For f(x) =2x, find a formula for the Riemann sum obtained by dividing the interval [2.5] subintervals and using the right hand endpoint for each ck. Simplify the sum and take the limit as n--> infinity to calculate the area under the curve over [2,5]
please show all of your work as be as descriptive as you can I appreciate your help thank you!
Answers
The area under the curve over [2,5] is 24.
Given function is f(x) = 2xIntervals [2, 5] is given and it is to be divided into subintervals.
Let us consider n subintervals. Therefore, width of each subinterval would be:
$$
\Delta x=\frac{b-a}{n}=\frac{5-2}{n}=\frac{3}{n}
$$Here, we are using right-hand end point. Therefore, the right-hand end points would be:$${ c }_{ k }=a+k\Delta x=2+k\cdot\frac{3}{n}=2+\frac{3k}{n}$$$$
\begin{aligned}
\therefore R &= \sum _{ k=1 }^{ n }{ f\left( { c }_{ k } \right) \Delta x } \\&=\sum _{ k=1 }^{ n }{ f\left( 2+\frac{3k}{n} \right) \cdot \frac{3}{n} }\\&=\sum _{ k=1 }^{ n }{ 2\cdot\left( 2+\frac{3k}{n} \right) \cdot \frac{3}{n} }\\&=\sum _{ k=1 }^{ n }{ \frac{12}{n}\cdot\left( 2+\frac{3k}{n} \right) }\\&=\sum _{ k=1 }^{ n }{ \frac{24}{n}+\frac{36k}{n^{ 2 }} }\\&=\frac{24}{n}\sum _{ k=1 }^{ n }{ 1 } +\frac{36}{n^{ 2 }}\sum _{ k=1 }^{ n }{ k } \\&= \frac{24n}{n}+\frac{36}{n^{ 2 }}\cdot\frac{n\left( n+1 \right)}{2}\\&= 24 + \frac{18\left( n+1 \right)}{n}
\end{aligned}
$$Take limit as n → ∞, so that $$
\begin{aligned}
A&=\lim _{ n\rightarrow \infty }{ R } \\&= \lim _{ n\rightarrow \infty }{ 24 + \frac{18\left( n+1 \right)}{n} } \\&= \boxed{24}

Given function f(x) = 2x. The interval is [2,5]. The number of subintervals, n is 3.
Therefore, the area under the curve over [2,5] is 21.
From the given data, we can see that the width of the interval is:
Δx = (5 - 2) / n
= 3/n
The endpoints of the subintervals are:
[2, 2 + Δx], [2 + Δx, 2 + 2Δx], [2 + 2Δx, 5]
Thus, the right endpoints of the subintervals are: 2 + Δx, 2 + 2Δx, 5
The formula for the Riemann sum is:
S = f(c1)Δx + f(c2)Δx + ... + f(cn)Δx
Here, we have to find a formula for the Riemann sum obtained by dividing the interval [2.5] subintervals and using the right hand endpoint for each ck. The width of each subinterval is:
Δx = (5 - 2) / n
= 3/n
Therefore,
Δx = 3/3
= 1
So, the subintervals are: [2, 3], [3, 4], [4, 5]
The right endpoints are:3, 4, 5. The formula for the Riemann sum is:
S = f(c1)Δx + f(c2)Δx + ... + f(cn)Δx
Here, Δx is 1, f(x) is 2x
∴ f(c1) = 2(3)
= 6,
f(c2) = 2(4)
= 8, and
f(c3) = 2(5)
= 10
∴ S = f(c1)Δx + f(c2)Δx + f(c3)Δx
= 6(1) + 8(1) + 10(1)
= 6 + 8 + 10
= 24
Therefore, the Riemann sum is 24.
To calculate the area under the curve over [2, 5], we take the limit of the Riemann sum as n → ∞.
∴ Area = ∫2^5f(x)dx
= ∫2^52xdx
= [x^2]2^5
= 25 - 4
= 21
Therefore, the area under the curve over [2,5] is 21.

the scores on a standardized test are normally distributed with a mean of 90 and standard deviation of 15. what test score is 0.1 standard deviations above the mean?
Answers
The test score is 91.5.
z-score:
A z-score is the number of standard deviations from the mean value of the reference population.
Here we have to find the test score.
Mean(μ) = 90
Standard deviation(б) = 15
z-score = 0.1
Formula for z-score:
z = X - μ / б
Now putting the values in the equation:
0.1 = X - 90 / 15
1.5 = X - 90
X = 91.5
Therefore the test score is 91.5.

How can you quickly determine the number of the roots of a polynimial will have by looking at the equation
Answers
The leading term of the equation can be used to predict how many roots a polynomial will have.
To find the number of roots in a polynomial, look at the equation's leading phrase. A word with the most power is said to be leading.
Think about the linear formula x – 4 = 0.
The equation's highest power, 1, will only have one root.
We can check it by simplification
x = 4
The equation has only one root x = 4.
Consider the quadratic equation
10t² - t - 3 = 0
The equation's highest power, 2, will have two roots.
By simplifying and applying the middle term splitting approach, we can verify it.
10t² + 5t - 6t - 3 = 0
Taking out the common terms
5t (2t + 1) - 3 (2t + 1) = 0
(2t + 1) (5t - 3) = 0
t = -1/2 and t = 3/5
So the equation has two roots.

Answers
To calculate the 95% confidence interval for the difference in mean weekly sales for the two movie theaters, follow these steps:
Step 1: Gather the data for the random sample of 25 weeks.
Step 2: Calculate the mean and standard deviation for each movie theater's weekly sales.
Step 3: Calculate the difference in mean weekly sales for the two movie theaters (subtract the mean of theater 2 from the mean of theater 1).
Step 4: Calculate the standard error of the difference by taking the square root of [(standard deviation of theater 1^2 / number of weeks) + (standard deviation of theater 2^2 / number of weeks)].
Step 5: Determine the critical value for a 95% confidence interval using a t-table or calculator (for a two-tailed test with 24 degrees of freedom, the critical value is approximately 2.064).
Step 6: Multiply the critical value by the standard error to get the margin of error.
Step 7: Calculate the lower and upper bounds of the confidence interval by subtracting and adding the margin of error from the difference in mean weekly sales.
The result will be the 95% confidence interval for the difference in mean weekly sales for the two movie theaters.

The sum of variables m and n is negative fifteen, This implies;
\(m+n=-15----i\)One number is seven less than the other implies;
\(\begin{gathered} m-n=7----ii \\ \text{Where;} \\ m\text{ is the greater number and} \\ n\text{ is the lesser number} \end{gathered}\)Hence, the system of equations that describe the situation is
\(\begin{gathered} m+n=-15----i \\ m-n=7-----ii \end{gathered}\)To find the two numbers, use the elimination method.
\(\begin{gathered} (i)+(ii) \\ \Rightarrow m+m+n+(-n)=-15+7 \\ 2m=-8 \\ \text{Divide both sides by 2} \\ \frac{2m}{2}=-\frac{8}{2} \\ m=-4 \end{gathered}\)To get n, substitute m = -4 into (i)
\(\begin{gathered} \text{Recall (i)} \\ m+n=-15---i \\ \Rightarrow-4+n=-15 \\ \text{Collect the like terms} \\ n=-15+4 \\ n=-11 \end{gathered}\)Therefore, the two numbers = -4, -11

In pentagon $MATHS$, $\angle M \cong \angle T \cong \angle H$ and $\angle A$ is supplementary to $\angle S$. How many degrees are in the measure of $\angle H$?
Answers
Answer:
H = 120°
Step-by-step explanation:
The sum of the internal angles of a polygon with n sides is given by the formula:
S = (n-2)*180
So, for a pentagon, we have n = 5, then:
S = (5-2)*180 = 540°
So we have that:
M + A + T + H + S = 540° (eq1)
M = T = H (eq2)
A + S = 180° (eq3)
Using the second and third equation in the first one, we have:
H + H + H + 180 = 540
3H = 360
H = 120°

We need to find the greatest common factor (GCF) for all four of these fractions.
To find the GCF of a fraction, you must list the factors of the numerator and denominator, then determine the largest factor that both numbers have in common.
Remember, factors are numbers that we multiply together to get another number.
------------------------------------------------------
Let's find the GCF of 24/30.
First, we have to list the factors of the numerator and the denominator.
24: 1, 2, 3, 4, 6, 12, 24
30: 1, 2, 3, 5, 6, 10, 15, 30
Then, we determine the largest factor that both numbers have in common.
The largest factor that they have in common is 6. So, the GCF is 6.
------------------------------------------------------
GCF of 21/30.
21: 1, 3, 7, 21
30: 1, 2, 3, 5, 6, 10, 15, 30
The largest factor that they have in common is 3. So, the GCF is 3.
------------------------------------------------------
GCF of 28/32.
28: 1, 2, 4, 7, 14, 28
32: 1, 2, 4, 8, 16, 32
The largest factor that they have in common is 4. So, the GCF is 4.
------------------------------------------------------
GCF of 20/25.
20: 1, 2, 4, 5, 10, 20
25: 1, 5, 25
The largest factor that they have in common is 5. So, the GCF is 5.

For x = 4, the residual value is -7.586. Therefore, the correct option is b.
We are required to find the residual value for x = 4 using the given data and the LSRL ý = 20.47 + 3.486x.
To find the residual value, follow these steps:
1. Find the predicted value for x = 4 using the LSRL equation.
ý = 20.47 + 3.486(4) = 20.47 + 13.944 = 34.414
2. Locate the actual value of y when x = 4 in the data.
x: 1 2 3 4 5 6
y: 43 37 29 22 22 11
For x = 4, the actual y value is 22.
3. Calculate the residual value using the formula:
Residual = Actual value - Predicted value
Residual = 22 - 34.414 = -7.586
Hence, the residual value for x = 4 is -7.586, which corresponds to option b: -7.586.
Note: The question is incomplete. The complete question probably is: Suppose you have the following data: x 1 2 3 4 5 6 y 43 37 29 22 22 11 and the lsrl is ý = 20.47 + 3.486. Find the residual value for x = 4. a) 34.414 b) -7.586 c) 42 d) 7.586 e) None of the above.

Add 2 to each side
45+2 = s-2+2
47 =s
Walter bought 2,000 cubic millimeters of clay for his sculpture. Now that he has molded the cone and the sphere, he wants to use the rest for decorations. How much clay does he have left for decorations?
Answers
Answer:
Step-by-step explanation:
Let's first find the total volume of clay used for the cone and the sphere:
For the cone, we need the formula for the volume of a cone: Vcone = (1/3)πr^2h, where r is the radius of the base and h is the height.
Let's assume the cone has a radius of 5 millimeters and a height of 10 millimeters. Then, the volume of the cone is:
Vcone = (1/3)π(5^2)(10) = (1/3)π(250) = 83.33 cubic millimeters (rounded to two decimal places)
For the sphere, we need the formula for the volume of a sphere: Vsphere = (4/3)πr^3, where r is the radius.
Let's assume the sphere has a radius of 4 millimeters. Then, the volume of the sphere is:
Vsphere = (4/3)π(4^3) = (4/3)π(64) = 268.08 cubic millimeters (rounded to two decimal places)
The total volume of clay used for the cone and the sphere is:
Vcone + Vsphere = 83.33 + 268.08 = 351.41 cubic millimeters (rounded to two decimal places)
To find the amount of clay left for decorations, we can subtract this volume from the original amount of clay:
2000 - 351.41 = 1648.59 cubic millimeters (rounded to two decimal places)
Therefore, Walter has 1648.59 cubic millimeters of clay left for decorations.
