F(x)=x²-1/x+1
F'(x)= Lim h=0 (x+h) -f(x)/h
Answer:
So the derivative of the function F(x) = x^2 - 1/x + 1 is F'(x) = 2x - (x - 1)/x^2.
Step-by-step explanation:
The derivative of the function F(x) = x^2 - 1/x + 1 can be found by using the limit definition of the derivative. The derivative is the rate of change of the function at a given point and it is calculated as:
F'(x) = Lim h=0 (x + h)^2 - 1/(x + h) + 1 - (x^2 - 1/x + 1)/h
Expanding the expression inside the limit and simplifying, we get:
F'(x) = Lim h=0 2xh + h^2 - (1 - hx)/(x + h)^2
Using L'Hopital's Rule, we get:
F'(x) = Lim h=0 2x + 2h - (x - 1)/(x + h)^2
As h approaches 0, the limit becomes:
F'(x) = 2x + 2(0) - (x - 1)/x^2 = 2x - (x - 1)/x^2
So the derivative of the function F(x) = x^2 - 1/x + 1 is F'(x) = 2x - (x - 1)/x^2.

Find the distance between (1,0) and (9,15)\
The distance between the points is given by the equation D = 17 units
What is the distance between two points?Let the two points be A ( x₁ , y₁ ) and B ( x₂ , y₂ )
The distance from A to B is the same as the distance from B to A
Distance between two points is the length of the line segment that connects the two points in a plane.
The formula to find the distance between the two points is usually given by D = √( ( x₂ – x₁ )² + ( y₂ – y₁ )²)
This formula is used to find the distance between any two points on a coordinate plane or x-y plane
Given data ,
Let the distance between the points be D
Now , the equation will be
Let the first point be P ( 1 , 0 )
Let the second point be Q ( 9 , 15 )
Now , Distance between two points is the length of the line segment that connects the two points in a plane.
And , D = √( ( x₂ – x₁ )² + ( y₂ – y₁ )²)
D = √ ( ( 9 - 1 )² + ( 15 - 0 )² )
D = √ ( 8 )² + ( 15 )²
D = √ ( 64 + 225 )
D = √289

Newport High School has student elections every year. Lately, the school has seen a 10% decrease in voting from election to election. If 341 students voted this year, how many will be expected to vote 9 years from now? If necessary, round your answer to the nearest whole number.
Answer:
121 voters.
Step-by-step explanation:
To answer this question, we need to find the expected number of students who will vote 9 years from now. To do this, we will apply the 10% decrease in voting every year.
Starting with 341 students who voted this year, we decrease the number of voters by 10% every year.
After 9 years, the number of voters would be:
341 * (1 - 0.10)^9 = 341 * 0.354813389233575594 = 121.05
So, it is expected that 121 students will vote 9 years from now. Rounding to the nearest whole number, we get 121.
Therefore, the answer is 121 students.
There are 121 voters expected to vote 9 years from now.

Kweku would save $180 in a year buying electricity for the Desla electric compared to buying gas for the Deswagon, To make up for the higher sale price, it will take him more than 66 years.
What is subtraction?Subtraction is a mathematical operation. Which is used to remove terms or objects in the expression.
Given:
Deselectric costs $11900 more than the Deswagon.
Unit cost:
Deselectric: $0.11 per mile.
Deswagon: $0.12 per mile.

Am I a function? Asking for a friend
Answer: No.
Step-by-step explanation:
This is not a function because it fails the vertical line test.
What is the vertical line test?
The vertical line test is a test used to check if a graph is a function. If we place a vertical line on the graph, we should be able to shift it left and right without intersecting the graph in two places at once. Since this is a circle, it fails this test and is not a function.
\angle A∠A and \angle B∠B are vertical angles. If m\angle A=(8x-23)^{\circ}∠A=(8x−23) ∘ and m\angle B=(6x-5)^{\circ}∠B=(6x−5) ∘ , then find the measure of \angle A∠A.
Answer:
∠A = 49°
Step-by-step explanation:
Vertically opposite angles are congruent.
∠A = ∠B
8x - 23 = 6x - 5
Add 23 to both sides,
8x = 6x - 5 + 23
8x = 6x + 18
Subtract 6x from both sides,
8x - 6x = 18
2x = 18
Divide both sides by 2,
x = 18 ÷ 2
x = 9
∠A = 8x - 23
= 8*9 - 23
= 72 - 23
= 49°
what happens when the sampling distribution is altered (e.g. filtering out all values below the mean) and how does it effect type 1 errors.
In other words, altering the sampling distribution in this way increases the likelihood of making a type 1 error.
What is mean?The arithmetic mean, arithmetic average, or simply the mean or average, is the sum of a collection of numbers divided by the number of numbers in the collection in mathematics and statistics. The collection is frequently a collection of results from an experiment, observational research, or survey.
Here,
The sampling distribution is a distribution of the values of a statistic (such as the mean or median) calculated from a set of sample data. It gives us information about how the statistic is likely to vary from sample to sample, and it is used in hypothesis testing to calculate the probability of observing certain results if the null hypothesis is true.
Filtering out all values below the mean has the effect of changing the shape, location, and spread of the sampling distribution. For example, if the original sampling distribution is normally distributed with a mean of 0 and a standard deviation of 1, filtering out all values below the mean would result in a new sampling distribution with a mean greater than 0 and a standard deviation smaller than 1.
When the sampling distribution is altered, for example by filtering out all values below the mean, it can have an effect on type 1 errors. Type 1 errors occur when we reject the null hypothesis when it is actually true.

what is a1 in a geometric series for which Sn=21825, an=125, r=15.
The value of a1 in a geometric series for which Sn=21825, an=125, r=15 will be 5/9.
How to calculate fora termThe formula for the nth term in a geometric series is given by:
an = a1 * r^(n-1)
Where a1 is the first term, r is the common ratio, and n is the number of terms.
We are given Sn, an and r, and we can use the formula for the sum of a geometric series to solve for n:
Sn = a1 * (1 - r^n) / (1 - r)
Substituting the given values, we get:
21825 = a1 * (1 - 15^n) / (-14)
Multiplying both sides by -14, we get:
-304350 = a1 * (1 - 15^n)
Since we are given that an = 125, we can substitute this into the formula for an and solve for n:
125 = a1 * 15^(n-1)
Substituting a1 = -304350 / (1 - 15^n) from the equation above, we get:
125 = -304350 / (1 - 15^n) * 15^(n-1)
Dividing both sides by 15^(n-1), we get:
125 * 15^(1-n) = -304350 / (1 - 15^n)
Multiplying both sides by (1 - 15^n), we get:
125 * 15^(1-n) * (1 - 15^n) = -304350
Expanding the right-hand side, we get:
125 * (15 - 15^n) = -304350
Dividing both sides by 125, we get:
15 - 15^n = -2434.8
Adding 15^n to both sides, we get:
15^n = 15 - (-2434.8) = 2449.8
Taking the natural logarithm of both sides, we get:
n * log(15) = log(2449.8)
Dividing both sides by log(15), we get:
n = log(2449.8) / log(15)
Since n is the number of terms, it must be a positive integer. The closest positive integer to this value is 3, so n = 3.
Finally, we can use the formula for an to find a1:
an = a1 * r^(n-1)
Substituting the given values and n = 3, we get:
125 = a1 * 15^(3-1)
Dividing both sides by 15^(3-1), we get:
125 / 15^2 = a1
Calculating, we get:
a1 = 125 / 15^2
= 125 / 225

A company rents water tanks shaped like cylinders. Each tank has a radius of 4 feet and a height of 2 feet. The cost is 5 dollars per cubic foot. How much does it cost to rent one water tank? Use 3.14 for pi , and do not round your answer.
One water tank can be rented for 160 dollars, according to the provided statement.

The volume of the cylinder-shaped water tank is given by the formula
V = πr²h, where
r is the radius
h is the height.
Substituting the given values, we get:
