Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified line. Sketch the region, the solid, and a typical disk or washer.
y = x5, y =
square root of x
; about the x-axis
Rotating the area bounded by the given curves around the designated line yields the solid's volume as [tex]V = \frac{9}{22}\pi[/tex]
The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere. Different forms have various volumes.
The amount
of space that a solid occupies is measured by its volume. The amount of unit cubes required to completely fill the solid serves as the measurement. The capacity of an object to hold matter is generally thought of as its volume in three dimensions.
The functions provided are,
[tex]`y = f(x) = \sqrt{x}``y = g(x) = x^5`[/tex]
By rotating the area around the x-axis, the solid's volume is given by (using washer method)
[tex]V = \pi int_a^b [f^2(x)-g^2(x)]dx[/tex]
evaluate the integral, limit the plugins, and
[tex]V = \pi int_0^1 [(\sqrt{x})^2-(x^5)^2]dx\\\\V= \pi int_0^1 [x-x^10]dx V = \pi [\frac{x^2}{2}-\frac{x^11}{11}]_0^1 V = \pi [\frac{1^2}{2}-\frac{1^11}{11}]. V = \pi [\frac{1}{2}-\frac{1}{11}] = \frac{9}{22}\pi[/tex]

Find the value of Za:
Z 0.47=
Round to 2 decimals
The value of za is 80.47.
What is value?Value is the regard that something is held to deserve,the important, worth or usefullness of something.
let us find the value of zero Alpha, Given that alpha is .32. So the value of Z the it is 0.32. Well, we need to begin to considering that we need to the find actually the differentiate one minus alpha. Thus it is going to be in this case one of the (-) 10.32. This is going to be the 0.68. So actually Z of .32, we're going to need to find 0.68 inside the Z table. So let's look at it at it. Look at that at 0.68 oh eight.Let give us the Z score of 80.47. So we can tell that the Z score of zero of alpha, given that the Alpha is 00.32 is going to be 0.47.

Suppose that balloon owners get to pay lower costs for insurance next year. How would this affect the demand curve for balloon rides? How would this affect the supply curve for balloon rides?
A balloon payment is a one-time, large-scale principal payment made near the end of the loan term.
What impact would this have on the demand curve for hot air balloon rides?Total revenue is the amount of money made from the sale of a specific number of items at a specific price.A demand curve is a graph that shows the amounts of stores consumers want at different prices and contains the demand for that product on the y-axis and the price on the x-axis.If a product's price decreases, consumers are more likely to choose it over alternatives that are suddenly more expensive or to simply purchase more quantities of the product, which raises demand from customers.In a similar vein, demand will decline if price rises, all else being equal.To learn more about demand curve demonstrate refer to:

Step-by-step explanation:
If you are looking for the total amount spent, first we will convert 2 3/4 into a decimal, which is 2.75. 2.75 X 19.50 = 53.625. She bought 53.525 dollars worth of blue paint, now we solve for orange. 1 1/3 X 16 = 64/3, which is simplified to 21 1/3. If we add the two togetherwe get 74.9583, but the 3 is repeated.

b. When will the population of the state reach 28.3 million?
a. In 2000 , the population of the state was ? million.
The population of the city in 2000 = 23.1 million
In 2006 the population will be equal to 28.3 million
Applications of Compound interest:Compound interest may be used in a variety of situations, including increasing or decreasing population, Increasing the count of bacteria increasing an item's value, and a decrease in an item's worth.
The formula for Compound interest is given by
A = Pe^rtWhere P = Principal amount or Initial value
r = rate of interest or increase
t = time period
Here we have
The formula [tex]A = 23.1 e^{(0.0152t)}[/tex] represents the population of a US state, A, in millions, 't' years after 2000.
Here we need to solve the following questions
a. What was the population of the state in 2000
Compare the given formula with A = Pe^rt
=> [tex]23.1 e^{0.0152t} = Pe^{rt}[/tex]
=> Initial value or initial population, P = 23.1 and
rate of increase r = 0.0152
Therefore,
The population of the city in 2000 = 23.1 million
b. When will the population of the state reach 28.3 million?
As we know in 2002 the population = 23.1 million
Let's assume that after 'n' year the population will become 28.3 million
As we know Rate of increase = 0.0152
From the given formula
Population of the city after n, A = 23.1 e^(0.0152n)
As we assumed the population after n years = 28.3
=> 23.1 e^(0.0152n) = 28.3
=> e^(0.0152n) = 28.3/23.1
=> e^(0.0152n) = 1.225
Apply log on both sides
=> log e^(0.0152n) = log 1.225
=> 0.0152n log e = log 1.225
=> 0.0152n (1) = 0.0881
=> n = 0.0881/0.0152
=> n = 5.8 ≅ 6
After 6 years the population will be 28.3 million
After 6 years i.e 2000 + 6 = 2006
Therefore,
In 2006 the population will be equal to 28.3 million

The number of acres owned for which the average intake is 2200 calories per day is 2 acres obtained by the algebraic expression that relates the acres of land and the calories per day.
What is an algebraic expression?An algebraic expression is formed by variables, constants, and arithmetic operations. An algebraic expression provides the relation between the input and output variables i.e., x and f(x) respectively.Calculation:It is given that, the number of calories consumed daily by a person owing x acres of land is given by the algebraic expression,
C(x) = 270 ln(x+1) + 1900
The average intake of calories consumed per day is given by C(x) = 2200
Here x is the number of acres of land. Then, the required number of acres of land is
C(x) = 270 ln(x+1) + 1900
⇒ 2200 = 270 ln(x+1) + 1900
⇒ 270 ln(x+1) = 2200 - 1900
⇒ 270 ln(x+1) = 300
⇒ ln(x+1) = 300/270 = 10/9
Applying base 'e' on both sides, we get
⇒ (x+1) = [tex]e^\frac{10}{9}[/tex]
⇒ x+1 = 3.0377
⇒ x = 3.0377 - 1 = 2.0377
When rounding the final answer to the nearest tenths, we get x = 2 acres.
When rounding the final answer to the nearest thousand, we get x = 2.038 acres.
Thus, for an average intake of 2200 calories per day, the number of acres of land owned is approximately 2 acres.
