Hence inverse of the function h is
h⁻¹ :x→ 2/(x-1) -1
Define inverse functionAn inverse function is a function that "undoes" the action of another function. In other words, if a function f(x) takes an input x and produces an output y, then its inverse function, denoted as f⁻¹(y) or sometimes as g(y), takes the output y and produces the input x such that f(x) = y.
Define functionA function is a rule that associates each element of a set (called the domain) with a unique element of another set (called the range or codomain).
Given function
f(x)=1+1/x for x>0
g(x)=(x+1)/2 for x>0
Given: h=fg
h=f(g(x))
h=1+1/(x+1)/2
Now, taking the inverse of the function h,
h=1+1/(x+1)/2
h-1=1/(x+1)/2
1/(h-1)=(x+1)/2
2/(h-1)=x+1
x=2/(h-1) -1
Hence inverse of the function h is
h⁻¹:x→ 2/(x-1) -1

The perimeter of the triangle is 28.08 units, the area of the triangle is 8.49 square units, and the height of the triangle is 3.18 units.
How are area and perimeter of a triangle calculated?The lengths of the triangle's sides must be determined using the distance formula in order to determine the triangle's perimeter:
Side X to Y length: [tex]\sqrt{(5-2)2 + (9-10)2}[/tex]]d(XY) equals sqrt[9+1] = sqrt (10)
Side Y to Z length: [tex]d(YZ) = \sqrt{[(1-9)2 + (6-5)2]} = \sqrt{65}[/tex]
Side Z to X length: [tex]\sqrt{(2-6)2 + (10-1)2]} = d(ZX) = \sqrt{16+81]} = \sqrt{97}[/tex]
Perimeter: (XY + YZ + d) (ZX)
Sqrt(10) + Sqrt(65) + Sqrt Equals the circumference (97)
Radius = 10.17 + 8.06 + 9.85
Diameter: 28.08
We can apply the following formula to determine the triangle's area:
(1/2) * Base * Height = Area
Every triangle side's length serves as the base. Using side YZ
sqrt = base (65)
We must drop a perpendicular from vertex X to side YZ in order to get the height. The height of the triangle equals the length of this perpendicular.
y - 9 = (1/5) is the equation of the line connecting points Y and Z. (x - 6)
y - 10 = (-5) is the equation for the line that is perpendicular to this line and passes through point X. (x - 2)
We may get the location of the perpendicular's intersection with side YZ by solving these two equations:
x = 3.08, y = 6.47
Hence, the distance between points X and the point of intersection on side YZ is the triangle's height:
height is equal to sqrt[(3.08-2)2 + (6.47-9)2] = sqrt[10.11] = 3.18.
Area = (1/2)*base*height*sqrt(65)*3.18 Area = (1/2)*base*height*area Area = 8.49

James and Kim are selling flower bulbs for a school fundraiser. Customers can buy packages of tulip bulbs and packages of crocus bulbs. James sold 3 packages of tulip bulbs and 7 packages of crocus bulbs for a total of $145. Kim sold 10 packages of tulip bulbs and 14 packages of crocus bulbs for a total of $334. Find the cost each of one package of tulips bulbs and one package of crocus bulbs.
Answers
The cost of one package of tulip bulbs is 11, and the cost of one package of crocus bulbs is 16.
To find the cost of one package of tulip bulbs and one package of crocus bulbs, follow these steps:
Write two equations based on the given information:
Equation 1 (James): 3T + 7C = 145
Equation 2 (Kim): 10T + 14C = 334
Solve the system of equations using the substitution or elimination method. In this case, we'll use the elimination
method by multiplying Equation 1 by 2 to make the coefficients of C the same:
Equation 1 modified: 6T + 14C = 290
Subtract Equation 2 from the modified Equation 1:
(6T + 14C) - (10T + 14C) = 290 - 334
-4T = -44
Divide both sides by -4 to find the value of T (tulip bulbs):
T = 11
Substitute the value of T back into Equation 1 to find the value of C (crocus bulbs):
3(11) + 7C = 145
33 + 7C = 145
Subtract 33 from both sides:
7C = 112
Divide both sides by 7 to find the value of C:
C = 16
So, the cost of one package of tulip bulbs is 11, and the cost of one package of crocus bulbs is 16.

Answers
the equation √x = -7 has no real solutions.
Why it is?
There is no real number x that satisfies the equation √x = -7.
The square root of a non-negative real number is always non-negative. Therefore, √x is non-negative for all real numbers x, including x = 0. However, -7 is negative, so the equation √x = -7 has no real solutions.

a fair coin is tossed until either a head comes up or four tails are obtained. what is the expected number of tosses?
Answers
The expected number of tosses until either a head comes up or four tails are obtained is 7/4
Let X be the random variable representing the number of tosses until either a head comes up or four tails are obtained.
Let's consider the first toss. There are two possible outcomes: heads or tails. If a head comes up on the first toss, then we stop and X = 1. If a tail comes up, we need to continue tossing until we get four tails in a row or a head.
Let Y be the random variable representing the number of additional tosses needed if the first toss is a tail. There are two possible outcomes for the second toss: heads or tails. If a head comes up, we stop and X = 2. If a tail comes up, we need to continue tossing until we get three tails in a row or a head.
Similarly, we can define Z as the random variable representing the number of additional tosses needed if the first two tosses are tails. There are two possible outcomes for the third toss: heads or tails. If a head comes up, we stop and X = 3. If a tail comes up, we need to continue tossing until we get two tails in a row or a head.
Finally, let W be the random variable representing the number of additional tosses needed if the first three tosses are tails. There are two possible outcomes for the fourth toss: heads or tails. If a head comes up, we stop and X = 4. If a tail comes up, we need to continue tossing until we get four tails in a row.
We can write X in terms of Y, Z, and W as follows
X = 1 + Y if the first toss is heads
X = 1 + 1 + Z if the first two tosses are tails and the third toss is heads
X = 1 + 1 + 1 + W if the first three tosses are tails and the fourth toss is heads
X = 1 + 1 + 1 + 1 if the first four tosses are tails
Now, we need to compute the expected values of Y, Z, and W.
If the first toss is a tail, the probability of getting another tail on the second toss is 1/2, and the probability of getting a head is also 1/2. Therefore,
E[Y] = 1/2(1) + 1/2(1 + Z)
If the first two tosses are tails, the probability of getting another tail on the third toss is 1/2, and the probability of getting a head is also 1/2. Therefore,
E[Z] = 1/2(1) + 1/2(1 + W)
If the first three tosses are tails, the probability of getting another tail on the fourth toss is 1/2, and the probability of getting a head is also 1/2. Therefore,
E[W] = 1/2(1) + 1/2(4)
Note that the expected value of W is 2, not 3, because if we get three tails in a row, we stop and X = 4.
Putting it all together, we have:
E[X] = 1/2(1) + 1/2(1 + E[Z])
= 1/2(1) + 1/2(1 + 1/2(1) + 1/2(1 + E[W]))
= 1/2(1) + 1/2(1 + 1/2(1) + 1/2(1 + 2))

Write the equation of a line that is perpendicular to the line y = 1/2x + 1 and goes through 6 on the x axis
Answers
Answer:
y = - 2x + 12
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{2}[/tex] x + 1 ← is in slope- intercept form
with slope m = [tex]\frac{1}{2}[/tex]
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{2} }[/tex] = - 2 , then
y = - 2x + c ← is the partial equation
to find c substitute (6, 0 ) , the point it crosses on the x- axis into the partial equation.
0 = - 2(6) + c = - 12 + c ( add 12 to both sides )
12 = c
y = - 2x + 12 ← equation of perpendicular line
GIVEN EQUATION IS y = 1/2x + 1
This method teach us in order to write this equation in perpendicular form we will change the coefficient of Y axis in to X axis and X axis into Y axis by a negative of sign WITH ONE of them and rePlace constant term as KNOW PERPENDICULAR EQUATION CAN BE WRITTEN AS
y = -2x + kSince the line passes through the point (6,0) on the x-axis, we can substitute these values into the equation to solve for k:
0 = -2(6) + k0 = -12 + kk = 12Therefore, the equation of the line that is perpendicular to y = 1/2x + 1 and passes through the point (6,0) is y = -2x + 12.Find the perimeter of a polygon. Assume that lines which appear to be tangent are tangent

One angle of a right triangle measures 85°. What is the measure of the other acute angle?
Answers
Answer:
5°
Step-by-step explanation:
The three angles of a triangle add up to 180° (every triangle, always) Since this triangle is a right triangle, one of the angles is a right angle, 90°.
Another angle is given, 85°.
x + 85° + 90° = 180°
x + 175° = 180°
x = 5°
To do this question using mental math, if one angle is 90° the other two angles must add up to 90° (thats the total of 180°) One angle is 85° then the other is 5°

Answers
Using the radians we know that the length of the arc in terms of π is s = 1.53 * π * 12 ft or s = 57.60 ft.
What is a circle?
All points in a plane that are at a specific distance from a specific point, the center, form a circle.
In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.
So, the central angle of degrees must first be converted to radians.
θ(rad) = 275/180 * π = 1.53 rad
Then, by multiplying the Central angle (in rad units) by the circle radius r, the arc length may be determined:
s = θ * r
Changing the θ and r values:
s = 1.53 * π * 12 ft
s = 57.60 ft

the pie chart shows the age distribution in a village of 120 people. how many villagers are over 60.And what percentage of villagers are under 25
Answers
We can say that approximately 48 villagers (40% of 120) are under the age of 25. This means that just under half of the population in this village is under the age of 25.
According to the pie chart, we can see that the village of 120 people has 20% of its population over the age of 60. To determine the exact number of villagers over 60, we can multiply the total population by the percentage of people over 60:
120 x 20% = 24
So there are 24 villagers over the age of 60 in this village.
As for the percentage of villagers under the age of 25, we can see from the pie chart that 40% of the population falls into this category. However, it is important to note that the question mentions a village of 120 people, while the percentage given in the chart may not reflect this exact number. Therefore, we cannot determine the exact number of villagers under the age of 25 without additional information.

Step-by-step explanation:
The remainder when f(x) is divided by x - 1 is 6.
Step-by-step Explanation:
To find the remainder when f(x) is divided by x - 1, we can use the remainder theorem, which states that the remainder of f(x) when divided by x - a is equal to f(a).
So, in this case, we need to evaluate f(1) to find the remainder when f(x) is divided by x - 1:
f(1) = 2(1)^3 + (1)^2 + 3
= 2 + 1 + 3
= 6
Therefore, the remainder when f(x) is divided by x - 1 is 6.

(hint: the formula for the volume of a cone is v
Answers
The height of the pile is increasing at a rate of approximately 0.056 feet per minute when the pile is 12 feet high.
We are given that sand is falling off at a rate of 14 cubic feet per minute, and the diameter of the base of the cone is approximately three times the altitude. Let h be the height of the pile at a given time t, then we can write the volume of the cone as V = (1/3)πr^2h, where r is the radius of the base of the cone. Since the diameter is three times the altitude, we have r = 3h/2.
Taking the derivative of the volume with respect to time, we get dV/dt = (1/3)π(9h^2/4)(dh/dt). Plugging in the given values, we get:
14 = (1/3)π(9h^2/4)(dh/dt)
Simplifying, we get:
dh/dt = 56/(3πh^2)
When the height of the pile is 12 feet, the rate of change of the height of the pile is:
dh/dt = 56/(3π(12)^2) ≈ 0.056 ft/min.
Therefore, the height of the pile is changing at a rate of approximately 0.056 ft/min when the pile is 12 feet high.

I run 10 laps around a track each day each lap is 400 meters how long would it take to run a total of 12 kilometers
Answers
Explanation;
First, let's calculate the total distance you run each day.
Distance per lap = 400 meters
Laps per day = 10
Total distance per day = Distance per lap × Laps per day
Total distance per day = 400 meters × 10 = 4,000 meters
Now we need to find out how many days it would take to run a total of 12 kilometers (12,000 meters).
Total distance desired = 12,000 meters
Number of days = Total distance desired / Total distance per day
Number of days = 12,000 meters / 4,000 meters
Number of days = 3
So, it would take you 3 days to run a total of 12 kilometers if you run 10 laps of 400 meters each day.
Answer:
It will take 3 days to runn total of 12 Kilometers
Step-by-step explanation:
12(1000) = 12,000 meters
400(10) = 4000 meters/day
12,000/4000 = 3 days

Answers
The false statement among the options is E. The power of a hypothesis test does depend on the sample size.
The power of a hypothesis test is indeed a measure of the test's ability to detect a difference between the estimated value and the true value of a parameter (Statement A). It represents the probability of correctly rejecting the null hypothesis when it is actually false.
Statement B is true as well. As the alpha level increases, the beta level of a hypothesis test decreases. Alpha (α) represents the probability of a Type I error (rejecting the null hypothesis when it is true), while beta (β) represents the probability of a Type II error (failing to reject the null hypothesis when it is false). Statement C is accurate, as beta is the measure of the probability of a Type II error, meaning the likelihood of failing to reject a false null hypothesis. Statement D is also true. The power of a hypothesis test increases as alpha increases because increasing the alpha level means that you are more likely to reject the null hypothesis when it is false, which ultimately increases the power of the test.
However, statement E is false. The power of a hypothesis test does depend on the sample size. As the sample size increases, the power of the test increases as well. Larger sample sizes provide more accurate estimates of the population parameters, which helps in better differentiating between the null and alternative hypotheses, leading to a higher power for the hypothesis test. Therefore, the correct option is E.

Jordan received $100 for a graduation present and deposited it in a savings account. Each week thereafter, he added $15 to the account but no interest was earned. Which equation represents the relationship between w, the number of weeks Jordan kept his money in the account, and t, the total amount in the savings account?
Answers
f(w) = 100 + 15t is the function that represents the relationship between w, the number of weeks Jordan kept his money in the account, and t, the total amount in the savings account
It is given to us that Jordan received $100 for a graduation present and deposited it in a savings account. Each week thereafter, he added $15 to the account but no interest was earned.
We need to write an equation represents the relationship between w, the number of weeks Jordan kept his money in the account, and t, the total amount in the savings account:
Graduation present = $100
Amount deposited per week = $15
Let, w be the number of weeks, and t, the total amount in the savings account, therefore, the function is:
f(w) = 100 + 15t
Therefore, f(w) = 100 + 15t represents the relationship between w, the number of weeks Jordan kept his money in the account, and t, the total amount in the savings account

Find the inverse function of y = 3x
Answers
Answer:
Step-by-step explanation:
To find the inverse of the function y = 3x, we need to swap the positions of x and y and then solve for y.
Step 1: Swap the positions of x and y
x = 3y
Step 2: Solve for y
Divide both sides by 3
x/3 = y
So the inverse function of y = 3x is x/3.
We can also verify that this is the inverse function by plugging in x/3 for y in the original equation and confirming that we get x:
y = 3x
x/3 = 3x/3
x/3 = x
Therefore, the inverse function of y = 3x is x/3.
Answer:
Step-by-step explanation:
The given function is y = 3x.
To find its inverse, we start by swapping x and y in the equation to get:
x = 3y
Next, we solve this equation for y to isolate it:
y = x/3
Therefore, the inverse of y = 3x is y = x/3.
There are 32 students in the school day. the ratio of girls to all the students in the play is 5:8.
Answers
Answer: 16 girls
Step-by-step explanation:
Step 1: Calculate the total number of students in the school by multiplying 32 by the ratio of girls to all the students, which is 5:8.
32 x (5/8) = 20
Step 2: Subtract the result from 32 to get the number of girls in the school.
32 - 20 = 12
Step 3: Multiply the result by the ratio of girls to all the students, which is 5:8.
12 x (5/8) = 16

The perimeter of a rectangular jewelry store is 186 feet. The store is 60 feet long. How wide is it?
Answers
Answer:
The width of the jewelry store is 33 feet.
Step-by-step explanation:
To solve the problem, we can use the formula for the perimeter of a rectangle, which is P = 2L + 2W where P is the perimeter, L is the length, and W is the width. Substituting the given values, we get 186 = 2(60) + 2W. Simplifying the right side, we get 186 = 120 + 2W. Subtracting 120 from both sides, we get 66 = 2W. Dividing both sides by 2, we get W = 33.
Therefore, the width of the jewelry store is 33 feet.
