x (sin x + cos x) / sin x.

Simplifying the expression further, we get y = cos x (1 - cos^2 x + sin x + cos x) / sin x.

Finally, we can combine the terms in the numerator to get y = cos x (sin^2 x + 2cos x sin x + 1) / sin x.

Using the identity sin^2 x = 1 - cos^2 x, we get y = cos x (3cos^2 x + 2cos x) / sin x.

Simplifying the expression, we arrive at y = cos x (cos x + 2) (3cos x + 2) / sin x.

Therefore, the simplified expression is y = cos x sin^2 x + cos^2 x, which can also be written as y = cos x (sin x)^2 + cos^2 x.

Ms. Yamagata needs to buy at least 2628 6-inch tiles to cover the floor of her rectangular bathroom.

To determine the least number of 6-inch tiles Ms. Yamagata needs to buy to cover her 9 feet long and 73 feet wide bathroom floor, follow these steps:

1. Convert the dimensions of the bathroom to inches, as the tiles are measured in inches:
  9 feet * 12 inches/foot = 108 inches long
  73 feet * 12 inches/foot = 876 inches wide

2. Determine the total area of the bathroom in square inches:
  Area = length * width = 108 inches * 876 inches = 94,608 square inches

3. Calculate the area of a single 6-inch tile:
  Area = length * width = 6 inches * 6 inches = 36 square inches

4. Divide the total area of the bathroom by the area of a single tile to find the least number of tiles needed:
  Number of tiles = total area / tile area = 94,608 square inches / 36 square inches ≈ 2,628.56

The lengths of the sides of a triangle


are 9, 12, and 15. what is the perimeter


of the triangle formed by joining the


midpoints of these sides?

Answers

The perimeter of the triangle formed by joining the midpoints of the sides of the original triangle is 3.

To find the perimeter of the triangle formed by joining the midpoints of the sides of the original triangle, we first need to find the midpoints. The midpoint of a side of a triangle is the point that is exactly halfway between the endpoints of that side.

Using the formula for the midpoint of a line segment ((x1+x2)/2, (y1+y2)/2), we can find the midpoints of the sides with lengths 9, 12, and 15:

Midpoint of the side with length 9: ((9+12)/2, (0+0)/2) = (10.5, 0)

Midpoint of the side with length 12: ((9+15)/2, (0+0)/2) = (12, 0)

Midpoint of the side with length 15: ((12+9)/2, (0+0)/2) = (10.5, 0)

Note that all three midpoints lie on the x-axis.

Now we can find the lengths of the sides of the triangle formed by joining the midpoints. These sides are the line segments connecting the midpoints, and their lengths are equal to the distances between the midpoints:

Length of the side connecting (10.5, 0) and (12, 0):

d = sqrt((12-10.5)^2 + (0-0)^2) = 1.5

Length of the side connecting (10.5, 0) and (10.5, 0):

d = sqrt((10.5-10.5)^2 + (0-0)^2) = 0

Length of the side connecting (12, 0) and (10.5, 0):

d = sqrt((10.5-12)^2 + (0-0)^2) = 1.5

So the triangle formed by joining the midpoints of the sides of the original triangle is an isosceles triangle with two sides of length 1.5 and one side of length 0. The perimeter of this triangle is:

Perimeter = 1.5 + 1.5 + 0 = 3

A person uses a screwdriver to turn a screw and insert it into a piece of wood. The person applies a force of 20 newtons to the screwdriver and turns the handle of the screwdriver a total distance of 0. 5 meter. How would these numbers be different with a hammer and a nail instead of a screwdriver and a screw

Answers

Using a hammer and nail instead of a screwdriver and screw would change the type of force applied (linear versus rotational) and the distance covered (shorter linear distance versus longer turning distance). These differences can affect the efficiency, holding power, and ease of use when connecting materials.

When using a screwdriver and screw, the applied force of 20 newtons and turning distance of 0.5 meters involve rotational motion to insert the screw into the wood. The screwdriver acts as a lever, and the screw's threads translate the rotational force into linear motion, increasing the grip strength and holding power.

In contrast, when using a hammer and nail, the force applied would be different because the action is linear instead of rotational. The hammer delivers a series of high-impact, short-duration forces to drive the nail into the wood. The amount of force required would depend on factors like the size of the nail, the hardness of the wood, and the user's strength.

Additionally, the distance covered during hammering would be different. Unlike the screwdriver's 0.5-meter turning distance, the hammer's motion covers a shorter linear distance as it strikes the nail head repeatedly. The total distance depends on the number of hammer strikes and the length of the nail.

A ferry is used to transport guests from the dock to two hotels across a large lake. The hotels are located 550 m apart. The first hotel is at a 49 angle between the dock and the second hotel. The second hotel is at a 56 angle between the dock and the first hotel. How far is each hotel from the dock?

Answers

The first hotel is approximately 0.6246 meters away from the dock, and the second hotel is approximately 0.4931 meters away from the dock.

To solve this problem, we can use trigonometry and create a system of equations based on the given angles and distances. Let's assume the distance between the dock and the first hotel is x meters and the distance between the dock and the second hotel is y meters.

Using the law of sines, we can relate the angles and distances:

For the first hotel:

sin(49°) = y / x     ...(Equation 1)

For the second hotel:

sin(56°) = x / y     ...(Equation 2)

We can rearrange Equation 1 to solve for y:

y = x * sin(49°)

Substituting this value of y into Equation 2:

sin(56°) = x / (x * sin(49°))

sin(56°) = 1 / sin(49°)

Now, we can solve for x by isolating it:

x = sin(56°) * sin(49°)

Plugging in the values and evaluating the equation:

x = 0.8290 * 0.7539

x ≈ 0.6246

Therefore, the distance between the dock and the first hotel (x) is approximately 0.6246 meters.

To find the distance between the dock and the second hotel (y), we can substitute this value back into Equation 1:

y = 0.6246 * sin(49°)

y ≈ 0.4931

Hence, the distance between the dock and the second hotel (y) is approximately 0.4931 meters.

In summary, the first hotel is approximately 0.6246 meters away from the dock, and the second hotel is approximately 0.4931 meters away from the dock.

Let the region r be the area enclosed by the function f(x)=x^2+1 and g(x)=2x+1. if the region r is the base of a solid such that each cross section perpendicular to the x axis is a square, find the volume of the solid.

Answers

The volume of the solid is 32/15 cubic units.

How to find volume of the solid?

To find the volume of the solid, we need to integrate the area of each square cross section perpendicular to the x-axis over the interval [a, b], where a and b are the x-coordinates of the intersection points of f(x) and g(x):

First, we find the intersection points of the two functions:

x²+1 = 2x+1

x² - 2x = 0

x(x-2) = 0

x = 0 or x = 2

So, a = 0 and b = 2.

Next, we find the side length of each square cross section. Since the cross section is a square, the side length is equal to the difference between the y-coordinates of the functions f(x) and g(x) at each x:

Side length = f(x) - g(x) = (x²+1) - (2x+1) = x² - 2x

Finally, we integrate the area of each square cross section over the interval [0, 2] to get the volume of the solid:

V = ∫[0,2] (x² - 2x)² dx

V = ∫[0,2] (x⁴- 4x³ + 4x²) dx

V = [1/5 x⁵ - 1 x⁴ + 4/3 x³] [0,2]

V = (1/5 x⁵ - 1 x⁴ + 4/3 x³)|[0,2]

V = (1/5(2⁵) - 1(2⁴) + 4/3(2³)) - (1/5(0⁵) - 1(0⁴) + 4/3(0³))

V = (32/5 - 16/3)

V = 32/15

Therefore, the volume of the solid is 32/15 cubic units.

Find the area of the regular polygon with the given apothem a and side length s.


pentagon, a = 10. 4 cm, s = 15. 1 cm

Answers

The area of the regular pentagon is approximately 392.2 square centimeters.

The area of a regular polygon can be calculated using the formula:

A = (1/2) * apothem * perimeter

where perimeter = number of sides * side length.

For a pentagon with side length s = 15.1 cm, the perimeter is:

perimeter = 5 * 15.1 = 75.5 cm

The apothem is a = 10.4 cm.

Using the formula, we get:

A = (1/2) * 10.4 * 75.5

A = 392.2 cm^2

Therefore, the area of the regular pentagon is approximately 392.2 square centimeters.

The results of the chi-square test of independence found that fear of crime depended on one's perception of whether their neighborhood was a high crime area or not. if the null hypothesis is rejected, which is the most appropriate conclusion that can be made

Answers

The most appropriate conclusion that can be made when the null hypothesis is rejected for the chi-square test of independence is: There is a significant association between fear of crime and one's perception of their neighborhood as a high crime area or not.

If the null hypothesis is rejected in a chi-square test of independence, it means that there is a significant association between the two variables being studied. In this case, the fear of crime is dependent on one's perception of whether their neighborhood is a high crime area or not.

Therefore, the most appropriate conclusion that can be made is that there is a significant relationship between the two variables, and one's perception of their neighborhood being a high crime area or not is a predictor of fear of crime. However, the chi-square test of independence does not determine causality, so it is not possible to conclude which variable is causing the other. Further research would be required to determine the direction and nature of the relationship between the two variables.
