The inverse of the function f(x) = 1/x is B. f⁻¹(x) = 1/x

The inverse of a function f(x) written as f⁻¹(x) is such that ff⁻¹(x) = f⁻¹f(x)

Given the function f(x) = 1/x,we desire to find its inverse. We proceed as follows.

Since f(x) = 1/x

Let f(x) = y

So,we have that

y = 1/x

Now, multiplying both sides by x,we have that

x × y = 1/x × x

xy = 1

Dividing though by y, we have that

xy/y = 1/y

x = 1/y

Now, relacing y with x and x with f⁻¹(x), the inverse of f(x), we have that

x = 1/y

x = 1

f⁻¹(x) = 1/x

So, the inverse is B. f⁻¹(x) = 1/x

The pythagorean theorem says a^2 + b^2 = c^2 when a and b are the sides of the right triangle and c is the hypotenuse (longest side, opposite the 90 degree angle).

so if  8^2 + 6^2 = 10^2, then it's a right triangle.

8^2 + 6^2 = 64 + 36 = 100 = 10^2, so yes, this is a right triangle.

a)The concentration will be 0.5 mg/L at approximately 1.18 hours.

c) [0, ∝) is a reasonable domain for this function.

d) The patient must receive the next intravenous dose of the drug between 0.75 and 1.35 hours after the initial dose.

e) The concentrations of the two drugs cannot be compared

A. To find when the concentration will be 0.5 mg/L, we can set the function equal to 0.5 and solve for t:

20t c(t)-20 2 +4 = 0.5

20t c(t)-20 2 = 3.5

20t c(t) = 2

3.5c(t) = 1.175

So the concentration will be 0.5 mg/L at approximately 1.18 hours.

B. Using the given formula, we can complete the table as follows:

| t    | c(t)         |

0    | 4            |

2    | 2.86        |

4    | 2.14         |

6    | 1.62         |

8    | 1.23         |

10   | 0.95         |

12   | 0.74         |

14   | 0.57         |

16   | 0.44         |

18   | 0.34         |

20   | 0.27        

C. Because time cannot be negative and the function has no imaginary values, the domain of the function is all non-negative real numbers.

As a result, [0,] is a reasonable domain for this function.

D. To maintain a concentration above 1 mg/L and below 8 mg/L, we need to solve the inequality:

1 < 20t

c(t)-20 2 +4 < 8

Simplifying this inequality, we get:

0.75 < t < 1.35

To maintain the desired concentration, the patient must receive the next intravenous dose of the drug between 0.75 and 1.35 hours after the initial dose.

E. Without additional information, we cannot compare the concentrations of the two drugs.

The information provided only allows us to analyze the intravenous drug concentration

Full Question:

The diagram shows the distance between my home, H, and two towns, A and B. It also shows information about journey times. See same attached.

Answer: 15cm?

Step-by-step explanation: I am doing this assignment right now, after i submit it i will reply with the answer. Edit: 15cm is correct.

The distance from point A (tangent point on clock) to point B (the hanger) is approximately 10 cm, based on the principles of right-angle triangles and Pythagorean theorem.

In this geometry problem, we're looking at a situation where a circular clock is hung by wires connected to a tangential point on the clock. By using right-angle triangle principles and the given radius of 15 cm from E to D, it''s key to recognize that triangle AED is a right triangle (since a radius perpendicular to a tangent at its point of contact forms a right angle).

So, the distance from A to E (the radius) is 15 cm. The distance from E to D is also a radius, hence is 15 cm as well. Now, by Pythagoras theorem for right triangle AED, the distance AD (the hypotenuse) is square root of (15^2 + 15^2), which is approximately 21.21 cm.

The distance BD from the top of the clock at point D to the hanger at point B is given as 10 cm. Since the clock is hanging from point B, this creates another right triangle ADB. The length from point A to B is found by subtracting BD (10 cm) from the hypotenuse AD (21.21 cm), which is roughly 11.21 cm. However, this option is not offered in the question, meaning a rounding must be made, so the answer is approximately 10 cm.

"The correct answer is: g(x), f(x), h(x)."To determine the correct order of the functions from least to greatest according to the average rate of change on the interval from x = 0 to x = 4, we need to calculate the average rate of change for each function.

The average rate of change is calculated by finding the difference in the function's values at the endpoints of the interval (x = 4 and x = 0) and dividing it by the difference in the corresponding x-values.

For function f(x), we have:

Average rate of change = (f(4) - f(0))/(4 - 0) = (64 - 0)/(4 - 0) = 64/4 = 16

For function g(x), since it is a linear graph, the average rate of change is constant throughout. Therefore, the average rate of change for g(x) is the same as the slope of the line, which is determined by the ratio of the change in y to the change in x. In this case, it would be the slope between the given x-intercept (-2) and y-intercept (-1), which is -1/2.

For function h(x), we need to find the average rate of change between x = 0 and x = 4. Substituting the values, we get:

Average rate of change = (h(4) - h(0))/(4 - 0) = (36 - 6)/(4 - 0) = 30/4 = 7.5

Now, let's compare the average rates of change for each function:

f(x): 16

g(x): -1/2

h(x): 7.5

From least to greatest, the correct order according to the average rate of change is:

To use the substitution method to solve the system, we need to solve one of the equations for x or y in terms of the other variable, and then substitute that expression into the other equation to get an equation in one variable that we can solve.

Let's solve the first equation for x in terms of y:

x + 4y = -9

x = -4y - 9

Now we substitute this expression for x into the second equation:

2x + 5y = -6

2(-4y - 9) + 5y = -6

Simplifying this expression, we get:

-8y - 18 + 5y = -6

-3y = 12

y = -4

Now we can substitute this value of y into either of the original equations to find x. Let's use the first equation:

x + 4y = -9

x + 4(-4) = -9

x - 16 = -9

x = 7

Therefore, the solution to the system is x = 7, y = -4.

Now let's look at the answer choices and see which one matches the equation we got by substituting x = -4y - 9 into the second equation:

A) 2(4-9)+ 5y-6 = -10 + 5y - 6 = 5y - 16

B) 21-4y-9)+5% -6 = -4y + 6

C) 2x+5(4-9)=-6 = 2x - 25 = -6

D) 2x+5(-4y-9)=-6 = 2x - 20y - 45 = -6

The answer choice that matches our equation is D), 2x + 5(-4y - 9) = -6.

The measure of the angle ∠S is 95°

Let's call angle Q as x. Then we can express the other angles in terms of x as follows:

Angle R = x + 25 (since angle R is 25° more than angle Q)

Angle S = x + 65 (since angle S is 65° more than angle Q)

We know that the sum of the angles in a triangle is always 180°, so we can write:

x + (x + 25) + (x + 65) = 180

Simplifying this equation, we get:

3x + 90 = 180

Subtracting 90 from both sides, we get:

3x = 90

Dividing both sides by 3, we get:

x = 30

Therefore, angle S is:

Step 1: Find a common denominator.

The denominators are 3y, 4, and 8. The least common multiple (LCM) of these is 24y.

Step 2: Adjust each term to have a denominator of 24y.

To do this, we multiply the numerator and denominator of each term by the appropriate factor:

For the term 8/3y, multiply numerator and denominator by 8: (8/3y) * (8/8) = 64/24y.

For the term 5y/4, multiply numerator and denominator by 6y: (5y/4) * (6y/6y) = 30y^2/24y.

For the term 5/8, multiply numerator and denominator by 3: (5/8) * (3/3) = 15/24y.

Step 3: Combine the terms.

Now that all terms have a common denominator of 24y, we can add them together:

(64/24y) + (30y^2/24y) - (15/24y)

Step 4: Combine the numerators.

Add the numerators of the fractions:

(64 + 30y^2 - 15) / 24y

Step 5: Simplify the numerator.

Combine like terms in the numerator:

(49 + 30y^2) / 24y

Thus, the simplified expression is (49 + 30y^2) / 24y, considering all permissible values of y.

The distance d between A and B is √(68), and the square of the distance in the y direction is 64.

To find the distance d between points A and B, we can use the distance formula:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Substituting the values of A and B, we get:
d = sqrt((4 - 2)^2 + (5 - (-3))^2)
d = sqrt(2^2 + 8^2)
d = sqrt(4 + 64)
d = sqrt(68)
Next, to calculate the square of the distance in the y direction, we need to find the difference between the y-coordinates of A and B and square it. So:
(y2 - y1)^2 = (5 - (-3))^2 = 8^2 = 64
Therefore, the square of the distance in the y direction is 64.
I'm here to help you with your question. To find the distance d between two points A(x1, y1) and B(x2, y2), we can use the distance formula:
d = √((x2-x1)² + (y2-y1)²)
Given the points A(2, -3) and B(4, 5), let's plug in the values:
d = √((4-2)² + (5-(-3))²)
Now, calculate the difference for each coordinate:
d = √((2)² + (8)²)
Next, square the differences:
d = √(4 + 64)
Finally, calculate the square root:
d = √(68)
ow, let's find the square of the distance in the y direction, which is (y2-y1)²:
(y2-y1)² = (5-(-3))²
Calculate the difference:
(y2-y1)² = (8)²
Square the difference:
(y2-y1)² = 64

The theoretical probability of exactly 4 students from your school being selected as contestants out of 10 possible contestant spots is approximately 0.009.

Assuming that each member of the audience has an equal chance of being selected as a contestant, the total number of possible ways to select 10 contestants from the audience is:

[tex]150 $ choose 10 = 150! / (10! \times (150 - 10)!) = 2,535,316,699,000[/tex]

To calculate the probability of exactly 4 students from your school being selected as contestants, we need to count the number of ways this can happen and divide it by the total number of possible outcomes.

There are 30 students from your school and 120 students from other schools in the audience.

We need to choose 4 students from your school and 6 students from other schools for the contestant spots.

The number of ways to do this is:

[tex]30 $ choose 4 \times 120 $ choose 6 = (30! / (4! \times 26!)) \times (120! / (6! \times 114!)) = 23,400,140,040,000[/tex]

Therefore, the probability of exactly 4 students from your school being selected as contestants is:

P(4 students selected) = (number of ways to select 4 students from your school and 6 students from other schools) / (total number of ways to select 10 contestants from the audience)

P(4 students selected) = 23,400,140,040,000 / 2,535,316,699,000.
