Find a power series representation for the function; find the interval of convergence. (Give your power series representation centered at x = 0.)
f(x)= 1/(1-9x)
sum from n=0 to infinity [?] provided |x| < [?]
The power series representation for the given function is:
1+ 9x + (9x)² + (9x)³ + .... (9x)ⁿ (where 0 ≤ n ≤ ∞).
What is the power series?
Power series is a sum of terms of the general form aₙ(x-a)ⁿ. Whether the series converges or diverges, and the value it converges to, depends on the chosen x-value, which makes power series a function.
Let u = 9x.
Return to the series above and replace each u with a 9x directly:
Where 0 n , 1 + 9x + (9x) 2 + (9x) 3 +.... (9x) n
Here, the interval of convergence is easily found. It follows that
|9x| 1 -1/9 x 1/9 because we know that geometric series must have | u | = 1
Finally, we may leverage the fact that geometric series have a sum to get the sum: S = a / (1 - u).
Here, u = 9x and a = 1
Therefore, the total is simply S = 1 /(1 - 9x).
Any sum can be calculated provided x is between -1/9 and x and less than 1/9.

A line passes through the point (-4,8) and has a slope of -6 .
Write an equation in slope-intercept form for this line.
Answer:
y = (-6)*x - 16
Step-by-step explanation:
The slope-intercept form of a line is given by the equation:
y = mx + b
where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis).
In this case, the line passes through the point (-4,8) and has a slope of -6, so we can plug these values into the equation to find the y-intercept:
y = (-6)*x + b
We know that the line passes through the point (-4,8), so we can substitute these values into the equation to solve for b:
8 = (-6)*(-4) + b
8 = 24 + b
b = -16
Therefore, the equation of the line in slope-intercept form is:
y = (-6)*x - 16

Write a real-world problem that can be represented by the algebraic equation shown.
6x + 5 = 77
Answer:
One real-world problem that can be represented by the algebraic equation 6x + 5 = 77 is determining the number of items that must be sold at a certain price in order to reach a target profit. For example, suppose a business owner wants to make a profit of $77 by selling items for $6 each. The algebraic equation 6x + 5 = 77 can be used to determine the number of items that must be sold in order to reach this profit. In this case, x represents the number of items that must be sold, and the solution to the equation (x = 11) indicates that the business owner must sell 11 items in order to make a profit of $77.
Assume the random variable X is normally distributed with mean μ = 50 and standard deviation σ= 7, Compute the probability. Be sure to draw a normal curve with the area corresponding to the probability shaded. P(X> 37) Click the icon to view a table of areas under the normal curve. Which of the following normal curves corresponds to P(X> 37)? OA. OC. 37 50 37 50 37 50 PX-37)-□ (Round to four decimal places as needed.)
The normal curve that corresponds to P (X > 37) is C, as the shaded area corresponds to the probability of 0.4207.
The normal curve is a bell-shaped curve which is used to represent a continuous probability distribution. It is used to represent the probability of a random variable X, which is normally distributed with mean μ and standard deviation σ. In this case, we have X with mean μ = 50 and standard deviation σ = 7. To compute the probability P(X > 37), we first draw a normal curve with the area corresponding to the probability shaded. Then, we can look up the area from the table of areas under the normal curve. The area corresponds to 0.4207, and the normal curve that corresponds to this probability is C, as the shaded area corresponds to the probability of 0.4207. This normal curve has the mean of 50 and the standard deviation of 7, with the area beyond 37 shaded.

C. c = 0.3p +3.5
D. c = 0.9p + 3.5
If a customer buys 2 cantaloupes and p pounds of potatoes on friday from the local farmers' market, the total cost equation would be A. C = 0.63p + 7.
Equation is a mathematical statement that is made up of two expressions connected by an equal sign. Equation also often contain an algebra. Algebra is used in maths when you do not know the exact number in a calculation.
Based from the question above, we don't know the exact number of potato that the customer bought. We only know that the customer buys p pounds of potatoes.
Potato price = $0.90
on Friday, the potato price is (30% discount)
= 0.90 - (0.90 * 30%)
= $0.63
Since the customer buys for p pounds of potatoes, therefore the total cost of potatoes
= $0.63 * p
= 0.63p
From the question above, we know that the customer buys 2 cantaloupes.
cantaloupes price = $3.50 each
The total cost for cantaloupes
= 2 * $3.50
= $7

Let R = [0,6] [0, 6]. Subdivide each side of R into m =n = 3 subintervals and use the Midpoint Rule to estimate the value f JI.(v 22) dA.
2f(3,1)
To use the midpoint rule to estimate the value of the double integral of a function f(x,y) over the region R=[0,6]x[0,6], we need to divide the region R into a grid of subintervals, with m subintervals in the x-direction and n subintervals in the y-direction. In this case, m=n=3, so we divide each side of the region R into 3 subintervals of equal length.
The midpoint rule states that the approximation of the integral is given by the sum of the areas of the rectangles formed by the subintervals, where the height of each rectangle is given by the value of the function at the midpoint of the subinterval.
To implement the midpoint rule, we first need to determine the width and height of each subinterval. The width of the subintervals in the x-direction is given by (6-0)÷3 = 2, and the width of the subintervals in the y-direction is also given by 2. The height of each rectangle is given by the value of the function f at the midpoint of the subinterval.
We can then evaluate the double integral by summing the areas of the rectangles formed by the subintervals. For example, the first rectangle would have a height equal to the value of the function at (0+2)÷2=1 and a width of 2, so its area would be 2f(1,1). The second rectangle would have a height equal to the value of the function at (2+4)÷2=3 and a width of 2, so its area would be 2f(3,1)

Given, two buses are driving along parallel freeways that are 12 miles apart, one heading east and the other heading west.
Assuming that each bus drives a constant 58 mph.
Now, we have to find the rate at which the distance between the buses is changing when they are 13 miles apart and heading towards each other.
Considering distance as a function of time,
D = f(t) = √((12)² + (13 - 116t)²)
f'(t) = (13 - 116t)(-116)/√((12)² + (13 - 116t)²)
f'(0) = (13 - 116(0))(-116)/√((12)² + (13 - 116(0))²)
f'(0) = -1508/√(144 + 169)

The airflow's propensity to stick to the ball's surface is the Coandă effect in this situation. This indicates that the streamlines are curved at the ball's surface, with a radius of curvature roughly equal to the ball's radius. This curvature produces a pressure gradient, much like it does in the theory of lift, which I assume to be constant over the surface:

Carlos paid a total of $64 to rent a car.
The rental company charges a one-time fee of $20, with an additional charge of $0.50
per mile driven.
How many miles did Carlos drive the rental car?
Use the drop-down menus to complete the sentences below.
The number of miles Carlos drove the rental car is 88 miles.
How to find the number of miles Carlos drove?Carlos paid a total of $64 to rent a car. The rental company charges a one-time fee of $20, with an additional charge of $0.50 per mile driven.
Therefore, the number of miles Carlos drive the rental car can be calculated as follows:
Using equation,
let
x = number of miles driven
64 = 20 + 0.50x
subtract 20 from both sides of the equation'
64 - 20 = 20 - 20 + 0.50x
44 = 0.50x
divide both sides by 0.50
Therefore,
44 / 0.50 = 0.50x / 0.50
x = 88
Therefore, the number of miles is 88 miles.

we have a room full of n people. any given pair of people are either friends or strangers. in this room, alex is considered the most popular because he has k friends, and no other person in the room has more than k friends. prove that we can find a group with at least n k 1 people such that no two members of the group are friends.
a group with at least n k 1 people such that no two members of the group are friends,We will prove this statement by inductive hypothesis.
Base Case: If n=k+1, then we can easily find a group with nk1 people such that no two members of the group are friends. We simply select the k+1 people in the room, excluding Alex. Since Alex has k friends, and no other person in the room has more than k friends, it follows that none of these k+1 people are friends.
Inductive Step: Assume that the statement is true for n=k+1. Now we must show that it is true for n=k+2.
We can select a group of k+1 people from the room, again excluding Alex. By the inductive hypothesis, we know that no two members of this group are friends. Now, we select the remaining person in the room, and add them to the group. This person cannot be friends with any of the members of the group, since Alex has k friends and no other person in the room has more than k friends. Therefore, the group we have formed has at least nk1 people, and no two members of the group are friends.
Therefore, by induction, we have proved that we can find a group with at least nk1 people such that no two members of the group are friends.

The value of x is $53.34 but cannot exceed $115, while the value of y can be as low as $160 but cannot exceed $345.
What is an inequality?Relationships that compare two numbers or other mathematical expressions in an unequal manner are known in mathematics as inequalities. The most common use is to compare the magnitude of two numbers on a number line.
The answer to the query is
Diane will make a charitable donation "up to $460," which indicates it can be less than or equal to 460 but not more. Then,
$460 donated to charity (max)
plus $160 for educational (160 being the minimum)
Education is also stated to be three times (or greater) than City.
If x represents the city and y represents education, then
x + y = 460 . And we are aware that y 3x.
x + 3x = 4x = 460
x = 115.
This implies that she will contribute $345 to Educational when she donates 3 times (or $115) to City. The maximum value is these.
She won't provide more than $460.
Earlier, Educational had a minimal need.
When y = 160,
x equals y/3,
=> x = 160/3 = $53.34. She so gave 213.34 dollars, which is still less than $460.
As a result, x (which is City) might be anywhere between $53.34 and $115.
x, which stands for educational, might be as little as $160 or as high as $345.
