Water is pumped out of the conical tank with vertex down and radius 8 ft and height 20 ft. If the volume is decreasing at a rate of 4 ft^3sec :
how fast is the depth of the water decreasing when the water is 9 ft deep? (Note: Don't approximate the answer and state its exact value in terms of π.)
Answers
It took approximately 151 seconds to decrease 9 ft water in conical tank.
The volume of a conical tank with vertex down and radius 8 ft and height 20 ft is V = (1/3)πr²h
When the water is 9 ft deep
= (1/3) ×3.14×(8)²×(9)
= 602.88 ft³
We know that the rate of change of volume is 4 ft³/sec. So, the rate of change of depth can be calculated as follows:
Rate of change of depth (dh/dt) = Volume of tank/4 ft³ per sec
= 602.88/4
= 150.72 sec
Therefore, it took approximately 151 seconds to decrease 9 ft water in conical tank.

What is the standard deviation of the exponential distribution whose density function is f(x)=10*e^(-10x)?
Answers
The standard deviation of the exponential distribution is of 0.1.
-----------------
The exponential probability distribution, with mean and standard deviation m, is described by the following equation:
\(f(x) = \mu e^{-\mu x}\)
In which \(\mu = \frac{1}{m}\) is the decay parameter.
-----------------
The distribution is described by:
\(f(x) = 10e^{-10x}\)
Which has \(\mu = 10\)Thus, the mean and standard deviation are given by:
\(m = \frac{1}{\mu} = \frac{1}{10} = 0.1\)
The standard deviation is of 0.1.
A similar problem is given at https://brainly.com/question/17039711
We are required to find the standard deviation of the exponential distribution.
The standard deviation of the exponential distribution whose density function is f(x)=10*e^(-10x) is 0.1.
By convention, exponential probability distributions have density function in the form:
f(X) = f(x)=μ*e^(-μx)............... equation 1.
Where μ = decay parameter.
However, the decay parameter is related to the standard deviation of the distribution by the formular:
μ = 1/m
Where m = Standard deviation of the distribution.
Therefore, by comparison of equation 1 with f(x)=10*e^(-10x).
It is evident that the decay parameter, μ = 10
Therefore, the standard deviation, m = 1/μ = 1/10 = 0.1.
The standard deviation of the exponential distribution whose density function is f(x)=10*e^(-10x) is 0.1

draw the dot plot of the distribution of possible data values that has the largest possible standard deviation (there were ten people at the talk, so there should be ten dots on your dot plot)
Answers
The dot plot consists of ten dots, each representing the data value of a single person at the talk. The data values are spread out as far as possible, resulting in the largest possible standard deviation.
A dot plot is a graph that is used to represent the distribution of data. It consists of dots, each of which represents a single data value. In this case, the dot plot represents the distribution of possible data values from a talk with ten people. To achieve the largest possible standard deviation, the data points should be spread out as far as possible. Each dot should be placed on the graph in such a way that the difference between any two adjacent data points is maximized. This is done by placing the highest and lowest values at opposite ends of the graph, and then evenly spacing out the remaining data points in between. All of this should result in the largest possible standard deviation of the data set.

If you can buy one bunch of seedless green grapes for $2, then how many can you buy with $18?
Answers
If you can buy 1 bunch of seedless green grapes for $2, then $18 we can buy 9 bunches.
The concept used here is a simple division to find out how many bunches of seedless green grapes can be purchased with a given amount of money.
In this case, we know the cost of one bunch of seedless green-grapes ($2) and we are given a total amount of money ($18) that we can spend on grapes. We can use division to find out how many bunches we can buy with that amount.
⇒ Number of bunches = ($18)/($2) per bunch,
⇒ Number of bunches = 9 bunches;
Therefore, with $18, you can buy 9 bunches of seedless green grapes.

The values of x and y are proportional. proportionality (k) and find the missing values. 2. UX x 6 15 9 y 42 200 d. X 14 y 21 6 15 3 7 8 Determine the constant of proportionality
Answers
Step-by-step explanation:
To determine the constant of proportionality (k) in a proportional relationship, we need to compare corresponding values of x and y and calculate the ratio between them.
Let's examine the given values:
2. UX: x 6 15 9 y 42 200
To find the constant of proportionality (k), we can take any pair of corresponding values and calculate their ratio. Let's choose the first pair: (6, 42).
k = y / x
k = 42 / 6
k = 7
So, the constant of proportionality (k) is 7.
Now, let's find the missing values for the second set of values:
d. X: 14 y: 21 6 15 3 7 8
Since we know the constant of proportionality is 7, we can calculate the missing values of y by multiplying each corresponding x value by 7.
Missing values for y:
- For x = 21, y = 21 * 7 = 147
- For x = 6, y = 6 * 7 = 42
- For x = 15, y = 15 * 7 = 105
- For x = 3, y = 3 * 7 = 21
- For x = 7, y = 7 * 7 = 49
- For x = 8, y = 8 * 7 = 56
Therefore, the missing values of y are: 147, 42, 105, 21, 49, and 56.
midpoint between (-5, 4) and (7, -5)

Answer:
(1, -1/2)
Step-by-step explanation:
Find the midpoint by finding the averages of the x coordinates and y coordinates:
(-5 + 7) / 2
2 / 2 = 1 (x coordinate)
(4 - 5) / 2
-1 / 2 = -1/2 (y coordinate)
So, the midpoint is (1, -1/2)
The population of mosquitoes in a certain area increases at a rate proportional to the current population, and in the absence of other factors, the population doubles each week. There are 200,000 mosquitoes in the area initially, and predators (e.g. birds, bats) eat 20,000 mosquitoes/day. Determine the population of mosquitoes in the area at any given time.
So far, I have used the equation, P = P0 e^-kt The population of mosquitoes in a certain area inc where P0=200,000 and P(7)=400,000 (I figured time should be measured in days since you are given the number of mosquitoes eaten per day) to solve for k:
400,000 = 200,00 e^-k(7) >> K=-ln(2)/7=-.099
Using that, I figured I should put that into the differential equation (change in population = birthrate - deathrate)
dp/dt = kP - 20,00t ---> dp/dt = -099P - 20,000t
I thought I knew how to solve this and everything, but once I got an answer and plugged in different times, the model says the population decreases, which doesn't seem to make sense. So please check my reasoning up to this point and show the solution so I can check mine.
Answers
The equation you used is correct, but the differential equation does not include the growth rate. The growth rate is proportional to the current population, so the differential equation should look like this: dp/dt = kP - 20,000t
dp/dt = kP - 20,000t , Where k is the growth rate. To solve this equation, we can use the separation of variables: dp/P = kdt - 20,000tdt
Integrating both sides, we get:
ln|P| = kt - 20,000t^2/2 + C, Where C is the integration constant. To find C, we can use the initial population of 200,000:
ln|200,000| = -0.099t - 20,000t^2/2 + C
=>C = ln|200,000| + 0.099t + 20,000t^2/2 .Therefore, the population of mosquitoes at any given time t is:
P = 200,000e^(-0.099t - 20,000t^2/2 + ln|200,000| + 0.099t + 20,000t^2/2) = 200,000e^(ln|200,000|) = 200,000

Calculate the stamp duty payable on properties whose purchase price is K45 000. (1 mark) Answer: Calculate the stamp duty payable on properties whose purchase price is K150 000. (1 mark) Answer:
Answers
9. The stamp duty payable on a property with a purchase price of K45,000 is K1,350.
10. The stamp duty payable on a property with a purchase price of K150,000 is K7,500.
To calculate the stamp duty payable on properties with a purchase price of K45,000 and K150,000, we need to apply the corresponding rates of stamp duty based on the given information.
Given:
Value of Property:
Up to K35,000: Stamp Duty Rate - 2%
K35,000 to K70,000: Stamp Duty Rate - 3%
K70,000 to K140,000: Stamp Duty Rate - 4%
Over K140,000: Stamp Duty Rate - 5%
9. Calculate the stamp duty payable on properties whose purchase price is K45,000:
Since the purchase price of K45,000 falls within the range of K35,000 to K70,000, the stamp duty rate applicable is 3%.
Stamp Duty Payable = Purchase Price * Stamp Duty Rate
= K45,000 * 3%
= K45,000 * 0.03
= K1,350
Therefore, the stamp duty payable on a property with a purchase price of K45,000 is K1,350.
10. Calculate the stamp duty payable on properties whose purchase price is K150,000:
Since the purchase price of K150,000 is above K140,000, the stamp duty rate applicable is 5%.
Stamp Duty Payable = Purchase Price * Stamp Duty Rate
= K150,000 * 5%
= K150,000 * 0.05
= K7,500
Therefore, the stamp duty payable on a property with a purchase price of K150,000 is K7,500.
